Various polymeric materials used for attachment systems in overdenture.

Polymeric
Materials		 Structure Advantages Disadvantages Reference
Polyvinylsiloxane (PVS) graphic file with name polymers-13-03248-i001.jpg Presents stable retention and is economical. PVS attachments result in distortion from repeated wear and artificial saliva. [6]
Polymethyl-methacrylate (PMMA) graphic file with name polymers-13-03248-i002.jpg Durable, strong, aesthetic, presents good marginal adaptation, and is economical. Exothermic polymerization, polymerization shrinkage, poor wear resistance, and pulp irritation associated with excess monomers. [7,9]
Plastic resin and Hostaform (polyoxymethylene copolymer) (POM) graphic file with name polymers-13-03248-i003.jpg Elastic, aesthetic, presents good marginal adaptation, and is economical. Minimal wear is seen in plastic matrices with minimal maintenance. [8]
Nylon resin and DuPont Zytel graphic file with name polymers-13-03248-i004.jpg Elastic, aesthetic, presents good marginal adaptation, and is economical. Locator nylon matrices show extensive deformation and require considerable maintenance. [8]
