Amaç:
Bu çalışmanın amacı, lityum-disilikat cam-seramik ile tabakalamanın zirkonya destekli kronlardaki marjinal sızıntıya etkisini değerlendirmektir.
Yöntemler:
Yeni çekilmiş 10 adet yirmi yaş dişi akrilik ile doldurulmuş kalıplara kök hizalarından gömüldü. Her bir dişin distal yarısı chamfer basamak (1,2 mm), mezial yarısı ise mini-chamfer (0,6 mm) olacak şekilde prepare edildi. Zirkonya altyapılar bilgisayar destekli tasarım/bilgisayar destekli üretim yöntemiyle hazırlandı. Altyapıların distal yarısı lityum-disilikat cam-seramik ile tabakalandı. Örnekler ısıl döngüye tabi tutulduktan sonra 24 saat süreyle bazik fuksin boyayıcı solüsyona daldırıldı. Her örnekten dört kesit alındı (n=40) ve mikrosızıntı ölçümleri için boya penetrasyonları stereomikroskop altında kadyedildi. Mikrosızıntı değerleri Mann-Whitney U testi ile analiz edildi (α=0,05).
Bulgular:
Her grup için ortalama mikrosızıntı değerleri kaydedildi. Cam-seramik ile tabakalanmış zirkonya grubunda ortalama değerler 1,17±0,69 mm olarak kaydedilirken zirkonya kenar grubunda 1,03±0,74 mm olarak kaydedildi. Gruplar arası fark istatistiksel olarak anlamlı değildir (p=0,102).
Sonuç:
Zirkonya destekli restorasyonlarda lityum-disilikat cam-seramik ile tabakalamanın marjinal sızdırmazlığa katkısı gözlenmemiştir.
Anahtar Kelimeler: Bitim hattı, cam seramik, marjinal mikrosızıntı, zirkonya
