Objective:
To study the possibility of segmental maxillary regeneration by arced distraction osteogenesis of zygoma.
Methods:
The distraction of zygoma with the internal arced devices was performed in 2 dogs to simulate the reconstruction of maxillary defect. The zygoma was distracted about 12 mm, and the process of new bone formation was studied by histology and scanning electron microscopy.
Results:
The transport disk was distracted about 12 mm around the arc. After 8 weeks of consolidation, the density of new bone was close to that of normal bone.
Conclusions:
The segmental maxillary regeneration by arced distraction osteogenesis of zygoma is possible.
