Abstract (2. Language):
In the present study, the effects of two different positioning of" wa\ patterns in metal rings on marginal adaptation were investigated. Thirty wax bridge patterns were prepared on a metal mould, and they were invested to that the long axes half of the wax pattens were parallel to the long axes of the rings and those of others perpendicular. The castings were obtained by setting, hygroscopic, and termal expansion techniques. The castings were adapted to metal mould, and their photographs were taken by means of light microscope. The marginal gap of each cast was measured on its photograph. As a conclusion, it has been determined that the placement position of wax pattern has no effect on the marginal adaptation of the cast.

Abstract (Original Language):
Bu araştırmada mum modelin döküm manşetine yerleştirilme şeklinin marjinal adaptasyona etkisi incelenmiştir. Metalden yapılmış modeller üzerinde hazırlanmış mum köpril örnekleri manşet aksına paralel ve dik pozisyonda olmak üzere revetmanlanmış; sertleşme, higroskopik ve termal genleşme yöntemleri uygulanarak dökümler elde edilmiştir. Elde edilen döküm örnekler modele adapte edildikten sonra ışık mikroskobu altında marjinal bölgenin, fotoğrafları çekilerek, fotoğraflar üzerinde marjinal aralık ölçümleri yapılmıştır. İstatistiksel analizler sonunda mum modelin manşete yerleştirilme şeklinin marjinal adaptasyona etkisinin olmadığı belirlenmiştir,
