SUMMARY:

Objective: to evaluate the clinical survival of ceramic laminates in ultra-translucent zirconia, the satisfaction and the impacts of this treatment on the patient's quality of life. Materials and methods: The study was analyzed as a controlled, randomized, double-blind (patient and evaluated) clinical trial with a longitudinal character. The sample studied was 82 ceramic laminates divided into two groups according to the type of material, 39 laminates in lithium disilicate for the control group and 43 in ultra-translucent zirconia for the experimental group. All patients signed an informed consent form. The restorative treatment was carried out by dentists participating in the extension project “Metal-Free Fixed Prostheses”. Data collection was performed by a single examiner in the evaluation periods of 1, 6, 12, 24, 36 and 48 months. The aesthetic satisfaction of each patient was assessed using the visual analog scale (VAS). For the impact on quality of life, a modified OIDP (Oral Impact of Daily Performance) was used. An analysis of clinical longevity was performed using Ryge's modified criteria with a clinical mirror and explorer. The data on the survival of laminates of different materials were plotted using the Kaplan-Meier curve. The Ryge criteria scores and impact on the patient's quality of life were descriptively arranged and the esthetic satisfaction indexes were required with the Mann-Whitney / Friedman U test and Wilcoxon post-test. For statistical analysis, the level of significance was set at 5%. Results: The clinical survival rate was 100% for the laminates of both materials. Only the discoloration marginally criterion obtained  from a classification other than A. The B score was presented by 9 laminates of lithium disilicate and 2 of ultra-translucent zirconia. Aesthetic satisfaction differs statistically significant between the materials for the smile (in T0, T2, T3 and T4), color (T2, T3, and T4), shape (in T1, T3 and T4), size (T2, T3 and T4) and aesthetic result (T1, T2, T3 and T4), with greater satisfaction for the lithium disilicate. There was no negative interference from treatment on the quality of life. Talking and relaxing were activities in which the treatment least interfered. Conclusion: The treatment with laminates made of ultratranslucent zirconia has clinical performance similar to the cases treated with lithium disilicate.
