[0025] The present invention also relates to a method for acquiring 2D or 3D data using an acquisition kit according to the present invention, the method being: a) The user may optionally select a spacer from a set of available spacers, preferably based on the personalization mark and / or user form supported by the available spacer; b) The acquisition kit is preferably assembled by the user, in particular by attaching the mobile phone to the adapter and optionally the spacer to the adapter; c) The end of the spacer defining the oral opening is inserted into the user's oral cavity by the user, preferably by inserting the flange of the spacer between the user's lips and the user's teeth; d) The user positions the oral opening on the opposite side of the tooth from which the data should be acquired; e) The mobile phone is preferably operated by the user to acquire the 2D or 3D data; f) Arbitrarily change the position of the oral opening, for example, by rotating it around the user and / or by rotating it from bottom to top, and then return to step e); g) The acquisition kit is preferably optionally disassembled by the user; h) Optionally, clean and / or disinfect the spacer, or clean only the spacer. This includes the following steps.

[0026] Preferably, in step d), the spacer is positioned so as not to rest on the gums, on the teeth, or on any orthodontic appliances fitted to the teeth. Preferably, the spacer is in contact only with the inner surfaces of the lips and cheeks.

[0027] The distal flange may be more than 1 mm, more than 2 mm, more than 3 mm, and / or less than 10 mm from the tooth, preferably less than 8 mm.

[0029] In step f), the rotation may be from top to bottom or bottom to top around the horizontal axis at the service position. The degree of rotation is preferably more than 10°, more than 20°, and / or less than 60°, especially if step e) is performed facing the user, where the optical axis is horizontal.

[0030] By repeating steps e) and f), the user obtains 2D or 3D data of different teeth with different orientations.

[0031] definition

[0032] "User" means any person who may use a kit according to the present invention, regardless of whether that person is ill or undergoing treatment. Kits according to the present invention may also be used for animals other than humans.

[0033] "Dental healthcare professional" refers to a dentist, orthodontist, or orthodontic manufacturer.

[0034] "Mobile phone" refers to a device, such as an iPhone. (登録商標) Such devices typically weigh less than 500g and are equipped with a camera with a lens that allows the device to take videos or photographs, or a scanner that allows the device to acquire three-dimensional digital models. The mobile phone can also exchange and display data with another device located more than 500km away from the mobile phone.

[0035] The "default configuration" of the mobile phone consists of all the settings of the mobile phone that were defined before the mobile phone was first used.

[0036] "Image" refers to a two-dimensional image, such as a photograph. Images consist of pixels.

[0037] A "video" is considered a set of multiple photographs.

[0038] "Model" refers to a three-dimensional digital model. A model consists of a set of multiple voxels.

[0039] The mobile phone enables the acquisition of "extraoral" data, that is, data acquisition without inserting the phone's lens into the user's mouth. The "2D data" acquired by the mobile phone is images, and more specifically, conventionally, photographs and videos. The "3D data" acquired by the mobile phone is data that provides coordinates in three-dimensional space. The "3D data" is preferably a three-dimensional digital model.

[0040] A "retractor," or dental retractor, is an instrument used to roll back the lips.

[0041] The retractor comprises an upper flange and a lower flange, and / or a right flange and a left flange, extending around the opening and intended to be inserted between the teeth and the lip. In the service position, the user's lip rests on these flanges, and thus the teeth become visible through the opening of the retractor. Thus, the retractor allows the teeth to be viewed without the lip obstructing the view.

[0042] However, the teeth are not fixed on the retractor, and therefore the user can change the teeth visible through the opening of the retractor by rotating their head relative to the retractor. The user can also change the distance between their dental arches. In particular, the retractor does not push the teeth in a way that separates the two jaws.

[0043] In one embodiment, the retractor is configured to elastically separate the upper lip and the lower lip so as to expose the teeth visible through the opening of the retractor.

[0044] In one embodiment, the retractor is configured such that the distance between the upper flange and the lower flange, and / or the distance between the right flange and the left flange, is constant.

[0045] The retractor is described, for example, in International Patent Application No. PCT / EP2015 / 074896, U.S. Patent No. US6923761, or U.S. Patent Application Publication No. US2004 / 0209225.

[0046] To “attach” one part to another means to establish a physical connection between the two parts, so that when one of them moves, the other part will eventually move as well. A part that is attached to another part by translation, rotation, or via a ball joint is “attached” to that other part. The attachment may be “permanent” or “removable,” depending on whether the two parts are designed to be disassembled by the user, preferably by hand. The attachment may be rigid or not, depending on whether it allows relative movement between the two attached parts. An element that is made integrally with another element is considered to be “attached” to that other element.

[0047] Two parts are "elastically movable" relative to each other if, under the action of a force, their relative positions are changed, and when the force is removed, the two parts return to their original relative positions.

[0048] A "corner edge" on a surface is a line that has a length of more than 1 cm on the surface and is formed by a point where the line with the greatest gradient has a change in gradient greater than 45°, and is also referred to as a "break in gradient". By extension, this means that the angle of the corner edge is greater than 45°, or that the surface has a break in gradient greater than 45°. If the corner edge defines a concave shape, then the corner edge is a concave angle. For example, Figure 15 shows any point M on line segment A. A The diagram illustrates a surface S1 where the line segment G with the greatest gradient has a break in the gradient of θ. If the angle θ is greater than 45° at all points on the line segment A, then the line segment A is a corner edge. In practice, it is possible to measure the change in gradient between two points M1 and M2 separated by a distance of 3 mm on the line with the greatest gradient, where the distance of 3 mm is measured along the line.

[0049] The “assembled position” is the position in which the mobile phone is rigidly attached to the adapter of the kit and the spacer is rigidly attached to the adapter.

[0050] The “acquisition position” is an assembled position in which the lens of the mobile phone can see at least a portion, preferably all, of the oral cavity opening through the adapter opening and the acquisition opening.

[0051] The "service position" is the position in which the spacer of the kit is partially inserted into the user's oral cavity at the acquisition position, as shown in Figure 12.

[0052] The "closed mouth" position is the occlusal position where the user's upper and lower teeth are in contact.

[0053] The position of "open mouth" is the position where the mouth is completely open.

[0054] Unless otherwise stated, modifiers used to define spatial position or orientation, such as “horizontal,” “vertical,” “bottom,” “top,” “down,” “right,” and “left,” are defined, for clarity, relative to the service position as seen by the user with the user’s head straight and their lips positioned around the oral opening of the spacer.

[0055] For example, the vertical axis is the axis that is perpendicular to the service location.

[0056] The lateral ends (right and left) of the distal flange are the points on the distal flange that are furthest to the right and left of the user at the service position.

[0057] Unless otherwise specified, the modifiers “outside” and “inside” refer to a volume or closed contour and specify elements outside that volume, for example, outside the chamber or outside the closed contour. For example, the outer surface of a tubular body is the surface exposed to the outside of the tubular body.

[0058] The adjectives "first" and "second" are used merely for clarity.

[0059] For clarity, at the service position, an axis or direction that extends horizontally and perpendicular to the general plane of the oral cavity opening is referred to as X i where "i" is an index referring to the part related by this axis or this direction. At the service position, an axis or direction that extends vertically is referred to as Z i where "i" is an index referring to the part related by this axis or this direction. At the service position, the axis X i and the axis Z i an axis or direction that extends perpendicular to them is referred to as Y i where "i" is an index referring to the part related by this axis or this direction. Therefore, for the user, the axes X i Y i Z i are the anteroposterior axis, the left - right axis, and the vertical axis respectively.

[0060] The axis of the opening is an axis passing through its center and perpendicular to the general plane of the opening.

