摘　　要：目的探讨恒牙早期不同矢状骨面型患者与上颌骨宽度之间的关系。方法选取2019年1月至2022年1月于中国科学技术大学附属第一医院(安徽省立医院)符合纳入标准的恒牙早期错(牙合)畸形患者88例,其中男性50例,女性38例;摄片时年龄(12.58±1.60)岁;按照上下颌骨前后不调指数进行骨面型分组(骨性Ⅱ类组<76;骨性Ⅰ类组76~86;骨性Ⅲ类组>86),利用锥形束CT测量各组患者前磨牙区、磨牙区的上颌基骨及牙槽骨宽度,并进行对比分析。结果进行上颌第一磨牙区牙槽骨宽度和上颌第一磨牙区基骨宽度3组间比较,骨性Ⅱ类(56.36±4.01、67.97±4.61)及骨性Ⅲ类组(57.51±3.10、68.80±3.37)相对骨性Ⅰ类组(59.01±3.41、71.07±4.65)均较小,差异均有统计学意义(P<0.05),但是骨性Ⅲ类组与骨性Ⅱ类组之间差异无统计学意义(P>0.05)。与骨性Ⅰ类组比较,骨性Ⅲ类组患者上颌第一前磨牙基骨宽度及第二前磨牙基骨宽度较窄(45.70±3.13比49.07±3.78、56.03±5.32比62.19±5.75),差异有统计学意义(P<0.05),但前磨牙区牙槽骨宽度之间差异无统计学意义;骨性Ⅱ类组患者上颌第一前磨牙区基骨宽度及牙槽骨宽度均相对骨性Ⅰ类组较窄(45.70±3.37比47.44±3.41、46.95±3.83比49.07±3.78),差异有统计学意义(P<0.05)。结论骨性Ⅱ类及骨性Ⅲ类患者均存在上颌宽度发育不足,临床医生应综合分析骨性错(牙合)畸形引起的原因,进行早期宽度不足的协调与匹配。Objective To evaluate the maxillary basal width and alveolar bone width of early permanent dentition patients with different sagittal skeletal patterns.Methods A total of 88 early permanent dentition patients were selected,included 50 males and 38 females,with an average age of 12.58±1.60 years when taken CBCT.According to APDI value,patients were grouped into different sagittal skeletal patterns(ClassⅡ<76,ClassⅠ76-86,ClassⅢ>86)and measured the maxillary basal width and alveolar bone width using CBCT.Results When compared the alveolar bone width and maxillary basal width in the first molar area,ClassⅡgroups(56.36±4.01,67.97±4.61)and ClassⅢgroups(57.51±3.10,68.80±3.37)were smaller than those in Class I groups(59.01±3.41,71.07±4.65),and the difference is statistically significant(P<0.05).However,there was no statistically significant difference between ClassⅡgroups and ClassⅢgroups(P>0.05).The width of the base bone in the premolar region was significantly different(P<0.05)between ClassⅢgroups and ClassⅠgroups,and ClassⅢgroups were narrower(45.70±3.13 vs.49.07±3.78,56.03±5.32 vs.62.19±5.75),the differences of alveolar bone width were not statistically significant.The alveolar bone width and basal bone width of the maxillary first premolars in ClassⅡgroups were narrower than those in Class I groups(45.70±3.37 vs.47.44±3.41,46.95±3.83 vs.49.07±3.78),the differences were statistically significant(P<0.05).Conclusions The maxillary width was insufficient in both ClassⅡgroups and ClassⅢgroups.Clinicians should comprehensively analyze the causes of malocclusion and seize the opportunity to coordinate and match the bone width in the early time.
