Abstract

The present application discloses a preoperative design method and device for bilateral jaw defect reconstruction based on a three-dimensional shape database. The method and device are based on a preset database, and the healthy skull most acceptable to the skull to be repaired is selected from the preset database. As a reference, the reconstruction of the bilateral large-scale defect jaw, so that the bilateral large-scale defect jaw lacking healthy side controls can also reconstruct the appropriate jaw shape and prosthetic shape.

Description

technical field [0001] The application belongs to the field of medical image generation and application, and in particular relates to a preoperative design method and device for bilateral large-scale jaw defect reconstruction based on a three-dimensional shape database. Background technique [0002] The jawbone is the bone that constitutes the oral cavity, including the maxilla and mandible, and the upper and lower jaws are mainly used as the bone support in the middle and lower part of the face. Jaw defects generally refer to tissue defects of the upper and lower jaws caused by diseases or injuries. Jaw defects often lead to serious appearance defects and functional impairments. Jaw defects and deformities directly lead to great functional and psychological disorders in patients. , Jaw defect and its repair and reconstruction have always been a research hotspot in oral and maxillofacial surgery. [0003] In recent years, digital surgical technology has been increasingly us...