[0061] The first straight line and the second straight line are perpendicular to each other when the first plane and the second plane perpendicular to the first straight line and the second straight line respectively are perpendicular to each other.

[0065] In various diagrams, identical or similar components are specified using the same reference.

[0066] These figures are provided for illustrative purposes only. They are not exhaustive. [Modes for carrying out the invention]

[0067] The kit 10 shown in Figure 1 includes a mobile phone 12 and a holder 14.

[0068] mobile phone

[0069] Any conventional mobile phone will be used.

[0070] The mobile phone 12 is a personal device that is conventionally shaped like a parallelepiped and conventionally equipped with a camera.

[0071] Mobile phones are typically, As shown in Figure 6, the front surface 121 is equipped with a lens, preferably a flash 18. A rear panel 122 having a screen 20, and Side 22 that defines the thickness of the mobile phone and connects the front and back It has.

[0072] The front and back surfaces are conventionally rectangular, generally parallel, and have the same dimensions. Their length L 12 Their width is typically 8-20 cm. As shown in Figure 1, their width l 12 They are typically 4-10 cm long.

[0073] The thickness of this mobile phone is typically between 4mm and 15mm.

[0074] The screen 20 substantially covers the entire back. The screen serves as an interface for the user. In particular, it allows the user to visualize what the lens 16 is "seeing," i.e., the "field of view" seen by the lens. Preferably, the screen 20 is touch-sensitive and allows control of the mobile phone's functions.

[0075] Lens 16 is conventionally positioned with the optical axis X perpendicular to the front. 16 It has the capability to acquire 2D or 3D data. In particular, the lens enables the acquisition of color photographs and / or infrared photographs. Infrared photographs have the advantage of enabling teeth to be shown with excellent contrast.

[0076] Lens 16 typically has a diameter greater than 1 mm and less than 15 mm.

[0077] The lens is often located in the center of the mobile phone. It is typically positioned near one side of the front panel, for example, less than 3 cm from the shorter side of the front panel, conventionally somewhere in the middle of this side, or at one of the corners of the front panel, for example, less than 1 cm from one of the corners.

[0078] The mobile phone 12 may have multiple lenses on its front, for example, two, more than two, more than three, more than four lenses 16, and / or fewer than eight or fewer than six lenses.

[0079] The flash 18 may be close to the lens 16, preferably less than 4 cm, less than 3 cm, less than 2 cm, or less than 1 cm and / or more than 1 mm away from the lens 16. The mobile phone 12 may have multiple flashes on its front, for example more than 2, more than 3, more than 4, and / or less than 8, or less than 6 flashes.

[0080] In a preferred embodiment, the mobile phone includes computer software for guiding the user during operation, for example, instructing the user on how to assemble or use a kit, or telling the user the position and / or orientation to give the holder for taking a particular photograph.

[0081] The mobile phone 12 is attached to the holder 14, preferably in a detachable manner.

[0082] holder

[0083] The holder 14 has two purposes. The holder is, Push back the user's lips, separating them from the teeth, and Positioning and orienting the mobile phone relative to the tooth. To make it easier.

[0084] The holder includes a spacer 24 and an adapter 26.

[0085] In the assembled position, the spacer 24 and the adapter 26 together define a chamber 28 (see Figure 3) that opens outward, preferably exclusively, through the oral opening Oo on the opposite side of the lens 16 of the mobile phone 12 and through the adapter opening Oa.

[0086] The chamber 28 is preferably substantially tubular, and preferably along the X axis. 28 It is a straight line having [a certain characteristic].

[0087] The length of the chamber 28, measured along the axis Xa of the adapter opening, is preferably more than 3 cm, preferably more than 5 cm, and / or less than 25 cm, preferably less than 20 cm, preferably less than 15 cm, preferably less than 10 cm, preferably less than 8 cm, and preferably less than 7 cm.

[0088] The length of the chamber 28 is preferably constant in the assembled position.

[0089] Preferably, the chamber 28 opens to the outside only through the oral opening Oo and the adapter opening Oa, and more preferably, the mobile phone 12 closes the adapter opening Oa. Advantageously, the light level in the external environment does not affect the acquisition of data (images or 3D models) by the mobile phone.

[0090] Preferably, the holder does not have any artificial lighting means, and the illumination of the oral opening is provided solely by the flash of the mobile phone 12.

[0091] The oral opening defined by the spacer 24 may extend to a vertical plane Po passing through its center Co, preferably along the axis X connecting the center of the oral opening Oo and the center of the acquired opening Oa'. 24 It is perpendicular to it.

[0092] However, preferably, as shown in Figure 16, the oral opening partially extends outward from the surface Po on the side facing the body 40 of the spacer, i.e., on the side of the user in the service position.

[0093] Preferably, the oral opening Oa is curved, preferably exclusively around the vertical axis Zo at the service position, so as to be close to the teeth at the service position.

[0094] The distal flange 46, preferably the spacer 24, is preferably symmetrical with respect to a vertical plane that coincides with the sagittal plane at the service position. The axis Zo is preferably contained within this vertical plane, and the axis X 24It is perpendicular to it.

[0095] Preferably, the radius of curvature with respect to the vertical axis Zo, particularly in the region of the vertical plane, is greater than 20 mm, preferably greater than 30 mm, preferably greater than 40 mm, preferably greater than 45 mm, and / or less than 80 mm, preferably less than 70 mm, preferably less than 60 mm, preferably less than 55 mm, preferably about 50 mm.

[0096] Preferably, the radius of curvature varies by less than 30%, preferably less than 20%, preferably less than 10%, or is even substantially constant along the distal flange, i.e., across the distal flange in the top view as shown in Figures 16A and 16C.

[0097] A radius of curvature of 47mm to 58mm is particularly suitable.

[0098] Viewed from above, the teeth of the dental arch have curvature, and the radius of this curvature is considerably larger in a C-shape towards the back of the mouth. When the curvature of the oral opening aligns with the curvature of the teeth, the holder is particularly stable in the service position, but this stability impairs rotation for the user. Moreover, when the user performs such rotation, it results in the oral opening moving away from the teeth.

[0099] In a particularly advantageous embodiment of the present invention, the curvature of the oral cavity opening prevents the distal flange 46 from conforming to the tooth.

[0100] Such curvature of the oral opening offers several additional advantages when it comes to acquiring 2D or 3D data from outside the oral cavity.

[0101] Such curvature has been shown in particular through testing to limit the risk of the lip obstructing the oral opening beyond the distal flange when the kit is positioned to the right or left of the user and facing the molars or premolars (lateral view position) in order to acquire 2D or 3D data, especially photographs. In these positions to the right or left of the user, this curvature also prevents the spacer from coming into contact with, for example, an attachment of an orthodontic appliance. This curvature also prevents the spacer from pinching the cheek when the oral opening is returned to face the incisors.

[0102] Studies have also shown that this curvature limits the pulling of the lips when viewed from a lateral position, thereby improving comfort and, consequently, improving compliance with any orthodontic treatment.

[0103] "Curved" means following a general shape that allows it to follow an arc, i.e., a shape that is at least part of a "C". Preferably, the curvature is continuous and there are no breaks in the gradient so as not to create concave corner edges.

[0104] The adapter opening Oa may be defined by the adapter 26 and / or the spacer 24.

[0105] Preferably, the adapter opening Oa is defined by the adapter 26, and the spacer 24 defines the acquisition opening Oa' (see Figure 2).

[0106] The area of ​​the oral opening is preferably 500 mm². 2 More preferably 800mm 2 More preferably 1000mm 2 More preferably 1100mm 2 More preferably 1200mm 2 More preferably 1300mm 2 Over, and / or 2000mm 2 Less than 1800 mm, preferably 1800 mm 2 Less than 1600 mm, preferably 1600 mm 2 Less than 1500mm, preferably 1500mm2 Less than 1400mm, preferably 1400mm 2 It is less than.

