Prognosis evaluation in dental aesthetic rehabilitations using 2 types of ceramic veneers in a Romanian study group

Abstract

Aims and Objectives. The objectives of this study are the comparaison of survival rate of feldspathic and pressed lithium-disilicate ceramics veneers, survival analysis, failure types, clinical factors that may influence their lifespan in a Romanian study group. Materials and methods The materials used were VITA VM7 (VITA Zahnfabrik, Germany) and E.max (Ivoclar Vivadent AG, Liechtenstein). Patient demographics, treatment and any subsequent failure dates were recorded. 170 patients with 507 veneer-treated teeth were divided into 2 groups: patients with and without therapeutic failures. Results 48 veneers failed. Most failures were fractures (35.36%), followed by debonding and chipping. The most affected veneers in general were the feldspathics (19.9%) compared to lithium disilicate (8.8%) at 10 years. Conclusion Regardless of their superior aesthetics, feldspathic veneers are less mechanically resistant than pressables, but other clinical parameters must also be considered such as the age of the prosthetic rehabilitation or the number of teeth involved. Since study results are consistent with current literature data, Romanian patients can be considered in the international context of veneer treatments.
