Adhesively luted silica-based veneers and crowns can yield clinical long-term success even on structurally compromised teeth, according to a study presented at the American Association for Dental Research (AADR) annual meeting in Washington, DC.
The study authors, from the University of Tübingen and Wiesbaden, Germany, conducted a long-term follow-up to evaluate the clinical performance of silica-based all-ceramic partial veneers and full-coverage crowns in patients suffering from amelogenesis imperfecta (AI).
They looked at six AI patients between the ages of 12 to 26. Subjects were treated with 110 minimally invasively prepared veneers and crowns. All restorations were adhesively luted using a resin luting composite. The patients were then followed by clinical examinations.
Among the study findings:
- During a median observation time of 7.5 years, six units were replaced due to failure by fracture.
- Three units underwent complication by minor crack.
- Among 101 units free of complication, 81 were rated excellent and 20 were rated acceptable mainly due to slight marginal discolorations.
