Vertical alveolar bone deficiency after traumatic tooth extractions or cysts and tumor removal is still being a big challenge for implant rehabilitation. For this purpose, inlay bone grafting and distraction osteogenesis are the main techniques has been used. On the other hand, the price of the distractors and close clinical follow requirements and deviations of the transport segments are the leading problems of this method. To overcome these disadvantages inlay bone grafting can be used as a alternative vertical augmentation method, especially in the anterior mandibular region, for implant rehabilitation. The aim of this report is to assess the efficacy of the sandwich osteotomy for vertical augmentation in the atrophic segment of anterior mandible through clinical studies.
