It has been suggested that inter-canine width plus 57% of the cumulative distance between the lateral aspect of the canines and the pupil centers can be used to estimate mouth width. Evidence also suggests that the distance between the medial irises approximates actual mouth width fairly well. However, these soft tissue prediction guidelines are limited because they rely on accurate medio-lateral positioning of the pupils within the orbits, for which no systematic empirical evidence appears to exist at this stage. It would, therefore, be more appropriate to use only known hard tissue landmarks in mouth width prediction. This study reports the results of using inter-canine width as a percentage of mouth width for its prediction. This method seems favorable in comparison to the other guidelines because it is as accurate, uses known hard tissue landmarks, and does not rely on assumptions concerning pupil location. Estimating mouth width by using the canines alone, therefore, seems the best guideline to use in facial approximation techniques, at least given knowledge existing at this stage.
有人提出，犬齿间宽度加上犬齿外侧与瞳孔中心之间累积距离的57%可用于估计口宽。证据还表明，内侧虹膜之间的距离与实际口宽相当接近。然而，这些软组织预测指南存在局限性，因为它们依赖于瞳孔在眼眶内精确的中外侧定位，而目前似乎尚无系统的实证证据支持这一点。因此，在口宽预测中仅使用已知的硬组织标志更为合适。本研究报告了使用犬齿间宽度占口宽的百分比进行预测的结果。与其他指南相比，这种方法似乎更具优势，因为它同样准确，使用已知的硬组织标志，且不依赖于关于瞳孔位置的假设。因此，至少根据目前已有的知识，仅使用犬齿来估计口宽似乎是面部复原技术中最佳的指导方法。
