Abstract

The invention relates to a construction method of an individualized mandible defect reconstruction guide plate system. According to the invention, a postoperative mandible model is designed and reconstructed according to the mandible ideal reconstruction form; a virtual individualized titanium plate model is designed; mandible positioning nail paths are designed at the corresponding positions of the titanium plate model and the mandible remaining bone section models on the two sides; supply area bone section positioning nail paths are designed at the positions, corresponding to all supply areabone sections, of the titanium plate model, a mandible osteotomy guide plate model is designed, a supply area bone osteotomy shaping guide plate model is designed, and an individualized titanium plate, a mandible osteotomy guide plate and a supply area bone osteotomy shaping guide plate of a solid body are manufactured through 3D printing. The accurate positioning between the individualized guideplate system and the lower jawbone of the patient can be better achieved, the construction process of the optimized guide plate system is easier, more convenient and more efficient, and accurate positioning of matching between remaining bone sections of the lower jawbone, all bone cutting sections of a supply area bone and a titanium plate can be achieved.

Description

technical field

[0001] The invention belongs to the technical field of mandibular defect reconstruction medical devices, in particular to a construction method of an individualized mandibular defect reconstruction guide plate system. Background technique

[0002] The mandible is the only movable bone in the maxillofacial region. It plays a key role in chewing, swallowing and speaking. It is located in the lower third of the face and is closely related to the beauty of the face. Because of many maxillofacial diseases, such as oral cancer, osteoporosis, osteomyelitis and bisphosphonate-related osteonecrosis of the jaw, or because of severe maxillofacial trauma, mandibular defects have seriously affected the function and function of the mandible. Facial morphology, usually requiring serial resection of the mandible. Mandibular defect reconstruction is a complex and time-consuming task for surgeons.

[0003] Continuous reconstruction of the mandible and its soft tissue coverag...
