Using Chin Bone Rings for Sinus Lifting and Dental Implants in One Surgery
Sponsor: Damascus University
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.

Bone Ring Technique (BRT)
The Bone Ring Technique (BRT) is a one-stage surgical procedure that combines external maxillary sinus floor elevation with simultaneous dental implant placement. An autogenous bone ring is harvested from the mandibular symphysis using trephine burs. The sinus membrane is elevated via a lateral window approach created with a straight handpiece and diamond round bur. The bone ring is then placed into the sinus cavity, and a dental implant is inserted through the ring into the residual alveolar bone. The surgical site is augmented with xenograft particles and covered with a collagen membrane.
