[Characteristics of wearing resistance of materials for repair of masticatory teeth].
Wear resistance parameters were evaluated for 5 materials used for masticatory teeth filling. The study was carried out on an Uism-1 device for evaluation of abrasion resistance of dental materials by the friction method during circular movement of a premolar (removed for orthodontic indications) along the surface of reference material. Similar abrasion resistance in the material-tooth pair was detected for 4 materials: Herculite XRV (Kerr-Sybron), Unirest (Stomadent), Dyract AP (Dentsply/De Trey), and Tytin amalgams (S.S. White); the parameters of wear differed. The highest wear of material paralleled by high tooth abrasion were detected for Filtek P-60 (3M/Dental) material.
