BACKGROUND: Calvarial bone grafts as a pre-implant augmentation procedure are mostly used to reconstruct the edentulous maxilla, although calvarial grafts could also be used in the partially dentate patients needing extensive bone grafting.

METHODS: In 7 consecutive partially dentate patients needing bone grafting because of a large bony defect as a result of trauma (n = 1), oligodontia (n = 1), failed previous bone augmentation (n = 1), or atrophy (n = 4), the alveolar process was reconstructed with calvarial bone as a pre-implant procedure.

RESULTS: A total of 30 implants was placed either immediate at the time of bone grafting (13 implants) or after a healing time of 4 months when immediate placement was not possible (17 implants). One wound dehiscence occurred that needed secondary intervention. During follow-up (40 ± 14 months), one implant was lost due to peri-implantitis with an infected osteosynthesis screw. Marginal peri-implant bone loss was 0.65 ± 0.47 mm during this period.

CONCLUSION: Calvarial bone is a sound extra-oral donor site when aiming for reconstruction of a large bony defect of the alveolar process of partially dentate patients.
