Abstract

Abstract: Objective: This case report presented a three-year follow-up observation of a 49-year-old male patient with StageⅢ Grade C periodontitis who underwent periodontal regenerative surgery on mandibular premolars. Additionally, a literature review was conducted on factors influencing periodontal regeneration. Diagnosis and treatment: Through standardized periodontal maintenance therapy and regeneration on the proximal surface of mandibular premolars, the patient's heavily involved periodontitis teeth were salvaged in a timely manner. Results: The overall periodontal health status was significantly improved, with sustained and stable periodontal control. Conliusions: The loss of interproximal attachment in periodontally involved teeth is closely associated with tooth prognosis, and the regeneration of interproximal attachment levels in periodontitis can significantly improve the prognosis of affected teeth.

Key words: periodontitis, periodontal initial therapy, periodontal supportive therapy, guided tissue regeneration, intra-bony defects
