目的:探讨全瓷嵌体修复单颗倾斜低后牙后提高咀嚼效率、平衡力的临床效果。方法:选择5例后牙倾斜低患者参与此项研究,用吸光度法测定患者嵌体修复前后的咀嚼效率并用T-ScanⅢ咬合力计测量两侧力的平衡状况。结果:嵌体修复前后患侧咀嚼效能吸光度值分别为0.451±0.158和0.574±0.202,前后比较,差异有统计学意义(P<0.05);两侧力差值修复前(-5.9400±1.623 0)%与修复后(-2.346 6±1.468 3)%,二者比较差异有统计学意义(P<0.05);力中心点(COF)距中线的垂直距离修复前为(-3.426 7±1.692 9)mm,修复后为(-0.733 3±0.365 1)mm,差异有统计学意义(P<0.05)。结论:全瓷嵌体修复后能提高单颗倾斜低 后牙的咀嚼效率,使两侧力在左右向更趋于平衡,从而发挥正常的咀嚼功能。
OBJECTIVE: To investigate the clinical effect of all-ceramic inlay to improve masticatory efficiency and balance after single tilted posterior teeth. Methods: Five patients with posterior teeth of oblique hips were enrolled in this study. The masticatory efficiency before and after intima restoration was measured by absorbance method and the balance of lateral force was measured by T-Scan Ⅲ bite force meter. Results: Before and after intima restoration, the masticatory efficacy absorbance values of the affected side were 0.451 ± 0.158 and 0.574 ± 0.202, respectively, with significant difference before and after treatment (P <0.05); before the difference between the two sides was corrected (-5.9400 ± 1.623 0 ) And% (-2.346 6 ± 1.468 3)%, respectively. The difference between the two groups was statistically significant (P <0.05). The vertical distance from the central line of COF to central line was (-3.426 7 ± 1.692 9) mm and (-0.733 3 ± 0.365 1) mm after repair, the difference was statistically significant (P <0.05). CONCLUSION: All-ceramic inlay restoration can improve the masticatory efficiency of a single tilted lower lobe and balance the right and left lobe forces on both sides so as to exert normal masticatory function.
