Background:
Mandibular tumors in children are mostly benign, although they can be locally aggressive and rapidly progressing. Methods of reconstructing mandibular defects after the ablation of these lesions are still challenging. In the pediatric population, there is enormous periosteal osteogenic potential due to high cellular activity and viability of mesenchymal cells for new bone formation, which, together with grafts, can aid in spontaneous bone neo-formation (SBNF).
Case Report:
We present an uncommon case of well-shaped bone neo-formation of the ramus-condyle unit in a 3-year-old patient who underwent mandibular partial resection after being affected by a central giant cell granuloma. In addition, a literature review of all the main cases of SBNF after partial or total resection of this bone is presented, with the representative features outlined.
Conclusion:
Future studies focusing on the exact mechanisms of the periosteum in bone neo-formation should be conducted.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
