[0039] Figure 1 A packaging device 1 for a dental restoration according to an embodiment of the present invention is shown. The packaging device 1 is intended to protect the dental restoration between its manufacture and its use by a dentist. The packaging device 1 is a unitary packaging device, that is, it is intended to enclose a single dental restoration. As a variant, the packaging device can accommodate multiple dental restorations. In particular, the dental restoration is a dental implant. The dental implant is intended to be screwed into the patient's bone structure. Due to its integration into the patient's bone, the dental implant requires a packaging device to provide optimal protection to prevent any risk of contamination. Therefore, the packaging device is intended to seal or quasi-seal the dental restoration, in particular so as to prevent direct contact between the dental restoration and the user's fingers. As a variant, the dental restoration may be different from a dental implant, such as a dental abutment, a crown or a bridge.

[0040] The packaging device 1 comprises a base 2 comprising a support 3 intended to hold a dental restoration, a capsule 4 formed by a first portion 5 and a second portion 6. The first arm 7 extends between the base 2 and the first portion 5 of the capsule 4. Similarly, the second arm 8 extends between the base 2 and the second portion 6 of the capsule 4. Thus, the first arm 7 comprises a first end 7A connected to the base 2, and a second end 7B opposite the first end 7A and connected to the first portion 5 of the capsule 4. Similarly, the second arm 8 comprises a first end 8A connected to the base 2, and a second end 8B opposite the first end 8A and connected to the second portion 6 of the capsule 4. Thus, the two portions 5 and 6 of the capsule are connected to the base 2 by the two arms 7 and 8, respectively.

[0041] exist Figure 1 In the embodiment, the packaging device is shown in its original configuration, that is, the packaging device is in its manufactured state without deformation. The packaging device can be transformed from its original configuration to a closed configuration ( Figure 2 In the closed configuration, the first part 5 and the second part 6 of the shell 4 are brought close to each other to enclose the dental restoration. In particular, the two parts 5 and 6 are in contact with each other along the contact line. In the open configuration ( Figure 8), the first part 5 and the second part 6 of the capsule 4 are separated from each other without contact, so that the dental restoration fixed to the support 3 can be accessed. At least, the packaging device 1 can be transformed once from its original configuration to its closed configuration (when packaging the dental restoration) and then once from its closed configuration to its open configuration (when unpacking the dental restoration). Therefore, the packaging device 1 can be used once. As a variant, the packaging device 1 can also be reused multiple times.

[0042] According to the embodiment shown, when the packaging device is in a closed configuration, the capsule 4 has a generally cylindrical shape with a circular bottom. The first part 5 and the second part 6 of the capsule are two half shells of the capsule with substantially the same shape. In particular, the two half shells each have the shape of a semi-cylinder. As a variation, any other shape can be proposed, such as a cylindrical shape with a polygonal bottom, in particular a rectangular bottom, or a spherical or oval shape. The axis Z can be defined as an axis parallel to the generatrix of the cylindrical shape of the capsule and passing through its center. The base 2 has a generally elongated shape along the axis Z. The first end 7A, 8A of each arm 7, 8 is connected to the first end 2A of the base 2. The support 3 is arranged at the second end 2B of the base, and the second end 2B is opposite to the first end 2A. In particular, the support 3 is in the form of a blind hole extending along the axis Z. The blind hole can have a profiled cross-section, thereby allowing the dental restoration to be inserted and removed by a simple translation movement parallel to the axis Z. In the context of this description, it is assumed that the axis Z is a vertical axis and the base is placed on a horizontal plane. The terms "lower" and "upper" relate to the arrangement along the axis Z. The packaging device is advantageously symmetrical or quasi-symmetrical with respect to a plane passing through the axis Z.

[0043] The base 2 may also be inscribed in a cylindrical shape centered on the axis Z. Advantageously, the base 2 has a concave portion to allow each arm 7, 8 to bend in the direction of the base 2. The base 2 thus comprises a relatively thin central portion 9 surrounded by a wider lower portion 10 and a wider upper portion 11. The base 2 thus has an overall hourglass shape.

