Aim. The study was designed to evaluate the clinical treatment outcome of placing transmucosal implants into extraction. The purpose of the present clinical study was to test whether peri-implant bone defects can successfully be filled by applying both the bone and the bioresorbable materials for the guided tissue regeneration.
Methods. Twelve patients who required extraction of a single molar were treated with immediate placement of an ITI® implant (Dental Implant System). Guided bone regeneration (GBR) technique was always applied simultaneously using deproteinized bovine bone mineral. Implants and bone were covered with a resorbable collagen membrane. Clinical measurements were taken at 6 sites around each implant. Radiological and clinical parameters were measured at the time of implant placement and at follow-up after 1, 3, 6, 12 and 24 months. Prosthetic rehabilitation was performed 3 months after surgery using a porcelain fused to metal crown.
Results. Soft tissue healing, at all sites, was free of complications, independently on the width of bone defect. Radiographs showed strength contact between peri-implant bone and the fixture without any defect between bone and implant. Clinical examination showed absolute implant stability complying with Albrekts-son’s requirements.
Conclusion. The use of GBR with resorbable membrane to cover Bio-oss, in association with immediate implant insertion at posterior sites when there is a wide bone defect, also allows early defect filling and good stability, already in the first month, with the possibility of prosthetic loading after only 3 months.
