T1 (1 year), T2 (5 year), FM (facemask), MP (mentoplate). Results are described in median ± standard deviations. Intergroup comparison is performed using unpaired two-sided samples t-test, *: p < .05.

(T0 was subtracted from T1; T0 was subtracted from T2 and T1 was subtracted from T2. This means that a positive value indicates more protrusion whereas a negative value indicates retrusion).