[0044] The base 2 comprises two pivot members 12 and 13 for each of the two arms 7 and 8, respectively. The two pivot members 12, 13 are arranged at the second end 2B of the base, that is, at the upper part 11 of the base. The two pivot members 12, 13 can be in the form of a plate extending substantially perpendicular to the axis Z. When the packaging device is in a closed configuration, the second end 7B and 8B of each arm can be in contact with the pivot members 12 and 13, respectively, or at a slight distance. The pivot members 12, 13 are intended to form a pivot point for each of the two arms 7 and 8. The bending of the first arm 7 between its first end 7A and the first pivot member 12 causes the first part 5 of the capsule 4 to pivot around the first pivot member 12. Similarly, the bending of the second arm 8 between its first end 8A and the second pivot member 13 causes the second part 6 of the capsule 4 to pivot around the second pivot member 13.

[0045] Packing device also comprises retaining piece, and retaining piece is configured to packing device is remained in closed configuration.This retaining piece comprises two lugs 16 and two lugs 17 that are used for the first part 5 of capsule 4 being remained in closed configuration and the second part 6 of capsule 4 being remained in closed configuration.Lug 16 and 17 are intended to cooperate with the second end 7B and 8B of each arm respectively.Lug 16,17 forms the fastening clip that can apply holding force to the back of each arm.Therefore, lug 16 and 17 allow to keep arm 7 and 8 against pivot member 12 and 13 respectively or keep apart from pivot member 12,13 micro-distance.As modification, single lug 16,17 may just be enough to the first part 5 or the second part 6 being remained in closed configuration.Each lug 16,17 is intended to be out of shape, so that when packing device is converted to its closed configuration from its original configuration, allow described at least one arm to move.

[0046] according to Fig.10 In the embodiment shown, the above-mentioned retainer can be replaced or supplemented with a second retainer. The second retainer is formed by a fastening clip 27 arranged between the two parts 5 and 6 of the capsule 4. Each of the parts 5 and 6 of the capsule 4 includes interlocking surfaces 28 and 29, which cooperate with each other to keep the packaging device in a closed configuration. These interlocking surfaces 28 and 29 can extend along the entire contact line between the first part 5 and the second part 6 of the capsule. In this case, these interlocking surfaces can advantageously form baffles, thereby improving the sealing of the packaging device. Alternatively, the interlocking surfaces can extend along only a portion of the contact line, for example, only at the upper end of the parts 5 and 6 of the capsule 4. Therefore, the fastening clip is simple to produce, and the force required for opening the packaging device is also reduced. According to another variation, when the packaging device is in a closed configuration, the two parts 5 and 6 can also be weakly welded or glued together to each other.

[0047] like Figure 3As shown, each of the two parts 5 and 6 of the capsule has a cutout 18 or a cutout 18 at its lower end. These cutouts 18 allow each of the two parts 5 and 6 to pivot between the original configuration or open configuration and the closed configuration without interfering with the pivot members 12 and 13. The upper part 11 of the base 2 includes two side wings 19, which surround the support 3 and are located on the plate forming the pivot members 12 and 13. The two side wings 19 have a shape suitable for filling the cutouts 18 when the packaging device is in the closed configuration. In this case, the two side wings 19 have a generally triangular shape.

[0048] When the packaging device is in the original configuration, the two arms 7 and 8 have an arc shape. The two parts 5 and 6 of the capsule extend substantially horizontally and below the height of the dental restoration fixed to the support 3. The dental restoration can then be accessed quite easily. When the packaging device is in the closed configuration, the two arms 7 and 8 have a straight-line shape portion. This straight-line shape extends from the first end 2A of the base to the pivot members 12, 13. Each arm 7, 8 also has a bend 24 around the pivot members 12, 13 at its second end 7B, 8B, respectively. Thus, the arms 7, 8 end in a horizontal portion extending from the pivot members 12, 13 to the lower end of each part 5, 6 of the capsule.