[0107] Preferably, the oral opening is shaped such that the lens of the mobile phone can see several teeth, preferably more than two, more than three, more than four, more than five, and / or fewer than 32 teeth, through the acquisition opening.

[0108] The oral opening is preferably elliptical and has a length in the horizontal direction that is greater than its height in the vertical direction.

[0109] The length of the oral opening is preferably more than 50 mm, more preferably more than 60 mm, more preferably more than 70 mm, and / or less than 100 mm, more preferably less than 90 mm.

[0110] The height of the oral opening is preferably adapted to allow the user's mouth to close in the service position. The height of the oral opening is preferably greater than 20 mm, preferably greater than 25 mm, preferably greater than 30 mm, and / or less than 50 mm, preferably less than 40 mm.

[0111] The area of ​​the acquisition opening is preferably 500 mm². 2 More preferably 800mm 2 More preferably 1000mm 2 More preferably 1100mm 2 More preferably 1200mm 2 More preferably 1300mm 2 More preferably 1400mm 2 Ideally, 1500mm 2 Ideally, 1600mm 2 Over, and / or 2000mm 2 Less than 1900 mm, preferably 1900 mm 2 Less than 1800 mm, preferably 1800 mm 2 Less than 1700 mm, preferably 1700 mm 2 It is less than.

[0112] In a preferred embodiment, the spacer 24 has the shape of a tubular body that opens exclusively through the oral cavity opening Oo and the acquisition opening Oa'.

[0113] The oral cavity opening Oo and the acquisition opening Oa' are preferably coaxial.

[0114] Preferably, as schematically shown in Figure 9, the distance d between the acquisition opening Oa' of the spacer 24 and the adapter opening Oa in the assembled position is less than 3 cm, preferably less than 2 cm, preferably less than 1 cm, preferably less than 0.5 cm, preferably less than 0.2 cm, and preferably substantially zero. The distance d is also shown in Figure 14. Preferably, the acquisition opening Oa' of the spacer and the adapter opening Oa are coplanar. Advantageously, the spacer 24 forms a lining that protects the adapter from air, particularly saliva, expelled by the user. This improves hygiene.

[0115] Preferably, the acquisition opening Oa' of the spacer and the adapter opening Oa have substantially the same dimensions. Preferably, they are coaxial.

[0116] Preferably, as shown in Figure 10, one end 23 of the spacer 24 is housed in a housing 25, preferably of a complementary shape, preferably in a nested manner. The housing 25 defines the adapter opening Oa. Preferably, the spacer 24 penetrates this housing along its entire length.

[0117] At least the end of the spacer 24, preferably the entire spacer 24, is defined by a solid wall, i.e., the spacer opens to the outside only through the oral opening and the acquisition opening.

[0118] In one embodiment, the adapter 26 and the spacer 24 form an integrated assembly, where the adapter 26 is rigidly attached to the spacer 24 or is manufactured integrally with the spacer.

[0119] The adapter 26 is preferably rigidly and removably attached to the spacer 24.

[0120] Advantageously, adapter 26 can be used for multiple spacers.

[0121] Another advantage is that the spacer 24 can be cleaned or sterilized independently of the adapter.

[0122] In this embodiment in particular, the spacer 24 is preferably made of an autoclavable material, preferably an autoclavable material that can withstand autoclaving in an autoclave or dishwasher. Preferably, the spacer can be super-sterilized 50 times without degradation. Sterilization is considered to be achieved when the probability of isolating contaminants is less than 1 in 1,000,000, according to the sterility assurance level (SAL) of standard EN556.

[0123] Preferably, the adapter 26 is connected to the adapter 27, as shown in Figure 8. 26 Mounting part and spacer 27 24 The adapter is securely attached to the spacer 24 by a clip having a mounting portion. The adapter mounting portion and the spacer mounting portion interact with each other to provide a removable mounting for the adapter to the spacer. Therefore, the adapter mounting portion and the spacer mounting portion can be connected or disconnected, respectively, to attach the adapter to or remove it from the spacer.

[0124] Preferably, spacer mounting portion 27 24 It remains stationary on the spacer 24, or in other words, the spacer mounting portion 27 24 The adapter mounting portion is not designed to move during assembly and disassembly. Preferably, the spacer mounting portion 27 24 The adapter mounting portion does not deform during assembly and disassembly. Spacer mounting portion 27 24The adapter mounting part 27 26 It maintains its shape when connected and / or disconnected. For example, the spacer mounting portion 27 24 These can be formed in the walls of the spacer 24 that partitions the chamber 28 by material beads or by blind recesses. The spacer mounting portion is considered to retain its shape if no point on its surface moves by more than 1 mm during assembly and disassembly. Preferably, no point on the surface of the spacer mounting portion moves by more than 0.5 mm, more preferably more than 0.2 mm, during assembly and disassembly.

[0125] Spacer mounting portion 27 24 The static nature of the spacer may also be described as "passive," which advantageously allows for avoiding deformation of the spacer 24 during sterilization procedures. This feature is particularly advantageous when sterilization is not required, for example, when the adapter 26 is protected by the spacer 24.

[0126] Preferably, adapter mounting portion 27 26 It is movable relative to the rest of the adapter. For example, adapter mounting portion 27 26 These can be formed by claws that are adapted to hook onto the bead of the spacer material or to elastically fit into a recess in the spacer 24, as shown in Figure 8.

[0127] Adapter mounting section 27 26 It may also be part of an elastically deformable adapter, for example, beads of an elastically deformable material. In one embodiment, the adapter carries one or more beads, for example four beads, and is arranged to elastically fit into one or more individual recesses made on the outer surface of the spacer body during assembly.

[0128] Preferably, spacer mounting portion 27 24 and adapter mounting part 27 26Unlike elastic materials, such as elastomers, it is made of a rigid material, i.e., a material that cannot be deformed by being pressed by hand. Preferably, this material has a hardness greater than 70 Shore D and / or less than 100 Shore D.

[0129] Preferably, the kit, preferably at least the spacer 24, carries a personalized piece that carries a personalization mark 39, which is attached to the adapter 26 and / or the spacer 24, preferably in a removable manner.

[0130] The personalization mark 39 preferably includes an identifier that identifies the user and / or the dental professional's clinic and / or company, for example, a group of dental professionals.

[0131] In one embodiment, the user identifier is specific, that is, it enables the unique identification of a user. In other words, the user identifier is used only for that user.

[0132] Personalization mark 39 may also include information about the user's medical condition.

[0133] The personalization marks 39, in particular the personalization pieces, are preferably attached to the adapter 26 and / or spacer 24, and preferably removable, by the user or by a dental professional in charge of the user, for example, an orthodontist who previously fitted the orthodontic appliance actively or passively into the user's oral cavity.

[0134] The personalization mark may be attached by any means, in particular by one or more clips, one or more screws, one or more hook-and-loop tapes of Velcro®, one or more rubber bands, one or more magnets, one or more hooks, one or more bolts, one or more straps, one or more suction cups, or one or more adhesives.

[0135] The personalization mark is inscribed or engraved on the spacer or adapter, preferably on the spacer.

[0136] This engraving can be done, for example, on a cardboard spacer using a pen, such as an indelible marker, or by pad printing.

[0137] The identifier may consist, for example, of a color, alphanumeric characters, a geometric or non-geometric pattern, or a specific microstructure.

[0138] Personalization mark 39 may include aesthetic depictions, such as jewels, or humorous depictions, such as humorous depictions of cartoon characters.

[0139] Preferably, the personalization mark 39 is a different color or material from the spacer 24 and / or the adapter 26 that supports it.

