Expansão alveolar em volume para colocação de implantes em região estética de maxila

Abstract

The objective of this monography is to review the literature on horizontal ridge augmentation in the anterior maxilla region with expansion crest techniques. Studies in english and portuguese languages were revised and searched at Medline/Pubmed and CAPES portal. The resorption of the ridge after tooth loss occurs in a faster pace and in a greater degree in width, which normally avoids reconstruction with osseointegrated implants. The treatment with alveolar expansion can be an effective, faster, less painful and a cheaper alternative. However, it is not applicable to every case, since there are certain rules to be followed for its use, such as presence of cancellous bone and alveolar ridge wider in the base than in the crest. Despite that, when well applied, this technique presents good gain in ridge width and the success rate of the implants inserted in this areas are similar to the ones placed in wide ridges with good height.
