| Abstract | ||
| Aim: The aim of this study was to measure the occlusal parameters of orthodontically treated cases with premolar extraction (experimental group) and compared the result with the measures of non-orthodontic normal occlusion subjects using T-Scan III system. Subjects and methods: The study included 48 participant 32 female and 16 males with age ranging from 17 to 28 years, divided into two groups; experimental group included 24 patients (16 females and 8 males) who finished their orthodontic treatment which included extraction of permanent first premolars teeth and control group which included 27 untreated participants (15 females and 9 males) had class I molar and canine relation with normal anterior and posterior overjet and overbite. T-Scan III occlusal analysis were performed for both groups in centric occlusion. Force distribution on right and left sides and presence of interferences were assessed. Results: The results showed the presence of significant force distribution imbalances and premature contacts in experimental group when measured by the T-Scan technology. These force imbalances and interferences may act as a causative factor in post-orthodontic treatment instability, periodontitis, NCCL, appearance of TMD signs and symptoms and negatively affect the masticatory function. | ||