[0049] Advantageously, the packaging device comprises a first rib 20 extending on the outer surface of each part 5, 6 of the capsule until its corresponding arm 7, 8. The packaging device also comprises a second rib 15 arranged in the bend 24 of each arm 7, 8. The plate forming the two pivot members 12, 13 advantageously comprises two notches 14, in which the second rib 15 is positioned when the packaging device is in the closed configuration. The first rib 20 and the second rib 15 allow the interface between each part 5, 6 of the capsule 4 and its corresponding arm 7, 8 to be strengthened so that the pivoting of the second end of each arm well causes the pivoting of the corresponding capsule part. As a variant, the packaging device can include only the first rib 20 or only the second rib 15, or include any other form of ribs, even without ribs, as long as the connection between each arm and the corresponding capsule part is sufficiently rigid, for example due to a sufficiently large material thickness.

[0050] According to a refinement of the invention, the base 2 comprises at least one hole for a fastening screw that can be matched with a dental restoration. In this case, the base 2 comprises two holes 21, 22 in which two fastening screws 25, 26 of different sizes can be accommodated. The holes are blind holes of circular cross section. The first hole 21 extends parallel to the axis Z in the lower part 10 of the base. The second hole 22 also extends perpendicular to the axis Z in the bottom 10 of the base between the two arms 7 and 8. Thus, it can be provided Fig. 9A kit K is shown, which comprises a dental restoration P fixed to a support 3 and two fastening screws 25, 26 arranged in each of the two holes 21, 22. Alternatively, the kit may comprise only a single one of the two fastening screws, or even any other accessory intended to cooperate with the dental restoration.

[0051] Advantageously, the packaging device is manufactured in one piece by injection molding. It is therefore particularly simple and cost-effective to manufacture. By definition, the packaging device is manufactured in its original configuration, i.e. in accordance with the Figure 1 , 3 1 and 5. On the one hand, this has the advantage that the packaging device is immediately ready to receive the dental restoration in its support. On the other hand, this provides the packaging device with a shape memory corresponding to its original configuration. Thus, the arms 7 and 8 have an elasticity which, after the first end 7A, 8A of each arm has been clamped in the fastening clip formed by the tabs 16 and 17, tends to move each portion 5, 6 of the capsule towards a position corresponding to the closed configuration of the packaging device. This allows the packaging device to be well kept in the closed configuration.

[0052] The first part 5 and / or the second part 6 of the capsule 4 can be made of a transparent plastic material and can have a three-dimensional scale 23, which is configured to estimate the size of the dental restoration contained in the capsule 4. The scale 23 can be formed in a positive three-dimensional style (i.e., convex) or a negative three-dimensional style (i.e., concave). Therefore, the user can compare the height of the dental restoration held in the support 3 with the scale 23 and estimate its size without opening the capsule 4. The scale 23 can be directly formed during the injection molding process of the packaging device. Therefore, the integration of these scales 23 does not require a specific marking operation.

[0053] Reference Figure 5 To package the dental restoration P into the packaging device 1, the following method can be used. The packaging device is manufactured by injection molding. The dental restoration P is manufactured in parallel. Figure 5 In the embodiment shown, the dental restoration P is a dental implant intended to be screwed into the bone structure of the patient. The dental implant is connected to the breakable part S ( Fig. 9), by which the dental implant is fixed to the support 3. As a variant, the dental implant may not be connected to such a breakable component, but may be fixed directly to the support 3. However, the advantage of using a breakable component is that the dental restoration P is stored without contact with the packaging device 1, thereby avoiding any risk of contamination. The breakable component S is inserted into the support 3 by a simple translation movement parallel to the axis Z, as shown by the arrow F1. Then, the first part 5 and the second part 6 of the shell are closed around the dental restoration P. The two parts 5 and 6 are pivoted about a quarter of a turn in the direction of the axis Z, as shown by the arrow F2. When the packaging device is about to reach its closed configuration, the protrusions 16 and 17 are slightly deformed to allow the arms 7 and 8 to pass against the pivot members 12 and 13. If necessary, the interlocking surfaces 28 and 29 engage with each other. Therefore, the packaging device is well maintained in the closed configuration. A kit K is thus obtained, which includes a packaging device 1 and a dental restoration P fixed to the support 3 of the packaging device. The kit K can be completed by fastening one screw 25 or 26 or two screws 25 and 26 into the holes 21 and 22 provided for this purpose. The dental restoration is thus well protected and can be transported from the place of manufacture to the place of use and stored without the risk of contamination.

