Effect of powder air polishing and ultrasonic scaling on the marginal and internal interface (tooth-veneer) of ceramic veneers: an in vitro study

HIGHLIGHTS

• What: Objectives This study investigated the influence of prophylactic treatments and thermocycling on the marginal and internal veneering interface (tooth-veneer) as well as on the surface texture of ceramic veneers. For the analysis of the marginal interface, an F-filter (0.25 mm) was applied. Similar to the present study, Unterschütz et_al were able to show that both ultrasonic scaling and powder air polishing result in a deepening of the marginal gap by examining veneers made of polymer-infiltrated ceramic network material and resin-based composite . It should be noted that the study design includes . . .
