A submerged DO distractor was anchoraged on the zygoma and maxilla across the defect,the zygoma was distracted with a rate of 1.0 mm/d for ten days,the process of bone formation was examined by X-ray.Results:All dogs were in health condition within the experimental period.New bone formation was observed 2~4 weeks after operation. Complete repair of the defects was observed 8 weeks after the completion of distraction.Conclusion:The partial maxillary defect may be repaired by DO in zygoma.
