Abstract

Aim: The purpose of this study was in-vitro evaluation of marginal adaptation and fracture strength of zirconia based ceramic crowns prepared in five different ways. Material and Methods: 30 stainless steel dies representing a molar crown were formed. 5 groups containig 6 dies each were formed. Groups were as follows: group 1. In-Ceram Zirconia prepared by slipcasting, group 2. Wol-Ceram prepared by electrodepositing, group 3. ZirkonZahn prepared by manual design and manufacturing, group 4. Cercon prepared by manuel design and digital manufacturing, group5. Everest prepared by digital design and digital manufacturing. All the crowns were evaluated for marginal adaptation before and after cementation by using stereo microscope. Data were statistically evaluated by Student t test. Fracture strengths of crowns were measured by a universal testing machine at a cross-head speed of 5mm/minute after thermo-cycling. One way ANOVA test were used to evaluate the data. Results: Everest group showed the lowest marginal adaptation values before (24,80 ± 4,77 µ) and after cementation (41,86 ± 5,41 µ) (p

Özet

Amaç: Bu çalışmanın amacı 5 farklı yöntemle hazırlanan zirkonya altyapılı porselen kuronların marjinal uyum ve kırılmadirençlerini in vitro olarak değerlendirmektir.Gereç ve yöntem: Prepare edilmiş molar dişi temsilen 30 adet paslanmaz çelik güdük her grupta 6 adet olacak şekilde 5 grubaayrıldı.. 1. grup slip-casting yöntemi ile hazırlanan In-Ceram Zirconia, 2. grup electrodepositing yöntemi ile hazırlanan WolCeram, 3. grup manuel dizayn ve manuel kopya üretim ile hazırlanan ZirkonZahn, 4. grup manuel dizayn ve dijital üretim ilehazırlanan Cercon ve 5. grup dijital dizayn ve dijital üretim ile hazırlanan Everest örneklerden oluşturuldu. Kuronlar simanteedilmeden önce ve sonra optik mikroskop ile marjinal uyum açısından değerlendirildi. Verilerin değerlendirilmesinde Student ttesti uygulandı.Simantasyon sonrası termal siklus uygulanan kuronların kırılma dirençleri, 0.5 mm/dakika başlık hızına ayarlı universal testcihazında ölçüldü. Veriler tek yönlü varyans analizi (ANOVA) ile değerlendirildi.Bulgular: Everest grubuna ait örnekler marjinal uyum açısından hem simantasyon öncesi (24,80 ± 4,77 µ) hem desimantasyon sonrası (41,86 ± 5,41 µ) en düşük değerleri verdi (p
