The effect of single tooth implant restorations on the survival, morbidity, pulpal, and periapical health of adjacent teeth: A chart review (original) (raw)

To determine whether the placement and restoration of a single tooth posterior implant affects the survival, morbidity, pulpal, and periapical health of adjacent natural teeth. A retrospective chart review identified patients who received single posterior tooth implants between August 2004 and July 2015 at the UNC SOD and met the study inclusion criteria. Preoperative and postoperative records were reviewed; survival and changes in coronal, pulpal, and periapical status of teeth adjacent to the implant and contralateral tooth were recorded. Dichotomous survival, restoration, and retreatment outcomes were analyzed using conditional logistic regression with patient as strata and implant versus control as the predictor. Exact odds ratio estimates and the 95% confidence intervals were obtained for the relationship of implant versus control side and outcomes. Five hundred and fifty-five sites with follow-up time averaging 5 years ± 30.8 months were reviewed. Teeth adjacent to implants ha...
