Clinical Case Report
Peri-implantitis Treated by an Antimicrobial and Regenerative Approach
A 73-year-old woman was referred to the Division of Periodontology (University of Geneva School of Dental Medicine) after repeated unsuccessful treatment of a peri-implant infection. She was systemically healthy and did not smoke. The patient’s history revealed that, three years earlier, an immediate implant (Straumann Tapered Effect RN 4.8/4.1; Institut Straumann AG, Basel, Switzerland) had been inserted to replace the upper right central incisor. A metal-ceramic crown had been delivered using an adhesive resin cement. One year later, the patient had consulted another dentist due to discomfort in the soft tissues in the implant region. There was a suppurating peri-implant pocket, 10 mm deep. Peri-implant bone loss and excess luting cement were seen on the radiograph. The situation was treated with non-surgical debridement, amoxicillin, and repeated submucosal irrigation with a chlorhexidine digluconate solution. The patient was referred after the suppuration had persisted for several months.

* General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.
** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
