In addition, the factors - influencing the survival time of the abutment teeth - as well as the nature and the number of the follow-up treatment measures were determined.The evaluation based on records of 84 patients who had been treated in the Department of Prosthetic Dentistry, Justus-Liebig-University Giessen, Germany.The 90%- (50%-) survival probability of the dentures was not achieved after 4.0 years (9.1 years). Furthermore, the 90%- (50%-) survival probability of the abutment teeth, determined at 4.0 years (12.9 years), was comparable to other studies. It was revealed, that the vital abutment teeth had a significant higher survival rate and survival time in comparison to abutment teeth, treated endodontically and provided with root canal posts.The patients' assessment of the telescopic crown retained denture was down the line positive (70% were very satisfied, 28% were relatively satisfied, 2% were dissatisfied).
