Retrospective evaluation of extended glass‐ceramic ceramic laminate veneers after a mean observational period of 10 years.

Purpose A retrospective evaluation of extended anterior ceramic laminate veneers (EACVs) after a mean observational period of 10 years. Methods: Thirty‐one patients (20 females/11 males) underwent restoration with 101 adhesively luted, heat‐pressed EACVs (maxilla, n = 65; mandible, n = 36). Results: The 10 year survival rate was 91.8% (95% confidence interval [95%‐CI]: 0.87;0.97). Eight ceramic fractures, one biological failure, and one change in treatment plan caused the observed failures. Seventy‐seven of the 101 restorations remained intervention‐free in service (success rate: 78.6% [95%‐CI: 0.70;0.88]). Fourteen interventions were needed (nine recementations, two endodontic treatments, two composite fillings, and one fracture polishing). The jaw position (maxilla/mandible, survival P =.578/success P =.056) had no influence on the clinical performance. EACVs covering large areas of exposed dentin (>50%) were associated with a significantly increased risk (hazard ratio 2.98, P =.019) of needing a clinical intervention (success rate: 68.0% [95%‐CI: 0.52; 0.84]). However, the degree of dentin exposure had no effect on the survival rate (P =.761). Conclusions: After a mean observational period of 10 years, mandibular and maxillary EACVs exhibited survival and success rates that were comparable. Significantly lower success rates were associated with large areas of exposed dentin (>50%). Clinical Significance: Mandibular and maxillary EACV revealed 10‐year survival rates comparable to those published for anterior metal‐ceramic and glass‐ceramic full‐coverage crowns. Precaution should be taken not to expose dentin, and when large areas of dentin are exposed, different conditioning/luting strategies should be used. [ABSTRACT FROM AUTHOR]
