目的：比较骨性Ⅱ类前牙开牙合患者不同垂直骨面型磨牙高度及切牙代偿的差异。方法：选择40例骨性Ⅱ类前牙开牙合及20例成年正常牙合为研究对象，根据SN／MP角和FH／MP角将开牙合患者分为高角开牙合组（23例）和均角开牙合组（17例），比较高角、均角开牙合与正常牙合对照组之间磨牙高度及切牙代偿情况。结果：①、前牙开牙合组磨牙高度均大于正常牙合组（P＜0．01）。②、高角开牙合组下颌磨牙高度大于均角组（P＜0．05）。③、高角组上切牙唇向倾斜度小于均角开牙合组（P＜0．05）。④、均角开牙合组下切牙唇倾度大于高角组（P＜0．01）。结论：不同垂直骨面型骨性Ⅱ类前牙开牙合患者磨牙高度代偿过度及上下切牙唇舌向代偿有差异，矫治中应结合不同垂直骨面型磨牙高度和切牙代偿情况，明确去代偿或代偿潜力。
目的：比較骨性Ⅱ類前牙開牙閤患者不同垂直骨麵型磨牙高度及切牙代償的差異。方法：選擇40例骨性Ⅱ類前牙開牙閤及20例成年正常牙閤為研究對象，根據SN／MP角和FH／MP角將開牙閤患者分為高角開牙閤組（23例）和均角開牙閤組（17例），比較高角、均角開牙閤與正常牙閤對照組之間磨牙高度及切牙代償情況。結果：①、前牙開牙閤組磨牙高度均大于正常牙閤組（P＜0．01）。②、高角開牙閤組下頜磨牙高度大于均角組（P＜0．05）。③、高角組上切牙脣嚮傾斜度小于均角開牙閤組（P＜0．05）。④、均角開牙閤組下切牙脣傾度大于高角組（P＜0．01）。結論：不同垂直骨麵型骨性Ⅱ類前牙開牙閤患者磨牙高度代償過度及上下切牙脣舌嚮代償有差異，矯治中應結閤不同垂直骨麵型磨牙高度和切牙代償情況，明確去代償或代償潛力。

Objective:The purpose of this study was to compare molar heights and incisor inclinations in skeletal ClassⅡ open bite adults with different vertical skeletal patterns,Provide a certain guiding for clinical diagnosis and treat-ment. Method:40 adults with skeletal class Ⅱopen bite and 20 adults with adequate overbite were examined and divided in-to three groups according to vertical skeletal patterns:the classⅡanterior open bite with high mandible angle group(n=23);the class Ⅱanterior open bite with low mandible angle group(n=17);the class Ⅰnormal overbite control group(n=20). Pre-treatment Lateral cephalometric radiographs were taken. The molars height and the incisor positions were evaluated. Multi-variate analysis of variance tests were used to determine the differences between the groups. Result:Significant differences in molar height were found(P<0.01) between the anterior open-bite group and the control group,Mandibular molar height was greater in the classⅡanterior open bite with high mandible angle group (P <0.05). Maxillary incisor to SN angulation was greater in the anterior open bite with high mandible angle group (P <0.05) of the three group. Mandibular incisor to mandibular plane angulation was more buccal inclinations in the anterior open bite with low mandible angle group(P<0.01). Conclusion:molar heights and incisor inclinations in skeletal ClassⅡopen bite adults are different with vertical skeletal pat-terns.
