DENTAL STABILIZATION BLOCKS, SYSTEMS AND METHODS

Abstract

One of the objectives of this invention is to provide a dental stabilization device that prevents a patient from easily loosening their teeth during a dental procedure. To this end, the inventor proposes a dental stabilization block comprising internal channels that open onto the faces of the block which come into contact with the patient's teeth. These internal channels are connected to an inlet through which an occlusal registration material can be injected. This material is designed to harden and mold to the patient's teeth. In this way, once the occlusal registration material has hardened and molded around the teeth, it becomes more difficult for the patient to loosen their teeth from the dental stabilization block.

[0031] [Fig. 10] The [Fig. 10] represents a method according to the invention. Description of the implementation methods

[0032] One of the objectives of this invention is to provide a dental stabilization device which prevents a patient, during a dental procedure, from easily loosening their teeth.

[0033] To this end, the inventor proposes a dental stabilization block comprising internal channels that open onto the faces of the dental stabilization block that come into contact with the patient's teeth. These internal channels are connected to an inlet through which an occlusal recording material can be injected, which is intended to harden and be molded onto the patient's teeth.

[0034] In this way, when the occlusion recording material has hardened and molded itself around the teeth, it becomes more difficult for the patient to loosen his teeth from the dental stabilization block.

[0035] Thus, as illustrated in [Fig.1], the invention relates to a dental stabilization block 100.

[0036] In practice, the dental stabilization block 100 is intended to be bitten, on one side of the mouth only, between the upper and lower molars and / or premolars of a patient, hereinafter referred to as "teeth".

[0037] In other words, when the dental stabilization block 100 is in place in the patient's mouth, the patient can bite down on the dental stabilization block 100, either only with his upper and lower molars, or only with his upper and lower premolars, or both with his upper and lower molars and upper and lower premolars.

[0038] In a preferred embodiment of the invention, different sizes of the dental stabilization block 100 can be provided depending on the dental morphology of the patient, namely the arrangement of his teeth on the upper jaw and on the lower jaw.

[0039] For example, one could provide a model for children and a model for adults.

[0040] However, depending on the needs, other arrangements for taking into account the dental morphology of patients may be considered, without requiring modifications substantial parts of the invention.

[0041] Fig. 2 illustrates the dental stabilization block 100 when positioned on lower teeth located on the left side of the patient's mouth.

[0042] In practice, the dental stabilization block 100 allows the patient's mouth to be kept open during a dental procedure so as to prevent the teeth from meeting.

[0043] Thus, the dental stabilization block 100 allows access to teeth and gums located on the opposite side of the mouth and at the front of the mouth, without being significantly hindered by the dental stabilization block 100.

[0044] In other words, when the dental stabilization block 100 is in place in the patient's mouth, the practitioner performing the dental procedure can access, inside the mouth, the teeth and gums located in the front part of the mouth as well as the part of the mouth located opposite the position of the dental stabilization block 100.

[0045] Thus, in a first example, if the dental stabilization block 100 is positioned on teeth located on the right side of the patient's mouth, then the practitioner can access the teeth and gums which are located at the front of the mouth as well as those which are located on the left side of the mouth.

[0046] Similarly, in a second example, if the dental stabilization block 100 is positioned on teeth located on the left side of the patient's mouth, then the practitioner can access the teeth and gums which are located at the front of the mouth as well as those which are located on the right side of the mouth.

[0047] Returning to the invention, the dental stabilization block 100 comprises a body 110 which is essentially parallelepiped in shape.

[0048] Thus, the body 110 has a parallelepiped shape, namely, the shape of a six-sided polyhedron whose six faces are parallel in pairs.

[0049] In practice, the shape of the body 110 is substantially curved to take into account the approximate curve of the upper and lower teeth in a human jaw.

[0050] In particular, as illustrated in [Fig.1], [Fig.3], [Fig.7] and [Fig.9], when the dental stabilization block 100 is in place in the patient's mouth, the body 110 comprises an upper wall 111, an lower wall 112, a first lateral wall 113, a second lateral wall 114, an anterior end wall 115 and a posterior end wall 116.

[0051] In practice, the upper wall 111 has an upper external clamping surface which is designed to come into contact with the upper teeth.

[0052] In a particular embodiment of the upper external clamping surface, as illustrated in [Fig. 1], [Fig. 3], [Fig. 4], [Fig. 5], [Fig. 6], [Fig. 7] and the [Fig.9], the upper external clamping surface includes an upper peripheral rim 1111.

[0053] In particular, the upper peripheral rim 1111 is configured to retain an occlusion recording material as described below.

