Abstract: | The mandibular lengthening procedure performed with the use of rigid internal fixation yields more stable results than previously demonstrated when nonrigid fixation is used. Twenty patients with Class II malocclusion who had undergone this procedure were examined retrospectively to assess postoperative skeletal change. The mean postoperative interval was 15.7 months. Although there was individual variability, no significant mean postoperative horizontal change was found, which indicated excellent stability. |
