| Sumario: | ABSTRACT: The aim of this study was to identify the incidence of fractures in single crowns placed in individuals with chronic tooth wear. The sample selection was performed based on the evaluation of 218 patient records rehabilitated with single crowns placed by the same professional from a private clinic. After exclusion criteria, 43 individuals (18 males and 25 females) were included and a total of 112 single crowns distributed in both jaws. Three ceramic systems were evaluated: 34 feldspathic all-ceramic, 38 metal-ceramic with a core in gold electropositive alloy, and 40 In-Ceram Alumina. The intraoral photograph analysis adopted a diagnosis method of tooth wear according to the morphological variations of the teeth. Of the 112 crowns evaluated, 47 were placed in male and 65 in female patients, aged between 21 to 74 years (mean 27.5 years old). The variables gender (p = 0.83), presence of chronic tooth wear (p = 0.91), ceramic system (p = 0.24) and crown location (p = 0.86) did not present a statistically difference. However, the variables pulp vitality (p = 0.04) and survi val time (p = 0.01) presented a statistically significant difference. The evaluated ceramic systems can be considered as alternativ es of restorative material, even in individuals with clinical characteristics suggestive of chronic tooth wear. |
