Insights from this study for clinical practice<\/strong><\/p>\n\n\n\n Peri-implantitis is a major and growing problem in dentistry, necessitating inconvenient and uncomfortable treatment for the patient and using valuable dentists' resources. However, information on prevalence of peri-implantitis is limited, with many studies looking only at small patient groups. To counter this, a group of experts from Gothenburg, Sweden, report their findings from a large, real-world population.<\/p>\n\n\n\n The authors performed a retrospective analysis of 2,765 randomly selected patient files from a Swedish registry, and clinical and radiological examination of patients at a mean of 9 years after implant-supported restorative therapy. The final analysis included 588 patients and 2,277 implants. Peri-implantitis was defined as bleeding on probing\/suppuration and detectable bone loss >0.5 mm, with moderate\/severe peri-implantitis showing bone loss >2 mm.<\/p>\n\n\n\n The authors found that nearly half of patients undergoing implant-supported restorative therapy suffered from peri-implantitis 9 years after the procedure.<\/p>\n\n\n\n This classic, unique study conducted by renowned authors examined various design parameters of implant systems commonly used today for their influence on risk of peri-implantitis.<\/em><\/strong><\/p>\n<\/blockquote>\nDr. med. dent. Konrad Meyenberg<\/cite><\/blockquote>\n\n\n\n Of the 427 patients with baseline radiographs, 192 (45.0%) had peri-implantitis, including moderate\/severe peri-implantitis in 62 patients (14.5%). Patients with moderate\/severe peri-implantitis experienced a bone loss corresponding to 29.4% of the intraosseous portion of the implant.<\/p>\n\n\n\n The authors investigated risk factors for moderate\/severe peri-implantitis, and found significantly higher odds ratios associated with periodontitis, having \u22654 implants, general practitioner-delivered therapy, and implant type\/characteristics (referred to as implant brand in the original publication). Furthermore, multilevel analysis found significantly higher risk of peri-implantitis with mandible implants and with a prosthetic margin to crestal bone distance of \u22641.5 mm.<\/p>\n\n\n\n A history of periodontitis affects the success of implant treatment.<\/strong><\/em><\/em><\/p>\n<\/blockquote>\nDr. med. dent. Karin Wolleb Torrisi<\/cite><\/blockquote>\n\n\n\n In addition to patient-related factors, the design of the implant itself plays a critical role in peri-implantitis risk. A detailed review of implant types and characteristics from the different brands revealed that the lowest risk was associated with a gold standard design, characterized by a machined (smooth) supraosseous implant collar combined with an intraosseous sandblasted and acid-etched surface. These designs are commonly referred to as \"soft tissue level\" or \"hybrid designs.\"<\/p>\n\n\n\n Conversely, implants with rough or porous collar surfaces (e.g., anodized) were associated with a three-fold higher risk of peri-implantitis (implant brands NB and AT versus S: ORs 3.8, 3.6 versus 1, respectively). Notably, this elevated risk persisted regardless of other implant features, such as connection type or vertical positioning.<\/p>\n\n\n\n These findings emphasize that selecting an implant with a smooth, machined collar can significantly reduce peri-implantitis risk, independent of the surgical or prosthetic protocol.<\/p>\n\n\n\n The lowest risk of peri-implantitis is associated with the gold standard supraosseous machined implant collar in combination with intraosseous sandblasted and acid-etched surface.<\/strong><\/em><\/em><\/p>\n<\/blockquote>\nDr. med. dent. Konrad Meyenberg<\/cite><\/blockquote>\n\n\n\n Much of the information on implant outcomes comes from limited samples and focuses on implants rather than patients. The current study, with its patient group randomly selected from a real-world population, therefore adds considerable value to the field. The findings that patient- and implant-related factors influence the risk of moderate\/severe peri-implantitis could inspire future work to investigate the reasons for this. With peri-implantitis potentially leading to loss of implant and entailing inconvenient and uncomfortable treatment, this work could have a valuable impact on the lives of patients.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>","protected":false},"excerpt":{"rendered":" Peri-implantitis is a major and growing problem in dentistry, necessitating inconvenient and uncomfortable treatment for the patient and using valuable dentists' resources. <\/p>","protected":false},"featured_media":1969,"template":"","article_cat":[23],"acf":[],"_links":{"self":[{"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/article\/1814"}],"collection":[{"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/article"}],"about":[{"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/types\/article"}],"version-history":[{"count":16,"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/article\/1814\/revisions"}],"predecessor-version":[{"id":2177,"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/article\/1814\/revisions\/2177"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/media\/1969"}],"wp:attachment":[{"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/media?parent=1814"}],"wp:term":[{"taxonomy":"article_cat","embeddable":true,"href":"https:\/\/aid-foundation.com\/en\/wp-json\/wp\/v2\/article_cat?post=1814"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Insights from this study for clinical practice<\/strong><\/h4>\n\n\n\n
