  1. Values are reported in millimeters (mm). Outcomes were evaluated between second premolar and the first molar (P2-M1), at the furcation of the first molar (M1F) and between the first molar and the second molar (M1-M2). Insertion axes were traced passing through 3 landmarks: zero point (zeroP), 2 mm cranial to zeroP (− 2P), and 2 mm caudal to zeroP (+ 2P). Insertion axes were also traced at three different angulations (45°, 60°, and 75°) compared to the occlusal plane
