DENTAL İMPLANTLARIN BİYOMEKANİöİ VE SONLU ELEMANLAR STRES ANALİZ YÖNTEMİ UYGULAMALARI

Abstract

The resistance of the implant aganist the masticatory forces and transferring these forces through prosthetic-implant-bone system so as to provide mechanical balance plays an important role in the long-term success of the implant. The forces that affect implants are effected by the biomechanical properties of the masticatory system and prosthetic materials. The stress which will occur on the transmission pathways teeth, roots and periodontium, prosthetic materials, implant should be determined, so that excess stresses do not form and vital tissues are effected minimally when the masticatory forces of the masticatory muscles are transferred to the jaw bones. Since it is difficult to perform stress analyses of biological materials, such as bone, teeth, the models of these materials should be formed. Finite element stress analysis method is one of the theoretical methods used for evaluating the stresses in the implants. Stress analysis studies of implants will be a guide for the treatment options of the clinician and will increase the rate of the success.

Abstract

ømplantÕn çi÷neme kuvetlerine karúÕ koymasÕ ve bu kuvvetleri protez-implant ve kemik sisteminde mekanik dengeyi sa÷layacak úekilde iletmesi implantÕn uzun dönem baúarÕsÕnda önemli rol oynar. ømplantlara etki eden kuvvetler çi÷neme sisteminin ve protetik materyallerin biyomekanik özelliklerinden etkilenir. Çi÷neme kaslarÕnÕn uyguladÕ÷Õ çi÷neme kuvvetleri çene kemiklerine iletilirken canlÕ dokularÕn fizyolojik limitler içinde etkilenmesi ve aúÕrÕ streslerin oluúmamasÕ için iletim yolarÕnda diúler, kökleri ve periodonsiyumlarÕ, protez materyalleri, implant ortaya çÕkacak stresin belirlenmesi gerekir. Kemik, diú gibi biyolojik malzemelerde stres analizini gerçekleútirmek güç oldu÷undan modelinin hazÕrlanarak analiz edilmesi gerekir. Sonlu elemanlar stres analiz yöntemi, implantlardaki streslerin de÷erlendirilmesinde kullanÕlan teorik yöntemlerden biridir. ømplantlarda uygulanan stres analiz çalÕúmalarÕ, klinsyenin tedavi seçenekleri açÕsÕndan yönlendirici olacak ve uzun dönem baúarÕ oranÕnÕ arÕracaktÕr.
