Introduction: Practitioner used 2 different plate fixation after reduction of mandibular condyle fracture. This study was to compare sliding plate between conventional 4 hole plate after condyle fracture reduction. Method and materials: A total of 30 patients were operated for condyle fracture. Group was separated two. Control group operated and fixated 4 hole conventional plate (n=13). Experimental group operated and fixated sliding plate (n=17). Approximately 3~6 month later followed up through panorama & reverse townes view X-ray. In these X-ray, we compared angle of non-fracture opposite side condyle between fracture site condyle. Statistical analyzed with Mann-whitney analysis (P<0.05). Results: Observing through Panoramic X-ray fracture site condyle angle and non-fracture site condyle angle’s difference were 2.1 degree at sliding plate and 7.12 degree at 4 hole conventional plate. In reverse towens view X-ray, fracture site condyle angle and non-fracture site condyle angle’s difference is 13.5 degree at sliding plate and 16.5 degree at 4 hole conventional plate. Conclusion: We suggest using sliding plate to reduce condyle fracture. No significant difference measured changing condyle angle after operation between sliding plate and 4 hole conventional plate in panoramic & reverse townes view.
