Sažetak
Objectives To assess whether implant macrodesign parameters interacting with implant time in function (Tf) could infuence the peri-implantitis occurrence. Materials and methods One hundred and two patients (55.17±11.2 years old) with diagnosed early/moderate peri-implantitis around endosseous implants with implant-supported prosthetics reconstruction (n=139) were recruited. Implant macrodesign (implant shape, thread number, implant collar), clinical parameters (peri-implant probing depth (PPD), clinical attachment level (CAL), keratinised tissue width (KTW), plaque index, bleeding on probe), implant placement localisation and region, and Tf were assessed and compared. Results Peri-implantitis occurred approximately 6.1±3.38 years after implant loading. There was a signifcant positive correlation between the implant macrodesign and Tf. Peri-implantitis rates were statistically signifcantly higher in implants with a cylindric shape and triple-thread in the posterior part of the mandible (p=0.037 and 0.012, respectively). The thread number and implant shape interacting with Tf showed statistically signifcant infuences on CAL and PPD increase (p<0.05). Results indicated a statistically positive interaction between Tf and KTW decrease around the implants with microthreaded collar (p<0.001). Conclusion Peri-implantitis might be presented as a time-dependent disease. Implant- based factors, such as Tf and implant macrodesign, could infuence peri-implantitis occurrence, exacerbate clinical parameters, and promote progressive bone loss. Clinical relevance Peri- implantitis can be afected by implant macrodesign and Tf. The implant body shape, thread number, and design of the implant collar may be considered peri-implantitis-related risk indicators that should be taken into account in proper implant planning and therapy
