Aim and objective: The aim of this review was to evaluate the efficacy of the masticatory performance of the complete dentures. The objective of this review was to evaluate scientific evidence of the impact of simplified impression technique versus conventional impression technique on masticatory performance of complete denture wearers.
Materials and methods: Three electronic databases (PubMed, Web of Science, and Cochrane library) were searched until 30th October 2020, without any publication year limit. Manual search of the references cited in the included studies and gray literature were also included. Randomized clinical trials that assessed objectively the masticatory performance between complete dentures fabricated from two different impression techniques were included.
Results: A total of 398 studies were obtained through search in 3 electronic databases (PubMed- 229, Web of Science- 155, and Cochrane library- 14). Qualities of randomized controlled clinical trials were assessed by Cochrane's tool for Systematic Reviews of Interventions. Heterogeneity of data and measurement methods between the studies limited the scope of their meta-analysis. Nine studies remained after the removal of duplicates and screening of titles and abstracts. Applying eligibility criteria remainder three randomized controlled clinical trials were included after removing six studies.
Conclusion: No significant difference was found objectively in masticatory performance of individuals wearing complete dentures fabricated either by simplified impression technique or conventional impression technique.
