Factors associated with crestal bone gain on single-tooth locking-taper implants: the effect of nonsteroidal anti-inflammatory drugs.

摘要: PURPOSE To identify factors associated with crestal bone gain around single-tooth implants. MATERIALS AND METHODS A retrospective cohort study was conducted. More than 90 different local and systemic were documented. Descriptive statistics univariate multivariate mixed-effects regression models, adjusted for multiple implants in the same patient, used to predictors of after insertion definitive restorations. RESULTS Eighty-one subjects who received 326 Bicon followed an average 70.7 months. 46 patients showed varying degrees apparent over time. Variables peri-implant first model were: type opposing structure, tooth (P = .02); restoration, crown cemented on a prefabricated titanium abutment spherical base .006); hydroxyapatite coating .0005); implant size 5 x 8 mm daily intake nonsteroidal anti-inflammatory drugs (NSAIDs) =.04). NSAIDs remained significantly correlated second analysis; more likely if patient taking .02), but this effect specific hydroxyapatite-coated .01). CONCLUSION Daily doses significant increase levels following insertion.