[0140] The personalization mark 39 may represent, for example, more than 0.1%, more than 0.5%, more than 1%, more than 3%, and / or less than 90%, less than 50%, less than 20%, or less than 10% of the surface area of ​​the spacer 24 and / or the adapter 26 that carries it.

[0141] In one embodiment, the kit comprises several removable spacers, referenced in Figure 8 as 241 and 242, which may be assembled into an adapter 26 and have different oral openings and / or personalization marks, in particular personalized pieces. Advantageously, the adapter 26 may be used for multiple different people, where each person uses a spacer 24 unique to each person.

[0142] Advantageously, the user becomes more familiar with the kit, thereby encouraging them to use it. This improves compliance with procedures requiring the use of the acquisition kit according to the present invention.

[0143] Furthermore, the adapter may be used for multiple spacers, for example, each spacer being assigned to a child of the same family.

[0144] Spacer

[0145] The spacer 24 has the function of defining the distance between the mobile phone attached to the adapter 26 and the oral opening Oo, as well as the orientation of the mobile phone with respect to the oral opening. Therefore, advantageously, at the service position, the data acquired by the mobile phone 12 through the lens 16 (images or 3D models of the user's teeth) is acquired at a predetermined distance and orientation from the user's teeth. Preferably, the spacer 24 is configured such that this distance and lpmp orientation remain constant.

[0146] The spacer 24 is preferably symmetrical with respect to the horizontal and / or vertical planes.

[0147] The spacer 24 is equipped with a main body 40 and is open at both ends through the oral cavity opening Oo and the acquisition opening Oa'.

[0148] The main body 40 preferably has a constant or variable cross-section, preferably along the X axis. 24 The spacer has a general shape of a substantially straight tube, with an opening at its end through the center of the oral opening Oo and the center of the acquisition opening Oa'. The spacer 24 may have a general shape of a cylindrical tube or tapered tube, in particular, having a circular, elliptical, or polygonal, for example, rectangular cross-section.

[0149] Cross-section of spacer 24, i.e., axis X 24 Cross section X in a cross-sectional plane perpendicular to it 24Preferably, the tube has a substantially consistent general shape throughout, such as rectangular, elliptical, or circular.

[0150] Preferably, the spacer 24 has a shape such that, when the zoom function of the mobile phone 12 is not used in any way, the representation of the spacer 24 in the field of view seen by the lens 16 (indicated by two dotted lines branching from the lens 16 in Figures 9 and 10) occupies less than 50%, preferably less than 40%, preferably less than 30%, preferably less than 20%, preferably less than 10%, and preferably less than 5% of the surface area of ​​the field of view. In other words, in the image acquired by the mobile phone 12, the representation of the spacer 24 occupies a limited surface area.

[0151] Figure 13 provides an example of such a view. The spacer is indicated by the gray area.

[0152] An advantage is that this improves the accuracy of the usable zone representing the tooth.

[0153] Preferably, the representation of the spacer 24 in the field of view shows a portion of the spacer 42 that extends exclusively to less than 5 cm, less than 3 cm, less than 2 cm, and less than 1 cm from the oral opening Oo, as shown in Figure 9.

[0154] An advantage of this is that it improves the focus on the tooth.

[0155] To limit the surface area occupied by the representation of the spacer 24 when viewed through the lens 16, it is possible to limit the length of the spacer 24. However, the spacer 24 must have the minimum size that allows for focusing.

[0156] The "acquisition configuration" consists of all the settings of the mobile phone that determine the acquisition of 2D or 3D data by the lens 16 of the mobile phone. In one embodiment, the acquisition configuration is the default setting of the mobile phone 12.

[0157] Instead of limiting the length of the spacer 24, or in addition to limiting the length of the spacer 24, the mobile phone can be configured according to an acquisition configuration particularly suited to the use of the acquisition kit in order to limit the surface area occupied by the representation of the spacer 24 in the field of view seen by the lens 16.

[0158] The acquisition configuration is preferably defined by the mobile phone itself, i.e., automatically.

[0159] Preferably, the acquisition configuration is obtained by adjusting the zoom of the mobile phone. Preferably, the zoom is adjusted by the mobile phone without user intervention for this purpose. For example, the zoom may be adjusted when a program loaded on the mobile phone for using the acquisition kit is launched.

[0160] Preferably, the acquisition configuration, preferably zoom, is automatically adjusted according to the spacer, for example, according to its shape, or its length, or its width. In one embodiment, the spacer is recognized by the mobile phone, for example, by reading a mark placed on the spacer, or by analyzing the field of view visible to the lens that shows a portion of the spacer at the acquisition position.

[0161] In one embodiment, the acquisition configuration, preferably zoom, is automatically defined as a function of the measured distance at the service location, for example, to achieve focus.

[0162] In order to limit the surface area occupied by the representation of the spacer 24 in the field of view seen by the lens 16, it is also possible to limit the length of the spacer 24 and, instead of or in addition to adjusting the acquired configuration, in particular the zoom of the mobile phone, act on the shape of the chamber 28, in particular the shape of the spacer 24.

[0163] The chamber 28, preferably at least the spacer 24, preferably comprises at least one segment 44 that branches toward the oral cavity opening Oa, preferably regularly. In one embodiment, the branching segment 44 begins less than 5 cm, less than 3 cm, and less than 1 cm from the acquisition opening Oa', preferably less than 5 cm, less than 3 cm, and less than 1 cm from the adapter opening Oa.

[0164] Preferably, the branching segment 44 defines an acquisition opening Oa', preferably an adapter opening Oa.

[0165] Preferably, in the acquisition configuration, for example in the default configuration of the mobile phone 12, the branching segment is sufficient to be invisible to the lens 16 at the acquisition position.

[0166] To limit space requirements, the chamber 28, preferably the spacer 24, comprises at least one segment 45 that converges toward the oral opening Oa, preferably regularly. In one embodiment, the converging segment terminates less than 5 cm, less than 3 cm, or less than 1 cm from the oral opening, preferably defining the oral opening.

[0167] In one embodiment, the spacer 24 includes a branching segment 44 and a converging segment 45. Advantageously, the representation of the spacer 24 in the field of view seen by the lens 16 may be reduced, thereby facilitating focusing by the mobile phone 12.

[0168] Preferably, the spacer 24 is gray in at least the zone of the spacer 24 that is visible in the field of view seen by the lens 16.

[0169] Preferably, gray is included in the RGB (red, green, blue) code and has substantially the same value for red, green, and blue, where the maximum difference between the values ​​for red, green, and blue is preferably less than 10, preferably less than 5, and preferably substantially zero. Preferably, these values ​​are 50 to 210, preferably 70 to 190, more preferably 90 to 170, and preferably 140 to 160. For example, gray may be close to (120, 120, 120) or (150, 150, 150).

[0170] Surprisingly, the inventors discovered that the analysis of tooth color in realistic color photographs becomes easier and more efficient. Therefore, the resulting photographs are suitable for colorimetric analysis.

[0171] Without being bound by this theory, the inventors explain this result by the fact that gray is an intermediate color and does not change color during acquisition. Specifically, the settings conventionally used by the mobile phone can change the colors in a photograph, particularly by shifting the balance of white.

[0172] As shown in Figure 2, axis X 24 Length L of spacer 24 measured along 24 Preferably, it is more than 3 cm, preferably more than 4 cm, preferably more than 5 cm, and / or less than 25 cm, preferably less than 20 cm, preferably less than 15 cm, preferably less than 10 cm, preferably less than 8 cm, preferably less than 7 cm.

[0173] Spacer 24, body width 40, l 24 That is, axis X 24 The maximum dimension of the cross-section, considering all cross-sections along the line, is preferably more than 2 cm and / or less than 10 cm.

