Abstract

The invention discloses a periosteum nail position and direction positioning guide plate in GBR and a manufacturing method thereof, which solves the problems in the prior art that the periosteum stability is poor due to inaccurate position when the collagen membrane is fixed by the periosteum nail or the adjacent important anatomical structures are damaged when the periosteum nail is fixed. technical problem. The positioning guide plate includes a base plate and an indicating guide plate. A bolt path is arranged on the base plate, and the indicating guide plate is detachably installed in the bolt path. The production method is mainly to obtain STL data by oral scan before operation, and obtain DICOM data by taking CBCT, fit the two data in the guide plate design software, design the fixed position of the periosteal nail according to the bone grafting range according to the needs, and design the base plate in the guide plate generation software The fixed position of the designed periosteal nail and the direction of needle insertion are indicated by the indicator guide plate. The invention is scientific and reasonable in design, easy to use, and can accurately indicate the position and entry direction of the periosteum nails fixed by the "sausage technique" in GBR, so as to ensure the stability of collagen membrane fixation in GBR, reduce intraoperative complications, and ensure the safety of GBR surgery. Safety and effect.

Description

technical field [0001] The invention belongs to the technical field of medical device structures, and in particular relates to a position and direction positioning guide plate for periosteal nails in GBR and a manufacturing method thereof. Background technique [0002] Over the years, implantology has developed into a field backed by solid clinical evidence and basic research. A prerequisite for successful implant placement is a sufficient amount of bone at the implant recipient site to increase the predictability of implant osseointegration. In partial alveolar bone defects, a more widely used method of bone augmentation is guided bone regeneration. The principle of guided bone regeneration (GBR) is to use a barrier membrane to separate the defective bone from the surrounding soft tissue, creating a protected space for bone regeneration. The protection of the membrane allows the bone defect to be filled with blood vessels and osteoblasts from the marrow cavity and bone su...
