COMPARISON OF THE CLINICAL ABRASION RESISTANCE OF 6 COMMERCIALLY AVAILABLE DENTURE TEETH

Purpose. Clinical abrasion of denture teeth has certain implications w hen dentures are worn in excess of the average useful lifetime. The pu rpose of this study was to evaluate clinical denture tooth wear over a period of 3 years. Material and Methods. The wear of six commercially available denture teeth (Premierdent, Acrotone, Vitapan, Rxl, Duravit e, and Ivoclar Orthosit) and a seventh combination of teeth was compar ed. Seventy patients with complete dentures were divided into seven gr oups of 10 each to form the study population. Results. There were no s ignificant differences among the commercial denture teeth. Porcelain/V itapan teeth exhibited the highest amount of abrasion. Significant wea r was also measured between the Ivoclar Orthosit and Porcelain/Vitapan teeth.
