摘　　要：本文报道1例于广州医科大学附属口腔医院完成的成人安氏Ⅰ类错[牙合]伴17/47锁[牙合]的病例。本例患者存在磨牙段锁第二磨牙锁[牙合],矫治难度大,不恰当的垂直向控制容易引起侧貌恶化。在患者上颌第二磨牙远中腭侧区植入微种植体,以拉簧使矫治装置产生远中、腭向及垂直向压低的矫治力。治疗3个月后即解除第二磨牙锁[牙合]。该法不仅保护了上颌磨牙支抗,并且有利于面高的控制。因此,该方法是矫治第二磨牙锁[牙合]的有效方法。A case of adult ClassⅠmalocclusion with scissor bite of 17/47 from Affiliated Stomatology Hospital of Guangzhou Medical University was reported.The patient in this case has molar scissor bite,which is difficult to correct,and improper vertical control is easy to cause the deterioration of the profile.Mini-screw were implanted in the distal palatine region of the maxillary second molar of the patient,and tension springs were used to produce distal,palatine and vertical compression of the appliance.The scissor bite of the second molar was corrected after three months of treatment,this method not only protects the maxillary molar anchorage,but also helps to control the face height.Therefore,this method is an effective method to correct the scissor bite of the second molar.
