ABSTRACT
Osseointegrated implants are a form of therapy that is finding increasing application in dental treatment. Long-term success can be ensured if the results of recall examinations are systematically documented. Life table analyses are being used to a growing extent to ensure objective assessment of the success of osseointegrated implants. With the help of the statistical method designed by Kaplan-Meier and Cutler-Ederer in 1958, the survival time of the implant can be calculated and the relationship between various covariables and the service time of the implants can be determined. This study calculates the success potential of 683 osseointegrated implants (IMZ and Brånemark) using the customary input-output statistics and life table analyses to explain the discrepancy between the two statistical methods, based on the results obtained.

The results of clinical examination, orthopantomographic examination and computed tomography were compared in 55 patients with impacted teeth. The results of computed tomography and orthopantomograms were equally good. Both methods were superior to clinical examination. With regard to the detection of displacement, contact and resorption, computed tomography was superior to both clinical examination and orthopantomograms.