[0175] The spacer 24 preferably includes an outwardly extending distal flange 46 that is adapted to be inserted between the user's lips and teeth from the periphery of the oral opening Oa and from the outer surface of the main body 40.

[0176] Therefore, advantageously, the lip can be moved away so as not to obstruct the oral opening Oa. Furthermore, the distal flange 46 facilitates the retention of the spacer 24 in the user's oral cavity.

[0177] The distal flange 46 is preferably manufactured integrally with the body 40 of the spacer 24, thereby limiting manufacturing costs and the number of corner edges. This improves hygiene.

[0186] The distance l between the right lateral end 46d and the left lateral end 46g 46 The dimensions are preferably greater than 40 mm, more preferably greater than 50 mm, and / or preferably less than 80 mm, more preferably less than 70 mm. Advantageously, these dimensions allow the spacer to be moved laterally to the left and right of the user in the service position, as well as to bring the user's jaw to an occlusal position where the user's upper and lower teeth make contact.

[0187] Preferably, the oral opening is such that the right lateral end 46d and the left lateral end 46g are at a distance d from surface Po, as shown in Figure 16. 46 Preferably the same distance d 46 The curve is curvatured so that it moves away from the surface.

[0190] The distal flange 46 may be interrupted as in the illustrated embodiment or may include a notch in such a way as to leave the labial premolars above and below the arch over the user's arch free. The interruption or the notch also allows the spacer 24 to be moved within the user's oral cavity and, in particular, to be rotated about the dental arch in order to acquire a photograph or a 3D model in a lateral view.

[0191] The notch may have, for example, a triangular, round or rectangular shape.

[0192] The length d of the interruption or the notch 46 is preferably greater than 3 mm, greater than 5 mm, more preferably greater than 10 mm, or more preferably greater than 15 mm, and / or less than or equal to 50 mm, preferably less than 30 mm, preferably less than 20 mm (Figure 2).

[0194] As shown in Figure 11, in the transition zone 47 between the distal flange 46 and the body 40, the outer surface 49 of the spacer 24 preferably has a radius of curvature R greater than 1 mm, greater than 1.5 mm, greater than 2 mm, preferably greater than 3 mm, preferably greater than 5 mm, preferably greater than 7 mm, preferably greater than 9 mm, preferably greater than 10 mm, preferably greater than 20 mm, preferably greater than 30 mm, and / or less than 4 cm at any point (Figure 11). Thus, advantageously, the transition zone does not define any concave corner edge, whereby cleaning is facilitated and hygiene is further improved.

[0195] Preferably, as shown in FIG. 11, the thickness of the spacer wall is at least constant in the portion carrying the distal flange 46 and preferably constant over the entire length of the spacer. In particular, the chamber 28 comprises a segment 44 that branches towards the oral opening Oo, where the branching segment starts less than 5 cm from the adapter opening Oa and ends at the adapter opening Oa.

[0196] The branching segment is preferably defined by a part of the wall of the spacer having a constant thickness.

[0197] In one embodiment, the distal flange 46 is removable. In particular, the distal flange can be manufactured in the form of a dental retractor.

[0198] Preferably, the body 40, preferably the entire spacer 24, is made of an opaque material. Advantageously, the external environment does not interfere with the illumination of the teeth by the mobile phone 12. The body 40 also protects the user's privacy.

[0199] The body 40 and / or the distal flange may be made of, for example, a rigid material such as polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS), or polypropylene (PP), or a flexible material such as cardboard.

[0201] [[ID=|24]]The material is in particular a fibrous material, preferably a cellulose-based material, preferably cardboard.

[0202] The spacer may be for single use or disposable.

[0203] Preferably, the spacer 24 is a single unit. This is advantageous because it limits its manufacturing cost.

[0204] adapter

[0205] The adapter 26, particularly the adapter 26 shown in Figure 14, has the function of detachably attaching the mobile phone to the holder 14 and positioning it in an acquisition position where the lens 16 of the mobile phone 12 can see the oral cavity opening Oa through the adapter opening Oa and the acquisition opening Oa' of the spacer. Preferably, the adapter 26 is configured so that this position can be changed.

[0206] The mobile phone 12 can be attached to the adapter 26 using, for example, one or more rubber bands, one or more hook-and-loop tapes, one or more clips, one or more screws, flaps, for example, the flaps, jaws, one or more suction cups, or one or more magnets that are rotatably mounted on the base of the adapter and can be locked in a position to clamp the mobile phone 12.

[0207] The flap may be held in place on the mobile phone by any means, for example, one or more clips, one or more screws, one or more Velcro® type hook-and-loop tapes, one or more rubber bands, one or more magnets, one or more hooks, one or more bolts, one or more straps, one or more suction cups, in particular one or more micro-suction cups or one or more nano-suction cups, or adhesives, for example, gel.

[0208] The mobile phone may also be inserted into a shell, cover, or case mounted on the base of the adapter. The case may be made of, for example, plastic and may have a door that is mounted so as to be rotatable, preferably so as to be rotatable around a horizontal or vertical axis. The shape of the cover or case is not particularly limited, as long as the lens 16 can see outside the cover or case, and preferably the screen remains visible from outside the cover or case.

[0209] The case, cover, or shell may be attached to the base by any means, for example, by complementarity of shape, or by means of one or more clips, one or more screws, one or more Velcro® type hook-and-loop tapes, one or more rubber bands, one or more magnets, one or more hooks, one or more bolts, one or more straps, one or more suction cups, in particular one or more micro-suction cups or one or more nano-suction cups, or adhesives, such as gel. The case or cover may be manufactured integrally with the base.

[0210] In one embodiment, the adapter comprises a strap for attaching the mobile phone, preferably elastic, preferably made of elastomer, and preferably transparent.

[0211] This list is not exhaustive.

[0212] An "unobstructed" surface of the screen 20 is a surface that is not covered by the adapter 26. If a portion of the adapter 26, which is made of a transparent material, such as a transparent strap, covers the surface of the screen, this surface is not considered "unobstructed."

[0213] The adapter 26 is preferably configured such that, in its assembled position, it remains unobstructed over 80%, preferably over 90%, preferably over 95%, and preferably substantially 100% of the surface of the mobile phone's screen 20.

[0214] The surface of the adapter 26 that contacts the mobile phone 12 in the assembled position is referred to as the "contact surface".

[0215] Preferably, more than 70%, more preferably more than 80%, preferably more than 90%, preferably substantially 100%, of the contact surface is in contact with the front surface 121 and the side edges 22 of the mobile phone, preferably with the side edges 22 of the mobile phone.

[0216] A part of the contact surface may be in contact with the back surface of the mobile phone or may be in contact with the screen 20. Preferably, the area of this part of the contact surface represents less than 20%, preferably less than 10%, preferably less than 5%, preferably less than 2%, of the area of the back surface, and is preferably zero. Preferably, the area of this part of the contact surface represents less than 20%, preferably less than 10%, preferably less than 5%, preferably less than 2%, of the area of the screen 20.

[0217] Preferably, the contact surface does not cross the screen 20 from one edge of the back surface 122 to the opposite edge of the back surface 122. In particular, the contact surface does not cross the screen vertically. Preferably, in the assembled position, the mobile phone is not surrounded by the adapter 26, such as when a strap or flap holds the back surface and presses the mobile phone against the receiving surface of the adapter 26.

[0218] The "visible" surface of the screen 20 is a surface that is not covered by the adapter 26 or is covered by a transparent part of the adapter and thus allows the screen to be seen through it. When a part of the adapter 26 made of a transparent material, such as a transparent strap, covers the surface of the screen, this surface is considered "visible". Preferably, tactile communication with the screen is possible through the part of the adapter 26 made of a transparent material.

