Abstract (2. Language): 
The purpose of this study was to evaluate the fracture resistance of rennforced acryiic denture base, using three different palatal shapes. Maxiilary denture bases having three types of palatal vault shapes -shallow, medium and deep- were used in this study. The reinforced materials used were the round metal wire-diametered in 1.50 mm, semi-rounded metal wire -thickened 1.50x0.75 mm- and the stainless steel mesh (70mmx2.5mmx2.5mm). A total of 132 acryiic denture bases were prepared with the conventional method from heat-cured acrylic resin (Meiodent; Heraeus Kulzer Ltd). They were stored in distilled water at 37±10C for 48 hours before testing. After storage, the fracture force was measured by using Haunsfield pull-compress machine at a cross-head speed of 5 mm/min. Standard deviations and means were calculated. Univariate variance analysis was used for statistical assessment. Duncan multiple-comparison test was applied. In this study, fracture resistances of denture bases in shallow shaped (79.3 N) were found lower than those of the medium (86.8 N) and deep shaped ones (81.2 N). It was determined that the type of the palatal shapes and reinforcement would significantly affect fracture resistance.

Bu çalışma, metal He güçlendirilmiş ve güçlendirilmemiş olarak farklı damak şekline sahip modellerde hazırlanan akriiik kaide plaklarının kırılma kuvvet/erini ince/emek amacı ile yapıldı. Üç farkı damak şekinne sahip modeller (sığ, orta ve derin) çalışmada kul/anıldı. Her bir damak şeklinden 16 tane olmak üzere, toplam 48 model sert alçıdan elde edildi. 2.80 mm kalınıığında mum alçı modeller üzerine yerleştirildi. Modeller muflaya alındıktan sonra kuvvetlendirilmiş veya kuvvetlendirilmemiş o/arak üreticinin önerisi doğruttusunda hazrraanan akriiik reznn l/e akr/lik kaide plağına dönüştürüldü. Hounsfield çekme-sıkıştrrma cihazında 5 mm/min başhk hızı ile kırı/ma dayanıklılıkları tespit edildi. İstatistiksel değerlendirme için varyans anaiizi kul/anıldı. Ortalama ve standart sapmalar hesap/andı. Duncan çoklu karşı/aştırma testi uygu/andı. Kırı/ma mukavemetinin; düz damaklarda (82.31 N), orta (87.75 N) ve dernn oaanaardan (88.13N) daha düşük olduğu görüldü. Damak deriniiği ve takviyenin önemli ölçüde kırı/ma kuvvetini etkilediği istatistiksel o/arak saptandı.
