Prosthetic rehabilitation of the upper jaw in patients with expansive bone and soft tissue defects is still a significant problem lack of retantion and stability. Zygomatic implant is an alternative method for these patients. The purpose of this research was to evaluate the stress distribution in the zygomatic bone for three different implant-retained obturator prostheses configuration in a premaxillary with unilateral maxillary defect using a three dimensional finite element stress analysis. 3- dimensional finite element models were constructed based on computed tomograph data. Model 1; one zygomatic implant on defected side, two dental implant on nondefected side, model 2; two dental implant on nondefected side, model 3; one zygomatic implant on each side of the maxilla additionally one dental implant on non defected side. Bar attachments were used as superstructure. Vertical load 150 N was applied in three different ways and the stress distribution were observed and compared. In all loading conditions model 3 when compared another models, shows highest maximum principle stress value on zygomatic bone. Use of zygomatic implant with dental implant in the same part of the maxilla increased the stress values of the zygomatic bone

DENTAL VE ZİGOMATİK İMPLANTLARIN ZİGOMATİK KEMİKTEKİ STRES DAĞILIMINA ETKİSİ

Üst çenede geniş kemik ve doku defektlerine sahip olan hastalarda retansiyon ve stabilite eksikliği protetik rehabilitasyon için ciddi bir problemdir. Bu hastalarda zigomatik implantlar alternatif bir tedavi metodudur. Bu çalışmanın amacı premaksilla ile tek taraflı maksiller defektlerde, 3 farklı şekilde dizayn edilmiş implant destekli obturator protezin zigomatik kemikte yarattığı stresi üç boyutlu sonlu elemanlar stress analiz yöntemiyle değerlendirmektir. Üç boyutlu sonlu eleman modelleri bilgisayarlı tomgrafi verilerine dayandırılarak hazırlandı. 1. model de bir adet zigomatik implant defekt tarafına, iki adet dental implant defekt olmayan tarafa, 2. model de iki adet dental implant defekt olmayan tarafa, 3. model de; defekt olan ve olmayan tarafa birer adet zigomatik implant ilave olarak defekt olmayan tarafa bir adet dental implant yerleştirilmiştir. Üst yapı olarak bar ataçmanlar kullanılmıştır. Dikey yönde 150 N kadar dikey kuvvet üç farklı yolla uygularak gözlenmiş ve karşılaştırma yapılmıştır. Bütün yükleme koşullarında 3.model diğer modeller ile karşılaştırıldığında zigomatik kemikte en yüksek maximum principle stress değerini göstermiştir. Zigomatik implantın dental implant ile maksillanın aynı bölgesinde kullanılması zigomatik kemikte maksimum principle stres değerlerini artırmıştır.
