Introduction: Oral rehabilitation with implant-supported prostheses requires precise planning by means of clinical and imaging. For implants placement according to the needs of prosthetic restoration, a quantity and quality of remaining bone are needed. In unit cases, mainly in the anterior maxilla, the esthetic is more significant and special care is needed in relation to the vertical placement of the implant, color, size, shape and spatial position of three-dimensional prosthetic crown. In cases of planning failure on implants placement or errors in technique, implants may be poorly positioned, compromising the rehabilitation. In this case the solution involves the burial of the implant or removal and replacement it with considerable prolongation of treatment. The segmental osteotomy, widely used in orthognathic surgery, may represent an important alternative treatment for the correction of non-restorable implants in the anterior maxilla. Associated with this procedure, the technique of distraction osteogenesis can be used to assist the repositioning of implants for a position in favor of rehabilitation.
Case report: Male, 32 years-old, presented with malpositioned implants in anterior maxilla, with bone loss and aesthetic complains. The treatment proposed consisted in segmental osteotomy and distraction osteogenesis by orthodontic device for repositioning the two implants in the anterior maxilla and posterior restoration.
Conclusions: Segmental osteotomy and distraction osteogenesis represent an easy technique with high predictability. It presents an alternative treatment for malpositioned implants, preventing bone loss and implant removal.
