    Journal: Shanghai Kou Qiang Yi Xue; 2011 Aug; 20(4):409-12. PubMed ID: 21909609.
    Abstract:
    PURPOSE: To evaluate quantitatively the effect of semi-fixed Twin-block appliance on the temporomandibular joint remodeling during the Class II malocclusion treatment. METHODS: Twenty two Class II division 1 patients treated with semi-fixed Twin-block appliance were included. Pre- and post-orthopedic treatment cephalometric data were analyzed with SPSS13.0 software package for paired t test. RESULTS: The mandibular condylar growth was directed superiorly(2.7mm) and posteriorly (3.6mm) (P<0.01), the glenoid fossa was displaced in a inferior(1.5mm) (P<0.01) and posterior (0.8mm)(P<0.05) direction, the effective TMJ changes showed a pattern similar to condylar growth in a superior(4.2mm) and posterior(2.7mm) direction(P<0.01), the mandibular rotation was slightly clockwise(P>0.05). CONCLUSIONS: The application of semi-fixed Twin-block appliance shows its effectiveness on patients' compliance and the remodeling in temporomandibular joint, contributing to the correction of sagittal jaw relationship discrepancy.
