Abstract

The application of the invention discloses a bilateral jaw defect reconstruction pre-operation design method and device based on a database having a three-dimensional configuration. The method and the device are based on the preset database, a healthy head which is mostly accepted by a head to be repaired is selected from the preset database to be used as reference, a bilateral extensively-defected jaw part is reconstructed, and the bilateral extensively-defected jaw lacking uninjured side contrast can also be reconstructed to have appropriate jaw shape and prosthesis 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...
