Abstract
|
|
|
Statement of the problem: Implant systems result in gaps and cavities between implant and abutment that can act as a trap for bacteria and thus possibly cause inflammatory reactions in the peri-implant soft tissues.
Purpose: Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia, Treponema denticola, and Aggregatibacter actinomycetemcomitans, related to implant-abutment interface microleakage.
Material and methods: Samples were taken from 27 subjects with sterilized paper points and were transported in 1×PBS. The detection of periodontopathogens were performed by polymerase chain reaction with species-specific primers based on 16S rDNA.
Results: Our data showed that the detection rate of P. gingivalis and P. intermedia in implant fixture was 59% and 82% in patients respectively. Detection rate of P. gingivalis and P. intermedia in implant crevice was 44% and 82% in patients. Detection rate of P. gingivalis and P. intermedias in tongue was 82% and 82% in patients.
Conclusion: Current implant systems cannot safely prevent microbial leakage and bacterial colonization of the inner part of the implant.
