Simplified Complete Denture: A Systematic Review of the Literature

Abstract

Purpose: Many procedures are used to construct traditional (T) complete dentures; however, a simplified (S) method requiring fewer steps and less time is available. This systematic review intends to summarize the modeling of simplified methods for complete dentures and evaluate the differences between the T method and S method. With this review, we hope to lay the foundation for proposing a standardized fabrication method for "simplified dentures."

Methods: The MEDLINE (via PubMed) and EMBASE databases were searched for articles on simplified complete dentures published in English before April 2014. Eleven articles were included. One was about one-step complete dentures, two were about SET (simplified treatment of edentulous patients), and the others were about the normal simplified method, which includes impression, occlusal registration, and try-in. Seven were randomized controlled clinical trials (RCTs). The time, cost, patient satisfaction, clinical effects, masticatory performance, masticatory ability, and professional evaluation reported in these studies were compared.

Results: We summarized the different techniques of fabricating complete dentures and discussed the RCTs of the normal complete technique. None of the RCTs identified significant differences between the S and T groups in terms of patient ratings for general satisfaction, OHIP-edentulous scale, denture quality, or masticatory ability. At the same time, the T method was significantly more expensive and required more time to complete than the S method.

Conclusions: Current scientific evidence suggests that the S method can replace or partly replace the T method. Moreover, specific rules should be devised to restrict the simplified construction, and detailed research should be conducted.
