Abstract
Statement of problems: There are only a few studies available that deal with the clinical behavior of ceromer systems as potential substitutes for metal-ceramic crowns.
Purpose: This prospective study was initiated to evaluate the clinical performance of 35 Sculpture crowns after 2 years in service.
Material and methods: Thirty five Sculpture crowns were placed for 20 patients (7 men and 13 women). All patients were treated by the same dentist, and all restorations were fabricated by the same dental laboratory. Crown placement involved both the anterior and posterior regions of the dental arches. Patients were evaluated by two examiner at baseline, 12, and 24 months using the CDA quality assessment system in addition to periodontal criteria.
Results: Of 34 crowns remaining in the study after 2 years, only one crown had experienced a marginal fracture. The crown was replaced as a result of recurrent caries. All remaining crowns were ranked as either excellent or acceptable for surface and color, anatomic form, and marginal integrity.
Conclusion: The 2-year clinical observations and ranking with the CDA quality assessment criteria supported the conclusion that Sculpture crowns may be used in substitutes for metal- ceramic crowns.
