Bone Grafts

Bone grafting represents a therapeutic modality in orthopedic surgery, maxillofacial surgery and dentistry, among other disciplines, that seeks the reconstruction and repair of bone defects. This procedure involves the transfer of bone tissue from one anatomical location to another with the purpose of restoring the structural or functional integrity of the compromised bone.

There are several categories of bone grafts, each with its own particular characteristics. Autologous grafts, for example, use the patient's own bone tissue, extracted from anatomical areas such as the iliac crest or the mandible. In contrast, allogenic grafts use tissue donated from deceased human sources, previously processed and sterilized for implantation.

In addition, there are synthetic or alternative material grafts, which are composed of substances designed to replicate the properties of bone, such as ceramics, biocompatible polymers or hydroxyapatite composites. Finally, xenogeneic grafts are based on animal bone tissue, which undergoes a denaturing process to minimize its immunological reactivity prior to use in human patients.

The type of bone graft selected depends on several factors, including the location and extent of the bone defect, the availability of donor tissue, the patient's preferences and the surgeon's clinical evaluation. These procedures, although fundamental to medical practice, require careful planning and execution to ensure optimal results and minimize potential risks, such as graft rejection or surgery-related complications.
