SURVIVAL RATE OF FELDSPATHIC CERAMIC VENEERS VERSUS PRESSED CERAMIC VENEERS

Objectives. The present study aims at evaluating the survival rates differencies of feldspathic and pressed (lithium disilicate) veneers as well as the most frequent types of failure. Material and method. 404 venners (262 feldspathic and 142 pressed) were comprized in the study and 5 types of failures were defined. Results. 9.41% of the total veneers have suffered one form of failure. From the total number of 38 failures, 28 were feldspathic and 10 were pressed. The most frequent incidents were due to the traumatic occlusion. The survival rate was 97% at 1 year, 96.18% at 2 years and 93.54% at 5 years. Conclusions. The statistic results revealed that the ceramic material influenced the survival rate. For a better assessment, it is recommended the study of equal groups in both materials and the same amount of time of evaluation, to exclude analysis errors.
