Dental‐implant inflamed surface area: A quantification and simulation study

Peri-implantitis is a common gum disease surrounding dental implants. Although recent guidelines help diagnose it, there's still no clear way to measure the inflammation surface area around implants. We developed formulas to calculate the dental-implant surface area (DESA) and compared them for different implant shapes using data on pocket depth, gum recession, and implant type. We then calculated the dental-implant inflamed surface area (DISA) by multiplying the tissue area around the implant by the proportion of bleeding sites. In our study, we included data from 10,000 implants to test the new scores. The DESA score was very accurate, underestimating the real surface area by < 2%. We then used the DISA score on 21 patients with peri-implantitis. The DESA scores ranged from 54.24 to 400.29 mm², while the DISA scores ranged from 36.76 to 400.29 mm². In conclusion, we introduced two new scores (DESA and DISA) to measure the inflammation caused by peri-implantitis. These scores could help in better diagnosing and treating peri-implantitis, with future research exploring their link to overall health.
