Conventional techniques (CTs) for complete denture fabrication involve a series of clinical and laboratory steps. A simplification of this process has been advocated, but whether simplified techniques result in acceptable treatment outcomes is unclear.
The purpose of this systematic review and meta-analysis was to evaluate the efficiency of simplified denture fabrication techniques in comparison with CTs.
The standard methodological procedures prescribed by the Cochrane Collaboration for systematic review and meta-analysis were used. An electronic search (MEDLINE through PubMed, Cochrane trial registry, and Scopus) and a manual search up to February 2020 were made to identify studies. Only randomized controlled trials involving edentulous adults requiring complete denture treatment were included.
Nineteen studies met the inclusion criteria. The pooled estimate of the included studies for patient satisfaction at 6 months marginally favored the simplified method of denture fabrication (standardized mean difference=0.02 [95% confidence interval {CI} -0.22 to 0.27]). The pooled estimate of the included studies for clinical time and cost of fabrication favored the simplified method (mean difference=-77.34 [95% CI -122.45 to -32.24] and mean difference=-85.89 [95% CI -170.02 to -1.77] respectively).
Simplified techniques were cost effective and less time consuming than the CT, with no significant difference in patient satisfaction or oral health-related quality of life. The high risk of bias and heterogeneity among studies requires that the results be considered cautiously.
常规技术（CT）用于全口义齿制作涉及一系列临床和实验室步骤。有人主张简化这个过程，但简化技术是否会产生可接受的治疗效果尚不清楚。
本系统评价和荟萃分析的目的是评估简化义齿制作技术与 CT 相比的效率。
使用 Cochrane 协作组织制定的系统评价和荟萃分析标准方法程序。进行了电子搜索（通过 PubMed 的 MEDLINE、 Cochrane 试验注册中心和 Scopus）和手动搜索，截至 2020 年 2 月，以确定研究。仅包括涉及需要全口义齿治疗的无牙颌成年人的随机对照试验。
19 项研究符合纳入标准。纳入研究中患者满意度的汇总估计值略微倾向于简化义齿制作方法（标准化均数差=0.02 [95%置信区间{CI} -0.22 至 0.27]）。纳入研究中临床时间和制作成本的汇总估计值有利于简化方法（平均差值=-77.34 [95%CI -122.45 至 -32.24]和平均差值=-85.89 [95%CI -170.02 至 -1.77]）。
简化技术具有成本效益，并且比 CT 耗时更少，在患者满意度或口腔健康相关生活质量方面没有显著差异。研究中存在高偏倚风险和异质性，因此需要谨慎考虑结果。
