Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an osteogenic space construction component for oral bone augmentation. Background Art

[0002] In clinical implant treatment, for the successful implantation and long-term stability of the implant, there is a minimum requirement for the bone volume around the implant. However, there are many reasons for alveolar bone defects in reality, and guided bone regeneration (GBR) is one of the most commonly used treatment methods to restore local bone volume. Successful GBR needs to follow four principles: ① Initial wound closure without tension; ② Adequate blood supply; ③ Construction of bone space; ④ Maintaining a stable bone environment. Among them, the construction and maintenance of bone space are considered to be the most critical factors. Pure titanium has good biocompatibility, and the titanium bar components made have certain strength and plasticity, can withstand certain external pressure, provide good space support for vertical bone augmentation and horizontal bone augmentation, ensure the stability of bone graft materials, and have good bone formation effect. Although the current titanium bar components used for bone space construction can better meet the needs of alveolar bone volume recovery, they cannot meet the needs of temporary chewing and occlusion. Only when they are restored to a certain amount can the next step of implant implantation be carried out. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a bone space construction component for oral bone augmentation, which mainly solves the technical problem that the existing titanium bar component can only meet the needs of bone space construction, but cannot simultaneously wear a temporary crown during the bone recovery stage to meet the temporary chewing and occlusion needs.

[0004] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0005] A bone formation space construction component for oral bone augmentation includes a base and a construction body for fixed connection with the alveolar bone to construct a bone formation space at the alveolar bone defect, the construction body is provided with a base screw hole, the bottom of the base is formed with a threaded portion adapted to the base screw hole, the base is locked on the construction body by screwing the threaded portion with the base screw hole, and a crown mounting portion for mounting a temporary crown is formed on the base.

[0006] Furthermore, the construction body is a long titanium strip structure, and a plurality of locking holes are provided on the construction body. The construction body is configured to be locked on the alveolar bone through the cooperation of the locking holes and locking screws.

[0007] Furthermore, a thickened portion is formed at a position where the base screw connection hole is opened on the construction body.

[0008] Furthermore, the thickened portion is formed on the bottom surface of the construction body at the position where the base screw connection hole is opened.

[0009] Furthermore, the thickness of the other parts of the construction body except the thickened part is 0.3-0.8 mm, and the thickness at the location where the thickened part is set is 1 mm-1.5 mm.

[0010] Furthermore, an anti-rotation portion is formed on the base.

[0011] Furthermore, the anti-rotation portion is a hexagonal or octagonal structure, and is configured to determine the installation direction of the temporary crown on the abutment and prevent the temporary crown from changing its original installation direction due to rotation after being installed in place on the abutment.

[0012] Furthermore, the crown mounting portion is a screw hole structure.

[0013] Furthermore, the screw hole of the base is a conical screw hole structure that is larger at the top and smaller at the bottom, and the threaded portion at the bottom of the base is a conical stud structure that is compatible with the conical screw hole structure. The threaded cooperation between the conical stud structure and the conical screw hole structure allows the base to be locked on the building body and prevents the bottom of the base from protruding from the bottom surface of the building body.

[0014] Furthermore, the internal thread in the tapered screw hole structure and the external thread on the tapered stud structure are double-thread structures that match each other.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] In the bone formation space construction component for oral bone augmentation described in the utility model, the base is screwed to the base screw hole of the construction body through the threaded part, and a crown mounting part is also arranged on the base. When the construction body is shaped as needed and fixedly mounted to the bone defect position of the alveolar bone, the bone formation space can be well constructed, and a temporary crown can be installed on the crown mounting part of the base, so that the temporary chewing and occlusal needs of the patient can be met during the bone recovery stage, thereby achieving the excellent effect of simultaneous bone augmentation and temporary occlusal repair.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] Please refer to the attached Figure 1 To Attachment Figure 6 An embodiment of the utility model provides a bone formation space construction component for oral bone augmentation, characterized in that it includes a base 1 and a construction body 2 for fixedly connecting with the alveolar bone to construct a bone formation space at the alveolar bone defect, a base screw hole 21 is provided on the construction body 2, a threaded portion 11 adapted to the base screw hole 21 is formed at the bottom of the base 1, the base 1 is locked on the construction body 2 by the screw connection between the threaded portion 11 and the base screw hole 21, and a crown mounting portion 12 for mounting a temporary crown is formed on the base 1. It can be understood that in the present embodiment, the base 1 is screwed to the base screw hole 21 of the construction body 2 through the threaded portion 11, and a crown mounting portion 12 is also provided on the base 1. When the construction body 2 is shaped as required and fixedly mounted to the bone defect position of the alveolar bone, a good bone formation space can be constructed, and a temporary crown can also be installed on the crown mounting portion 12 of the base 1. In this way, the patient's temporary chewing and occlusal needs can be met during the bone recovery stage, thereby achieving the excellent effect of simultaneous bone augmentation and temporary occlusal repair.

