Abstract
The aim of this study was to evaluate the behavior of the alveolar ridge split technique in a series of surgical cases in anterior mandible for two-implant retained overdenture. Twelve patients were included in this study. The surgeries took place under local anesthesia and consisted of a mid-crestal incision and subsequent bone management with a piezoelectric system. Once the approximately 3 mm expansion had been achieved, the implants were installed and present defects were filled with autogenous bone harvested from the bone crest with a bone scraper. There was a fracture of the bone plate in 3 cases, the fractured plates stabilized with osteosynthesis screws. In each case the implants were simultaneously placed. A total of 24 implants were placed. In the second surgery no implants were lost. It can be concluded that the bone splitting/expansion seem to be a reliable, predictable, relatively non-invasive technique and presenting limited intraoperative complications to correct narrow edentulous ridges.