[0054] When the dentist then wishes to install the dental restoration in the patient's mouth, he can first easily select a dental restoration of appropriate size with the aid of the scale 23. The packaging device can then advantageously be manipulated with one hand. As indicated by arrow F3, the first arm 7 and the second arm 8 can be pressed or pinched approximately between their ends by the thumb and index finger of one hand. This causes the two arms 7 and 8 to bend in the direction of the base. Thus, as shown in FIG. Figure 7 and Figure 8 As shown, the two arms 7, 8 are transformed from a generally straight shape into a shape that is bent in the direction of the base. The bending of the two arms 7 and 8 results in a tensioning force on the second ends 7B and 8B, respectively. Through the reaction force of the pivot members 12, 13, this tensioning force manifests itself as a rotation of the second ends 7B and 8B around the pivot members 12, 13, as shown by the arrow F4. The two parts 5 and 6 of the capsule are connected to the second ends 7B and 8B, so that they also pivot according to the arrow F5. The ribs 15, 20 allow strengthening the connection between the second ends 7B and 8B and the two parts 5 and 6 of the capsule, which allows a good transmission of the forces applied to the arms 7 and 8 to the two parts 5 and 6 of the capsule. As a result, the two parts 5 and 6 of the capsule are separated from each other and the dentist can access the dental restoration. The two arms 7, 8 are flexible because they can be fully bent by the clamping force between two fingers to cause the two parts of the capsule to pivot.

[0055] Since only one hand is needed to open the packaging device, the dentist can easily grasp the dental restoration P with his other hand without any risk of dropping it. If necessary, he can apply a twisting force on the dental restoration P to separate it from the breakable part S, which then remains in place in the support 3.

[0056] In the open configuration, the two arms 7, 8 are still held by the holder. The two parts 5 and 6 of the capsule may extend along two axes forming an angle of about 180°, such as Figure 8 As a variant, the open configuration of the packaging device may not completely correspond to Figure 8 In contrast, in the open configuration, the packaging device may be in the closed configuration ( Figure 2 , 4 and shown in 6) and Figure 8 For example, the open configuration can also be Figure 7 In the open configuration, the two parts 5 and 6 of the capsule can extend along two axes that preferably form an angle greater than or equal to 60°, in particular greater than or equal to 90°. In any case, in the open configuration, the two parts 5 and 6 of the capsule are sufficiently separated from each other to allow easy access to the dental restoration.

[0057] According to an embodiment variant not shown, as described above, the packaging device can include only one of the two arms 7, 8. Then only one of the two parts 5, 6 of the capsule 4 can be fixed relative to the base 2. The movement of the parts 5, 6 connected to the single arm is sufficient to provide access to the dental restoration. In this embodiment variant, the two parts 5 and 6 of the capsule can advantageously be asymmetric. Therefore, the manufacture of the packaging device of this variant can be further simpler. However, the packaging device in which both parts of the capsule are movable relative to the base and include two arms each connected to a part of the capsule has the following advantages: when the capsule is in an open configuration, a larger spacing between the two parts of the capsule is provided, which is conducive to taking the dental restoration.

[0058] according to Fig.11 and Fig.12 In another embodiment shown, each arm 7, 8 may include a bearing surface 30 extending generally radially outward, that is, perpendicular to the axis Z. To open the packaging device, the user can place his thumb on the lower surface of the base 2 and his index finger and middle finger on the two bearing surfaces respectively. The bearing surfaces may have a curved shape suitable for receiving the index finger and middle finger when necessary. This grip is similar to the grip of a syringe. To open the packaging device, the user can apply a downward pulling force on each bearing surface (in the same manner as pressing a syringe). As mentioned above, this pulling force will cause the two parts of the capsule to pivot through the reaction of the second end on the pivot member.

[0059] The various embodiments described can be combined with one another. Fig.11 and Fig.12 A variant embodiment of can be realized by a single arm of the two arms 7 and 8 . Fig.11 and 12 The embodiment variants of and the embodiment variant realized with a single one of the two arms 7 and 8 may comprise a fastening clip 27 arranged between the two parts of the enclosure.
