Aim: To evaluate the behavior of the alveolar ridge split technique in a series of surgical cases. Materials and Methods:  One hundred and fifty implants were included in this study for a total of 60 patients. The surgeries consisted of a mid-crestal incision and subsequent bone management with a piezoelectric system. The implants were placed after the alveolar bone was expanded by about 3mm and present bony defects were filled by a mixture of 50% autogenous bone and a xenograft (Bio-Oss®). Bone fracture of the buccal alveolar plate occurred in 8 cases, and those were stabilized with osteosynthesis screws. Implants were simultaneously placed in 140 cases, out of them 4 failures occurred due to membrane exposition. Results: The osseointegration success was estimated to be 97.5%. Conclusion: This study concluded that the bone splitting/expansion seem to be a reliable, predictable, relatively noninvasive technique with limited intraoperative complications. Clinical significance: The study revealed that the alveolar ridge split can be used as an effective technique for atrophic edentulous maxillary and mandibular bone

The bone split technique is used to increase the width of a narrow ridge for implant placement with high success rates. This technique was performed on a 53-year-old patient with bilateral mandibular posterior edentulous and fully edentulous maxilla. Implants placement was performed afterward with two-step modus operandi on the mandible and immediate placement on maxilla. A successful prosthetic rehabilitation was done following the healing phase. This approach led to full restoration of function and esthetic with a predictable outcome.

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.

Parathyroid hormone secreted by the parathyroid glands has a key role in the regulation of calcium and phosphorus metabolism and plays an essential role in tooth and bone mineralization. Disorders of the parathyroid glands most frequently result in abnormalities of serum calcium and can induce various oral and extra-oral manifestations. Therefore, a sound understanding of these conditions is essential for the dental practitioner, with emphasis on alerting signs, clinical and radiological findings and mandatory communication with patient’s physician.
