Abstract
This 3-year retrospective follow-up study was conducted to evaluate longitudinal changes in periimplant sulcus depth (PISD) and findings of the Periocheck diagnostic (PCD) tests. A total of 61 people participated in the latest of this series of trials. They were comprised of 16 males (mean age: 65.1±9.3 years) and 45 females (mean age 58.2±9.0 years). The number of subjects who revisited three times consecutively was 59. All the subjects underwent oral implant surgery 4 to 24 years ago.
The results of the tests performed on the 3rd year trial revealed that as high as 86.9% of the subjects had PISDa, but did not show any significant change in the PCDo and PCDb evaluations associated with PISD variations. From the relationships between PCD evaluation and PISD measurement,even the subjects with PISDa were found to have PCDo and PCDb. There were no significant differences in values between 4 major factors. However, significant differences in mean PISD values were observed between sub-factors. Changes during the period of three years were diverse in males, “unchanged type,”“recovery type,”“unstable type,”and “deteriorating type.”While in 55.9% of the females,“unchanged type”was observed. Changes in mean values and occurrence rates during the period were insignigicant.
The findings suggested that both tests like the peri-implant sulcus depth and the Periocheck as well as instruction on oral hygiene and daily life guidance should be introduced as clinical routine in order to obtain better clinically stability results.
