Surgical Treatment of Peri-Implantitis: A 17-Year Follow-Up Clinical Case Report

Abstract

The purpose of the present case report was to describe the surgical treatment of a peri-implantitis lesion associated with a regenerative approach. A 48-year-old patient came to authors' attention 36 months after the placement of a dental implant (ITI-Bonefit Straumann, Waldenburg, Switzerland) in position 46. A swelling of the peri-implant soft tissues was observed, associated with bleeding on probing and probing depth > 10 mm. A significant peri-implant bone loss was clearly visible on the periapical radiograph. A nonsurgical periodontal supportive therapy was firstly conducted to reduce the inflammation, followed by the surgical treatment of the defect. After mechanical and chemical decontamination with tetracycline solution, a regenerative approach consisting in the application of deproteinized bovine bone mineral (Bio-Oss, Geistlich Pharma AG, Wolhusen, Switzerland) and a collagen membrane (Bio-Gide, Geistlich Pharma AG, Wolhusen, Switzerland) was performed. An antibiotic therapy was associated with the treatment. The 17-year follow-up showed a physiological probing depth with no clinical signs of peri-implant inflammation and bleeding on probing. No further radiographic bone loss was observed. The treatment described in the present case report seemed to show improved clinical results up to a relevant follow-up period.

A bioabsorbable collagen membrane was placed in order to create a secluded space over the DBBM graft.

Figure 7
Postoperative intraoral radiography. The graft filled into the bone defect was observable in close contact with the implant surfaces. During the healing period the implant was left unloaded.

Clinical situation during the follow-up recall. Peri-implant soft tissues appeared healthy, with no sign of inflammation and suppuration.

17-year follow-up intraoral radiography. The peri-implant marginal bone levels appeared radiographically stable, without any sign of bone resorption mesially and distally to the implant.
