Abstract: Rapid Detection Method for Contact Point Displacement by using National Instrument (NI) Vision Builder is a project that help orthodontist to measure improvement of teeth arrangement between pre-treatment and post-treatment according to PAR (Peer Assessment Rating) Index. PAR Index is a summary to score all occlusal anomalies and its deviations from malocclusion to normal occlusion. The difference in scores between the pre and post-treatment cases reflects the degree of improvement and therefore the success of orthodontic interventions. The PAR Index offers uniformity and standardization in assessing the outcome of orthodontic treatment. There are 11 components in PAR Index, the occlusal features recorded are spacing, crowding and impacted teeth. Those occlusal features are identified and measured through teeth’s contact point displacement. National Instrument LabVIEW is using PAR Index and its function as graphical programming language that has its roots in automation control and data acquisition. Its graphical representation, similar to a process flow diagram, was created to provide an intuitive programming environment for. Until today, method to score PAR is by using PAR ruler, which may become quite hard for orthodontist to accurately measure tooth contact point displacement, thus may create error during scoring. It also may take a little more time to score all 11 or some components of each patient. The project is using National Instrument(NI) camera to capture the picture of patient’s teeth casting as the camera will connect to the computer via USB (Universal Serial Bus). We use National Instrument LabVIEW Vision Builder to process the teeth’s picture to get the measurement of the teeth’s displacement as the result will appear on the screen of the computer. The comparison result between few times measurement will appear to reduce the error of the measurement as to get an accurate measurement of teeth displacement. Finally, the goal of this project is to find alternative solutions to advance the measurement of teeth displacement.
