| 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(Class Ⅱ＜76,Class Ⅰ 76-86,Class Ⅲ＞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,Class Ⅱ groups(56.36±4.01,67.97±4.61)and Class Ⅲ groups(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 Class Ⅱ groups and Class Ⅲ groups (P＞0.05).The width of the base bone in the premolar region was significantly different(P＜0.05)between Class Ⅲ groups and Class Ⅰ groups,and Class Ⅲ groups 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 Class Ⅱ groups 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 Class Ⅱ groups and Class Ⅲ groups.Clinicians should comprehensively analyze the causes of malocclusion and seize the opportunity to coordinate and match the bone width in the early time. |