[0054] In a particular embodiment of the upper external clamping surface, as illustrated in [Fig.1], [Fig.3], [Fig.4], [Fig.5], [Fig.6], [Fig.7] and [Fig.9], it is provided with a plurality of fluid flow disturbance ribs 1112.

[0055] In practice, each fluid flow disturbance rib 1112 is configured to cause a disturbance in the flow of a fluid flowing over the upper external clamping surface.

[0056] In a first example of this particular implementation, the fluid flow disturbance ribs 1112 extend upwards from the upper external clamping surface.

[0057] In a second example of this particular implementation, the fluid flow disturbance ribs 1112 extend through a fluid flow axis of the upper external clamping surface.

[0058] In a third example of this particular implementation, the fluid flow disturbance ribs 1112 have an upper outer turbulence surface which is selected from: a stepped surface, a striated surface, a honeycomb surface or a rough surface.

[0059] In addition, as illustrated in [Fig.1], [Fig.3], [Fig.4] and [Fig.5], the upper external clamping surface includes at least one first outlet orifice 1113.

[0060] In a particular embodiment of the first outlet orifice 1113, as illustrated in [Fig.4], the first outlet orifice 1113 includes a peripheral internal recess 1113a so as to form at least one first peripheral recess surface which is arranged below the upper external clamping surface.

[0061] Similar to the upper wall 111, the lower wall 112 has a lower external clamping surface which is designed to come into contact with the lower teeth.

[0062] In a particular embodiment of the lower external clamping surface, the latter is provided with a plurality of fluid flow disturbance ribs which are similar to the fluid flow disturbance ribs 1112 of the upper external clamping surface.

[0063] In a first example of this particular implementation, the fluid flow disturbance ribs extend upwards from the upper external clamping surface.

[0064] In a second example of this particular implementation, the fluid flow disturbance ribs extend through a fluid flow axis the upper external clamping surface.

[0065] In a third example of this particular implementation, the fluid flow disturbance ribs have an upper outer turbulence surface which is chosen from: a stepped surface, a striated surface, a honeycomb surface or a rough surface.

[0066] In addition, the lower external clamping surface includes at least one second outlet 1123.

[0067] Similar to the first outlet orifice 1113, in a particular embodiment of the second outlet orifice 1123, the latter includes a peripheral internal recess so as to form at least one second peripheral recess surface which is arranged below the lower external clamping surface.

[0068] As illustrated in [Fig.2], in conjunction with [Fig.1], [Fig.3], [Fig.4], [Fig.5], [Fig.6], [Fig.7] and [Fig.9], when the dental stabilization block 100 is in place in the patient's mouth: - the first lateral wall 113 is oriented towards the inside of the mouth, - The second lateral wall 114 is oriented towards an inner cheek surface, specifically the inner cheek surface on the side of the mouth where the dental stabilization block 100 is installed. Thus, if the dental stabilization block 100 is installed on the right side of the patient's mouth, then the second lateral wall 114 is oriented towards the inner surface of the patient's right cheek. Conversely, if the dental stabilization block 100 is installed on the left side of the patient's mouth, then the second lateral wall 114 is oriented towards the inner surface of the patient's left cheek. - the front end wall 115 is oriented towards the front of the mouth, and - the rear end wall 116 is oriented towards the rear of the mouth.

[0069] In addition, as illustrated in [Fig.5], the body 110 comprises at least a first internal channel 117, at least a second internal channel 118 and a first internal junction region 119.

[0070] In particular, the first internal channel 117, which is located inside the body 110, opens to the outside of the body 110 at the level of at least one first outlet orifice 1113 and / or at least one second outlet orifice 1123.

[0071] In other words, the first internal channel 117 can be opened to the outside, either by passing only through the first outlet orifice 1113, or by passing only through the second outlet orifice 1123, or by passing through both the first outlet orifice 1113 and the second outlet orifice 1123.

[0072] Furthermore, the first internal channel 117 defines a flow path which is configured to be traversed by an occlusion recording material intended to harden and be molded at least onto the teeth.

[0073] In a first implementation of the occlusion recording material, it is chosen from waxes.

[0074] For example, one may choose from mineral waxes (e.g. alkanes such as Paraffins), waxes of natural origin (e.g. esters such as Camauba wax, beeswax), waxes of synthetic origin (e.g. polyethylene wax, polyethylene glycol wax, hydrogenated or halogenated hydrocarbon waxes) and all combinations thereof.

[0075] In a second implementation of the occlusion recording material, it is chosen from zinc oxide-eugenol pastes.

