Implant Loading

The aim is to describe bilateral vertical ridge augmentation with intraoral block grafts and guided bone regeneration in the posterior mandible in preparation for implant placement. A 61-year-old woman, edentulous in the posterior mandible, presented for implant rehabilitation. The radiographic study showed 3 to 6 mm of bone height from the ridge to the mandibular canal. Autogenous bone block grafts from the chin and the mandibular ramus, harvested with ultrasonics, were used to augment the alveolar ridge. To reduce resorption, the grafts were covered with particulate alloplastic material and a collagen membrane. Delayed implants were placed 6 months after vertical augmentation, and 3 months later implants were loaded with a fixed prosthesis. A temporary sensory complication occurred, but 12 months after implant loading, there were no failures. In this case report block bone grafting was a feasible option to vertically augment the alveolar ridge in the posterior mandible.

Combined Use

Background. Bone augmentation ensures a favorable 3-dimensional position of implants. Onlay grafting is one of the techniques in ridge augmentation, which can be performed with the use of xenogenous blocks. Methods. Three cases of the vertical and horizontal ridge are discussed, which were augmented using xenogenous blocks. The blocks were shaped in a favorable size and puzzled along the grafting area. All the gaps were filled with granular xenografts. The flaps were coronally advanced to obtain primary closure. Results. An average of 4.2-mm gain in width and 4.2-mm gain in height of the ridge was observed at the implantation stage. Conclusion. The outcomes of these cases could pave the way for suggesting xenograft blocks for augmenting wide areas of the alveolar ridge on average of 4 mm in width and height in selected cases as an alternative to standard autogenous blocks. Long-lasting xenograft ensures implant and lip support in the esthetic zone.

Background. The placement of an implant in a previously infected site is an important etiologic factor contributing to implant failure. The aim of this case report is to present the management of retrograde peri-implantitis (RPI) in a first maxillary molar site, 2 years after the implant placement. The RPI was treated using an air-abrasive device, Er,Cr:YSGG laser, and guided bone regeneration (GBR). Case Description. A 65-year-old Caucasian male presented with a draining fistula associated with an implant at tooth #3. Tooth #3 revealed periapical radiolucency two years before the implant placement. Tooth #3 was extracted, and a ridge preservation procedure was performed followed by implant rehabilitation. A periapical radiograph (PA) showed lack of bone density around the implant apex. The site was decontaminated with an air-abrasive device and Er,Cr:YSGG laser, and GBR was performed. The patient was seen every two weeks until suture removal, followed by monthly visits for 12 months. The periapical X-rays, from 6 to 13 months postoperatively, showed increased bone density around the implant apex, with no signs of residual clinical or radiographic pathology and probing depths ≤4 mm. Conclusions. The etiology of RPI in this case was the placement of an implant in a previously infected site. The use of an air-abrasive device, Er,Cr:YSGG, and GBR was utilized to treat this case of RPI. The site was monitored for 13 months, and increased radiographic bone density was noted.