[0219] The "invisible" surface of the screen 20 is said to be "hidden".

[0220] The adapter 26 is preferably configured to allow more than 80%, preferably more than 90%, preferably more than 95%, and preferably substantially 100% of the surface of the mobile phone's screen 20 to be visible in the assembled position.

[0221] Advantageously, the tooth can be fully viewed from screen 20. In addition, access to the entire touch-sensitive human-machine interface is advantageous.

[0222] Preferably, the adapter 26 is configured to allow attachment of different mobile phones, particularly those having different dimensions.

[0223] In a preferred embodiment, the mobile phone 12 is held in the adapter 26 by clamping it.

[0224] Preferably, the adapter 26 comprises a base 50, a first jaw 521, and a second jaw 522 facing the first jaw, wherein at least the first jaw is mounted on the base 50 so as to be movable between a moved-together position and a spaced-apart position, where the first jaw is at the minimum and maximum distance from the second jaw, respectively.

[0225] Preferably, only the first jaw is movably mounted on the base 50. The second jaw is fixed relative to the base. This is advantageous because it simplifies and makes more compact the mechanism for locking these jaws together in place.

[0226] In a kit according to the present invention that needs to enable the use of the lens of the mobile phone located on the front of the mobile phone, saving in terms of compactness is particularly beneficial.

[0227] The stationary nature of the second jaw also allows the mobile phone to be positioned permanently before the two jaws are combined to clamp it. In particular, the operation of attaching the mobile phone is greatly simplified because it is not necessary to hold the mobile phone while the jaws are combined.

[0228] This also prevents instability.

[0229] At separated positions, the maximum distance d between the first jaw and the second jaw is 52 The length is preferably more than 5 cm, preferably more than 7 cm, preferably more than 9 cm, and / or less than 25 cm, preferably less than 15 cm (Figure 3).

[0230] At the movable connection position, the minimum distance d between the first jaw and the second jaw is 52 Preferably, it is more than 2 cm, preferably more than 3 cm, preferably more than 5 cm, and / or less than 10 cm, preferably less than 8 cm.

[0231] The movement of the first jaw toward the second jaw, i.e., an "approach movement," results in an assembly position that is roughly midway between the position where they moved together and the position where they separated, thereby allowing the first and second jaws to grip and clamp the mobile phone 12, preferably by pressing against its side edge 22.

[0232] The first jaw 521 is preferably positioned relative to the second jaw in the clamping direction Z 52 Preferably, it is installed to move vertically and translationally at the service position.

[0233] Preferably, the first jaw 521 is mounted elastically so as to be able to move translationally relative to the second jaw 522 in the clamping direction. Preferably, the adapter 26 comprises an elastically deformable member, preferably a spring 56, preferably a compression spring, which is positioned to counteract the thrust of the first jaw 521 toward the jointly moved position.

[0234] In Figure 4, the spring 56 is positioned to extend vertically within the housing of the base 50. The spring is compressed between the end wall of the housing and the first jaw 521. The adapter 26 may have multiple springs 56 positioned within each vertically extending housing, each compressed between the end wall of the housing and the first jaw 521. Advantageously, the risk of instability is reduced.

[0235] However, preferably, the adapter 26 includes a single spring 56, preferably a compression spring, extending in the clamping direction at a position midway between the width of the first jaw 521 and the width of the second jaw 522. This advantageously improves compactness.

[0236] The second jaw 522 may be movable on the base 50. However, preferably, as shown in Figure 3, the base 50 takes in the second jaw (in Figure 4, the second jaw is detached from the base 50).

[0237] As shown in Figure 4B, in the side view, at least one of the first jaw and the second jaw, preferably each of the first jaw and the second jaw, is Y 52 It has a trough shape, or "cradle shape," that extends in the direction and, in the assembled position, accepts the mobile phone 12.

[0238] Advantageously, the first jaw and the second jaw not only clamp the mobile phone but also hold it by the complementarity of their shapes. This improves the holding of the mobile phone 12. The trough shape is also in the direction Y 52 This facilitates the sliding of the mobile phone between the first jaw and the second jaw, which are parallel to the optical axis X. 16 The axis X of the adapter opening a It becomes possible to position the lens 16 so that it lies within a vertical plane that includes the lens.

[0239] Preferably, the base 50 includes a receiving surface 54 on which the mobile phone is placed in the assembled position, preferably flat and preferably vertical. This flat surface is preferably defined by an elastomer mat 58. The flat surface preferably extends to the same height as the second jaw. Advantageously, the placement of the mobile phone on the receiving surface 54 contributes to holding the mobile phone, particularly by limiting slippage between the first jaw and the second jaw.

[0240] Preferably, the movement of the mobile phone 12 placed between the first jaw and the second jaw is not restricted by any stop, thereby allowing a mobile phone of any length to be placed in a predetermined position.

[0241] Preferably, at least the first jaw 521 is mounted on the base 50 so as to be incrementally movable.

[0242] Preferably, the adapter 26 includes a first releasable anti-return system that prevents the separation movement of the first jaw, i.e., movement in the opposite direction to the approach movement. The first anti-return system is preferably as shown in Figures 4 and 5, A first pawl 62, where the first pawl 62 is mounted on the base 50 so as to be releasable along axis X 62 It is mounted so that it can rotate around it. Ratchet wheel 64, where the ratchet wheel 64 is mounted on the base 50, axis X 64 The first jaw 521 is mounted to interact with the first jaw 62 so as to be rotatable around the ratchet wheel 64, and the rotation of the ratchet wheel 64 causes the first jaw 521 to clamp in the Z direction. 52 Mechanically connected to the first jaw so as to move parallel to it, A first spring 66, which elastically presses the first pawl 62 against the teeth of the ratchet wheel 64 so that the rotation of the ratchet wheel 64 rotates only in the rotational direction that results in an approach motion. It is equipped with.

[0243] Clamping direction Z 52 The continuous position of the first jaw during translational motion is referred to as the "indexed position" and is marked by the elastic penetration of the first pawl 62 between the continuous teeth of the ratchet wheel 64.

[0244] The connection between the ratchet wheel 64 and the first jaw 521 can be reliably achieved by the rack and pinion assembly.

[0245] Preferably, the first jaw 521 is provided with a first rack 68 extending parallel to the clamping direction, and the adapter 26 is mounted on the base 50 along axis X 64 It is equipped with a stepped wheel 70 that is rotatably mounted around it, and the stepped wheel 70 is Ratchet wheel 64, and, A pinion 72 positioned coaxially with a ratchet wheel 64, wherein the rotation of the pinion 72 interacts with the first rack 68 such that the rotation of the pinion 72 moves the first jaw parallel to the clamping direction. It is equipped with.

[0246] Advantageously, such stepped wheels are particularly compact, allowing for gradual and well-controlled movement of the first jaw.

[0247] The adapter 26 preferably includes a first push button 74, which, when pressed, releases the first locking mechanism.

[0248] Preferably, the first pawl 62 is connected to the first push button 74 such that when the push button is operated (by pressing the push button), the first pawl 62 disengages from the ratchet wheel. In the preferred embodiment shown in Figure 4, the first push button 74 and the first pawl 62 are each connected to axis X 62 It is located at one end of a rocker 76 that is rotatably mounted around the ratchet wheel 64. Therefore, by pressing the first push button 74, the rocker 76 rotates and the first pawl 62 disengages from the teeth of the ratchet wheel 64, i.e., the first locking mechanism is released. When the button is released, the rocker 76 rotates in the opposite direction due to the action of the first spring 66 and the first pawl 62 engages with the teeth of the ratchet wheel 64.

