Abstract

Objective: The aim of this study was to compare 2 types of bone used for maxillary sinus floor augmentation, corticocancellous block or particulate bone grafts, on bone healing around dental implants when installed simultaneously with the implant. Study design: The mucous membranes of 12 sinuses in 6 dogs were elevated bilaterally. On one side of the maxillary sinus, autogenous corticocancellous block bone was grafted into the space between the membrane and sinus wall. On the opposite side, autogenous corticocancellous particulate bone was grafted. Simultaneously, 2 dental implants were inserted into the grafting material through the maxillary sinus floor. The animals were killed 6 months after surgical procedure. Results: The mean bone-implant contact was 56.7% on the block side and 32.1% on the particulate side (P < .05). The mean height of newly formed bone in the augmented area was 12.3 mm on the block side and 9.7 mm on the particulate side (P < .05). Conclusion: Our results show that maxillary sinus floor augmentation using corticocancellous block bone grafts, when installed simultaneously with the implant, is superior to corticocancellous particulate bone grafts for bone healing around dental implants.
