摘要
目的 探讨正常牙合成人牙弓容量与颅面结构的关系。方法 对 90名上海地区正常牙合成人牙牙合模型、X线头颅后前位片和侧位片进行线距测量分析。结果 下尖牙间宽度对上下牙弓的影响最大。上下牙弓容量不仅与颅面部宽度和深度有关 ,还与垂直向的生长密切相关。同时建立了上海地区成人X线头影测量Coben分析法的正常值范围。结论 颅、牙合、面的生长是三维的 ,在宽度、深度和高度上互相协调、制约和补偿。
Objective To examine the relationships between dental capacity and cranioficial structures.Methods Models, posterioanterior and lateral cephalometric films of 90 adults with normal occlusion in Shanghai area were measured and analyzed. Results The canine width of lower arch extended an important influence on the upper and lower arch. The dental capacity was highly correlated not only with the width and depth of cranioficial structure,but with the height as well. The database of Coben analysis for normal Shanghai adults occlusion was established.Conclusion The growth between dental and cranioficial structure was harmonized in three dimensions.
