Mesiodistal tooth width discrepancies between the maxillary and mandibular teeth may be present in any dentition. A mismatch in width between the maxillary and mandibular teeth can have a pronounced effect on the occlusion by preventing the correct interdigitation of buccal teeth and the correct overbite/overjet relation of anterior teeth. No simple graphical method of analysis of tooth width discrepancy has previously been devised. The present graphical analysis of tooth width discrepancy has been developed to comprehensively assess new cases for tooth width discrepancy. The findings from the graphical analysis of tooth width discrepancy were invaluable as an aid in diagnosis and treatment planning. Diagnostic set-ups performed on each malocclusion supported the findings from the graphical analysis. The analysis provided the ability to visually recognise and localise the tooth or teeth causing the tooth width discrepancy. Computerisation of the graphical analysis of tooth width discrepancy will simplify and encourage its use in the overall diagnosis and treatment planning of all malocclusions.
任何牙列中都可能存在上颌牙与下颌牙之间的近远中牙宽度差异。上颌牙与下颌牙之间的宽度不匹配会对咬合产生显著影响，因为它会阻止颊侧牙齿正确的相互交错以及前牙正确的覆合/覆盖关系。以前尚未设计出简单的分析牙宽度差异的图形方法。目前的牙宽度差异图形分析方法已被开发出来，用于全面评估牙宽度差异的新病例。牙宽度差异图形分析的结果对于辅助诊断和治疗计划非常宝贵。对每种错牙合畸形进行的诊断性排牙支持了图形分析的结果。该分析能够直观地识别和定位导致牙宽度差异的一颗或多颗牙齿。牙宽度差异图形分析的计算机化将简化并促进其在所有错牙合畸形的整体诊断和治疗计划中的应用。
