Brief Summary
This study evaluates the Bone Ring Technique, a single stage procedure that combines external sinus floor elevation and dental implant placement using an autogenous bone ring harvested from the chin. Ten patients with residual alveolar bone height ≤4 mm in the posterior maxilla will be enrolled. Implant stability (ISQ), vertical bone gain, peri implant bone density, and implant survival will be assessed over 6 months. The aim is to reduce treatment time and surgical interventions compared to traditional two stage approaches.
Eligibility Criteria
Inclusion Criteria: * Need for dental implant in posterior maxilla (premolar/molar). * Residual alveolar bone height ≤4 mm on preoperative CBCT. * Age ≥18 years. * Controlled systemic health. * Able to comply with procedures and follow up. * Good oral hygiene. * Signed written informed consent. Exclusion Criteria: * Uncontrolled systemic disease. * Head/neck radiotherapy. * Bisphosphonate therapy \>3 years. * Autoimmune disease affecting healing. * Pregnancy/lactation. * Active maxillary sinus pathology (sinusitis, cysts, polyps, tumours). * Heavy smoking (\>10 cigarettes/day). * Severe bruxism.
