Occlusal results after open or closed treatment of fractures of the mandibular condylar process

Purpose: This study compared the occlusal relationships after open or close d treatment for fractures of the mandibular condylar process. Patients and Methods: A total of 137 patients with unilateral fractures of the mandibular condylar process (neck or subcondylar), 77 treated closed an d 65 treated open, were included in this study. Standardized occlusal photo graphs obtained at several postsurgical time intervals were examined and sc ored by a surgeon and an orthodontist. Standard statistical methods were us ed to assess differences between groups. Results: Patients treated by closed techniques had a significantly greater percentage of malocclusion compared with patients treated by open reduction , in spite of the fact that the initial displacement of the fractures was g reater in patients treated by open reduction. Conclusions: Based on this stud!, more consistent occlusal results call be expected when fractures of the mandibular condylar process are treated by o pen reduction.