[0249] Accordingly, the first locking system selectively locks the position of the first jaw 521 on the base 50 or forms a lock to allow movement of the first jaw 521.

[0250] As described above, preferably, the first jaw 521 is mounted on the base 50 so as to be movable so as to be elastically separated from the second jaw. Therefore, the deactivation of the first retaining system results in an elastic return to the separated position.

[0251] Advantageously, the elastic return of the first jaw 521 to its separated position makes mounting the mobile phone 12 onto the adapter 26 considerably easier.

[0252] Preferably, at least one of the first jaw and the second jaw, preferably each of the first jaw and the second jaw, is equipped with an elastomer pad 78, which is supported on the mobile phone 12 in the assembled position.

[0253] Preferably, the pad 78 is configured such that the first jaw is incrementally movable on the base 50 and that the elastic deformation of the pad allows it to reach the next indexed position when the pad 78 begins to clamp the mobile phone. Advantageously, by clamping the mobile phone, it is possible to clamp it effectively without damaging it. The pad 78 also helps to protect the mobile phone from shocks and vibrations.

[0254] Preferably, the clamping zone 71 in which the mobile phone 12 is clamped by the first jaw and the second jaw is exclusively defined by the pad 78.

[0255] The clamp zone 71 consists of a set of clamp points. At each of these points, the adapter applies a compressive force to the mobile phone 12, referred to as the “clamp” force. The maximum distance between the clamp points, measured in the direction of the length L2 of the mobile phone, is preferably more than 1 cm, preferably more than 2 cm, more than 3 cm, and / or less than 20 cm, preferably less than 10 cm, preferably less than 8 cm, preferably less than 6 cm, and preferably less than 5 cm.

[0256] Preferably, at least one "basic" clamp zone (i.e., the portion of the clamp zone defined by the jaws), preferably each basic clamp zone, has a total length L of more than 1 cm, preferably more than 2 cm, more than 3 cm, and / or less than 20 cm, preferably less than 10 cm, preferably less than 8 cm, preferably less than 6 cm, preferably less than 5 cm. 52 It has. "Total length" refers to the distance between two points in the basic clamping zone, in the direction Y 52means the maximum distance in. In particular, when the basic clamping zone is locally interrupted between these two points, the overall length does not change.

[0257] In the embodiment shown in FIG. 4, the overall length L 52 is the maximum distance between a plurality of clamping points.

[0258] Advantageously, the attachment of the mobile phone 12 to the adapter 26 is particularly stable. Accordingly, the kit may be handled by holding the mobile phone, thereby facilitating the acquisition of data through the lens 16 of the mobile phone.

[0259] The basic clamping zone of the first jaw and / or the second jaw preferably extends in the longitudinal direction of the mobile phone.

[0260] Preferably, as shown in FIG. 6, the adapter 26 further includes a plate 80, the plate 80 defining an adapter opening Oa and being movably mounted on the base 50, preferably at least in the translational direction, preferably parallel to the vertical slide direction Z 80 parallel to, preferably exclusively parallel to, the slide direction Z 80 and is movably mounted.

[0261] The slide can be achieved by a slider slidably mounted on a rail formed in the base 50, for example a slider carried by the plate 80. Sliding by means of a plurality of sliders slidably mounted on respective parallel rails can achieve limiting the risk of instability.

[0262] Therefore, advantageously, the position of the adapter opening Oa relative to the lens 16 can be changed.

[0263] Preferably, the ability of the plate 80 to move on the base 50 is independent of the ability of the first jaw to move on the base 50, and more generally, independent of the position of the mobile phone 12 on the adapter 26.

[0264] The mobile phone 12 is rigidly attached to the plate 80 by being removably clamped between the first jaw and the second jaw.

[0265] Therefore, the position of the mobile phone 12 relative to the adapter opening Oa can be independently adjusted horizontally by sliding the first jaw and the second jaw, and vertically by sliding the plate 80 on the base 50, until the lens 16 is positioned opposite the adapter opening Oa, preferably substantially in the center of the adapter opening Oa.

[0266] The adapter aperture Oa is preferably sized such that, at least at the center of the lens 16, the flash 18 faces the adapter aperture Oa. Advantageously, the flash 18 can illuminate the teeth while the mobile phone 12 acquires 2D or 3D data.

[0267] The plate 80 is preferably mounted on the base 50 so as to be incrementally movable. In other words, it can be moved incrementally, preferably by a constant increment, in at least one direction. This advantageously facilitates adjustment of the position of the adapter opening Oa relative to the mobile phone.

[0268] Preferably, the adapter 26 is provided with a releaseable lock for selectively locking the plate 80 in a position relative to the base 50.

[0269] Preferably, the base 50 comprises a second rack 82, and the plate 80 is Axis X on plate 80 so as to interact with the teeth of the second rack 82 84 A second claw 84 is mounted to rotate around it, A second spring 86 elastically presses the second claw 84 against the teeth of the second rack 82 to define an indexed position for positioning the plate 80 along the second rack 82. The system is equipped with these features. These consecutive indexed positions are marked by the elastic penetration of the second claw 84 between consecutive teeth of the second rack 82.

[0270] Preferably, the second rack 82 and the second claw 84 are shaped so that the plate 80 can translate in only one direction, i.e., only upward in Figures 6 and 7.

[0271] Accordingly, the second rack 82 and the second claw 84 define a releasable second anti-return system that prevents the plate 80 from moving back (in this case, downward) relative to the base 50.

[0272] The adapter 26 preferably includes a second push button 94, which, when pressed, stops the operation of the second return stop system.

[0273] Preferably, the second claw 84 is connected to the second push button 94 such that, by operation (by pressing the second push button 94), the second claw 84 is released from the second rack 82. In the preferred embodiment shown in Figures 6 and 7, the second push button 94 and the second claw 84 are each connected to axis X 84 It is located at one end of a rocker 96 that is rotatably mounted around the second rack 82. Therefore, by pressing the second push button 94, the rocker 96 rotates and the second pawl 84 disengages from the teeth of the second rack 82, that is, the second locking system is released. When the button is released, this causes it to rotate in the opposite direction by the action of the second spring 86 and the second pawl 84 engages with the teeth of the second rack 82.

[0274] Accordingly, the second anti-return system forms a lock for selectively locking or allowing movement of the plate 80 on the base 50.

[0275] Of course, in an equivalent configuration, the second rack 82 can be mounted on the plate 80 and the second claw 84 on the base 50.

[0276] In a preferred embodiment, reference marks made on the adapter indicate possible positions of the mobile phone 12 relative to the base 50 and / or possible positions of the plate 80 relative to the base 50, depending, for example, on the type or brand of the mobile phone. The reference marks may be, for example, arrows associated with the brand of the mobile phone.

[0277] Preferably, the plate 80 has a first reference mark and the base has more than one second reference mark on the opposite side on which the first reference mark may be located, or equivalently, the base 50 has a first reference mark and the plate 80 has more than one second reference mark on the opposite side on which the first reference mark may be located. Preferably, the second reference mark corresponds to the brand of the mobile phone. In other words, in order to properly position the mobile phone in the holder, it is necessary to position the first reference mark opposite to the second reference mark corresponding to the brand of the mobile phone.

[0278] Preferably, as shown in Figure 6B, the acquisition opening Oa' is offset laterally with respect to the clamping zone into which the mobile phone 12 is clamped to the adapter 26.

[0279] The lateral offset is determined by viewing the adapter 26 from the front, i.e., parallel to the axis of the acquisition opening Oa' (Figure 6B). In Figure 6B, vertical planes P1 and P2 demarcate the clamping zone.

[0280] The offset direction Y is horizontal and parallel to the front surface of the mobile phone.

