Mandibular kondil kırıklarının fiksasyonunda uygulanan titanyum mini plak ve vida sistemleri ile rezorbe olabilen mini plak ve vida sistemlerinin sonlu eleman analizi ve biyomekanik yöntemleri ile karşılaştırılması
Özet
The aim of this study is to compare the titanium and resorbable plate screw sytems used for the fixation of mandibular condylar fractures using finite element analyses and convetional biomechanical tests.Mandibular modelling was done using computurised tomography datas. Also plate and screws were created using 3 dimensional modelling software. Then these created plate and screws were placed around the fracture line. After applying masticatory forces the biomechanical properties of the titanium plate and screws, resorbable plate and screws and bone around the fracture line were evaluated.20 synthetic polyurethan models were used for convetional biomechanical tests. Fracture lines were created for each model and 10 titanium plates were adepted and the fragments were fixed using titanium screws. Same procedures were applied for resorbable plate screw systems. masticatory forces were apllied to the model and the biomechanical properties of the titanium plate and screws, resorbable plate and screws and bone around the fracture line were evaluated.In conclusion resorbable plate systems is not still an alternative for the fixation of unilateral condylar fractures. Also finite element analyses provides researchers more detailed evaluation and detailed infromation.
