Evaluation of the Articulation Following Orthodontic Treatment Utilizing Sam II Articulator and T-scan Occlusal Analyser Before and After Occlusal Adjustment

摘要

The aim of orthodontic treatment has been expanded to include the ideal skeletal and functional relationship. This study was conducted on 9 girls and 11 boys (total 20) between 13-15 years of age. The patients were evaluated 6 months after the completion of retention, with the T-Scan occlusal analyser and semi adjustable SAM II articulator, following non extraction treatment with Straight Wire Roth technique. The number and localisation, the sequence and amount of premature contacts were evaluated qualitative and quantitatively in this study. Result indicates there was a significant increase in the number of contacts after occlusal adjustment with both SAM II articulator and T-scan occlusal analyser. However, there was a significant level of difference between the sensitivity of the two methods ( p<0.001).
