PEER ASSESSMENT RATING (PAR) INDEX CALCULATION ON 2D DENTAL MODEL IMAGE FOR OVER JET, OPEN BITE, AND TEETH SEGMENTATION ON OCCLUSION SURFACE
Abstract: Malocclusion is a
clinical symptom, in which the teeth of maxilla and mandible are not located at
the proper location. If malocclusion left untreated, it can lead to
complications in the digestive system, headache, and periodontal disease
disorders. Malocclusion problems involving abnormalities of teeth, bones, and
muscles around the jaw are obligation of orthodontic specialists to treat them.
The treatments can be varying based on the type of malocclusion, including
tooth extraction and tooth braces. To know certain degree of malocclusion
experienced by the patient, an assessment method called Peer Assessment Rating
(PAR) Index is usually used by the specialist. To help the works of orthodontic
specialists in Indonesia, a new automated calculation system based on 2D image
of tooth model for PAR Index is being developed. In this paper, the calculation
system for over-jet, open-bite, and teeth segmentation is developed. The result
of the developed system is then compared with manual assessment done by
orthodontic specialist, in order to verify the accuracy of the system.
