Summary

The goal of this observational study is to learn the accuracy of tooth-bone dual-support osteotomy/location guide plate compared with conventional CAD/CAM interocclusal splints in "surgery-first" orthognathic surgeries.

The main question it aims to answer is:

Does the tooth-bone dual-support osteotomy/location guide plate performed better in accuracy? Does the tooth-bone dual-support osteotomy/location guide plate saved operation time? Participants already underwent orthognathic surgeries.

  • Operation Time

Interventions

PROCEDURE

orthognathic surgery

Orthognathic surgery corrects congenital and acquired dentofacial deformities by surgically repositioning the maxilla, mandible, or chin. It treats severe malocclusion, facial asymmetry, retrognathia, prognathism, and functional issues such as breathing, chewing, and speech difficulties. Performed in conjunction with orthodontic treatment, the surgery uses pre-surgical planning, interocclusal splints, and cutting guides to achieve accurate bony repositioning and stable internal fixation. It improves both facial aesthetics and stomatognathic function, greatly enhancing patients' quality of life.
