Searches for biocompatible restorative materials with better clinical properties, longevity and esthetics
have resulted in the development of several ceramic types. The aim of this study was to evaluate the
performance of Ceramco inlays and onlays over 40 months.
Thirty ceramic indirect restorations
were placed in 10 patients and all were adhesively cemented with a dual resin cement. The clinical
performance was evaluated by a calibrated examiner who attributed scores adapted from the Cvar and
Ryge criteria: color, marginal adaptation, abrasion, caries recurrence, fracture and postoperative pain. These
assessments were performed after cementation of the restorations (T0=baseline) and after 4 periods: T1 (10
months), T2 (20 months), T3 (30 months) and T4 (40 months). Photographs were made in T0 and T4 to illustrate
the general condition of each restoration. Data were analyzed statistically by Kruskal-Wallis H statistics (p=0.05)
and results were presented using percentage values.
Clinical evaluation revealed no color alteration
or abrasion (100%); a success rate of 96.7% for caries, fractures and postoperative pain; and 76.7% of failure
for marginal adaptation.
The ceramic restorations did not show alterations that could result
in their replacement, although there was a moderate failure in the marginal adaptation
