【摘要】：目的：对非综合征性单侧完全性唇腭裂(Unilateral complete cleft lip and palate, UCLP)患者牙(?)模型评价、测量分析,了解UCLP患者上下牙弓关系以及牙弓对称性。方法：实验一：对52例UCLP患者的全口牙(?)模型的上、下牙弓关系进行Goslon Yardstick等级评价,应用有序变量资料的秩和检验比较本中心UCLP患者等级结果与其他中心等级结果,以及本研究中替牙期与恒牙期UCLP患者的等级结果,评价UCLP患者的上下牙弓关系。实验二：从实验一中随机选取替牙期和恒牙期UCLP患者的牙(?)模型各15副,并以恒牙期个别正常(?)患者为对照,采用模型测量方法,测量UCLP患者裂侧和非裂侧(个别正常(?)患者为左侧和右侧)上牙弓和下牙弓各段宽度,计算牙弓各段非对称率,探讨UCLP患者牙弓对称性。结果： 1.52例UCLP患者中,60%的患者牙弓关系差,Goslon Yardstick等级均值为3.75： 2.替牙期和恒牙期UCLP患者中Goslon Yardstick等级结果及等级分布相近,差异无统计学意义(P0.05)； 3. UCLP患者除牙弓后段外,上牙弓和下牙弓其余各段不对称,且随生长发育,上牙弓前段非对称率增大(P0.05)；UCLP患者上、下牙弓各段非对称率高于个别正常(?)患者(P0.05)。 4.替牙期UCLP患者牙弓前段和中段非对称率在上、下牙弓间具有一定的相关性(P0.05),而恒牙期UCLP患者仅牙弓前段非对称率在上、下牙弓间具有一定的相关性(P0.05)。结论：UCLP患者上、下牙弓协调性差,牙弓对称性差。随生长发育,UCLP患者上牙弓前段不对称性加重,UCLP患者在某些牙弓区段上牙弓和下牙弓间对称性存在一定的相关性。
[Abstract]:Objective: to investigate the effects of unilateral complete cleft lip and palate (UCLP) in patients with non-syndromic unilateral cleft lip and palate. Model evaluation, measurement and analysis, to understand the relationship between upper and lower dental arch and dental arch symmetry in UCLP patients. Methods: experiment 1: 52 cases of UCLP patients with complete teeth? The relationship between upper and lower dental arch was evaluated by Goslon Yardstick grade. Rank sum test of ordered variable data was used to compare the grade results of UCLP patients in our center with those of other center grades, as well as the grade results of UCLP patients in the replacement period and the permanent period in this study. To evaluate the relationship between upper and lower dental arch in patients with UCLP. ) the models were 15 pairs each, and each of them was normal in the permanent tooth period. ) the cleft side and non-fissure side of UCLP patients were measured by model measurement. ) the width of the upper and lower arch segments was calculated and the asymmetry rate of the arch segment was calculated to investigate the dental arch symmetry in patients with UCLP. Results:. 1.The mean value of Goslon Yardstick grade was 3.75 in 60% of patients with UCLP. 2. The results and distribution of Goslon Yardstick grade in patients with UCLP were similar, but there was no significant difference between them (P 0.05). 3. The asymmetry rate of the upper arch and the lower arch in UCLP patients was higher than that in the individual normal dental arch. The asymmetry rate of the anterior segment of the upper arch increased with the growth of the upper arch and the other segments of the lower arch, and the asymmetry rate of the anterior segment of the upper arch was higher than that of the individual normal dental arch. ) patients with P0.05N. 4. The asymmetrical rate of anterior and middle segments of dental arch was higher in UCLP patients, and there was a certain correlation between lower arch and anterior segment of dental arch, while in permanent stage of UCLP, the asymmetry rate of anterior segment of dental arch was higher than that of lower arch, and there was a certain correlation between lower arch and anterior segment of dental arch. Conclusion there is a certain correlation between the asymmetry of upper arch and lower arch in UCLP patients with UCLP and the asymmetry of upper arch and lower arch in UCLP with the development of UCLP.
