Bone grafts are becoming increasingly common in oral and maxillofacial surgery to improve bone healing procedures. Bovine bone as a xenograft is a representative osteoconductor and space filler; however, sometimes complications, such as infection and wound dehiscence are encountered with its use. We report the result of an eight-year follow-up of a xenograft case and processing methods of inorganic bovine bone along with a review of the literature. Xenograft (LUBBOC(R)) was used in a cyst enucleation site of the maxilla, as a bone substitute and space filler. Inflammation and infection were defined several times as lack of osseous contact between the graft and host bone, caused by remodeling failure over an eight-year period. Pathologic findings of the xenograft revealed dead bony trabeculae with inflamed fibrous tissue and actinomycosis.
