Traditional methods for teaching complete denture fabrication are time-consuming, difficult to master, and not used by many general practitioners.
This study compared the efficacy of traditional denture fabrication techniques with a more abbreviated method in a dental school setting.
A retrospective record review of 80 completely edentulous patients treated by predoctoral dental students was completed. Forty patients were treated with traditional denture techniques; the other 40 patients were treated with an abbreviated method. The data abstracted included the number of visits to completion and the number of postinsertion visits and relines required within the first 3 months after delivery. A Wilcoxon rank sum test was performed to determine statistical significance between the groups with regard to number of visits for fabrication and postinsertion adjustments. A test for a difference in proportions by using the normal approximation to the binomial distribution was performed for statistical analysis of the incidence of relines.
The abbreviated denture technique resulted in a statistically significant difference in the number of visits for fabrication (P<.01) and postinsertion adjustments (P<.05.) There was no difference (P=.39) in the number of relines between the 2 groups.
Teaching the abbreviated complete denture technique in an undergraduate dental clinic decreased the number of appointments necessary to complete denture therapy without increasing the number of adjustments or reline procedures.
传统的全口义齿制作教学方法耗时、难以掌握,且许多全科医生并不采用。
本研究在牙科学校环境中比较了传统义齿制作技术与一种更简化方法的效果。
完成了一项对牙科博士前学生治疗的80例无牙颌患者的回顾性记录审查。40例患者采用传统义齿技术治疗;另外40例患者采用简化方法治疗。提取的数据包括完成治疗所需的就诊次数以及交付后前3个月内所需的戴入后就诊次数和重衬次数。进行Wilcoxon秩和检验以确定两组在制作就诊次数和戴入后调整方面的统计学显著性。使用二项分布的正态近似进行比例差异检验,以对重衬发生率进行统计分析。
简化义齿技术在制作就诊次数(P<.01)和戴入后调整次数(P<.05)方面产生了统计学显著差异。两组之间的重衬次数没有差异(P =.39)。
在本科牙科诊所教授简化全口义齿技术可减少完成义齿治疗所需的预约次数,而不会增加调整或重衬程序的次数。
