Peri-implantitis

Peri-implant infections are pathological conditions surrounding dental implants. Mucositis refers to inflammation and ulceration in the soft tissues around an implant and is a reversible host response to periodontal pathogens. Peri-implantitis, the destructive inflammatory process affecting both soft and hard tissue surrounding a dental implant, is more severe and leads to bone loss1.

The typical signs and symptoms of the diseases, as discussed in various consensus conferences, can be described as follows2-8:

Mucositis

  • Bleeding on probing
  • Redness and swelling of soft tissue
  • No loss of supporting bone

Peri-implantitis

  • Crater-like bone defect
  • Bleeding and/or suppuration on probing
  • No implant mobility
  • >4 mm peri-implant probing depth

A reliable diagnosis of peri-implantitis requires the simultaneous presence of all above listed signs and symptoms. A single feature alone is not sufficient for the diagnosis.

“The surgical treatment of a contained osseous defect caused by peri-implantitis may include GBR, e.g. with a combination of Geistlich Bio-Oss® and Geistlich Bio-Gide®.”
Prof . Giovanni E. Salvi, Bern, Switzerland

 

Treatment of peri-implantitis

Peri-implantitis should be treated systematically. Bacterial plaque removal with surgical and/or non-surgical therapy is essential to prevent further progression and prepare the defect for regenerative procedures9.

Guided bone regeneration with Geistlich Bio-Oss® and Geistlich Bio-Gide® regenerates the osseous defect after implant surface decontamination10.
