Efficiency of simplified versus traditional denture fabrication methods: A systematic review and meta-analysis

Abstract

Statement of problem: 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.

Purpose: The purpose of this systematic review and meta-analysis was to evaluate the efficiency of simplified denture fabrication techniques in comparison with CTs.

Material and methods: 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.

Results: 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).

Conclusions: 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.
