Abstract
Background
Alveolar bone is usually resorbed after the loss of a tooth. As the buccal bony plate of the alveolar bone is thin compared to the palatal or the lingual bony plate, the bone resorption rate is higher on the buccal side. If a patient is partially edentulous, vertical bone resorption is restricted by the adjacent teeth. In such a case, the residual alveolar ridge becomes thin and narrow. As a result, a veneer graft is required.
Case report
Two patients received a total of two implants with a modified technique. The modified technique is described in which the implant hole is made in both the mandibular ramus and the recipient site. Autogenous bone was taken from the mandibular ramus as a partial-thickness graft. The grafted bone was adapted to an installed dental implant and used as a veneer graft. There were no cases that showed the fixture exposure during the follow-up periods. Numbness was not reported after the operation in any of the cases. Additionally, osseointegration failures did not occur during the follow-up periods.
Conclusion
Our technique has been shown high success rates and is reproducible for a veneer bone graft with concomitant implant installation.
