目的:探讨正畸结合牙体种植治疗先天缺失牙的临床效果。方法:抽取2017年1月至2019年6月山西省中西医结合医院收治的先天缺失牙患者70例，采用随机数表分为两组，每组35例。对照组仅实施牙体种植，观察组在牙体种植前6～18个月实施正畸治疗。比较两组种植成功率、牙齿咬合力、咀嚼功能及语言功能评分。结果:治疗后3、6、12个月，观察组牙体种植成功率均高于对照组(χn 2＝4.629、4.786、4.058，n P＝0.031、0.029、0.044)。观察组治疗后3、6、12个月的牙齿咬合力均高于对照组(n t＝8.265、4.585、3.722，n P＝0.001、0.001、0.001)。治疗后12个月，观察组咀嚼功能及语言功能评分均低于对照组(n t＝3.701、2.625，n P＝0.001、0.011)。n 结论:正畸结合牙体种植治疗先天缺失牙效果较好，可提高短期内种植成功率，改善牙齿咬合力，促进咀嚼和语言功能恢复。“,”Objective:To investigate the clinical efficacy of orthodontic combined with dental implant on patients with congenital tooth loss.Methods:A total of 70 patients with congenital tooth loss admitted to Shanxi Integrated Traditional Chinese and Western Medicine Hospital from January 2017 to June 2019 were selected and divided into two groups by random number table, with 35 patients in each group. The control group received dental implant only, while the observation group received orthodontic treatment 6-18 months before dental implant. The success rate of implant, bite force, scores of masticatory function and speech function of the two groups were compared.Results:The implantation success rate of the observation group at 3, 6 and 12 months after treatment were higher than those of the control group, and the differences were significant (χn 2=4.629, 4.786, 4.058, n P=0.031, 0.029, 0.044). The teeth bite force of the observation group at 3, 6 and 12 months after treatment were higher than those of the control group, and the differences were statistically significant (n t=8.265, 4.585, 3.722, n all P=0.001). The scores of masticatory function and speech function in the observation group at 12 months after treatment were lower than those in the control group, and the differences were significant (n t=3.701, 2.625, n P=0.001, 0.011).n Conclusions:The orthodontic treatment combined with dental implant for patients with congenital tooth loss has a good curative effect, which can improve the short-term success rate of implant, improve the bite force, and promote the recovery of mastication and speech function.
