Abstract :Amaç: Bu çalışmanın amacı, farklı basamak tipi ve koniklik açısının lityum disilikat cam seramiklerin baskı dayanımına olan etkisini değerlendirmektir. Gereç ve Yöntem: Baskı dayanıklılığı testi için farklı basamak tipi insert ignore into journalissuearticles values(chamfer ve shoulder); ve 2 farklı koniklik açısında insert ignore into journalissuearticles values(6° ve 12°); 40 adet metal day hazırlandı. Metal day üzerine IPS e.max Press örnekler simante edildikten sonra baskı testi uygulandı. Bulgular: Veriler Varyans analizi insert ignore into journalissuearticles values(ANOVA); ile değerlendirildi ve sonuçlar istatistiksel olarak önemli bulunmuştur insert ignore into journalissuearticles values(p=0.00);. 12° konik açılı shoulder basa- mak tipli örnekler en yüksek insert ignore into journalissuearticles values(3534.40±159.50 MPa);, 6° konik açılı chamfer örnekler ise en düşük insert ignore into journalissuearticles values(2281.28± 171.31 MPa); baskı dayanımı değerlerini göstermiştir. Sonuç: Koniklik açısı ve basamak tipinin farklı olması IPS e.max Press\` in baskı dayanımını etkilemektedir. Anahtar Kelimeler: Lityum disilikat cam seramik, baskı dayanımı, basamak, koniklik açısı EVALUATION OF THE EFFECT OF MARGINAL DESIGN AND TAPER ANGLE ON THE FRACTURE STRENGTH OF LITHIUM DISILICATE GLASS CERAMICS ABSTRACT Aim: The aim of this study was to evaluate the effect of different margin designs and taper angel on fracture strength of lithium disilicate glass ceramics. Materials and Methods: A total of 40 metal die samples with different margin designs insert ignore into journalissuearticles values(shoulder and chamfer); and two different taper angel insert ignore into journalissuearticles values(6° ve 12°); were prepared for fracture strength test. Fracture force was applied after IPS e.max Press samples was cemented to the metal dies. Results: The data were analyzed with ANOVA and the results were statistically significant insert ignore into journalissuearticles values(p=0.00);.. The samples with 12° taper angle and shoulder margin design showed the highest fracture strength insert ignore into journalissuearticles values(3534.40±159.50 MPa);, the samples with 6° taper angle and chamfer margin design showed the lowest fracture strength insert ignore into journalissuearticles values(2281.28±171.31 MPa);. Conclusion: Different taper angle and margin design effect the fracture strength of IPS e.max Press. Keywords: Lithium disilicate glass ceramic, fracture strength, margin design, taper angle
Keywords : Lityum disilikat cam seramik, baskı dayanımı, basamak
