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.
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.
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)% (24, 25, 14, 15), 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 (11, 12, 21, 22) 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.
At maximum intercuspation: the implants areas including the premolar and anterior teeth were the occlusal force centers; the force concentrated in the area (11, 12, 21, 22) at the protrusion position. The lateral occlusal pattern shows multiformity.
使用T-ScanⅢ咬合分析系统，研究全口4颗种植体修复患者在不同咬合位置的咬合力分布及咬合时间特征。
本研究纳入13例接受全口4颗种植体修复的志愿者。使用T-ScanⅢ咬合分析系统测量患者在牙尖交错位、前伸位和侧方运动位的咬合力分布及时间特征。
牙尖交错位：左右前磨牙承担大部分咬合力，分别为(17.3±3.1)%、(15.8 ± 4.6)%、(15.5 ± 2.2)%和(15.2 ± 5.5)%（24、25、14、15号牙位），包括前磨牙和前牙的种植体区域承担(64.0±6.7)%、(19.2±8.0)%的咬合力。左右侧分别承担(50.5±6.1)%、(4,9.5±6.1)%，无差异。前伸位：区域(11、12、21、22)承担比例为(90.4±27.7)%。咬合时间：0.18(0.11, 0.26)s，分开时间：0.52(0.35, 1.14)s。在左右侧方位置，8例患者为单牙支持式咬合，5例患者为组牙功能式咬合，平均咬合时间为0.20(0.13, 0.34)s，分开时间为1.07(0.58, 1.46)s。
牙尖交错位时，包括前磨牙和前牙的种植体区域是咬合力中心；前伸位时力集中在区域(11、12、21、22)。侧方咬合模式呈现多样性。
