Table 4 Morphologic adaptation of TMJ (short-term)

From: Effect of protraction facemask on the temporomandibular joint: a systematic review

Author Outcome 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.
