Failure of Maxillary Reconstruction With Freeze-Dried Bone Allograft

Bone reconstruction to reestablish bone width and height is required in case of bone atrophy. A 45-year-old white woman was referred to the oral clinical surgery of Aracatuba Dental School, University Estadual Paulista-UNESP, in 2013 with the main complain of bone exposure at the superior right site of the maxilla after 1-year reconstruction with bone block allograft. Bone block was removed besides the dental implant next to the bone allograft. Complication of bone allograft could jeopardize treatment planning.
