Description

  The present invention relates to a dental implant package.

  Dental implant surgery is one of the treatments for patients who have lost their teeth due to periodontal disease and other injuries. Dental replacement is a dental substitute for the patient's jawbone (alveolar bone). Implant the implant. A dental implant member implanted in the alveolar bone is called a fixture, and the fixture fixes a denture (a denture, a prosthesis of a crown portion) via an abutment or the like.

  The above fixture is manufactured in a factory and then transferred to an operating room such as a dental clinic in a state of being accommodated in a dental implant package. Various configurations are known as such dental implant packages (see, for example, Patent Documents 1 and 2).

  The dental implant package described in Patent Document 1 is used to accommodate a one-piece type dental implant fixed to an alveolar bone. This dental implant is entirely composed of one part, and has a configuration in which an alveolar bone embedding part, a gingival contact part, and an artificial dental crown holding part are arranged in series. The gingival contact part is formed in a thicker shape than the alveolar bone embedding part.

  The dental implant package that accommodates the dental implant includes a middle container, a case ring, and a case cap. The case ring is held in the inner container. The case cap is located above the case ring and is attached to the middle container. And a case ring hold | maintains the outer peripheral part of a gingival contact part, and a case cap hold | suppresses the upper end part of an artificial dental crown holding | maintenance part. Thereby, the dental implant is held in the middle container while being sandwiched between the case ring and the case cap. At this time, the middle container is arranged separately from the alveolar bone embedding part. With this configuration, the alveolar bone embedding part is suppressed from being contaminated by contact with the middle container.

  The dental implant packaging container described in Patent Literature 2 includes a main body, a leveler, a first lid, a second lid, and a protective ring. A partition wall is provided inside the main body. The partition wall separates the fixture housing space and the auxiliary housing space. Both ends of the main body have a first opening and a second opening. The leveler is accommodated in the fixture accommodating space and supports the fixture at a predetermined height. The first lid closes the first opening, and the second lid closes the second opening. The guard ring is coupled to the end of the body that forms the first opening. The fixture is fixed in the fixture accommodating space by a leveler, a protective ring, or the like.

Utility Model No. 3184171 Specification Japanese Patent No. 5131179

  In the configuration described in Patent Document 1, it is necessary to prepare a case cap having a shape that matches the size (size) of the fixture. For this reason, it is necessary to prepare a case cap of an appropriate size for each dental implant having a different size, and the versatility of the dental implant package is low.

  In the configuration described in Patent Document 2, it is necessary to prepare a leveler having a shape that matches the size (size) of the fixture. For this reason, it is necessary to prepare an appropriately sized leveler for each dental implant having a different size, and the versatility of the dental implant package is low.

  In view of the above circumstances, the present invention can more reliably suppress contamination in a contact portion of a fixture with a patient's bone in a dental implant package, and can be used for fixtures having different sizes. The purpose is to be able to increase the sex.

  (1) A dental implant package according to the present invention for achieving the above object has a lower end portion inserted into the back side of a patient's alveolar bone and an upper end portion as an end portion opposite to the lower end portion. A dental implant package for accommodating a fixture, and a body case having an opening that allows the fixture to be taken in and out, a receiving chamber that is continuous with the opening and can accommodate the fixture, and the opening A cover case capable of opening and closing a portion, a lower end stopper for supporting the lower end portion of the fixture in the accommodation chamber, and an upper end stopper for supporting the upper end portion of the fixture in the accommodation chamber. The main body case has a holding portion for holding the lower end stopper, and the holding portion is arranged in front of the lower end stopper. The lower end stopper is held so that the distance between the upper end stopper and the upper end stopper can be changed. The lower end stopper is formed of a biocompatible material, and the upper end stopper is the upper end portion or the upper end of the fixture. It is comprised so that the member fixed to the part can be received.

