Summary

In patient with skeletal open bite, Dose computer-aided surgery enhances the clinical outcomes and accuracy versus conventional model surgery

Conditions

  • Apertognathia

Interventions

PROCEDURE

Computer guided surgery

Preoperative surgical simulation and immediate postoperative evaluation will be carried out using Multi Slice CT scan.Craniofacial images from 3D computerized tomography (3D-CT scan) can be used to create a 3D model, which can in turn be used for 3D Cephalometry measurements and surgical simulation.The process of 3D-model contains mounting of 3D virtual models in a 3D virtual articulator; and repositioning of 3D virtual models according to the STO then Fabrication of a 3D virtual intermediate surgical wafer; and materialization of the surgical wafer using a stereolithographic technique. The 3D model can produce actual movement of surgical cuts and movement of segments accordingly

PROCEDURE

Conventional model surgery

preparation for orthognathic surgery which involves diagnosis with 2D cephalometric radiograph, face-bow transfer and model surgery on plaster dental cast, and fabrication of intermediate and final occlusal splint.
