The term that describes the condition where normal bone structure is replaced with fibrous tissue is fibrous dysplasia. In this disorder, bone is progressively replaced by fibrous tissue, resulting in deformities and potential pain. This condition can affect one bone (monostotic fibrous dysplasia) or multiple bones (polyostotic fibrous dysplasia) and can lead to structural weaknesses in the affected bones.

The other options refer to different conditions: Gardner's syndrome is a genetic disorder characterized by the development of various tumors and dental abnormalities, including osteomas and soft tissue tumors, rather than the replacement of bone with fibrous tissue. The calcifying epithelial odontogenic tumor, also known as a Pindborg tumor, is a benign odontogenic neoplasm characterized by the presence of calcifying epithelial cells, but it does not involve the replacement of bone. A dentigerous cyst is an odontogenic cyst associated with the crown of an unerupted tooth, which may cause localized bone expansion but does not lead to the replacement of normal bone structure with fibrous tissue.
