Enhancing the regenerative potential of guided tissue regeneration to treat an intrabony defect and adjacent ridge deformity by orthodontic extrusive force.

BACKGROUND: The biologic potential of the periodontal ligament (PDL) can be harnessed to solve complex clinical problems involving several dental disciplines. The purpose of this case report is to demonstrate that orthodontic extrusive force can enhance the regenerative potential of guided tissue regeneration (GTR) to eliminate an intrabony defect and augment a ridge deformity. METHODS: Regenerative therapy by open debridement with particulate anorganic cancellous bovine-derived bone xenograft (BDX), bioabsorbable membrane, and minocycline root conditioning was carried out. Eight weeks after the initial surgery, orthodontic extrusion and uprighting simultaneously were initiated. RESULTS: Radiographs and reentry documentation demonstrated that orthodontic extrusive force could enhance the regenerative potential of GTR. Consequently, the intrabony defect and alveolar ridge were successfully treated. CONCLUSION: This case report demonstrates that orthodontic-regenerative combined therapy can resolve complex clinical problems involving several dental disciplines.

Alveolar bone upper growth in furcation area using a combined orthodontic-regenerative therapy: a case report.

BACKGROUND: This case report demonstrates orthodontic and regenerative combined therapy in a 49-year-old male whose right maxillary premolar furcation had a bony defect with poor biologic width resulting from extensive subgingival caries. In these advanced interdisciplinary cases, crown lengthening with periodontal surgery alone does not solve the complex clinical problems. We believe that a combined orthodontic and periodontal regenerative combination therapy offers the best option for achieving a predictable outcome. METHODS: First, regenerative therapy by open debridement with a bioabsorbable synthetic bone graft, bioabsorbable membrane, and minocycline root conditioning was carried out. Eight weeks after initial surgery, orthodontic extrusion was initiated. RESULTS: Radiographs and reentry documentation suggest that the furcation defect associated with poor biologic width was successfully treated. CONCLUSION: This case report demonstrates that orthodontic-regenerative combined therapy can resolve complex clinical problems and enhance predictability.
