目的:分析并探讨牙列重度磨耗固定修复完成咬重建后的咀嚼效能,为重度磨耗患者的治疗提供依据。方法:选取16例符合牙列重度磨耗固定修复标准的患者,以固定修复一次性升高咬方法完成咬重建,采用吸光度法比较修复前、修复后3个月、12个月的咀嚼效能定量分析。结果:修复后患者自觉舒适,咀嚼效能均高于修复前,且修复时间越长咀嚼效能恢复得越好,3个时间段两两间比较差异有统计学意义(P<0.05)。结论:在适当选择病例时采用一次性升高咬方法修复牙列重度磨耗,可行而且有效。
OBJECTIVE: To analyze and discuss the masticatory efficiency of the permanent wear and tear of dentition after the completion of bite reconstruction, so as to provide basis for the treatment of patients with severe wear. Methods: Twenty-six patients with fixed and repaired dentition were enrolled in this study. The bite reconstruction was performed by one-time fixed bite repair. The absorbance method was used to compare the masticatory efficacy at 3 months and 12 months after repair Quantitative analysis. Results: After the repair, patients were consciously comfortable and masticatory efficacy were higher than before repair, and the longer the repair time, the better the recovery of chewing performance. The difference between the two time points was statistically significant (P <0.05). Conclusion: It is feasible and effective to repair the severe wear of the dentition by using the method of raising the bite at one time when choosing the appropriate cases.
