Early re-entry procedure. Part II. A five year histologic evaluation

Area of Science:

• Periodontology and Regenerative Medicine
• Oral and Maxillofacial Surgery
• Biomaterials Science

Background:

• Assessing the long-term histologic integrity of bone grafts is crucial for understanding regenerative outcomes.
• Clinical success of a bone graft 5 years post-implantation prompted a detailed histologic examination.

Observation:

• A tooth requiring extraction due to labial root fracture was removed 5 years after bone grafting.
• Histologic analysis of the extracted tooth and surrounding bone graft was performed.
• The evaluation focused on the periodontal membrane apparatus and bone/cemental remodeling status.

Findings:

• Histology revealed a functional periodontal membrane apparatus with active bone and cemental remodeling.
• Presence of necrotic bone spicules indicated residual graft material within a viable periodontium.
• The graft material was integrated and supported periodontal regeneration.

Implications:

• Histologic findings support the clinical success of the bone graft.
• Early re-entry for evaluation and contouring of autogenous grafts is justified.
• No adverse effects on local periodontal regeneration were observed.
