What is the recommended treatment for a three-wall intrabony defect?

The recommended treatment for a three-wall intrabony defect involves the use of autogenous bone from the surgical site. This approach is favored for several reasons.

First, autogenous bone grafts have superior biological properties because they contain viable osteogenic cells, growth factors, and an extracellular matrix that promotes bone healing and regeneration. The use of bone harvested from the patient's own body reduces the risk of immunologic rejection and enhances integration at the defect site.

Additionally, when using autogenous bone, the clinician can achieve the ideal contour and volume needed to support the regeneration of the alveolar bone, which is crucial for maintaining tooth stability and ensuring periodontal health.

While regenerative therapy using allografts is a viable option in many cases, autogenous grafts are often considered the gold standard due to their biological advantages. Osseous reshaping may address some defects but does not promote new bone formation as effectively. Extraction of affected teeth might be warranted in cases of severe bone loss or periodontal disease, but it is not a directed treatment for the intrabony defect itself. Therefore, utilizing autogenous bone from the surgical site is a focused and effective strategy for treating three-wall intrabony defects.