[0076] In a third embodiment of the occlusion recording material, it is selected from addition silicone elastomers

[0077] In a fourth implementation of the occlusion recording material, it is chosen from polyester elastomers.

[0078] However, depending on the needs, it may be possible to consider using other dental materials which are capable of deforming under occlusal stress, recording this deformation and restoring it without modifications, without requiring substantial modifications to the invention.

[0079] The second internal channel 118, which is located inside the body 110, opens to the outside of the body 110 at an inlet orifice 1131.

[0080] The inlet port 1131 is configured to receive at least one end portion of an occlusion recording material injection device.

[0081] In one example, the end portion according to the invention is a mixing tip of a known type occlusion recording injector.

[0082] In a particular embodiment of the inlet orifice 1131, as illustrated in [Fig.5] and [Fig.8], the inlet orifice 1131 includes a shoulder 1132 against which the end of the occlusion recording material injection device can butt.

[0083] Furthermore, in the invention, the inlet orifice 1131 is disposed on an external surface of the first side wall 113 and / or the front end wall 115.

[0084] In other words, the inlet orifice 1131 can be located either only on an external surface of the first side wall 113, or only on an external surface of the front end wall 115, or both on an external surface of the first side wall 113 and on an external surface of the front end wall 115.

[0085] Finally, the first internal junction region 119 is configured to establish fluidic communication between the first internal channel 117 and the second channel internal 118.

[0086] Thus, when the occlusion recording material is injected into the inlet port 1131, the occlusion recording material can exit at the outlet ports 1113, 1123.

[0087] Fig. 5 illustrates the outlet ports 1113, 1123.

[0088] In a first embodiment of the invention, the body 110 comprises a plurality of first internal channels 117 and a plurality of second internal junction regions.

[0089] In practice, the plurality of first internal channels 117, which are located inside the body 110, is arranged so that, in response to the injection of the occlusion recording material, the occlusion recording material arrives substantially at the same time at the exit ports 1113, 1123.

[0090] In addition, the plurality of second internal junction regions is arranged so that each second internal junction region establishes fluidic communication between at least two first internal channels 117.

[0091] In other words, each second internal junction region can establish a fluidic connection between two, three, four or more of the first four internal channels 117.

[0092] In a second embodiment of the invention, the first side wall 113 and the second side wall 114 are designed to extend upwards and / or downwards from the mouth beyond the upper external clamping surface and / or the lower external clamping surface.

[0093] Put another way, in the second embodiment of the invention, the first side wall 113 and the second side wall 114 extend either only towards the top of the mouth, or only towards the bottom of the mouth, or both up and down the mouth.

[0094] This arrangement is such that, when the dental stabilization block 100 is in place in the patient's mouth, it allows the upper and / or lower teeth to be covered so as to form an upper and / or lower enclosure with a U-shaped cross-section in which the occlusion recording material and the upper and / or lower teeth can be retained.

[0095] In other words, when the first side wall 113 and the second side wall 114 extend only upwards from the mouth, they form the upper enclosure. Furthermore, when the first side wall 113 and the second side wall 114 extend only downwards from the mouth, they form the lower enclosure. Finally, when the first side wall 113 and the second side wall 114 extend both upwards and downwards from the mouth, they form the upper and lower enclosures.

[0096] In particular, as illustrated in [Fig.6], in the upper enclosure 1114 and in the lower enclosure, the base of the U-shaped section of the upper enclosure 1114 or of the lower enclosure contains, respectively, the upper external clamping surface or the lower external clamping surface.

[0097] In addition, the wings of the U-shaped section of the upper enclosure 1114 or of the lower enclosure contain, respectively, the first side wall 113 and the second side wall 114.

[0098] Thus, the upper enclosure 1114 has a U-shaped section, the base of which contains the upper external clamping surface and the wings of which contain the first side wall 113 and the second side wall 114.

[0099] Furthermore, similarly to the upper enclosure 1114, the lower enclosure has a U-shaped section, the base of which contains the lower external clamping surface and the wings of which contain the first side wall 113 and the second side wall 114.

[0100] In a particular embodiment, as illustrated in [Fig.1], [Fig.3], [Fig.4] and [Fig.6], the second side wall 114 extends higher than the first side wall 113.

[0101] In a third embodiment of the invention, the second side wall 114 is provided with a part of a flared spreader 130 which is intended to spread apart the inner cheek face of the second side wall 114.

[0102] In particular, as illustrated in [Fig.1], [Fig.2], [Fig.3], [Fig.6], [Fig.7], [Fig.8] and [Fig.9], the cheek retractor part 130 projects from the second lateral wall 114 towards the inner face of the cheek.

