Objective:
Sticky bone, a composite of porcine-derived xenograft bone material and serum components obtained from autologous blood centrifugation, was implanted into the anterior mandibular alveolar bone during periodontally accelerated osteogenic orthodontics (PAOO) in a patient with skeletal Class III malocclusion. The augmentation and stability of the alveolar bone in the grafted area were evaluated over a 1-year follow-up period.
Methods:
A patient with skeletal Class III malocclusion underwent PAOO surgery as part of presurgical orthodontic treatment. During the procedure, sticky bone was used as a substitute for traditional granular bone, while autologous blood components were centrifuged to form barrier membranes. Cone-beam computed tomography (CBCT) scans were taken before treatment, and at 6 months and 1 year post-PAOO surgery. The height and thickness of the bone graft in the anterior mandibular region were measured using Blue Sky Plan software.
Results:
The measurements showed that, although minor absorption of the bone graft occurred 1 year after surgery, CBCT scans at the completion of orthodontic treatment revealed a 1 to 3 mm layer of exogenous bone still covering the middle and upper thirds of the root in the mandibular anterior region. This bone grafting technique effectively corrected bone dehiscence.
Conclusions:
In this case, sticky bone, a combination of heterologous bone material and autologous blood barrier membranes, successfully preserved the bone height and thickness 1 year after PAOO surgery. The use of sticky bone for bone augmentation proved to be an economical and reliable method with long-term stability. Future controlled studies with larger sample sizes are needed to further validate the clinical applicability of this approach in treating anterior mandibular alveolar defects.
