Kondil Kırıklarında Ortotropik Mandibula Modeli ile Sonlu Eleman Analizleri Kullanılarak Titanyum ve Rezorbe Olabilen Miniplak Sistemlerinin Karşılaştırılması

Abstract

ABSTRACT
 Background: Mandibular fractures comprise a large portion of facial injuries. According to comprehensive series published, 17.5 - 52% of mandibular fractures are condyle fractures. With the development of plate and screw systems, open reduction and internal rigid fixation have also become methods that are accepted. Titanium miniplate and screw systems or resorbable plate and screw systems are used for this purpose. The purpose of this study is to compare the superiorities of titanium plate and screw systems to the superiorities of resorbable plate and screw systems on an orthotropic mandibular model using the finite element analysis (FEA) method.
 Method: With finite element analysis, stress values in bone, plate, and callus and the amount of displacement in plates and fragments with Von Mises forces were examined.
 Result: It was observed that solitary resorbable plates do not generate adequate stability.
 Conclusion: It was observed that titanium plate and screw systems were mechanically superior to resorbable plate and screw systems in the open treatment of mandibular condyle fractures. However, to fully support this opinion, studies with different designs using new resorbable plates are required.
