DFDBA Allograft to Accelerate the Healing in Lefort's Osteotomy Sites
Objectives: to evaluate the effects of demineralized freeze dried bone allograft (DFDBA) with putty consistency on the healing process of Lefort’s osteotomy sites in orthognathic surgery.
Methods: This split-mouth study was performed on patients requiring Lefort’s osteotomy for surgical advancement of the maxilla after orthodontic treatment. After the surgical procedures and before soft tissue suturing, the osteotomy site on one site of the maxilla was randomly selected for placement of DFDBA, while the other side was considered as the control site. Computed tomography (CT) scans of the patients were obtained preoperatively and 4-month postoperatively. The area of the osteotomy defects in three-dimensional frontal and lateral reformations were compared before and after the surgical procedure on both sides. The data was then statistically analyzed (α=0.05).
Results: 20 patients participated in this study. Preoperatively, the area of the defects on the control and DFDBA sites were not significantly different (P=0.810). After 4 months, the area of the defect was not significantly different between DFDBA and control sites (P=0.628).
Conclusions: Application of DFDBA with putty consistency is not effective on healing of Lefort’s osteotomy sites. Therefore, it is not recommended for routine use in orthognathic surgeries for the purpose of healing acceleration.
