COMPUTERIZED P-A ASYMMETRY ANALYSIS AND SURGICAL TREATMENT DESIGN |
| |
| Abstract: | Since the advent of cephalometric radiography, orthodontists and surgeons have fo- cused on the application of lateral x-ray film. However, the frontal (PA) views also contain valuable information for diagnosis and treatment planning of dentofacial deformities. A computerized P-A analysis system has been developed to provide, clinically relevant information about specific locations and amounts of facial asymmetry. Its purpose is com- parative and quantitative, not normative. The clinician can also evaluate surgical plans which are different from the one proposed by this computer system. The surgeon, can cut change and otherwise manipulate the cutouts of the individualized maxilla、mandible and chin to determine the feasibility of alternate treatment plans. This computer aided system can be correlated with lateral cephalometric data to com- plete a three-dimensional facial assessment. |
