Abstract
PURPOSE: To explore the incidence of peri-implantitis (PI) and peri-implant mucositis (PM) during 15 years of implant placement.
METHODS: A retrospective analysis of 507 patients (1 162 implants in total) who underwent oral implant restoration in the Affiliated Stomatological Hospital of Nanchang University from January 2001 to December 2005 were performed and followed up for 12-15 years. The clinical data of the patients were collected, and the individual and implant-level PI, PM incidence and influencing factors were analyzed. SPSS 22.0 software package was used for statistical analysis.
RESULTS: After an average of 13.37 years of follow-up, the overall incidence of PM and PI in 507 implant restoration patients was 45.0% and 9.7%, respectively. The incidence of PM and PI in 1 162 implants was 44.1% and 10.9%, respectively. Among 127 implants with PI, there were 8 implants (6.3%) failed. PI had a low incidence within 0.5 to 1 year after implantation and restoration, with a significant increase in incidence within 1 to 5 years, a decrease in incidence within 5 to 10 years, and a continuous decrease in incidence over 10 years. The incidence of PM was relatively high within 0.5-1 year of implantation and restoration, gradually decreased in 1-5 years, and remained basically unchanged for 5-10 years and more than 10 years. The incidence of PI and PM using Straumann system was the lowest, and the incidence of Osstem system was the highest (P<0.05). The incidence of PI and PM in the upper anterior tooth area was significantly higher than that of other teeth(P<0.05). The probability of PI and PM was the highest in patients with non-closed crown edges, followed by loose abutment screws, loose crown-retained screws, and broken abutment screws(P<0.05). Multivariate logistic regression analysis showed that implantation time, implant system, implant position, and restorative factors were high-risk factors affecting the incidence of PM and PI (P<0.05).
CONCLUSIONS: The incidence of PM is widespread within 15 years of implant placement. The incidence of PI does not increase with the increase of restoration time, but is related to implantation time, implant system, implant position and later restoration factors.
