Short-term effect

Baccetti (1999)

TPS analysis: the shape changes of condyle

A large compression horizontally in the mandibular condyle.

Baccetti (2000)

Cephalometric Analysis: CondAx- SBL, CondAx-ML.

Significant increase of CondAx- SBL; Significant decrease of CondAx-ML; A more upward and forward direction of condylar growth significantly.

Chang (2006)

TPS analysis: the shape changes of condyle

A compression horizontallyin the mandibular condyle.

Baccetti (1998)

Cephalometric Analysis: CondAx-SBL, CondAx-ML

Significant increase of CondAx- SBL, Significant decrease of CondAx-ML; A more upward and forward direction of condylar growth significantly.

Franchi (1998)

Cephalometric Analysis: the direction of condylion movement

Significantly upward and forward movement of Condylion in direction relative to the baseline Go-Pg; Significantly downward and forward movement of Condylion in direction relative to the baseline Go-Pg.

Franchi (2014)

TPS analysis: the shape changes of condyle

A vertical extension and horizontal compression was found in the mandibular condyle.

Lee (2016)

CBCT: mandibular and glenoid fossa changes

Bone absorption at the lateral wall of the anterior mandibular fossa; Bone apposition to the medial and right anterior walls in the glenoid fossa; Bone absorption at the posterior wall and superior wall of the glenoid fossa.