  According to this configuration, the fixture is supported by the main body case by being sandwiched between the upper end stopper and the lower end stopper in the housing case of the main body case. As a result, the fixture is accommodated in the accommodation chamber without contacting the main body case and the cover case. Therefore, it is suppressed that contamination arises in a contact part with an alveolar bone among fixtures. In addition, the upper end of the fixture has a small degree of contact with the bone tissue of the patient's alveolar bone. For this reason, even if contamination occurs in the upper end portion of the fixture due to contact between the upper end portion of the fixture and the upper end stopper, inflammation of the bone tissue of the patient can be suppressed. Moreover, although the lower end part of a fixture is a part which contacts the bone tissue of a patient's alveolar bone, it contacts with the lower end stopper which has biocompatibility. Therefore, even if a part of the surface of the lower end stopper adheres to the lower end portion of the fixture due to the contact between the lower end portion of the fixture and the lower end stopper, the attached matter contacts the bone tissue of the patient's alveolar bone. Can suppress inflammation. Moreover, the bone tissue of the alveolar bone is mainly bonded to the outer periphery of the fixture, and the degree of connection with the lower end of the fixture is small. Therefore, even if the material of the lower end stopper adheres to the lower end portion of the fixture, the degree of inflammation with the bone tissue is sufficiently small. The lower end stopper can be displaced with respect to the upper end stopper. Accordingly, the position of the lower end stopper can be adjusted according to the size of the fixture. For this reason, it is not necessary to prepare different parts for each fixture size. Therefore, in a dental implant package, versatility for fixtures having different sizes can be increased.

  As described above, according to the present invention, in the dental implant package, it is possible to more reliably suppress the occurrence of contamination in the contact portion of the fixture with the patient's bone, and versatility for fixtures having different sizes. Can be high.

When the is opened, it is exposed to the outside of the main body case together with the storage chamber.

  According to this configuration, when the opening is opened by the cover case being displaced with respect to the main body case, the cooperating member is exposed to the outside of the main body case together with the fixture. Thereby, the surgeon can further simplify the work of removing the fixture from the main body case and the work of removing the cooperating member from the main body case.

  (6) Preferably, a sub stopper capable of receiving an outer periphery of the upper end portion of the fixture is further provided, and the sub stopper is formed of a material having biocompatibility.

  According to this structure, the sub stopper can more reliably prevent the fixture from coming into contact with the main body case by receiving the outer peripheral portion of the upper end portion of the fixture. Further, the sub stopper is formed of a material having biocompatibility. For this reason, even when a part of the surface of the sub-stopper adheres to the upper end of the fixture, it is possible to prevent the fixture from being contaminated. In particular, a fixture of the type in which substantially the entire outer peripheral surface of the fixture is embedded in the jawbone can be held in the main body case in a state where contamination of the fixture is more reliably suppressed.

  (7) Preferably, the fixture is configured to be accommodated in the accommodation chamber in a state in which a predetermined mount is coupled to the upper end portion of the fixture, and the dental implant package includes: A support member that receives the mount and is held by the main body case is further provided.

  FIG. 1 is a perspective view of a dental implant package 1 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1 and shows a state in which the fixture 2 and the cover screw 3 as a member of the dental implant are accommodated in the dental implant package 1. FIG. 3 is a side view of the dental implant package 1. FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG. 2, and illustration of members that can be seen on the back side of the cross section is omitted.

  1 to 4, a dental implant package 1 is used as a storage container for storing and storing a fixture 2 and a cover screw 3. Prior to the description of the dental implant package 1, the structure of the fixture 2 will be described.

  The fixture 2 is installed in the oral cavity of a patient who has lost a tooth, and is used to exhibit the function of the lost tooth in place of the tooth. The fixture 2 according to the present embodiment is a so-called bone level specification fixture 2. A portion of the fixture 2 other than the upper end surface 2a is embedded in the alveolar bone or gingiva (not shown) of the patient's jawbone. The fixture 2 is fixed to a patient's alveolar bone and is provided to fix a denture (not shown) to the alveolar bone.

