摘要
视错觉指人眼观察的景象与客观呈现的景象不完全一致的现象。本文从视错觉原理出发,结合临床应用,从修复体颜色、形状以及颜面部美学设计等角度阐述口腔临床工作中的视错觉现象。颜色的同色异谱现象、颜色的恒常性以及谢弗勒尔错觉提示修复体颜色的个性化表达及以及周围环境对颜色的影响,技师制作修复体时的背景光线应与比色背景光线一致;波根多夫错觉与斜塔错觉提示人眼在口腔内观察的局限性,口腔内扫描技术可代替人眼观察、检查牙体预备的质量;面部扫描、头影测量等检查手段也可减少人眼观察时参考物对结果的主观影响;艾宾浩斯错觉则提示整体与局部的相互影响。在口腔诊治时术者应注重修复体与颜面部的协调,同时考虑患者的性别、年龄等个性化特征,力求和谐的美学呈现。未来的研究需要关注视错觉现象在口腔诊疗中的具体影响,加强医生⁃技师⁃患者三者间沟通,医师务必认识视错觉降低主观偏差对临床规范化操作的影响;合理利用视错觉,让患者呈现个性化的牙齿和颜面部的和谐美。
Optical illusion refers to the phenomenon in which the scene observed by the human eye is not complete⁃ly consistent with the objectively presented scene.Optical illusions in stomatology,as well as their clinical application,are demonstrated in this paper in terms of shade,shape and aesthetic design.Shade is not only affected by the optical il⁃lusions with which it is associated,such as color metamerism,color constancy and the Chevreul illusion,but also influ⁃enced by the surroundings.It is suggested that the surrounding lighting during veneering should be the same as that dur⁃ing color matching in the clinic.As indicated by the Poggendorf illusion and the Leaning Tower illusion,the practice should be conducted and checked from multiple perspectives to compensate for the limitation of human eyes,such as in⁃traoral scanning.Other digital technologies,including digital facial scanning and cephalometric measurement,could be used to reduce the subjective influence of observation.In terms of esthetic design,the interaction of the part and the whole,suggested by Ebbinghaus illusion,should be considered:an individual harmony smile should be designed consid⁃ering the characteristics of the personality and the features of the face,lips,teeth and gingiva of the patient.Further⁃more,personal information,such as gender and age,should be taken into consideration in beautification presentation.Further research should be focused on the influence of optical illusions in stomatology in more details.More communica⁃tion among doctors,technicians and patients is needed.Clinicians should be aware of the impact of optical illusions to reduce subjective bias in clinical standardized operations and further take advantage of optical illusions to create beauti⁃fication presentations of dental restorations and smiles.
