Clinical effect of resilient denture lined prostheses

–The clinical evidence and future tasks–

Abstract

Denture relines using resilient silicone or resilient acrylic material had been implemented in the daily practice for decades. However, this remedy had been controversial and ridiculed among the prosthodontists as “one of the escapes from standard treatment.” However, the rise of global elderly populations resulted in the advent of a super-aging society in several regions; the treatment has been accepted as one of the alternatives treatment for those with limited access or limited time for care. Under such circumstances, Public insurance in Japan has covered the remedy since April 2016; limited to indirect reline for a mandibular denture. In this report will summarize clinical evidence of resilient relined denture on clinical subjective and objective outcomes, both with silicone and acrylic materials. Also, the material characteristics, the clinical techniques are described. The adverse effect of the material is the deterioration: losing elasticity of acrylic, and silicone peeling from denture base. Many clinical has impressions that the status and timing of deterioration differ from patient to patient. Thus, once the patient factors affecting the deterioration of the material are clarified, it will be implemented to make a prior judgment of application to the patient and to predict the deterioration timing. A a proper examination to support the clinical decision as to whether flexible reline denture is adaptable will also be a future issue to be clarified.
