The rejuvenation of this dentition is initiated with the placement of six anterior crowns. Re-establishing the vertical dimension has allowed the restoration of pleasing proportions to the centrals. This has led to the re-assertion of the dominance of the centrals and thus corrected the reverse smile line. The restoration of these teeth demands harmonious accommodation of the requirements of esthetics, phonetics and function. These considerations are inseparable and are in fact, determinants of each other. Esthetics and phonetics help determine the degree of vertical opening and incisal edge placement. This location influences anterior guidance, lingual and labial contours, the pitch of the anterior teeth and proper lip support. The principles of proportion, so important in esthetics, allow us, to calculate incisor length. Thus, function, phonetics and esthetics are intimately intertwined and enhance one another in the restoration of vertical dimension of occlusion.
这一口牙列的年轻化始于六颗前牙冠的安置。重建垂直距离使中切牙恢复了令人满意的比例。这重新确立了中切牙的主导地位，从而纠正了反向微笑线。这些牙齿的修复需要在美学、语音学和功能需求之间实现和谐协调。这些考量相互不可分割，实际上彼此相互决定。美学和语音学有助于确定垂直开口程度和切缘位置。该位置会影响前导、舌侧和唇侧外形、前牙的倾斜度以及唇部的适当支撑。比例原则在美学中非常重要，它使我们能够计算切牙长度。因此，功能、语音学和美学紧密交织，在咬合垂直距离的修复中相互促进。
