  1. AD angular deviation (degrees), ARE apex resection error (mm; -: longer than planned; +: shorter than planned), ODE osteotomy depth error (mm; -: deeper than planned; +: shallower than planned). In Case #11, two roots of the same tooth were treated. NA: in these cases, the given parameter could not be measured (see Results). aTwo roots of the same tooth were treated. Medians and corresponding confidence intervals were calculated from absolute values to express the degree of error regardless of its direction
