AID Practical Impact Award 2026: A Long-Term Comparison of Bone-Level and Tissue-Level Implants (english version)<\/h1>\n\n\n

What role does implant design play in long-term peri-implant health? Dr. Emilio Couso-Queiruga and Dr. Clemens Raabe explored this question through follow-up examinations conducted an average of eleven years after implant placement.<\/strong><\/em><\/p>\n\n\n\n

Bone\u2010Level Versus Tissue\u2010Level Titanium Dental Implants: A Comparative Cross\u2010Sectional Study.<\/em><\/a><\/p>\n\n\n\n

Z\u00fcrich, October 2026 <\/strong>\u2013 The Alliance for Implant Dentistry (AID) honored Dr. Emilio Couso-Queiruga and Dr. Clemens Raabe with the Practical Impact Award 2026. The award recognizes their comparative study of bone-level and tissue-level implants, which assessed implant survival as well as peri-implant diseases and associated factors.<\/p>\n\n\n\n

With this award, AID recognizes scientific work for its scientific quality, with particular emphasis on its high clinical and practical value for implant dentistry.<\/p>\n\n\n\n

In their single-center cross-sectional study, the research team at the University of Bern investigated whether bone-level and tissue-level implants in anterior and premolar sites differ in their long-term outcomes with respect to implant survival and peri-implant diseases. Implant diameter and other potential risk indicators were also considered.<\/p>\n\n\n\n

The study included 266 patients with an initial total of 336 implants, with follow-up examinations conducted an average of 11 years after implant placement. Following the loss of four implants, 332 implants were available for peri-implant tissue assessment: 166 bone-level and 166 tissue-level implants. Both types showed high survival rates of 99.4% (bone-level) and 98.2% (tissue-level).<\/p>\n\n\n\n

Contrary to the initial hypothesis that peri-implant diseases would be more prevalent around bone-level than tissue-level implants, no statistically significant overall difference in the prevalence of these diseases was observed between the two implant designs. Peri-implantitis was present at 11.4% of bone-level and 9.0% of tissue-level implants.<\/p>\n\n\n\n

Interesting differences emerged in relation to implant diameter and tissue thickness: implants with a diameter of 3.3 mm showed a lower prevalence of peri-implantitis than those with a diameter of 4.1 mm (7.2% vs. 13.3%). The risk was particularly low when a narrow diameter was combined with a tissue-level design. In this group, the peri-implantitis rate was 4.8% (compared with 9.6% for narrow-diameter bone-level implants). Greater peri-implant mucosal thickness was associated with a lower prevalence of mucositis and peri-implantitis. Both diseases were more common at higher plaque scores, while peri-implantitis was more common among smokers.<\/p>\n\n\n\n

Dr. Clemens Raabe and Dr. Emilio Couso-Queiruga offer a clinical perspective on the findings:<\/p>\n\n\n\n

We were surprised that bone-level implants did not show a higher risk of disease over the long term. Carefully designed restorations, alongside ideal three-dimensional implant positioning, may have contributed to this finding, since this is a particular area of risk for bone-level implants. Evidence for the influence of a well-designed emergence profile on peri-implant health continues to grow. Our findings did, however, confirm how strongly patient factors and soft tissue shape the outcome<\/em>.<\/p>\n<\/div><\/div>\n<\/div>\n<\/blockquote>\n\n\n\n

The study provides valuable data on peri-implant health an average of eleven years after implant placement. Its cross-sectional design identifies associations but does not allow conclusions about cause and effect. The findings relate to a single implant system with two diameters used at non-molar sites. To verify the findings and assess their generalizability, the researchers recommend larger, more diverse patient cohorts and longitudinal studies involving multiple implant systems.<\/p>\n\n\n\n

AID congratulates Dr. Emilio Couso-Queiruga and Dr. Clemens Raabe, along with the research team, on receiving the award. Their work provides additional data for the long-term assessment of both implant designs and highlights why peri-implant health, alongside implant survival, is a central component of long-term patient care.<\/p>\n\n\n\n
