摘　　要：目的探讨特发性髁突吸收(idiopathic condylar resorption,ICR)与牙弓宽度不调的相关性。方法按同一纳入标准收集32例ICR患者(试验组)及20例无髁突吸收患者(对照组)。试验组按髁突吸收累及侧分为单侧ICR组和双侧ICR组;按髁突吸收程度分为ICRⅠ、ICRⅡ、ICRⅢ亚组。无髁突吸收患者作为对照组,测量各组患者锥形束CT片上的牙弓前、中、后段宽度,并对测量值进行统计学分析。结果单、双侧ICR组患者上颌前、中、后段宽度与对照组比较均减小,差异有统计学意义(P<0.01)。而下颌宽度与对照组比较差异无统计学意义(P>0.05)。各亚组间牙弓前、中、后宽度比较差异亦无统计学意义(P>0.05)。结论ICR患者几乎都存在上下颌牙弓宽度不调,但宽度不调与髁突吸收的严重程度无明显相关性。Objective To investigate the relationship between idiopathic condylar resorption(ICR)and arch width disorder.Methods Thirty-two patients with ICR and twenty patients without condylar resorption were enrolled according to the same inclusion criteria.They were divided into experimental group and control group.The experimental group was divided into unilateral ICR group and bilateral ICR group according to the affected side of condylar resorption,and then experimental group was divided into subgroups ICRⅠ,ICRⅡand ICRⅢaccording to the degree of condylar resorption.Patients with no condylar resorption were used as a control group.The width of anterior,middle and posterior segments of dental arch on cone beam computed tomography(CBCT)was measured and the two groups of measured values were statistically analyzed.Results Compared with the control group,the width of maxillary anterior,middle and posterior segments in ICR group was significantly reduced,and the difference was statistically significant(P<0.01).But the width of mandibular segment was not significantly different from that in control group(P>0.05).There was no significant difference in the width of anterior,middle and posterior dental arch between subgroups(P>0.05).Conclusion Almost all patients with ICR have malocclusion of maxillary and mandibular arch width,but there is no significant correlation between the malocclusion width and the severity of condylar resorption.
