About

The purpose of this prospective clinical trial is to investigate and identify factors associated with the failure of dental implants within the population rehabilitated with dental implants at the Folktandvården Specialistklinik in Malmö (Spårvägsgatan 12, 214 27, Malmö).

Full description

The treatment begins with screening against inclusion and exclusion criteria. The patients will then be informed of the design of the study through the reading of the Form for Patient Information and the Informed Consent in Swedish and verbally.

All dental implants to be inserted will be included in the study. Some surgical, implant, loading, prosthetic variables of the study will be decided according to the surgeon's criteria and patient's decisions.

Data will be collected in specific forms, and will be categorized as surgical, implant-specific, patient-related, anatomic, loading conditions, prosthetic, and complications.

Besides descriptive statistics, Kaplan-Meier analysis will be used to estimate implant survival/failure rates (an estimator for estimating the survival function from lifetime data), and multivariate Cox proportional hazards models will be used to identify prognostic variables.
