Mandible body bone movement kit based on mandible three-dimensional database matching and preparation method thereof

Abstract

The invention relates to a mandible body bone movement kit based on mandible three-dimensional database matching. The mandible body bone movement kit comprises a mandible osteotomy guide plate, a fibula osteotomy guide plate, a transplanted bone positioning guide plate and a titanium plate, the transplanted bone positioning guide plate comprises a C-shaped supporting part used for supporting and positioning a mandible area formed by splicing fibula sections and locking parts arranged on the two sides of the C-shaped supporting part and used for being fixed to the mandible. A positioning groovematched with each fibula section is formed in the upper side face of the C-shaped supporting part, and a nail hole is formed in each locking part. The invention aims to provide the mandible body bonemovement kit based on mandible three-dimensional database matching and a preparation method of the mandible body bone movement kit. The mandible body bone movement kit has the advantages that a three-dimensional model matched with a mandible model database is used as the reference of a missing part of the mandible of a patient, the postoperative facial deformity of the patient can be prevented, and the oral jaw system function and natural appearance of the patient are guaranteed.

Description

technical field [0001] The invention relates to a mandibular body bone transplant kit based on mandibular three-dimensional database matching and a preparation method thereof. Background technique [0002] Large-area jaw defects are mostly caused by severe trauma, infection, or tumor resection. Mild cases lead to facial deformities, and severe cases lose physiological functions such as chewing, language, and swallowing, which greatly affect the patient's oral and jaw system functions and natural appearance. and mental health. Traditional repair methods for jaw defects include autologous free / pedicled bone graft, allogeneic bone graft, non-vascularized bone graft, vascularized bone graft, and distraction osteogenesis. These methods have their own advantages and disadvantages and clinical indications. [0003] The mandibular body of the jaw, as the connecting part of the two sides of the mandible, plays a vital role in the shape of the face. Because of its arc-shaped structu...

AI Technical Summary

Problems solved by technology

[0003] The mandibular body of the jaw, as the connecting part of the two sides of the mandible, plays a vital role in the shape of the face. Because of its arc-shaped structure, after tumor lesion or defect, it is quite different from the original shape. In the conventional design, only Relying on the clinical experience of specialists and engineers to complete the shape design, without objective and quantitative evaluation means, the final clinical effect is not ideal
