The chin represents one of the most important determinants of the facial aesthetics. Like many aesthetic parameters, the "ideal" chin has changed in history regarding projection and prominence. From the retrusive profiles of the Renaissance, stronger and more defined mandibular contour are nowadays desired both by masculine and feminine population.This change in the ideal references plays an important role in diagnosis and treatment planning. Various techniques for chin augmentation have been described, using both alloplastic materials and osteotomies.An interesting osteotomy variant, so-called chin shield osteotomy, has been described by Triaca et al to avoid a deep mentolabial fold. The authors describe herein the use of a shield plate, very similar in his form to Captain America's shield, that can at the same time provide bone fixation and soft tissues sustain in the mentolabial fold region, preventing the invasion of the gap between the bone fragments by the connective tissue, as it happens in a guided bone regeneration procedure.
颏部是面部美学的重要决定因素之一。与许多美学参数一样，“理想”的颏部在突出度和长度方面在历史上已经发生了变化。从文艺复兴时期的后缩型，到现在男性和女性都更喜欢更强烈、更明确的下颌轮廓。这种理想参考的变化在诊断和治疗计划中起着重要作用。已经描述了各种颏部填充技术，包括使用假体材料和截骨术。Triaca 等人描述了一种有趣的截骨术变体，即所谓的颏盾截骨术，以避免形成深的颏唇沟。作者在此描述了一种盾牌板的使用，其形状非常类似于美国队长的盾牌，它可以同时提供骨固定和颏唇沟区域的软组织支撑，防止结缔组织侵入骨碎片之间的间隙，就像在引导骨再生过程中一样。
