摘　　要：目的:研究快速和慢速扩弓对唇腭裂患者上颌骨的三维影响。方法:采用Hass矫治器进行快速或慢速扩弓,每组患者各8例,平均年龄9.5岁。治疗前后分别进行锥形束CT(CBCT)分析,测量项目包括:上颌骨颊侧骨板的厚度、腭中缝宽度、基骨弓间距离、鼻腔宽度。结果:快速及慢速扩弓均可显著增加腭中部裂隙打开量及基骨弓间距离(P<0.05),鼻腔宽度增加,颊侧骨板厚度轻微减少且慢性扩弓减少量相对较少,但无统计学差异(P>0.05)。上述指标在快速扩弓组及慢性扩弓组之间无统计学差异(P>0.05)。结论:在唇腭裂患者中,快速和慢速扩弓均可增加上颌骨宽度,但慢性扩弓组可能更有利于颊侧骨组织改建。Objective:To investigate maxillary changes of rapid and slow maxillary expansion protocols through cone beam CT(CBCT)analysis.Methods:Sixteen patients(mean age 9.5 years)were randomly distributed into 2 groups:rapid maxillary expansion(n=8)and slow maxillary expansion(n=8)via Hass appliance.Maxillary changes were measured by CBCT analysis.The buccal bone plate thickness,palatal cleft width,nasal cavity width,and maxillary width were also recorded accordingly.Results:We found no statistical difference between the two groups in terms of palatal cleft width,nasal cavity width,and maxillary width(P>0.05).Buccal bone plate thickness reduction was smaller in slow maxillary expansion group than those in rapid maxillary expansion group,althrough there was no statistical difference(P>0.05).Conclusions:Rapid and slow maxillary expansion could expand the maxillary width,and the slow maxillary expansion might result in light and continuous force which might be more favorable to periodontal tissue.
