title: Alveolar bone upper growth in furcation area using a combined orthodontic-regenerative therapy: a case report.
abstract: 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.
  
  
  CONCLUSIONS
  This case report demonstrates that orthodontic-regenerative combined therapy can resolve complex clinical problems and enhance predictability.
