Effects Of Cleaning Agents On The Properties Of Two Different Thermoplastic Retainer Materials, Jennifer Brehove
Master's Theses (2009 -)
Objective: There are several different thermoplastic retainer materials and cleaning methods available to fabricate and clean clear retainers. Some studies have investigated the changes in properties of clear retainers after being exposed to different staining agents, varying levels of mechanical strain, and different cleaning agents. However, there are few studies that compare different thermoplastic materials to each other when being subjected to these different types of stresses. The aim of this study is to evaluate the changes in properties of two commonly used thermoplastic retainer materials, polyethylene terephthalate (PETG) and ethylene/propylene (EP), after exposure to different retainer cleaning agents over …
