Sažetak
The etiopathogenesis of dental implant failure is multifactorial and may include
numerous local and systemic factors, however, studies including both local and systemic factors are still
lacking. Therefore, the aim of this study was to evaluate whether periodontal disease, oral hygiene
index,
i.e. bleeding on probing (BOP), full mouth plaque index (FMPI), smoking, systemic diseases,
as well as implant characteristics (length and diameter) affect failure of implant-prosthodontic therapy.
Data on 670 patients were retrieved in whom 1260 dental implants had been placed and followedup
for at least five to ten years. Categorical data were analyzed by the χ2-test, whereas Mann-Whitney
test was used for continuous variables (age, BOP and FMPI). The values of p<0.05 were considered
significant. The effect of local and systemic factors on the success of implant-prosthodontic therapy
was assessed by multiple logistic regression analysis. Forty-five (6.7%) patients had systemic diseases,
of which diabetes mellitus was most common, followed by atherosclerosis, diabetes and atherosclerosis,
diabetes mellitus type 1, lymphoma, and hepatitis C. One-third (33.4%) of the patients were
smokers. Periodontal disease was present in 170 patients, while 500 patients were without periodontal
disease. Nine implants were lost during the period of five years. There were no differences regarding
the type of implant or type of connection to the prosthetic suprastructure. However, most of these
patients had a periodontal disease. There were no significant differences in dental implant failure rates
between smokers and non-smokers or between patients with and without systemic diseases. Furthermore,
the results of this study showed that implant type (straight vs. tapered) and type of connection
with prosthodontic appliance (cemented or screw retained) did not affect BOP and FMPI. In smokers,
significant improvement of BOP and FMPI was noticed. Initially, smokers had a significantly
worse BOP (0.0037) when compared to non-smokers; however, there were no differences regarding
FMPI (p=0.4218) between the two groups. In patients with periodontal disease, improvement of
BOP and FMPI was seen at 5-year follow-up and no significant differences were found when compared
to patients without periodontal disease. There were no significant differences in BOP and FMPI
between patients with and without diabetes at 5-year follow-up. Atherosclerosis had a significant
negative effect on BOP, but not on FMPI at 5-year follow-up. It is concluded that periodontal disease
had a significant impact on the implant-prosthodontic therapy.
