ZURICH, Switzerland: At a press event in Zurich on 15 February, Dr Roland Glauser, a Zurich-based expert in comprehensive implantology, highlighted peri-implantitis as a primary challenge in implant dentistry, a view supported by leading dental associations. Research shows that nearly half of patients experience peri-implant mucositis, often leading to peri-implantitis, which affects 22% of patients and is a leading cause of implant failure. The two-piece Patent Dental Implant System aims to combat this by preventing chronic tissue inflammation, and it was reported at the briefing that a new study on this zirconia system found no peri-implantitis after up to 12 years, even in compromised patients.
