Which of the following is a type of autograft site?

An autograft refers to tissue that is transplanted from one site to another on the same individual. In this context, the cranium qualifies as a type of autograft site because it can provide bone grafts for other parts of the body, particularly in dental and periodontal surgeries. Bone harvested from the cranium can be used effectively to augment areas that require bone regeneration or repair, such as the mandible or maxilla.

The mandible, while it can be a source for grafting, is not specifically regarded as a common autograft site in the same way the cranium is when considering standard practices in periodontal treatment. Similarly, while the liver and pancreas can undergo transplantation, they do not commonly serve as sites for harvesting grafts in periodontal contexts, nor are they typically used for autografts in dental surgeries. The cranium is particularly noted for its accessibility and suitability in providing graft material that closely matches the recipient site.
