A longitudinal microbiological study on osseointegrated titanium implants in partially edentulotis patients

摘要: The aim was to longitudinally follow the colonization of putative periodontal pathogens on titanium implants in partially edentulous patients. Nineteen individuals, who were and waiting-list be treated with fixtures, included study. They for disease oral hygiene instructions supra- subgingival debridement left maintenance. Full-mouth recordings each patient performed at baseline, including attachment level probing pocket depth. Bleeding provoked visible plaque registered. Subgingival samples taken examination Porphyromonas gingivalis, Prevotella intermedia Actinobacillus actinomycetemcomitans. Bridge connection completed 1 month after abutment connection. bone registered radiographs. patients followed clinical registrations 6, 12, 24 36 months. No significant changes depth, level, bleeding or score occurred during experimental period. number individuals positive teeth abutments various bacterial species reached approximately similar levels 6 over time seen. Comparison between height, seen radiographs, 2, 12 months gave only 3 sites loss > 0.5 mm. All these found one accompanied by P. intermedia.
