Figure 1 Presentation of the clinical survival rates depending on the chosen treatment concept within the patient groups.
Figure 2 Clinical success rate of all included roots depending on the tooth position. Mean follow-up intervals = 17.5 months for anterior teeth, 14.2 months for premolars and 13.5 months for molars.
