摘　　要：目的:探讨中重度牙列拥挤非拔牙矫治的临床效果。方法:选择面型较好、牙列拥挤度在5～10 mm的病例14例,进行方丝弓或直丝弓非拔牙矫治,非拔牙矫治的方法包括推磨牙向远中、扩大牙弓、唇向开展前牙和邻面去釉。术前术后均拍摄X线头影测量片进行分析。结果:采用非拔牙矫治的14例中重度拥挤患者经固定矫治器治疗后均达到满意的治疗效果,牙齿排列整齐,咬合关系正常,面型良好。结论:中重度牙列拥挤非拔牙矫治是可能的,应行综合分析决定矫治方案。Objective： To evaluate the clinical effectiveness of non - extraction treatment for patients with mild to severe crowding. Methods ： 14 cases with good soft tissue profile and ranging from 5 to 10mm crowding were collected. We chose non - extraction treatment. All patients were treated with edgewise appliance or straight wise appliance. The methods of non - extraction treatment include moving upper molars distally, dental arch expansion, maxillary protraction, anterior lip inclination and interproximal stripping. The cephalometric films before and after therapies are measured and compared. Results： 14 cases of nonextraction treatment all achieved satisfactory treatment results, good occlusal relationship and soft tissue profile. Conclusion ： If we can decide treatment methods through comprehensive analysis ,non - extraction treatment of patients with mild to severe crowding will be feasible.
