Introduction:
The onset of one or several diastema in adults with no link of etiology to tooth loss or to a periodontal problem can be the first evocative sign of an acromegaly or a benign or malignant tumoral process.
Observation:
A 40-year-old patient consulted for an implant to solve an esthetic problem caused by a diastema. The complementary exams revealed an osteolytic lesion marked by condensing areas. The biopsy proved the diagnosis of fibrous dysplasia.
Discussion:
Etiologies of fibrous dysplasia are varied. They can be related to a congenital defect of osteo mesenchyma development or be the consequence of trauma, reaction to infection, or an endocrine or metabolic disorder.

Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Bone Formation by Intramembranous Ossification
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
