What kind of materials can be used for bone grafting?

The selection of autografts, allografts, xenografts, and alloplasts encompasses a comprehensive range of materials suitable for bone grafting procedures.

Autografts are harvested from the patient’s own body, ensuring biocompatibility and minimizing the risk of immune reactions; they also promote bone healing through their inherent properties. Allografts are sourced from donors of the same species, usually providing a readily available option while still retaining osteoconductive properties, albeit with a potential risk of immune response.

Xenografts come from different species (commonly bovine or porcine) and provide a scaffold for new bone formation without the inherent biological materials of either the patient or the donor, while alloplasts consist of synthetic materials that are designed to mimic natural bone; these can be made from biocompatible substances that encourage new bone growth without the risk of disease transmission present in biological grafts.

The breadth of these materials allows for flexibility in selection based on availability, patient needs, and specific clinical scenarios, making option A the most accurate answer. In contrast, the other options do not capture the full range of viable grafting materials used in periodontal and general bone grafting surgeries.