  The fixture 2 is formed using a material having biocompatibility. In addition, the material having biocompatibility refers to a material that is familiar to living tissue. In other words, the material having biocompatibility means a material that does not cause a long-term and chronic inflammatory reaction when it comes into contact with a living tissue and can maintain a good adhesion state with surrounding tissues. Examples of biocompatible materials include metal materials such as pure titanium, titanium alloys, cobalt-chromium alloys, stainless steel (SUS316, etc.), and ceramic materials such as alumina ceramics. In the present embodiment, the fixture 2 is formed of a metal material.

  The fixture 2 is an integrally molded product formed in an elongated rod shape. A male screw portion 2 d is formed on the outer peripheral portion of the fixture 2. The male screw portion 2d of the fixture 2 is screwed into the alveolar bone and fixed to the alveolar bone.

  The fixture 2 is screwed into the patient's alveolar bone with the gingiva covering the alveolar bone removed. Then, for example, several months after the fixture 2 is screwed into the alveolar bone, the bone cells of the alveolar bone are bonded to the outer peripheral portion of the fixture 2 (bone connection).

  The lower end 2c of the fixture 2 is inserted into the back side of the patient's alveolar bone. An upper end 2b as an end opposite to the lower end 2c is disposed in the vicinity of the surface of the patient's gingiva. The upper end surface 2a of the fixture 2 is a flat surface. The fixture 2 is formed with a hole 2 e extending from the upper end surface 2 a of the fixture 2 in the axial direction of the fixture 2. The hole 2e of the fixture 2 is a female screw hole, for example, and is provided as a tool hole for attaching the fixture 2 to the alveolar bone and a part attached to the cover screw 3.

  The cover screw 3 is a small piece member that is screwed to the fixture 2. Here, the outer peripheral part of the fixture 2 couple | bonds with the bone cell of a patient's alveolar bone. For this reason, when contamination occurs in the outer peripheral portion, there is a possibility that inflammation or the like occurs in the alveolar bone. Contamination in this case means that a substance causing the inflammation of the alveolar bone or the like adheres to the outer peripheral portion of the fixture 2. As a causative substance of such contamination, a synthetic resin can be exemplified.

The length of the thin shaft portion 33 is set shorter than the length of the thick shaft portion 31. The thin shaft portion 33 is in contact with the bottom surface of the hole 2 e of the fixture 2.

  The upper end stopper 7e does not come into contact with the portion of the fixture 2 that comes into contact with the patient's alveolar bone, nor does it come into contact with the portion that comes into contact with the patient's gingiva. Therefore, even if a part of the surface of the upper end stopper 7e adheres to the fixture 2, the adhered matter does not cause the patient to become inflamed. The thin shaft portion 33 is surrounded by the sub stopper 8.

  The sub stopper 8 is provided in the first storage chamber 13 so as to be fitted to the outer periphery of the upper end 2 b of the fixture 2. The sub stopper 8 is formed as an annular thin plate member. The sub stopper 8 is formed of a material having biocompatibility.

The lower end stopper 9 is formed as a disk-shaped thin plate member (plate-shaped member). The lower end stopper 9 is formed of a material having biocompatibility. In the present embodiment, the lower end stopper 9 is formed of the same material as that of the fixture 2. The same material means that, for example, if the fixture 2 is made of titanium alloy or pure titanium, the lower end stopper 9 is made of various titanium alloys or pure titanium whose main constituent is titanium. This does not mean that they must be made of exactly the same material. The central portion of the lower end stopper 9 has a hollow portion 9 a and is formed in a curved shape corresponding to the shape of the lower end portion of the fixture 2.

  Further, the lower end stopper 9 is held in the holding groove portion 20. That is, the outer diameter of the lower end stopper 9 is set to a value that allows the lower end stopper 9 and the holding groove portion 20 to be fitted. The lower end stopper 9 is positioned and held in the main body case 5 by being fitted into any one of the plurality of holding groove portions 20. With such a configuration, the holding portion 19 can hold the lower end stopper 9 in such a manner that the distance between the lower end stopper 9 and the upper end stopper 7e can be changed.

  With the above configuration, the fixture 2 is held between the upper end stopper 7e and the lower end stopper 9 in the longitudinal direction X1, and the displacement in the longitudinal direction X1 in the first storage chamber 13 is restricted. Further, the fixture 2 is received by the recess 9 a of the lower end stopper 9 and the sub stopper 8, so that the displacement in the direction perpendicular to the longitudinal direction X <b> 1 is restricted in the first storage chamber 13.

