Distraction osteogenesis (DO) is a surgical procedure that uses a distractor through an osteotomy site, by applying mechanical stretching forces to produce new organization. These organizations contain skeleton, muscles, nerves, blood vessels and so on. This article reviewed the comparisons of DO with conventional guided bone regeneration (GBR) and conventional orthognathic surgery (OGS), as well as the introduction of some of the recent case reports, clinical studies and post-surgery stability in relation to the dentoalveolus, maxilla and mandible regions. The success of DO is mainly related to the surgical treatment plan and the techniques. Same as the OGS, pre-surgical DO also entails exact paper and model surgery for prediction of distraction method. For the DO surgery, surgical trauma should be avoided to maintain the vitality of the skeletal structure and surrounding soft tissue. After the distraction, taking the X–ray of the distraction site is necessary to ensure the calcification of the regenerated bone, which determines the duration of consolidation period. The distractor can only be removed after a well calcified regenerated bone has been found on the radiograph. In conclusion, DO presents an alternative to conventional OGS that appears to have some advantages for large advancements in the maxilla and the mandible.
