Periodontal maintenance is an extension of active periodontal therapy. Periodontal maintenance is initiated after completion of active periodontal treatment and continues at varying intervals for the life of the dentition or its implant replacements. The goal of periodontal maintenance is to minimize the recurrence and progression of periodontal disease in patients with a history of previous periodontal treatment. Ultimately, regular periodontal maintenance reduces the incidence of tooth loss by monitoring the dentition and any prosthetic replacements of the natural teeth.
For most patients with a history of periodontitis, visits at three-month intervals have been shown to be effective in maintaining the established periodontal health. Based on clinical and radiographic evaluation and assessment of the periodontal status, periodontal maintenance frequency may be modified or the patient may be returned to active treatment.