  The second cap member 10 is provided to prevent the cover case 6 from coming off the main body case 5. In the present embodiment, the second cap member 10 is provided to close the space in the connecting shaft portion 11. The second cap member 10 can be attached to and detached from the connecting shaft portion 11 of the main body case 5. In the present embodiment, the second cap member 10 uses the same material as the first cap member 7 and has the same shape as the first cap member 7. Thereby, the 1st cap member 7 and the 2nd cap member 10 can be made shared. As a result, the manufacturing cost of the dental implant package 1 can be further reduced.

  The second cap member 10 includes an outer peripheral portion 10a, an inner peripheral portion 10b, an end surface portion 10c, a bottom surface portion 10d, and an upper end stopper 10e.

  The outer peripheral part 10a and the inner peripheral part 10b are formed in a cylindrical shape. The outer peripheral part 10a surrounds the inner peripheral part 10b. The overall length of the outer peripheral portion 10a is made larger than the overall length of the inner peripheral portion 10b. The outer peripheral surface of the outer peripheral part 10a has uneven undulations, and forms an anti-slip part that is touched by the operator's finger. One end portion of the outer peripheral portion 10a and one end portion of the outer peripheral portion 10a are connected to each other by the end face portion 10c.

  The inner peripheral part 10 b is press-fitted and fixed to the connecting shaft part 11.

  The upper end stopper 10 e is provided to support a member accommodated in the space in the connecting shaft portion 11. The upper end stopper 10e is formed in an axial shape extending from the bottom surface portion 10d along the longitudinal direction X1.

  The procedure for attaching the fixture 2 and the cover screw 3 to the dental implant package 1 having the above-described configuration is as follows. That is, in the factory for manufacturing the fixture 2 and the cover screw 3, the worker opens the opening 18 by operating the cover case 6. Accordingly, the first storage chamber 13 and the second storage chamber 14 are exposed to the outside of the dental implant package 1 through the opening 18.

  In this state, the worker accommodates the cover screw 3 in the second accommodating chamber 14 and accommodates the fixture 2 in the first accommodating chamber 13. At this time, the fixture 2 is accommodated in the first accommodation chamber 13 so as to be fitted to the sub stopper 8 and to be received by the lower end stopper 9. Next, when the worker displaces the cover case 6 around the connecting shaft portion 11, the cover case 6 is displaced so as to close the opening 18.

  Next, the worker press-fits the inner peripheral portion 7 b of the first cap member 7 into the second opening 30 (cylindrical portion) formed by the first extending portion 16 and the second extending portion 25. Accordingly, the upper end stopper portion 7e of the first cap member 7 presses the upper end portion 2b of the fixture 2.

  Next, the dental implant package 1 is accommodated in a packaging container (not shown). Next, the fixture 2 and the cover screw 3 accommodated in the dental implant package 1 are sterilized by γ-ray irradiation by a γ-ray irradiation device (not shown).

  When the fixture 2 is taken out from the dental implant package 1, first, the operator takes out the dental implant package 1 from the packaging container. Next, the surgeon pulls out the first cap member 7 from the main body case 5 and the cover case 6. Then, the operator opens the opening 18 by displacing the cover case 6 around the connecting shaft portion 11. In this state, the operator takes out the fixture 2 and the cover screw 3 from the corresponding first storage chamber 13 and second storage chamber 14. The surgeon may take out the fixture 2 from the second opening 30 without displacing the cover case 6 around the connecting shaft portion 11.

