Abstract

The invention discloses a periosteum nail position and direction positioning guide plate in a GBR and a manufacturing method thereof. The technical problem that in the prior art, when a periosteum nail is used for fixing a collagen membrane, the position is not accurate, so that the stability of the periosteum is poor, or when the periosteum nail is fixed, an adjacent important anatomical structure is damaged is solved. The positioning guide plate comprises a base plate and an indicating guide plate, wherein a bolt channel is formed in the base plate, and the indicating guide plate is detachably installed in the bolt channel. The manufacturing method mainly comprises the steps that STL data is obtained through preoperative mouth scanning, CBCT is shot to obtain DICOM data, the two pieces of data are fitted in guide plate design software, the periosteum nail fixing position is designed according to the bone grafting range as needed, and the base plate and the indicating guide plate aredesigned in guide plate generation software to indicate the designed periosteum nail fixing position and the needle inserting direction. The periosteum nail position and direction positioning guide plate is scientific and reasonable in design and convenient to use, the periosteum nail position and the entering direction of the collagen membrane fixed through the sausage technology in the GBR can be accurately indicated, the fixing stability of the collagen membrane in the GBR is guaranteed, intraoperative complications are reduced, and the safety and effect of the GBR operation are guaranteed.

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...
