Abstract: Objectives: Bone distraction and grafting in block are the most suitable techniques in cases of large bone destruction.Then both techniques will be compared and an analysis based on the literature will be.Material and Methods: Search for articles, in the last 10 years, published in Medline (PUBMED) and EMBA-SE; key words: distraction osteogenesis, graft-block.Results: Distraction osteogenesis, offers lower infection rate, always soft tissues are won and there is a donor area morbidity.Its difficulty lies in directing the vector of distraction, although there is also a risk of necrosis of the absent-minded fragment, and its success depends on the behavior and care of the patient.Chin is a widely used donor area because it presents an acceptable bone, mainly cortical quantity, good surgical access.The main drawback is the morbidity from the donor area, which depends on the dimension of retrieved bone and surgical management.The most important aspect is to obtain a primary closure of the receiving area.Conclusions: To reset the bone volume in an atrophic maxilla, should be individualized each case, studying the form and severity of the defect.Horizontal defects in the technique of choice are bone grafts.While in vertical defects, alveolar distraction is a predictable method, particularly in the former sector.There are cases in which there is loss of vertical and horizontal, where you can combine both techniques.
