In addition to the above, iatrogenic factors such as faulty restorations, cement left following restoration delivery, and/or loose components can also play a significant role in the development of peri-implantitis.
Although restorations of endosseous implants have demonstrated a very high survival rate(1), one study suggested that over a five-year period, 0 to 14.4% of dental implants demonstrated peri-implant inflammatory reactions associated with crestal bone loss.(2)
Many methods of treating peri-implantitis have been documented in the literature and most focus on removal of the contaminating agent from the implant surface. These treatments include:
1. Administration of systemic antibiotics alone
2. Mechanical debridement with or without systemic antibiotic treatment(3)
3. Mechanical debridement with or without localized drug delivery and chlorhexidine oral rinses(3a)
4. Mechanical debridement combined with LASER decontamination(4)
5. Surgical debridement, and more recently…
6. Surgical debridement with guided bone regeneration (GBR) for reparation of bony and soft-tissue defects(5).
