Introduction: It is important to provide all the necessary information regarding the
implant procedure, its predictability and survival rates during the informed consent process
for the patient’s consideration and for the clinician to understand what makes the implant
treatment last longer which brings great satisfaction for the patient. Objectives: To assess
the survival function of the dental implant placed in Periodontics Clinic, Hospital Universiti
Sains Malaysia (HUSM) from the time of implant placement until re-evaluation, and to
determine the associated factors of implant survival. Materials and methods: This was a
retrospective study involving 12 patients with 17 dental implants conducted in
Periodontics Clinic, HUSM. The data was retrieved when the implant was placed from the
year 2008 to 2014, and the patient was re-evaluated in the year 2019. Information on
implant status and covariates were retrieved from dental records and updated during the
final re-evaluation when the study was conducted. This study was very specific in
categorizing the implant status based on peri-implant health with possible association to
covariates. All data were collected and analysed using SPSS Version 27 for descriptive
analysis and survival analysis. Results: There were equal number of male and female
respondents with seven Malays, four Chinese, and one Indian respondent. 41% have
diabetes mellitus and hypertension whilst 25% have cardiovascular. 66% of respondents
had good oral hygiene, and 33% of respondents had poor oral hygiene. There were 41%
non-periodontitis patients and 58% periodontitis patients. 58% of respondents came for
regular follow-up 6-monthly. The longest observable time duration for the implant with
satisfactory survival from the time of implant placement until re-evaluation when the
study was conducted was 121 months. The first occurrence of compromised events was
th
observed at the 30 month. Only covariate oral hygiene was significantly associated with
the survival function of the implant (P-value = 0.01). Professional maintenance recall was
not statistically significant but was considered clinically significant to reinforce the oral
hygiene of the patient. Conclusion: Among all covariates, only oral hygiene showed a
statistically significant association with the survival function of the dental implant.
However, personalized professional maintenance care is considered clinically important
to improve personal oral hygiene and intercept any infection earlier. Interpret these
results with caution due to the small sample size.