  As described above, according to the dental implant package 1 according to the present embodiment, the fixture 2 is sandwiched between the upper end stopper 7e and the lower end stopper 9 in the first storage chamber 13 of the main body case 5, so that the main body Supported by the case 5. As a result, the fixture 2 is accommodated in the first accommodating chamber 13 without contacting the main body case 5 and the cover case 6 made of synthetic resin. Therefore, contamination of the fixture 2 in contact with the alveolar bone (the outer peripheral portion of the fixture 2) is suppressed. Further, the upper end portion 2b of the fixture 2 has a small degree of contact with the bone tissue of the patient's alveolar bone. For this reason, even if contamination occurs in the upper end 2b of the fixture 2 due to the contact between the upper end 2b of the fixture 2 and the upper end stopper 7e, inflammation of the bone tissue of the patient can be suppressed. Moreover, although the lower end part 2c of the fixture 2 is a part which contacts the bone tissue of a patient's alveolar bone, it contacts the lower end stopper 7e having biocompatibility. Therefore, even if a part of the surface of the lower end stopper 9 adheres to the lower end portion 2c of the fixture 2 due to the contact between the lower end portion 2c of the fixture 2 and the lower end stopper 9, the adhering matter is attached to the patient's alveolar bone. Inflammation caused by contact with bone tissue can be suppressed. Moreover, the bone tissue of the alveolar bone is mainly bonded to the outer peripheral portion of the fixture 2, and the degree of connection with the lower end 2 c of the fixture 2 is small. Therefore, even if the material of the lower end stopper 9 adheres to the lower end portion 2c of the fixture 2, the degree of inflammation with the bone tissue is sufficiently small. The lower end stopper 9 can be displaced with respect to the upper end stopper 7e. Thereby, the position of the lower end stopper 9 can be adjusted according to the size of the fixture 2. For this reason, it is not necessary to prepare different parts for each size of the fixture 2. Therefore, in the dental implant package 1, versatility for fixtures having different sizes can be enhanced.

  Depending on the above, in the dental implant package 1, it is possible to more reliably suppress the occurrence of contamination at the contact portion of the fixture 2 with the patient's bone, and to increase the versatility of fixtures having different sizes. .

  Further, according to the dental implant package 1, the lower end stopper 9 is formed of the same material as that of the fixture 2. According to this configuration, even if a part of the surface of the lower end stopper 9 is attached to the fixture 2, when the fixture 2 is bonded to the bone tissue of the patient, inflammation caused by the attached matter occurs. Can be suppressed.

  Moreover, according to the dental implant package 1, the lower end stopper 9 is formed in a plate shape. According to this structure, the lower end stopper 9 can be made into a simple shape. The lower end 2c of the fixture 2 has a hemispherical convex shape. For this reason, the contact area of the lower end stopper 9 and the fixture 2 can be made smaller. Thereby, it can suppress more reliably that a part of surface of the lower end stopper 9 adheres to the fixture 2. FIG.

  Further, according to the dental implant package 1, the lower end stopper 9 is alternatively held in the plurality of holding groove portions 20 formed in the main body case 5. According to this configuration, the position of the lower end stopper 9 can be easily set with a simple configuration in which the lower end stopper 9 is fitted into any of the plurality of holding groove portions 20.

  Further, according to the dental implant package 1, the second storage chamber 14 of the main body case 5 is exposed to the outside of the main body case 5 together with the first storage chamber 13 when the opening 18 is opened. According to this configuration, when the opening 18 is opened by the cover case 6 being displaced with respect to the main body case 5, the cover screw 3 housed in the second housing chamber 14 is moved together with the fixture 2 to the main body case 5. Exposed to the outside. Thereby, the surgeon can further simplify the work of removing the fixture 2 from the main body case 5 and the work of removing the cover screw 3 from the main body case 5.

  Further, according to the dental implant package 1, the sub stopper 8 receives the outer peripheral portion of the upper end portion 2 b of the fixture 2. Thereby, it can prevent more reliably that the fixture 2 contacts the main body case 5. FIG. The sub stopper 8 is formed of a material having biocompatibility. For this reason, even when a part of the surface of the sub stopper 8 adheres to the upper end portion 2b of the fixture 2, it is possible to prevent the fixture 2 from being contaminated. In particular, the fixture 2 of the type in which substantially the entire outer peripheral portion of the fixture 2 is embedded in the alveolar bone or gingiva is held by the main body case 5 in a state where contamination of the fixture 2 is more reliably suppressed.