[0281] In the offset direction Y, the positions p of the center Ca' of the acquired opening Oa' and the center Cs of the clamping zone are respectively.a’ and p s can be identified. The horizontal offset is the distance d in the offset direction Y l measured thereby (FIG. 6B).

[0282] Preferably, the horizontal offset is constant.

[0283] Preferably, the horizontal offset is more than 1 cm, preferably more than 1 cm, preferably more than 3 cm, or even more preferably more than 4 cm, or more than 5 cm, and / or less than 10 cm.

[0284] Advantageously, the horizontal offset allows the acquisition aperture Oa' to be arranged facing the lens 16, and even when the lens 16 is very close to the edge of the front surface, enables the mobile phone to be firmly attached to the adapter 26. This attachment is particularly effective because the clamping zone can be substantially halved along the length of the mobile phone 12 while the acquisition aperture or the adapter aperture is close to the side edge of the mobile phone 12.

[0285] In one embodiment, the mobile phone is clamped via its two large side surfaces as shown in FIG. 6 and held horizontally for acquisition of an image or 3D model. In this preferred embodiment, the horizontal offset not only balances the kit, but is preferably clamped at a position substantially half along the length, and also facilitates access to the buttons of the mobile phone in the region of the lens 16, i.e., at the top of the mobile phone, in the longitudinal direction of the mobile phone.

[0286] operation

[0287] The method of operating the kit is directly derived from the previous description.

[0288] Initially, the kit is in its disassembled position. If applicable, the user selects spacer 24 from among several spacers according to the personalization mark 39.

[0289] The user clips the spacer 24 onto the adapter 26 and inserts the end of the spacer 24 opposite to the oral opening Oa into the housing, which has a complementary shape defined by the adapter.

[0290] Clipping is achieved by hooking the claws of the adapter into recesses formed on the outer surface of the spacer 24.

[0291] After clipping, the spacer substantially extends to the adapter opening Oa defined by the housing. Thus, when the spacer is in the service position, it defines the lining that limits contact between the walls defining the housing and the breathing air.

[0292] If the first jaw and the second jaw are too close to each other to place the mobile phone in a predetermined position, the user presses the first push button 74 to disengage the first pawl 62 from the ratchet wheel 64. Under the action of the compression spring 56, the first jaw 521 moves away from the second jaw and reaches a separated position. The user then stops pressing the first push button 74.

[0293] The distance d between the first jaw and the second jaw 52 The width of the mobile phone 12 is greater than the width of the mobile phone 12. The user then places the mobile phone 12 on the mat 58 and rests it on the second jaw 522, and then moves it laterally along the second jaw until the adapter opening Oa is substantially aligned with the lens 16, i.e., above or below the lens 16. The lateral offset of the first and second jaws relative to the adapter opening makes it possible to achieve this position without substantially shifting the clamp from the center of the mobile phone's length.

[0294] Next, the user pushes the first jaw back until it contacts the side of the mobile phone, and then grips the mobile phone with the second jaw.

[0295] Therefore, as the jaws move toward each other, the first rack 68 drives the pinion 72, and thus drives the stepped wheel 70 and the ratchet wheel 64. The first pawl 62, pushed by the first spring 66, engages with the ratchet wheel 64 and prevents any movement of the first jaw and the second jaw apart. The first pawl 62 also enables incremental movement of the first jaw, in other words, movement "in increments".

[0296] When the first jaw contacts the side of the mobile phone, the action of the mobile phone prevents the approach motion from continuing. However, deformation of the pad 78 allows the first jaw to be pushed at least to the next notch (where the first pawl 62 engages with the next tooth on the ratchet wheel).

[0297] Therefore, the mobile phone 12 is rigidly attached to the base 50 and clamped between the first jaw and the second jaw. The screen 20 is not obstructed at all.

[0298] Next, the user adjusts the vertical position of the plate 80 on the base 50 so that the adapter opening substantially faces the lens 16.

[0299] In the embodiments shown in Figures 6 and 7, the second claw 84, pushed by the second spring 86, engages with the teeth of the second rack 82, thereby preventing the plate 80 from moving downward. This allows for incremental movement of the plate 80.

[0300] If the plate 80 is too high, the user presses the second push button 94 to disengage the second claw 84 from the second rack 82. The user can then lower the plate 80. As soon as the user releases the second push button 94, the claw re-engages with the second rack 82 under the action of the second spring 86.

[0301] Once the adapter opening Oa is substantially facing the lens 16, preferably the flash, the kit in the acquisition position is ready for use.

[0302] Next, the user activates the mobile phone so that it can be used to acquire an image or a 3D model. Since the screen 20 is not completely obscured, the user can use the screen 20 to their advantage.

[0303] Next, the user inserts the distal flange 46 between the lip and the tooth, positioning the oral opening toward the tooth from which data is to be acquired, preferably photographed, or scanned. Thus, the user is in a service position. The user acquires this data by pressing the shutter button on the mobile phone.

[0304] Next, the user moves the oral opening to obtain data about other teeth.

[0305] The spacer does not prevent the user's jaw from moving closer or further away. Therefore, the spacer makes it possible to take photographs, in particular, of the user's teeth with their mouth open or closed, while keeping their lips pushed back.

[0306] By rotating the kit around themselves, the user can enable the mobile phone to examine various areas of the user's mouth, for example, taking pictures of the dental arch or the teeth at the back of the mouth.

[0307] Preferably, the user acquires 2D or 3D data in at least the front view, right side view, and left side view. Preferably, the user acquires 2D or 3D data each time in at least one open view and at least one closed view, preferably in the front view, right-hand view, and left-hand view.

[0308] Next, the user removes the spacer 24 from the opening and then removes the mobile phone. To do this, the first push button 74 is pressed to disengage the first pawl 62 from the ratchet wheel 64. Under the action of the spring 56, the first jaw 521 separates from the second jaw and reaches a separated position, allowing the mobile phone 12 to be removed.

[0309] Next, the user may use the mobile phone 12 to analyze the acquired data and / or transmit the acquired data.

[0310] Finally, the user separates the spacer 24 from the adapter 26 by pulling the spacer firmly to disengage the claw 38.

[0311] Generally, only the spacer needs to be cleaned or sterilized. Advantageously, the spacer does not have any moving parts whose operation could be affected by these operations.

[0312] The spacer also does not have any concave corner edges that can easily trap dirt. Therefore, cleaning or sterilization can be performed more effectively.

[0313] Naturally, the order of operations can be changed. For example, the spacer may be attached to the adapter before or after attaching the mobile phone. The spacer may be removed before or after attaching the mobile phone.

[0314] As is evident here, the present invention significantly facilitates the acquisition of photographs or 3D models, including those showing the vestibular surface of a molar, particularly for carrying out the method described in International Patent Application No. PCT / EP2015 / 074896. These can be acquired quickly, typically in less than one minute, under highly hygienic conditions, without the need for a specialist, especially a dentist or orthodontist. In particular, the acquisition can be performed anywhere, without visiting a medical, dental, or orthodontic clinic, simply by the user themselves or a friend or relative using the mobile phone. Furthermore, acquisition is possible without using any tools to hold the mobile phone on the ground, especially without using a tripod.

[0315] Finally, this kit allows for quick and secure attachment to any phone, regardless of its thickness, without damaging the phone.

[0316] Naturally, the present invention is not limited to the embodiments described and illustrated, which are provided purely for illustrative purposes.

[0317] In particular, the shape of the spacer is not limited.

[0318] The second jaw may be movable and may optionally be mounted on the base in the same manner as the first jaw.

[0319] In one embodiment, the first jaw 521 is mounted movably on the base 50 so as to elastically approach the second jaw. The first anti-return system may then be designed to prevent this approach, and its deactivation causes an elastic return to the position from which they moved together.
