Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and more specifically relates to a bendable base support device for oral implant bone augmentation. Background Art

[0002] Oral implant treatment is often accompanied by alveolar bone defects in the implant area. Artificial bone powder or autologous bone chips are routinely used for bone augmentation GBR. Bone augmentation GBR must strictly follow the classic "PASS" principle, namely, primary wound closure, angiogenesis, space maintenance, and stability of the bone augmentation area. Among them, good space in the bone defect area, especially the space in the alveolar ridge crest of the implant neck, is the most important and most difficult factor to achieve for successful bone augmentation.

[0003] However, currently most implant spaces are maintained using rigid structures, such as titanium meshes, titanium bars, or tent titanium nails. Therefore, not only are the installation flexibility poor, but they are also prone to penetrate the gingival mucosa during the healing process, especially the alveolar ridge crest area, causing the support space to collapse and resulting in bone augmentation failure.

The diameter of the support member 3 is 6-10mm, preferably 8mm, and the thickness of the support member 3 is 0.5-1mm, preferably 0.8mm, so that the bone formation space of 1mm vertical bone defect and 2-3mm labial and lingual horizontal bone defect can be maintained, and other rigid support structures, such as titanium bars, can be used together to maintain a larger bone augmentation space.

[0032] In one embodiment of the utility model, a groove 31 for screwing in is provided at the center of the upper end surface of the support member 3, and a circular ring recess 32 for conveniently bending the edge of the support member 3 is provided on the outer side of the groove 31. Since the circular ring recess 32 is located at the periphery of the base 2, the edge of the support member 3 can be personalized adjusted within a limited range according to the shape of the bone defect during clinical surgery, and smooth arc bends are used as much as possible to avoid sharp edges and adjust to within the ideal bone arch contour to reduce the chance of gingival mucosal penetration.

[0033] In one embodiment of the utility model, the upper end surface of the support member 3 is also provided with four arc-shaped through holes 33 at intervals, and the four through holes 33 are respectively located on the outside of the circular recess 32, thereby ensuring that the bendable base support device for oral implant bone augmentation is a frame through structure, which will not isolate the bone blood supply while playing a supporting role, and is more conducive to new bone formation.

Preferably, the overall length of the screwdriver is 2 cm or 2.5 cm.

[0037] The method of using the bendable abutment support device for oral implant bone augmentation is to first implant the implant, ensure the initial stability is 35N / cm, and perform a small amount of bone trimming around the implant;

[0038] The bendable abutment support device for oral implant bone augmentation is further screwed in with a screwdriver, and the position, range and angle of the bend of the support member 3 are designed according to the shape of the bone defect, and the edge of the support member 3 is ensured not to exceed the ideal bone arch contour;

[0039] Further, the bendable abutment support device for oral implant bone augmentation is disassembled by using a screwdriver, and the support member 3 is bent by using a needle holder or Sande forceps outside the mouth according to the design inside the mouth;

[0040] After artificial bone powder or autologous bone chips are implanted in the bone defect area, a screwdriver is used to screw the bendable abutment support device for oral implant bone augmentation through the groove 31 and locked;

[0041] Finally, the CGF membrane or the biological membrane is covered on the bendable abutment supporting device for oral implant bone augmentation.
