Abstract:
A case of orthodontic replacement of impacted cuspid in fibrodysplastic maxillary bone in a 12-year-old girl is reported. Fibrodysplastic bone is classically described as a fibrous bone without osteoblastic rimming. It is well known that orthodontic forces lead to tooth movement through proliferation and increased activity of bone cells (osteoblasts and osteoclasts). The reported case clinically support the latest histological studies suggesting that in fibrodisplastic bone osteoblasts are present but altered in shape and therefore difficult to recognize in sections.
