Mesial Distal Mesial Distal
T1 –0.44±0.62 0.35±0.72 - -
T2 0.14±0.66 –0.27±0.52 0.30±0.52 –0.71±0.78

1Mean MBL at T1, T2, T3, and T4 significantly changed compared with that at installation (P<0.05).

2Mean MBL at T2 was significantly higher than at T3 and T4. Mean MBL at T3 was significantly higher than at T4 on the distal side. Mean MBL at T3 and T4 did not differ significantly on the mesial side (P<0.05).
