Area of Science:

  • Oral and Maxillofacial Surgery
  • Medical Imaging
  • Computer-Aided Diagnosis

Background:

  • Accurate prediction and patient visualization are crucial for orthognathic surgery success in treating maxillomandibular deformities.

Purpose of the Study:

  • To develop and evaluate a Computer Aided Simulation System for Orthognathic Surgery (CASSOS).
  • To enhance the accuracy, reliability, and patient communication in orthognathic surgery planning.

Main Methods:

  • Development of CASSOS utilizing digital image processing techniques.
  • Automated analysis of frontal cephalograms (71 measurements) and lateral cephalograms (68 measurements).
  • Quantitative surgical simulation for pre-operative prediction and clinical application.
