Mandibular Fractures clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

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

Start date: January 2008
Phase: N/A
Study type: Expanded Access

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.
