In this case report, the shell technique with both autogenous and allogenic bone struts (maxgraft® cortico) was used for vertical bone augmentation in an atrophied mandible.

Method:

A 61-year-old female patient had a pronounced bone atrophy in both quadrants of the mandible, which had to be rehabilitated by bone augmentation for a later prosthetic implant restoration. In order to avoid the burden of a second retromolar bone harvesting, one quadrant was built up using the shell technique with autogenous bone struts and the other quadrant using the shell technique with allogenic bone struts (maxgraft® cortico). After a 4-month healing period, implantation with additional GBR procedure (augmentative relining) with cerabone® and Jason® membrane was performed.

Results and conclusion:

After another 4 months healing time, the implants were exposed. Vertical bone augmentation using the shell technique with autogenous and allogenic bone struts led to equivalent results. maxgraft® cortico is therefore a valid alternative to autogenous bone blocks. By means of a special relining technique, the alveolar ridge could be further optimized and protected from possible later resorption processes after the prosthetic restoration.
