Int J Periodontics Restorative Dent 39 (2019), No. 2 25. Mar. 2019
Implant-supported prosthetics are a suitable option for improving partially and totally edentulous patients' oral life quality, especially those patients with a history of periodontitis who experience early tooth loss and therefore require implant therapy. However, long-term clinical studies on dental implants have indicated that patients with periodontitis show more biologic complications and lower survival and success rates compared to periodontally healthy patients. The two clinical reports presented show that patients with aggressive periodontal diseases treated with a supportive periodontal therapy can be successfully rehabilitated with implantsupported double-crown restorations for a follow-up period of over 20 years.
