In situ bone harvesting and bone grafting guide plate for horizontal bone augmentation and manufacturing method thereof

Abstract

The invention discloses an in situ bone harvesting and bone grafting indicating guide plate and a manufacturing method thereof in horizontal bone augmentation, which solves the problem that in the prior art, bone harvesting cannot meet the requirements of bone grafting and affect the surgical effect, and bone harvesting without accurate positioning leads to damage to the anatomy of adjacent important blood vessels and nerves. Structural, or technical problems with excess bone harvesting causing additional trauma increasing surgical risk. The indicator guide includes a base plate, a bone shell acquisition guide, and a bone shell placement guide. The production method is mainly to obtain stl data by oral scan before operation, and obtain Dicom data by taking CBCT. The two data are registered and fused to design the three-dimensional position of the ideal crown to obtain the ideal gingival margin position in the edentulous area, and the ideal implant position is guided by restoration. The design thus guides the final outer surface design of the horizontal bone augmentation, designing the base plate, bone shell acquisition guide, and bone shell placement guide. The present invention accurately indicates the three-dimensional position of the bone extraction and bone grafting site, reduces surgical trauma, reduces surgical risk, shortens surgical time, avoids complications such as damage to adjacent tooth roots, and improves surgical efficiency.

Description

Technical field [0001] The present invention belongs to the technical field of medical device structure, and specifically, in the art of cascade, the primary bone cream indicator guide and its production method thereof. Background technique [0002] When dental deletions, it is often facing problems with insufficient bone volume. It is often necessary to carry out bone increments for severe horizontal to bone, and then planted surgery, regarding horizontal bone increasing. Have ONLAY bone, GBR, etc. Among them, the original bone is obtained, and the bone shell is then wrapped in GBR to perform horizontal bone increment has been widely used in the clinic. Its advantage is that it is necessary to open up the second image to complete the bone, compared to traditional online bones more minimally invasive . The conventional procedures in this bone incremental technique are proactive in operation to levy according to the bone deficiency, and then secure the bone block in the bone defic...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: to provide an in situ bone harvesting and bone grafting indicator guide plate and its manufacturing method in horizontal bone augmentation, and to solve the problem that the amount of bone harvested in the prior art cannot meet the needs of bone grafting due to only empirical operations. Surgical effects, or technical problems of excessive bone harvesting causing additional trauma and increasing surgical risk
