Embodiment Construction

[0023] The present invention is described in detail below through examples.

[0024] Firstly, CT scanning is performed on the patient's jaw, and then the patient's three-dimensional jaw bone digital model is obtained, and then the virtual mandibular angle osteotomy is performed on the 3D virtual surgery platform, and then the personality is designed according to the shape of the jaw bone, the angle and size of the osteotomy Optimized navigation entities. During this process, the angle and size of the osteotomy were designed according to the hypertrophy of the mandibular angle of the patient, and special attention should be paid to avoiding the course of the inferior alveolar canal in the osteotomy design. The navigation entity is manufactured by rapid prototyping technology, specifically under the control of the computer, according to the CAD (computer-aided design) mathematical model of the object, the prototype is manufactured through the precise accumulation of materials, a...

Abstract

The invention relates to a navigation physical system for precisely cutting the bone of a mandible, in particular to a manufacturing method of a navigation entity for an individuation angle of mandible obesity operation. Aiming at cutting the bone with obese angle of mandible which is a common cranio-jaw-facial operation, the invention realizes the three dimensional accurate cutting bone of the angle of mandible through the operation navigation entity which is formed by the rapid manufacturing technique, improves the operation quality and reduces complications. Compared with the conventional technique, the invention has the advantages that the individuation operation navigation entity is formed by the rapid manufacturing technique, thus guiding the accuracy of cutting bone and bilateral symmetry. In addition, on the basis, the accurate operation navigation technique which is realized by the rapid molding also can be applied to other cranio-jaw-facial plastic operations, thus realizing the digitizing and accuracy of the operation.

Description

【Technical field】 [0001] The invention relates to a navigation entity system for precise mandibular osteotomy, in particular to a manufacturing method of a personalized mandibular angle hypertrophy operation navigation entity. 【Background technique】 [0002] With the improvement of social and economic development and people's living standards, more and more patients require facial contour plastic surgery. Mandibular angle hypertrophy osteotomy is one of the most common facial contour plastic surgery. Using various plastic surgery techniques and craniofacial surgery techniques to carry out facial contour plastic surgery and cosmetic surgery will be the future development trend. In the 21st century, people's new outlook on life is "create a new self, enhance self-confidence, and create a refined life." Therefore, people put forward new requirements and propositions for plastic surgery, and cosmetic surgery tends to be more precise, personalized, and digital. [0003] The comm...
