This is a chronic generalized or monostotic bone disorder of an unknown cause that occurs predominantly in the 6th and 7th decade of life in males. In contrast to Albert Schoenberg’s disease, the cortical bone is transformed into a fine-meshed cancellous bone, the medullary spaces of which are filled with fibrous tissue.¹⁵

In addition to the rheumatic complaints, an increase in the circumference of the skull is characteristic, which in extreme cases presents as Leontiasis ossea (lion face) with a high skull cap, pronounced prominent zygomatic bones, increased eye relief, and distension of the maxilla. Radiologically, brightening and shading occur, resembling a cotton flake structure, and the affected bone is generally thickened. Nowadays, the bisphosphonates described above are usually administered intravenously to stabilize the bone. Due to the altered bone metabolism, a strict indication for implant or augmentation therapy is recommended. The initial case reports show positive treatment outcomes, although there are as yet no long-term studies.^75,76,90 If necessary, modeling osteotomies can be performed to improve the prosthetic anchorage on the deformed alveolar process.
