The purpose of this study is to determine whether concurrent cancellous bone grafting can effectively reduce problems and speed up healing in aggressive mandibular lesions treated with liquid nitrogen cryotherapy and enucleation. Ten of the twenty patients that were evaluated had concurrent bone transplantation, while the other ten did not. In contrast to events in the non-grafted group, where two patients suffered from pathologic fractures and one from a wound dehiscence, complications did not arise in the bone-grafted group. The grafted group had a higher residual bone height, and only osseointegrated implants were inserted in this group. According to the study's findings, simultaneous bone grafting reduces risks, maintains bone height, and makes it easier to insert dental implants in lesions larger than 4.0 cm.
