Application of computer technology in complex facial deformities
- 1. Application of computer technology in complex facial deformities Dr. Emmanuel Azariah MDS FIBOMS FIBCSOMS Associate Professor, Faculty of Dental Sciences, Sri Ramachandra Institute of Higher Education and Research
- 2. Maxillofacial Imaging • now any MDCT data set can be converted to a 3D image • the pixels in between the two slices is calculated by the software algorithm. • so thinner the slice less calculation or computers imagination • less than 1mm is ideal • images should be acquired in DICOM (Digital Imaging and Communications in Medicine)
- 3. Complex Facial Deformities • Asymmetries • condylar problems • syndromes
- 4. Computer Aided Surgery - CAS • Virtual Models - Physical Models • Surgical Simulation - creating a treatment plan • Creating Splints, cutting Guides, implant designs • Navigational Surgery
- 5. CFD - Unilateral Ankylosis case of Unilateral Ankylosis Ankylosis release twice No reconstruction of Ramus condyle Unit at surgery complaints of Facial Symmetry NO LEFT RAMUS CONDYLE UNIT
- 8. Treatment Plan • Lefort I , BSSRO, Genioplasty • ? Left Proximal Segment control without Condyle reconstruction. • Patient weary to extensive procedures • Plan B

- 13. Treatment Plan Cutting Guides for resection of Ankylosis cutting guides for osteotomies Custom Joint Prosthesis Screw lengths for various regions
- 15. Tooth Supported Splints or Bone Supported • CT Data does not give accurate tooth morphology • additional data of dentition • IO Scans, Dental Models scanned. • additional armamentarium • additional cost • same errors possible.
