Proplast grafting: A new method for stabilization of maxillary advancements

Sliding Genioplasty Using Fresh-Frozen Bone Allografts

“…8 Various autologous, heterologous, and alloplastic interpositional grafts have been described as grafting interpositional materials in cases of mandibular advancement, maxillary Le Fort I osteotomy, and chin osteotomies. 9 The main types of graft materials are autogenous bone grafts, 4 freeze-dried bone, 10 alloplastic material (Proplast; Vitek Inc) blocks, 11 solid block of hydroxyapatite, and porous block of hydroxyapatite. 12 The autogenous bone grafts represent the "gold standard" because of their osteogenic potential, osteoconductivity, and osteoinduction, 13 but the use of autogenous grafts implies the availability of a donor site, thus increasing morbidity and operative time.…”
