Horizontal and vertical maxillary osteotomy stability, in cleft lip and palate patients, using allogeneic bone graft

Abstract

The use of allogeneic bone graft in cleft lip and palate patients submitted to Le Fort I osteotomy contributed to increase postoperative stability when compared to surgeries without bone graft.

Impact of the Distance of Maxillary Advancement on Horizontal Relapse After Orthognathic Surgery

“…One of our additional finding was that bone grafting of the gap created by Le Fort I osteotomy had a protective effect on maxillary relapse, with an average of 1.723 mm less relapse compared to patients without bone grafting. This has been reported previously and should play a role in preoperative planning of the surgical intervention (Gomes et al, 2013;Eser et al, 2015). Our preferred choice for bone graft is autologous bone taken from either BSSO or maxillary osteotomy sites; however, cadaveric bone graft may also be used.…”

Relapse rate after surgical treatment of maxillary hypoplasia in non-growing cleft patients: a systematic review and meta-analysis

“…The relapse tendency in CLP patients is influenced by intrinsic factors, such as scarring, muscle pull, tension in the soft tissues, the stability of bony fragments, and the severity of the maxillary hypoplasia 7,37,47,53 . In addition, treatment factors such as the presence or absence of interpositional bone grafting in LFI, use of different distraction devices in DO, and the occlusion achieved, all have an impact on the relapse tendency 5,7,[13][14][15]18,21,54 .…”

Dental Implant Placement in Inadequate Posterior Maxilla

“…Although, allogeneic bone grafts do not have the drawbacks of autografts, the procedure is more delicate and less successful in clinical practice. They also display several other disadvantages: risk of disease transmission of the donour site, infection, difficulties in obtaining and processing, possible rapid resorption [38,39], and partial loss of mechanical strength after sterilization [40]. Xenogenic bone substitutes of porcine, bovine, or, more recently, equine origin are used because of their chemical and structural composition similarity when compared to human bone [32].…”
