Introduction: Recently, the number of implants placed worldwide has increased
tremendously, so as the prevalence of peri-implant complications. Objective: To
determine the prevalence of peri-implant diseases and technical complications of the
implant-supported single crown (ISC) in Kedah. The characteristics of patients and
implants associated with the peri-implant diseases were also explored. Materials and
methods: All patients received an ISC between January 2008 and December 2016 at a
public periodontal clinic and had a loading time between 2 and 10 years were identified.
The medical and radiographic records were reviewed. A patient and implant-based
prevalence analysis of peri-implant disease and complications were conducted. Results:
Twenty-three patients with a total of 43 implants were included in the analysis. The
majority (69.6%) of patients were aged under 65 years old. The prevalence of peri-
mucositis and peri-implantitis were 30.4% which involved 20.9% and 18.6% of the
implants respectively. Poor oral hygiene at the last follow-up visit showed a significant
association with the peri-implant diseases. However, the roles of the implant’s
characteristics were insignificant. No implant insertion failure was reported following
the placement of supra-structure, while 3 implants (7%) were having technical
complications. Conclusion: As the poor plaque control shown to be a risk factor of peri-
implant diseases, strategies to improve oral hygiene awareness and practice are
warranted.