[0028] Please refer to the attached Figure 1 To Attachment Figure 6 In one preferred embodiment, the construction body 2 is a long titanium bar structure, and a plurality of locking holes 22 are provided on the construction body 2. The construction body 2 is configured to be locked on the alveolar bone through the cooperation of the locking holes 22 and the locking screws. It should be understood by those skilled in the art that each locking hole 22 can be correspondingly locked with a bone screw or a membrane screw, thereby fixing the construction body 2 and the bone column filled in the alveolar. In practical applications, due to the thickness of the titanium bar itself, stable plastic deformation is brought about, and in some cases, only part of the locking holes 22 can be used in combination with bone screws or membrane screws to fix the titanium bar, and the remaining locking holes 22 can also be left empty without locking bone screws, membrane screws, etc., so as to increase blood supply.

[0029] Please refer to the attached Figure 1 To Attachment Figure 6 In one preferred embodiment, a thickened portion 23 is formed at the location where the base screw connection hole 21 is opened on the construction body 2. The thickened portion 23 is formed on the bottom surface of the construction body 2 at the location where the base screw connection hole 21 is opened. Compared with the thickened portion 23 being arranged upward, in this embodiment, the thickened portion 23 is arranged to protrude downward, which can prevent the growth of soft tissue and the invasion of bacteria.

[0030] Please refer to the attached Figure 1 To Attachment Figure 6 In one preferred embodiment, the thickness of the main body 2 except the thickened portion 23 is 0.3-0.8mm, and the thickness at the location where the thickened portion 23 is set is 1mm-1.5mm. In this embodiment, preferably, the overall thickness at the location where the thickened portion 23 is set is 1mm, and the thickness of the main body 2 except the thickened portion 23 is 0.5mm. The thickness of 1mm allows the main body 2 and the base 1 to have enough matching parts to ensure the stability of the connection between the two. The remaining parts are reduced to 0.5mm thick, which will be lighter than the structure with a 1mm thick titanium bar. At the same time, while ensuring that it has sufficient strength, it is easier to control the bending operation so as to fit with the alveolar ridge.

[0031] Please refer to the attached Figure 1 To Attachment Figure 6 In one preferred embodiment, an anti-rotation portion 13 is formed on the base 1. The anti-rotation portion 13 is a hexagonal or octagonal structure, and is configured to determine the installation direction of the temporary crown on the base 1 and prevent the temporary crown from changing its original installation direction due to rotation after being installed in place on the base 1.

[0032] Please refer to the attached Figure 1 To Attachment Figure 6 In one preferred embodiment, the crown mounting portion 12 is a screw hole structure. When installing the temporary crown, the temporary crown can be locked on the base 1 by using the crown screw and the thread of the crown mounting portion 12 of the screw hole structure.

[0033] Please refer to the attached Figure 1 To Attachment Figure 6 In one preferred embodiment, the base screw hole 21 is a tapered screw hole structure that is larger at the top and smaller at the bottom, and the threaded portion 11 at the bottom of the base 1 is a tapered stud structure that matches the tapered screw hole structure. The tapered stud structure and the tapered screw hole structure are threaded together so that the base 1 is locked on the building body 2 and the bottom of the base 1 is prevented from protruding from the bottom surface of the building body 2. It can be understood that in this embodiment, the threaded cooperation between the tapered stud structure and the tapered screw hole structure can limit the screwable position of the base in the base screw hole 21, ensuring that it will not be screwed in too deeply and protrude from the bottom of the titanium strip.

[0034] Please refer to the attached Figure 1 To Attachment Figure 6 In one preferred embodiment, the internal thread in the tapered screw hole structure and the external thread on the tapered stud structure are double-thread structures that match each other. The double-thread structure makes the screwing of the base faster and more stable.

[0035] As described above, the embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model. Therefore, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the protection scope of the utility model.
