HOPPEN, Lis Regina Carneiro et al. Aesthetic comparison between crowns made with Cubo and metal-ceramic systems. RSBO (Online) []. 2010, 7, 2, pp. 146-153. ISSN 1984-5685.

INTRODUCTION AND OBJECTIVE: The objective of this study was to verify the influence of different materials used in the construction of infrastructures on the aesthetic result of restorations with ceramic coating. MATERIAL AND METHODS: A patient that needed a single prosthetic crown on the maxillary central incisors was selected for treatment, one in the right maxillary central incisor (11) and another in the dental implant (21). Metal-free (Cubo system) and metal-ceramic (MC) crowns were made for each tooth and submitted to blind review by 11 dentists, who answered a questionnaire about ratios of opacity and translucency of the crowns in the oral cavity of the patient, where each answer corresponded to one score. Data was submitted to Wilcoxon test (a = 0.05). RESULTS: There was no significant statistical difference between the metal-ceramic and Cubo system crowns (11: p = 0.107; 21: p = 0.739). The analysis of the scores also showed that for the same type of infrastructure there was no significant statistical difference between 11 and 21 (Cubo: p = 0.206; MC: p = 0.102). CONCLUSION: Within the limits of this study, it was concluded that, according to the visual perception of the evaluators, prosthetic crowns made with metal infrastructure and with ceramic infrastructure showed to be aesthetically similar and satisfactory.
