title: Prevalence of peri-implant disease on platform switching implants: a cross-sectional pilot study.
abstract: The objective of this study was to assess the prevalence of mucositis and peri-implantitis associated with the use of two types of implants-conventional versus platform switching after one year of loading. A longitudinal study of 64 implants in 25 patients was performed. Clinical variables, such as clinical pocket depth and bleeding upon probing, plaque, mobility, gingival recession, clinical attachment loss, and radiographic bone loss, were analyzed. The case definition for peri-implantitis was established as pockets of ≥ 5 mm with bleeding and bone loss ≥ 2 mm. One year after implant loading, the prevalence of mucositis and peri-implantitis with conventional implants (CIs) was 81.2% and 15.6%, respectively. For platform switching implants (PSIs) the prevalence was 90% and 6.6%, respectively. These differences were not statistically significant (p = 0.5375). However, there was a trend towards a lower prevalence of peri-implantitis with platform switching Implants.
