Using Chin Bone Rings for Sinus Lifting and Dental Implants in One Surgery
Conditions: Maxillary Deficiency, Bone Resorption
Sex: All
Ages: 18 Years – 70 Years
Healthy volunteers: No
Phase: NA
Enrollment: 10
Sponsor: Damascus University
Location: Oral and Maxillofacial Surgery Hospital, Faculty of Dentistry, Damascus University, Mezzeh Highway, Damascus, Syria Damascus Governorate
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.