  Further, according to the dental implant package 1, since the connecting mechanism 27 is provided, the operator can open the opening 18 by a simple operation of rotating the cover case 6 with respect to the connecting shaft portion 11 of the main body case 5. Can be opened.

  Further, according to the dental implant package 1, the upper end stopper 7 e can be coupled to the upper end surface 2 a of the upper end portion 2 b of the fixture 2. According to this configuration, the upper end stopper 7e can hold the fixture 2 while avoiding contact with a portion of the fixture 2 that is coupled to the patient's alveolar bone. Thereby, it can suppress more reliably that the upper end stopper 7e contaminates the fixture 2. FIG.

  Further, according to the dental implant package 1, the operator can take out the fixture 2 in the first storage chamber 13 by removing the first cap member 7 from the main body case 5. Thereby, the surgeon can take out the fixture 2 from the main body case 5 without opening the cover case 6.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, As long as it described in the claim, various changes are possible. For example, the following modifications may be made.

  (1) In the above-described embodiment, the example in which the fixture 2 of the type in which the entire outer peripheral portion is embedded in the alveolar bone or gingiva is accommodated in the dental implant package 1 has been described as an example. However, this need not be the case. For example, as shown in FIG. 5, a fixture 2 </ b> A of a type in which a part of the outer peripheral portion is embedded in alveolar bone or gingiva may be accommodated in the dental implant package 1.

  The fixture 2A is a so-called one-piece type fixture. The fixture 2A is formed in an elongated shaft shape in the longitudinal direction X1, and the fixture 2A includes an embedded portion 50 embedded in the patient's alveolar bone or gingiva, and an exposed portion 51 exposed from the patient's gum.

  The lower end 2c of the fixture 2A is received by the lower end stopper 9. The lower end stopper 9 is held by the holding groove portion 20 at a position farthest from the upper end stopper 7e among the plurality of holding groove portions 20.

  Thus, the dental implant package 1 can accommodate a fixture 2A having a size different from that of the fixture 2 with a simple configuration in which the position of the lower end stopper 9 with respect to the main body case 5 is changed.

  (2) Moreover, in the above-mentioned embodiment and modification, the fixture 2 and 2A demonstrated to the example the form accommodated in the dental implant package 1 in the state of a single item. However, this need not be the case. For example, as shown in FIG. 6 and FIG. 7, which is a cross-sectional view taken along the line VII-VII in FIG. 6, the dental implant package 1 may accommodate the fixture 2 </ b> B to which the mount 55 is attached.

  The fixture 2B is a so-called tissue level (Tissue Level) fixture. The fixture 2B has a configuration in which an alveolar bone embedded part 50 and a gingival contact part 52 are arranged in order in the longitudinal direction X1.

  The alveolar bone embedding part 50 is a site | part embed | buried in a patient's alveolar bone, and has the external thread part which is not shown in the outer peripheral surface. The alveolar bone embedding part 50 includes the lower end part 2c of the fixture 2B. The gingival contact portion 52 is a portion that contacts the patient's gingiva, and extends from the alveolar bone embedded portion 50 in one of the longitudinal directions X1. The gingival contact portion 52 is a portion having a tapered outer peripheral surface, and has a shape in which the outer diameter increases as the distance from the alveolar bone embedded portion 50 increases. The gingival contact portion 52 includes the upper end portion 2b of the fixture 2B. A female screw portion 53 is formed on the upper end portion 2b.

  The female screw portion 53 is provided, for example, as a portion to which the cover screw 3 is fixed after the fixture 2B is fixed to the alveolar bone. In a state before the fixture 2B is installed on the patient, the mount 55 is fixed to the female screw portion 53. That is, the fixture 2B is accommodated in the first accommodation chamber 13 in a state where the mount 55 is coupled to the upper end 2b of the fixture 2B.

