Abstract:
Objective To investigate the occlusal force distribution and the characteristics of the occlusion time of patients with All-on-4 rehabilitation at different occlusion position using T-Scan Ⅲ occlusal analysis system.Methods Thirteen volunteers with All-on-4 rehabilitation were included in this study.T-Scan Ⅲ occlusal analysis system was used to measure the occlusal force distribution and the time character of the patients at intercuspal position,protrusive position,and lateral excursive position.Results Maximum intercuspation:the left and right premolars took most of the occlusal force,namely (17.3±3.1)%,(15.8±4.6)%,(15.5±2.2)% and (15.2±5.5)%(4),(5),(4),(5),the implants areas including the premolar and anterior teeth took (64.0±6.7)%,(19.2±8.0)% of occlusal force.The left and right sides took the respective percentages of (50.5±6.1)%,(49.5±6.1)%,and there was no difference.Protrusion position:the region (21)(12) commitment to take the percentage of (90.4±27.7)%.Occlusion time:0.18(0.11,0.26) s,disclusion time:0.52 (0.35,1.14) s.At the left and right lateral position,8 patients were single teeth-supported occlusion,5 patients were group fuctional occlusion,the average occlusion time was 0.20(0.13,0.34) s,and DT was 1.07 (0.58,1.46) s.Conclusions At maximum intercuspation:the implants areas including the premolar and anterior teeth were the occlusal force centers;the force concentrated in the area ((21)(12)) at the protrusion position.The lateral occlusal pattern shows multiformity.
