Table 3.

Clinical outcomes on patient level for both implant systems (AST and STM) at the time of loading (TL), and at the 10-year (T10) follow-up examination with the respective changes over time. Patient level analysis with means, standard deviations (SD), medians, first and third quartile (Q1, Q3), range from minimum to maximum for both implant systems. BOP: bleeding on probing; PCR: plaque control record; PD: probing depth. Calculations of p- values for the patient level analysis were performed with the Wilcoxon signed rank test for the intragroup comparison and the Wilcoxon test for the intergroup comparison