[0103] Furthermore, as illustrated in [Fig.7] and [Fig.9], when the dental stabilization block 100 is in place in the patient's mouth, the foiled retractor portion 130 has an L-shape with a rounded elbow 131.

[0104] In practice, as illustrated in [Fig.7] and [Fig.9], one of the arms of the part of the outstretched spreader 130, hereinafter referred to as the "support arm" 132 and the rounded elbow 131 bear on the inner face of the cheek.

[0105] Furthermore, the other branch of the cheek spreader part 130, hereinafter referred to as the "cantilever branch" 133, is cantilevered and rests, at least in part, on the second lateral wall 114.

[0106] In a first embodiment of the third way of carrying out the invention, as illustrated in [Fig.8], the foiled spreader part 130 includes at least a third internal channel 134 which is arranged, at least in part, inside the rounded elbow 131.

[0107] In a first embodiment of the first embodiment of the third embodiment of the invention, the internal channel 134 is arranged inside the elbow rounded 131 and inside the support arm 132.

[0108] In a second embodiment of the first embodiment of the third way of carrying out the invention, the internal channel 134 is arranged inside the rounded elbow 131 and inside the cantilevered branch 133.

[0109] In a third embodiment of the first embodiment of the third way of carrying out the invention, the internal channel 134 is arranged inside the rounded elbow 131, inside the support arm 132 and inside the cantilever arm 133.

[0110] In practice, the third internal channel 134 opens to the outside of the body of the support branch 132 at the level of a suction port 1341 and at the level of an evacuation port 1342.

[0111] In particular, as illustrated in [Fig.8], the suction port 1341 is disposed on the cantilevered branch 133 upstream of the rear end wall 116 relative to the patient's mouth.

[0112] Furthermore, the evacuation orifice 1342 is disposed on the support arm 132 downstream of the suction orifice 1341 relative to the patient's mouth.

[0113] In a particular embodiment of the first embodiment of the third way of carrying out the invention, as illustrated in [Fig.8], the support arm 132 includes a suction cannula guide portion 1321 which is open towards the second side wall 114 and which extends axially from the discharge port 1342 to the free end of the support arm 132.

[0114] In a second embodiment of the third way of carrying out the invention, as illustrated in [Fig.9], the dental stabilization block 100 further comprises an extension arm 140 which extends obliquely or perpendicularly from the free end of the support arm 132 outwards from the mouth.

[0115] In practice, the extension arm 140 is designed to form a change of direction region 141 which, when the extension arm 140 deviates to exit the patient's mouth, presents an outer surface which covers the labial commissure of the mouth.

[0116] Furthermore, at least one free end region of the extension branch 140 includes at least one support element 142, 143 which is adapted to support at least one position reference element.

[0117] In the invention, the position reference element is designed to serve as a guiding element of a known type of dental surgery navigation system.

[0118] The term "dental surgery navigation system" means a computer-assisted navigation system that provides visual assistance to a practitioner during a dental procedure. Several guidance technologies exist (e.g., fluoroscopy, optical, or electromagnetic), but the goal remains the same: knowledge of how to provide, using medical imaging, an accurate feedback on the position of the dental stabilization block 100.

[0119] In practice, the position reference element is adapted so that, when the position reference element is moved in response to at least one movement of the patient's head, it triggers a re-registration of one or more dental images associated with the patient, depending on the movement of the patient's head.

[0120] The invention also covers a first dental stabilization system.

[0121] In practice, the first dental stabilization system comprises the dental stabilization block 100 according to the second embodiment of the third way of carrying out the invention and a position reference element as described above.

[0122] In particular, the position reference element is configured to be coupled to at least one support element 142, 143 of the free end region of the extension branch 140.

[0123] The invention also covers a second dental stabilization system.

[0124] In practice, the second dental stabilization system comprises two dental stabilization blocks 100 according to any one of the variants of the invention.

[0125] In particular, the two dental stabilization blocks 100 of the second dental stabilization system are configured to be positioned on opposite sides of the patient's mouth.

[0126] Finally, as illustrated in [Fig.10], the invention covers a method 200 for dental stabilization of the upper and lower molars and / or premolars of a patient, hereinafter referred to as "teeth", during a dental procedure.

[0127] First, the method 200 includes an installation step 210, in the patient's mouth, of at least one dental stabilization block 100 according to any one of the variants of the invention.

[0128] Next, the method 200 includes a step of introducing an end portion of an injection device of an occlusion recording material to the inlet orifice 1131, the occlusion recording material being intended to harden and be molded at least onto the teeth.

[0129] Finally, the method 200 includes an injection step 230 of the occlusion recording material into the inlet orifice 1131.
