Intraoral combined tooth positioning blocky bone extraction and transplantation whole-course guide plate and manufacturing method thereof

Abstract

The invention relates to an intraoral combined tooth positioning blocky bone extraction and transplantation whole-course guide plate and a manufacturing method thereof, a bone supply area tooth positioning guide plate is connected with a positioning and trimming reference block, and the bone supply area tooth positioning guide plate is used for setting a plurality of positioning points for a bone supply area after being connected with the positioning and trimming reference block; a bone taking guide plate can be connected with the bone supply area tooth positioning guide plate and the positioning and trimming reference block, can be fixed to the bone supply area according to a plurality of positioning points, and is used for cutting out blocky bones; a bone receiving area tooth positioning guide plate can be connected with the positioning and trimming reference block through a slot, the positioning and trimming reference block is the same as a blocky bone in shape, a plurality of positioning points corresponding to the position of the bone supply area are arranged in the bone receiving area through the positioning and trimming reference block, and the obtained blocky bone can be transplanted to the bone receiving area; the intraoral autologous blocky bone can be accurately and safely obtained in a minimally invasive mode, guidance of the whole process of bone taking, bone grafting and implant implanting can be provided for doctors, the operation difficulty is reduced, and the doctors are assisted in completing the whole operation more accurately, efficiently and safely.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an intraoral combined tooth positioning block bone bone harvesting and transplantation guide plate and a production method. Background technique [0002] Autologous block bone grafting is an effective way to reconstruct severe bone defects in the proposed implant site after tooth loss. The intraoral donor site has the advantages of less trauma, good dimensional stability of the bone originating from intramembranous ossification, and high patient acceptance. It is the preferred donor site for autologous massive bone grafting. Autologous block bone grafting includes two steps of bone harvesting and bone grafting, involving two parts, the bone donor area and the bone receiving area. The most critical factor to ensure good bone reconstruction is the stable fixation between the inserted bone mass and the recipient area. How to make full use of intraoral bone sources to obtain block...

Problems solved by technology

The positioning guide plate designed by using the special shape of the tooth surface is helpful for the accurate positioning of the bone extraction guide plate. Many scholars have designed different tooth positioning bone extraction guide plates or osteotomy guide plates in order to obtain the desired block shape and volume. bone, but how to modify the removed bone block so that its inner surface fits well with the bone-receiving area, how to make the outer surface of the removed block bone reconstruct the aesthetic contour of the bone defect area, and how to ensure that the removed block bone is in accordance with The design position is accurately positioned and fixed on the bone-receiving area, etc., which still cannot be solved
