Abstract:

STUDY OBJECTIVE

: to assess the morphological changes in the mandibular condylar processes during functional remodeling after bimaxillary orthognathic surgery in patients with Class II skeletal malocclusion.

MATERIAL AND METHODS

The study analyzed 30 3D models of mandibular condyle (MC) obtained from computed tomography scans of patients (n=15), conducted 1 week before and 12 months after bimaxillary orthognathic surgery (T1 and T2, respectively). The analysis included a comparison of the volumes of the 3D MC models at T1 and T2, as well as measuring the T1—T2 distances of the 3D MC models at the poles of five surfaces (superior, anterior, posterior, medial, and lateral). A correlation was determined between the extent of maxillomandibular advancement (MMA), counterclockwise rotation of the occlusal plane (CCWROP), and morphological changes in the MC.

RESULTS

A decrease in MC volume was observed postoperatively, averaging 14.5% (p<0.001). T1—T2 distance changes showed more pronounced remodeling with a reduction in the distance between the poles on the superior and posterior surfaces of the MC compared to the other surfaces. However, the lack of differences in all paired comparisons of changes in intersurface distances of the 3D MC models at the poles of the five surfaces at T1 and T2 (p>0.05) indicates uniform volume reduction in the MC. No correlation was found between morphological changes in the MC and the degree of MMA or CCWROP. Morphological changes in the MC at T2 were not accompanied by clinical manifestations in the temporomandibular joint (TMJ).

CONCLUSION

Morphological changes in the MC after bimaxillary orthognathic surgery with MMA in patients with Class II skeletal malocclusion are within the range of functional remodeling, do not lead to TMJ dysfunction or occlusal disturbances. However, the reduction in MC volume approaches the threshold values for condylar resorption.
