Soft denture liners' effect on the masticatory function in patients wearing complete dentures: A systematic review

J Dent. 2015 Dec;43(12):1403-10. doi: 10.1016/j.jdent.2015.09.005. Epub 2015 Sep 25.


Objectives: To explore the effect of soft denture liners on the masticatory performance and muscle activity of edentulous patients wearing complete dentures, as determined by using objective measurement methods.

Data: Randomized controlled clinical trials and Cross-over studies that evaluated the masticatory capacity and muscle activity in denture wearers with and without soft denture liners were included in this systematic review.

Sources: A comprehensive literature search was performed via electronic databases using the appropriate key words. The last search took place in September 2014.

Study selection: The potentially appropriate articles were identified and evaluated for eligibility through a predefined review process conducted by two examiners. Six out of the 176 identified records were included for quality and systematic assessment.

Conclusions: The observed clinical and methodological diversity determined the narrative approach for the pooling of the findings. According to the studies brought together for the current systematic review, soft denture liners provided denture wearers with increased masticatory function compared to conventional denture base materials. Specifically, the use of long-term silicone liners significantly improved the mastication parameters. The observed intervention effects suggest further studies of higher quality to allow reliable conclusions to be drawn and to strengthen the clinical significance of these materials to patient's functionality.

Clinical significance: Soft denture lining materials have been suggested to address functional problems arising during complete denture function. This study was designed to systematically review the impact of soft liners' use on the masticatory efficiency in denture wearers.
