Abstract

Introduction: Clinicians tend to encounter unfavorable situations in the treatment of teeth with severe attachment loss. Periodontal regeneration has been a successful therapeutic approach in treatments that require a long-term prognosis improvement. This case shows the benefits of combined regenerative periodontal therapy in a patient with a molar severely compromised by furcation, intrabony defects and attachment loss to the apex. Case Report: The clinical case included an endo-periodontal, class III furcation and intrabony defects in a generalized periodontitis, Stage III Grade C patient. After non-surgical periodontal treatment and reevaluation, a full-thickness flap and surgical debridement were performed.
Dental root surface was treated with EDTA and enamel matrix derivatives and the defects were filled with allograft and platelet-rich fibrin, additionally a collagen membrane was applied over the graft. After a 12-month follow-up there was a resolution of the intrabony defects and periodontal regeneration. Clinical and radiographic evaluation also showed the partial resolution of the class III furcation defect. Conclusion: Combined periodontal regeneration can be a therapeutic approach to improve the prognosis and prevent the extraction of molars severely compromised by furcation, intrabony defects and attachment loss to the apex.
