Effect of Forsus Appliances on the Jaws and Temporomandibular Joint in Patients during Late Peak Period
Objective The effect of the Forsus appliance on the morphological structure of the jaws and temporomandibular joints in patients during late peak period was studied by CBCT.Methods 42 patients with Class Ⅱ malocclusion during late peak period were selected,20 patients who underwent Forsus functional treatment were included in the experimental group,22 cases without functional treatment were included in the control group,and CBCT scans were performed before and after treatment.Results These differences between experimental group and control group were statistically significant:B-point advance[(3.00±1.46)mm,(-0.63±2.81)mm],change of ANB angle[(-1.76±0.82)°,(-0.75±1.06)°],change of mandibular fossa height[(-0.02±0.74)mm,(0.82±0.89)mm],change of inclination angle of articular tubercle[(-3.97±7.32)°,(4.11±5.25)°],change of apical height of condyle[(0.60±0.82)mm,(0.06±1.09)mm],change of coronal area of the apical condyle(15.82±9.46)mm2,(7.45±15.35)mm2]and change of occlusion plane angle[(0.75±2.12)°,(-0.55±1.64)°].Conclusion Forsus appliances can lead to anterior displacement of the mandible and alteration of the morphology of the temporomandibular joint,with the occlusal plane rotating clockwise after treatment.
