Abstract: Periodontitis is one of the most common causes of tooth loss，which adversely affects oral health and increases risk of suffering from some kind of systemic disease. The treatment goals of periodontal therapy involve periodontal inflammation elimination and disease progression termination，thus restoring oral function and aesthetics. In order to achieve these aims，clinicians should firstly proceed detailed periodontal examination and formulate proper treatment plan. To preserve natural teeth with advanced periodontal destruction，and maintain their function is a challenge to dentists. This article presented the comprehensive treatment process of a patient diagnosed with advanced periodontitis. By thorough periodontal initial therapy and proper periodontal surgery，inflammation was successfully controlled. Furthermore，removable partial denture was applied to replace the lost teeth and restore oral function. In the course of active periodontal treatment and afterwards，periodontal maintenance therapy was regularly performed. In the subsequent 6-year follow-up，a good therapeutic effect was observed. This article focused on treatment decision-making for patients with advanced periodontitis，and discussed the clinical efficacy of initial and surgical therapy on advanced periodontitis. Moreover，it also emphasized the importance of patient′s daily plaque control in regular professional maintenance therapy，which provided clinical experience for management of advanced periodontitis.
