20年来Twin-block功能矫治器用于临床矫治安氏Ⅱ~1错(牙合)取得明显效果。近几年国内外学者就其对颌骨、颞颌关节及咀嚼肌影响方面的研究逐渐增多,与其它功能矫治器比较,均对Twin-block功能矫治器应用前景看好。认为该矫治器的临床效果明显,引起髁突、颌骨、牙槽骨及肌肉反应,功能刺激下引起颞颌关节的改建,但对是否促进或抑制颌骨生长,还存在不同见解,有待进一步探讨。 Twin-block appliance for 20 years for clinical treatment of Angle Ⅱ ~ 1 wrong (occlusion) achieved significant results. In recent years, domestic and foreign scholars on the jaw, temporomandibular joint and masticatory muscle effects increased gradually, compared with other functional appliances, Twin-block appliances are promising. It is considered that the clinical effect of this appliance is obvious, which causes the reaction of condyles, jaws, alveolar bone and muscle, and the remodeling of temporomandibular joint caused by functional stimulation. However, there are still different opinions on whether to promote or inhibit the growth of jaws. Discussion.
