摘要:
[摘要]目的：明确混合牙列期儿童CBCT测量咬合参数与金标准石膏模型上获得的结果是否具有一致性或更具有优越性。方
法：将CBCT扫描获得的数据导入MIMICS软件获得三维重建图像,同时制取超硬石膏模型。由测量人员分别进行前牙覆牙合、覆
盖及第一恒磨牙咬合关系的重复测量，对比分析测量结果。结果：两种方法测量前牙覆牙合关系，测量结果符合率为81.25%，
不符合率为18.75%，一致性强度为高度一致（K 值=0.76）；两种方法测量前牙覆盖关系，测量结果符合率为82.03%，不符合
率为17.97%，一致性强度为高度一致（K 值=0.75）；两种方法测量第一恒磨牙咬合关系，左侧测量结果符合率为89.06%，不
符合率为10.94%，一致性强度为最强（K值=0.81）；右侧测量结果符合率为90.63%，不符合率为9.37%，一致性强度为最强
（K 值=0.81)。结论：CBCT和石膏模型在测量混合牙列期儿童咬合参数具有较高的一致性，CBCT在儿童咬合诱导中具有一定
的临床应用价值。

Abstract:
Abstract:Objective To clarify whether the results of CBCT analysis of occlusal parameters in mixed dentition children are
consistent or superior to those obtained in gold standard plaster model. Methods The data obtained by CBCT scanning were
imported into MIMICS software to obtain three-dimensional reconstruction image, and at the same time the plaster model was
made.Repeated measurements of anterior overbite (occlusion), overburden and occlusal relationship of six-year-old teeth were
carried out by the surveyors, and the results were compared and analyzed. Results Two methods were used to measure the
relationship between anterior overbite and occlusion. The coincidence rate was 81.25% , the non-coincidence rate was 18.75% and
the consistency intensity was highly consistent (K value 0.76).Two methods were used to measure the relationship between anterior
overburden and occlusion. The coincidence rate was 82.03% , the non-coincidence rate was 17.97% , and the consistency intensity
was the same (K value 0.75) .Two methods were used to measure the occlusal relationship of six-year-old teeth. The results on the left
side were the coincidence rate was 89.06%,the non-coincidence rate was 10.94%, the consistency intensity was the strongest (K value
0.81).The results on the right side were the coincidence rate was 90.63% , the non-coincidence rate was 9.37% ,and the consistency
intensity was the strongest (K value was 0.81). Conclusion CBCT and plaster model have high consistency in the analysis of
occlusal relationship in mixed dentition children. CBCT has certain clinical value.
