The aim of this study was to investigate the long-term clinical conditions of periodontally compromised teeth treated by means of orthodontics after periodontal regeneration (GTR). Forty-eight patients affected by severe periodontitis who presented at least one nonmolar, malpositioned tooth with a pocket depth (PD) ≥ 7 mm, were consecutively enrolled in a private specialist practice. The treatment consisted of the following steps: infection control, provisional splinting, GTR, orthodontic treatment, final splinting, and supportive periodontal therapy (SPT). Thirty-six patients completed the 10-year study, as 12 were lost to follow-up. The total number of sites with PD ≥ 7 mm decreased from 25.4 16.7 to 1.8 2.1. PD of the teeth involved in the orthoperio treatment significantly decreased from 6.3 1.5 mm to 3.1 0.6 mm. One test tooth had to be extracted before the final examination due to root fracture, while two teeth lost vitality and received a root canal treatment. Eight episodes of recurrence, which required additional treatment, occurred during the 10 years of follow-up. The results of this study suggest that if a periodontal infection is under control, the orthodontic treatment does not reduce the long-term benefits of periodontal regeneration, even where the disease has caused massive tissue destruction.
