Abstract

Aim: Bonded, occlusal overlays constitute a conservative alternative to traditional complete coverage crowns. The aim of this study is to evaluate the selection of the appropriate restoration design, and its influence on the periodontal health, marginal discoloration, secondary caries, fracture stregth and retention which may affect the longevity of the restoration. Materials and methods : Ten patients were included and two different restoration designs 5 complete coverage crowns, 5 modified occlusal overlays was used. Restorations were fabricated by milling 3M Lava Ultimate blocs with Cerec CAD/CAM system. 10 restorations were evaluated according to modified USPHS United States Public Health Service Criteria criteria in 1, 3 and 6 months periods. Results: 1 month after the cementation of the restorations, no signifuture differences was observed between the two restoration types. After 3 months, periodontal problems began to occure in the complete coverage crowns. After 6 months, the complete coverage crowns showed marginal discoloration. No decementation, fracture and secondary caries were occured in two types of the restorations. Conclusions : Within the limitations of this study, it can be concluded that, the clinical performances of the occlusal overlays were more satisfactory than the complete coverage crowns

Okluzal overley ve tam kronların klinik olarak değerlendirilmesi

Abstract

Amaç: Adeziv bağlanan okluzal overley restorasyonlar, tam kron restorasyonlara alternatif konservatif bir tedavi seçeneği oluşturur. Bu çalışmanın amacı, uygun restorasyon tasarımı seçimine bağlı olarak ve bu seçimin restorasyonun uzun süreli kullanımını etkileyen periodontal sağlık, marjinal renklenme, sekonder çürük, restorasyonda kırık ve retansiyon üzerindeki etkilerini değerlendirmektir. Gereç ve Yöntem: 10 hasta çalışmaya dahil edilmiştir ve iki farklı restorasyon tasarımı 5 tam kron, 5 modifiye okluzal overley kullanılmıştır. Restorasyonlar Cerec CAD/CAM sistemi kullanılarak 3M Lava Ultimate bloklardan üretilmiştir. 10 üye restorasyon modifiye USPHS United States PublicHealth Service Criteria kriterleri kullanılarak 1., 3. ve 6. aylarda değerlendirilmiştir. Bulgular: Restorasyonların simantasyonunu takiben 1 ay sonra iki restorasyon tipi arasında belirgin bir fark gözlenmemiştir. 3 aydan sonra tam kron restorasyonlarda periodontal problemler görülmeye başlamıştır. 6 aydan sonra ise tam kron restorasyonlarda marjinal renklenme gözlenmiştir. Her iki restorasyon tipinde de desimantasyon, restorasyonda kırık ve sekonder çürük gözlenmemiştir. Sonuç: Bu çalışmanın sınırları içerisinde okluzal overley restorasyonların klinik performansı tam kron restorasyonlara göre daha tatmin edici olduğu düşünülebilmektedir
