Comparison of Biodegradable and Titanium Fixation Systems in Mandibular Symphysis or Parasymphysis Solitary Fractures

July 3, 2014 updated by: Louqiang Zhang
The mandible bears a wide range of mechanical load from the contraction of masticatory muscles, and has a significant function in normal chewing movements. Mandibular fractures are the most common maxillofacial fractures, accounting for 40%-71% of all maxillofacial fracture cases with an average of 62%. The etiology of mandibular fractures mainly includes assaults, road traffic accidents (RTAs), falls, and sports injuries. Although a wide variance exists in the reported percentage of anterior mandible fractures, aggregate analysis approximates these fractures at 17% of all mandibular fractures. The rigid internal fixation (RIF) technique has become a common treatment for mandibular fractures, in which titanium plates are used in the operation. Some patients have to remove the titanium plates in a second operation following bone healing because of sequelae, such as stress shielding. Biodegradable plates and screws have been developed to eliminate the problems associated with titanium fixtures. In this study, we aim to compare the clinical performance between biodegradable and titanium fixation systems after 12 months of follow-up in fixation of mandibular symphysis and parasymphysis solitary fractures. We also investigate the stress distributions of biodegradable and titanium fixation systems at mandibular symphysis solitary fracture on the conditions of intercuspal position, labial teeth occlusion, and premolar and molar occlusion using finite element analysis.
