Implants are permanent titanium posts that are anchored to the maxilla and mandible and are further topped with an individual crown or bridge. After implants are placed, a 4 to 8 month osseointegration period occurs between the implant and the bone of the mandible or maxilla. Osseointegration of dental implants is dependent on a multitude of conditions such as implant design, patient related medical risk factor, and surgery related factors. Although 5 year dental implant success rates have been shown to be between 90 and 95% high risk groups for dental implant failure have to be established to guide the practitioner in the appropriate treatment planning process.

Conclusion Female patients older than 50 years old who obtained Straumann dental implants were at highest risk of dental implant failure. Methods 250 patients were analyzed in a retrospective review to determine the rate of dental implant failure and the factors associated with dental implant failure for dental implants placed at the University of Louisville between 2008 to 2013. Patient data such as patient age, gender, co-morbidities, diabetes, placement in mandible or maxilla, placement in anterior or posterior teeth, dental implant manufacturer, bone graft placement, and implant success was collected. A chi-square and logistic regression analysis was performed to determine which factors were statistically significantly associated with dental implant failure. References Rocchietta I, Nisand D.
