摘　　要：目的研究Spee曲线深度与牙弓形态之间的关系。方法将150例18~25岁的维吾尔族人分为男女两组,其中男62例,女88例,利用计算机软件测量Spee曲线深度,尖牙间宽度,磨牙间宽度,牙弓长度。结果 Spee曲线深度与性别因素无关;左右侧Spee曲线深度存在统计学意义;牙弓形态受性别因素影响,却与Spee曲线深度不存在关联。结论临床上,Spee曲线深度可当一个参考平面辅助咬合重建以及正畸治疗。Objective To evaluate the relationship between the depth of the curve of Spee and dental arch morphology. Methods150 Uygur adults（ 62 males and 88 females） between the age of 18 and 25 were selected and divided into two groups. Dental casts of all subjects were taken. By means of computer software,the depth of the curve of Spee,the width of the cusp tips of the canines,the width of the cusp tips of the molars and the length of dental arch were measured. Results The depth of the curve of Spee was not affected by sex,there was significantly statistical difference between the depths of the left and the right curve of Spee of the identical individual.Dental arch morphology was affected by the gender factors,but not influenced by the depth of the curve of Spee. Conclusion In clinical practice,the depth of the curve of Spee can be used as a reference plane for occlusal reconstruction and orthodontic treatment.
