Bone morphogenic protein oral graft

Large mandibular defects in children are an uncommon but challenging problem for surgeons to solve. The time-honored options of autologous bone grafts are seldom a viable option, as suitable donor sites are unavailable. Osteoinductive morphogens may yet provide a solution in these cases. A large mandibular tumor in a child 10 years of age necessitated the resection of the entire dentate portion of the mandible. The defect was reconstructed at a second stage with a composite graft of human transforming growth factor-β3 (hTGF-β3), human demineralized bone matrix, and 12 g of autologous bone harvested from the posterior iliac crest...

The reconstruction of complex midface defects is a challenging clinical scenario considering the high anatomical, functional, and aesthetic requirements. In this study, we proposed a surgical treatment to achieve improved oral rehabilitation and anatomical and functional reconstruction of a complex defect of the maxilla with a vascularized, engineered composite graft. The patient was a 39-year-old female, postoperative after left hemimaxillectomy for ameloblastic carcinoma in 2010 and tumor-free at the 5-year oncological follow-up...

Recent studies have indicated the use of recombinant human bone morphogenetic protein-2 (rhBMP-2) to be a viable adjunctive to alveolar cleft reconstruction owing to its osteoinductive capacity. This study aimed to evaluate the efficacy of rhBMP-2 in the treatment of alveolar cleft with autologous bone grafts by precise volumetric analysis. Twenty-six patients (aged 8-14) with unilateral alveolar clefts were enrolled in this comparative study. Patients were divided into two groups: the iliac crest bone graft (ICBG) was placed at the side of the cleft in the control group (ICBG group), and rhBMP-2 was mixed with the ICBG in the rhBMP-2 group (BMP group)...

Soft and hard tissue engineering has expanded the frontiers of oral/maxillofacial augmentation. Soft tissue grafting enhancements include improving flap prevascularization and using stem cells and other cells to create not only the graft, but also the vascularization and soft tissue scaffolding for the graft. Hard tissue grafts have been enhanced by osteoinductive factors, such as bone morphogenic proteins, that have allowed the elimination of harvesting autogenous bone and thus decrease the need for other surgical sites...

STUDY DESIGN: Retrospective Analysis OBJECTIVE.: The aim of this study was to determine whether an association between increased acute pain, postoperative time, and direct hospital costs exists between the use of iliac crest bone grafting (ICBG) and bone morphogenic protein (BMP)-2 following a primary, single-level minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). SUMMARY OF BACKGROUND DATA: ICBG has been associated with enhanced fusion rates...

PURPOSE: Reconstruction of hard tissue continuity defects caused by ablative tumor surgery has been traditionally reconstructed with autogenous bone grafts or microvascular free flaps. Although results have been predictable from these 2 methods of reconstruction, the morbidity associated with bone harvest is quite serious for the patient. Predictable results have been obtained with using a combination of 100% cadaver bone, bone marrow aspirate concentrate (BMAC), and recombinant human bone morphogenic protein in immediate reconstruction for benign tumor extirpations through the extraoral approach...

Reconstruction of the atrophic maxilla is a difficult task. The gold standard for such reconstruction is autogenous bone. Presently, many excellent products are available to the dental surgeon to facilitate alveolar reconstruction in the absence of autogenous bone. This study describes the use of bone morphogenic protein in combination with allogenic bone substitute (Puros) to reconstruct the maxilla in preparation for dental implant placement.

The present study examined the effect of aging on epithelium and on its ability to respond to an inductive stimulus provided by murine dental papillae. In fetal CD-1 mice, 15- to 17-day molar mesenchyme was combined with 15- to 19-day epithelium from the secondary palates. Enamel organs were separated from the dental papillae, and palatal epithelium was peeled away from its underlying mesenchyme after treatment with 1% trypsin. Recombinants of epithelium and papillae were initially cultured on a solidified complex medium for 24 hr followed by an additional 10-14 days of intraocular explanation...
