Stability after bilateral sagittal split osteotomy advancement surgery with rigid internal fixation: a systematic review.

摘要: PURPOSE: The purpose of this systematic review was to evaluate horizontal relapse and its causes in bilateral sagittal split advancement osteotomy (BSSO) with rigid internal fixation different types. MATERIALS AND METHODS: A search the literature performed databases PubMed, Ovid, Cochrane Library, Google Scholar Beta. From 488 articles identified, 24 were finally included. Six studies prospective, 18 retrospective. range postoperative study records 6 months 12.7 years. RESULTS: short-term for bicortical screws between 1.5% 32.7%, miniplates 18.0%, bioresorbable 10.4% 17.4%, at point B. long-term 2.0% 50.3%, 8.9%, CONCLUSIONS: BSSO mandibular is a good treatment option skeletal Class II, but seems less stable than setback short long terms. Bicortical titanium, stainless steel, or material show little difference regarding stability compared term. greater number larger rates evident patients treated instead miniplates. etiology multifactorial, involving proper seating condyles, amount advancement, soft tissue muscles, plane angle, remaining growth remodeling, skill surgeon, preoperative age. Patients low angle have increased vertical relapse, whereas high more relapse. Advancements 7 mm predispose To obtain reliable scientific evidence, further research into should exclude additional surgery, ie, genioplasty maxillary include prospective randomized clinical trial design correlation statistics.
