Abstract

Introduction: Flexible denture is an alternative treatment modality for removable partial denture (RPD) that aid the retention by ensuring seal around the entire border of the denture. It is also referred as hypoallergenic denture especially for those who are allergic towards conventional acrylic denture which is the poly-methylmethacrylate monomer (PMMA) and metal (cobalt chromium). The flexible material exhibits lower flexural modulus than conventional type of baseplate material denture that makes it nearly unbreakable. Nowadays, there are a handful of different flexible materials in the dental market for the general dental practitioners to choose but somehow the studies on the properties of these different types of flexible materials are sparse.

Objectives: The present study is to study the development of the flexible materials, the different type of flexible materials and their physical properties.

Methods: From the limited article journals available, the authors have summarized the history, development and constituents of different type of flexible materials used in fabricating denture. Besides that, the authors also discussed about the indications, contraindications, advantages and disadvantages of the materials in denture constructions based on all the published researches available on this topic using published materials available in the dental library, University of Malaya and the databases (Science Direct, PubMed).

Conclusion: Each flexible material has its pros and cons. Therefore, careful selection of material and understanding of the flexible dentures’ indications and contraindications are utmost importance to make sure the best treatment outcome. Hence, patients’ best interest and quality of life can be upheld.