  The mount 55 is used to transport the fixture 2B from the first storage chamber 13 to the patient's alveolar bone. The mount 55 is formed in a quadrangular prism shape, for example. A male screw portion 56 is formed at the lower end portion of the mount 55. The male screw portion 56 is screwed to the female screw portion 53 of the fixture 2B. A hole 57 is formed in the mount 55. The thin shaft portion 33 of the upper end stopper 7e of the first cap member 7 is fitted in the hole portion 57. Further, the blade portion 32 of the upper end stopper 7 e is coupled to the upper end surface 58 of the upper end portion of the mount 55 and presses the upper end surface 58.

  In this modification, the dental implant package 1 further includes a support member 40.

  The support member 40 is provided as a portion that receives the mount 55 and is held by the main body case 5. The support member 40 is formed of the same material (synthetic resin) as the main body case 5. Mount 55 is not a member intended to touch the patient. For this reason, the support member 40 that supports the mount 55 may not have biocompatibility.

  The support member 40 has a groove fitting part 41, an intermediate part 42, and a clamping part 43.

  The groove fitting part 41 is provided as a part fitted to the holding groove part 20 of the main body case 5. The groove fitting part 41 is formed in a semicircular shape, for example, and is formed so as to be fitted into the holding groove part 20. The groove fitting portion 41 is opened toward the opening 18 side. A semicircular receiving portion 41 a extends from the groove fitting portion 41 and is received by the inner surface of the first storage chamber 13. With the above configuration, the support member 40 and the main body case 5 are more reliably coupled. The groove fitting portion 41 is continuous with the intermediate portion 42.

  The intermediate portion 42 is provided as a portion extending from the groove fitting portion 41 to the first cap member 7 side along the longitudinal direction X1. The intermediate part 42 is disposed adjacent to the bottom part of the groove fitting part 41. A sandwiching portion 43 is continuous with the intermediate portion 42.

  The clamping part 43 is provided as a part for clamping the mount 55. The sandwiching portion 43 has a pair of arms 43a and 43a, and the arms 43a and 43a sandwich, for example, the upper end portion of the mount 55. The clamping part 43 is opened toward the opening part 18 side. With the above configuration, the fixture 2 </ b> B in the first storage chamber 13 can be pulled out from the clamping unit 43 while being held by the surgeon's finger when the opening 18 is opened.

  As described above, in this modification, the fixture 2 is held by the main body case 5 via the mount 55. Thereby, the fixture 2 is more firmly held in the main body case 5.

(3) FIG. 8 shows another embodiment of the present invention. In the present embodiment, the main body case 5 further includes a case stand portion 61 for stably placing the dental implant package 1 in an upright state in the longitudinal direction X1. The case stand part 61 is formed in the lower end part (end part on the side far from the upper end stopper 7e) of the main body case 5. The case stand unit 61 has, for example, a pair of rod-like portions extending in parallel with each other.

  Thereby, the operator can take out the fixture 2 from the second opening 30 by removing the first cap member 7 in a state where the implant package 1 is placed upright in the longitudinal direction X1 and placed on the operating table or the like. It becomes possible. Further, depending on the shape of the fixture 2, the fixture 2 can be taken out from the opening 18.

  According to this configuration, the first cap member 7 can be separated from the cover case 6 and the main body case 5 in a state where the main body case 5 is stably upright by the case stand portion 61, and the first cap member 7 is covered. The fixture 2 can be easily taken out from the main body case 5 through the second opening 30 that has been broken. Even if the case stand portion 61 is not provided, if the longitudinal direction X1 of the implant package 1 is maintained substantially perpendicular to the ground by gripping or the like, the first cap is the same as when the case stand portion 61 is made to stand upright. Although it is possible to remove the member 7 and take out the fixture 2 from the second opening 30, the case stand 61 is more preferable because it can stand upright and be stable.

  (4) Moreover, in the above-mentioned embodiment and each modification, the 1st cap member 7 demonstrated as an example the form press-fixed by the main body case 5 and the cover case 6. However, this need not be the case. For example, the first cap member 7 may be screwed to the main body case 5 and the cover case 6. In this case, a male screw portion is formed on one of the main body case 5 (cover case 6) and the first cap member 7, and a female screw portion is formed on the male screw portion on the other side.

  The present invention can be widely applied as a dental implant package.
