Immediate transmucosal implant placement in fresh maxillary and mandibular molar extraction sockets: description of technique and preliminary results.
OBJECTIVE
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.


CONCLUSIONS
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.
