  • Product Description

The purpose of this study was to determine the magnitude of the skeletal and dental movements in subjects with different facial patterns following Class II correction using the Xbow® appliance. A retrospective sample of 134 subjects exhibiting Class II malocclusions was used. Subjects were categorized into three growth types according to pre-treatment cephalometric variables, which yielded 27 brachycephalic, 70 mesocephalic, and 37 dolichocephalic subjects. Dental changes induced by the Xbow® appliance included: proclination of the lower incisors (L1-MP 7.3-12.3°±1.0°), protrusion of the lower incisors (L1-APo 2.1-3.8mm±0.3mm), mesial movement of the mandibular first molar (5.5-6.9mm±0.7mm) and retrusion of the maxillary incisor (2.4-3.1mm±0.4mm). Retroclination of the maxillary incisor (U1-PP 0.2-0.8°±0.7°) and distal movement of the maxillary molar (0.4-0.7mm±0.3mm) were not significantly influenced by Xbow® treatment. Reduction of the skeletal Class II relationship was represented by a significant decrease of the Wits value (2.4-4.5mm±0.5mm) in all three groups. Skeletal correction must be validated by more than one cephalometric variable.
