Abstract: Aim: The aim of this 10‐year study was to compare the failure, success and complication rates between patients having lost their teeth due to periodontitis or other reasons. Material and methods: Fifty‐three patients who received 112 hollow screw implants (HS) of the ITI® Dental Implant System were divided into two groups: group A – eight patients with 21 implants having lost their teeth due to chronic periodontitis; group B – forty five patients with 91 implants without a history of periodontitis. One and 10 years after surgical placement, clinical and radiographic parameters were assessed. The incidences of peri‐implantitis were noticed over the 10 years of regular supportive periodontal therapy. Results: Success criteria at 10 years were set at: pocket probing depth (PPD)≤5 mm, bleeding on probing (BoP−, bone loss<0.2 mm annually. The survival rate for the group with a past history of chronic periodontitis (group A) was 90.5%, while for the group with no past history of periodontitis (group B) it was 96.5%. Group A had a significantly higher incidence of peri‐implantitis than group B (28.6% vs. 5.8%). With the success criteria set, 52.4% in group A and 79.1% of the implants in group B were successful. With a threshold set at PPD≤6 mm, BoP− and bone loss<0.2 mm annually, the success rates were elevated to 62% and 81.3% for groups A and B, respectively. Relying purely on clinical parameters of PPD≤5 mm and BoP−, the success rates were at 71.4% and 94.5%, and with a...
