In vivo occlusal wear of posterior composite restorations. 1991

Memphis State University, Department of Mechanical Engineering, TN 38152.

The available and proposed methods for determining the in vivo occlusal wear values of classes 1 and 2 restorations made of resinfilled composite materials are critically reviewed. A methodology to be used to address the fundamental question of the link between the wear of the in vivo restorations and the relevant mechanical properties of the materials is outlined. For the four commercial formulations of composite materials which are currently "fully acceptable" to the American Dental Association (Estilux Posterior, Ful-Fil, Occlusin, and P-10), analysis of the published clinical wear values versus time data is performed.

D008963	Molar	The most posterior teeth on either side of the jaw, totaling eight in the deciduous dentition (2 on each side, upper and lower), and usually 12 in the permanent dentition (three on each side, upper and lower). They are grinding teeth, having large crowns and broad chewing surfaces. (Jablonski, Dictionary of Dentistry, 1992, p821)	Molars
D011109	Polymethacrylic Acids	Poly-2-methylpropenoic acids. Used in the manufacture of methacrylate resins and plastics in the form of pellets and granules, as absorbent for biological materials and as filters; also as biological membranes and as hydrogens. Synonyms: methylacrylate polymer; poly(methylacrylate); acrylic acid methyl ester polymer.	Methacrylic Acid Polymers,Acid Polymers, Methacrylic,Acids, Polymethacrylic,Polymers, Methacrylic Acid
D011140	Polyurethanes	A group of thermoplastic or thermosetting polymers containing polyisocyanate. They are used as ELASTOMERS, as coatings, as fibers and as foams.	Polyisocyanates,Ostamer,Pellethane,Spandex,Ostamers,Pellethanes,Polyisocyanate,Polyurethane,Spandices

D001641	Bicuspid	One of the eight permanent teeth, two on either side in each jaw, between the canines (CUSPID) and the molars (MOLAR), serving for grinding and crushing food. The upper have two cusps (bicuspid) but the lower have one to three. (Jablonski, Dictionary of Dentistry, 1992, p822)	Premolar,Bicuspids,Premolars

D017438	Bisphenol A-Glycidyl Methacrylate	The reaction product of bisphenol A and glycidyl methacrylate that undergoes polymerization when exposed to ultraviolet light or mixed with a catalyst. It is used as a bond implant material and as the resin component of dental sealants and composite restorative materials.
