Orthognathic surgery is a standardized procedure used to improve a patient's facial appearance and to correct maxillary and mandibular deformities resulting from malocclusions, disease or trauma. Bilateral sagittal osteotomy of the mandibular ramus is a technique widely used in orthognathic surgery to correct mandibular deformities. Mandibular advancement is a procedure with a high risk of skeletal recurrence, due to the difference between the proximal and distal bone segments. Objective: To carry out a systematic review of orthognathic surgery in the mandibular advance, focusing on the main challenges and importance. Methods: The present study was followed by a systematic literature review model - PRISMA rules. The quality of the studies was based on the GRADE instrument. The risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: Bilateral sagittal osteotomy is the most used technique in mandibular orthognathic surgery, allowing mandibular movements in the sagittal, vertical and transverse directions, with good results and few complications. However, this technique can cause mandibular advancements above 10 mm, strongly pointing to the placement of a bone graft in order to avoid defects and their complications. Therefore, in orthognathic surgery, bone grafting can accelerate bone formation.
