This article describes a procedure to achieve natural-looking morphology and surface textures in anterior ceramic restorations. The natural dentition serves as an atlas to interpret and mimic the orientation and location of dental anatomic structures. Transition angles and ridges; proximal slopes; labial grooves; the cervical, middle, and incisal thirds of the buccal surface; the lingual central concavity; and the lingual transition ridges should all be mimicked by the prosthetic work to achieve esthetic integration. The position of buccal transition ridges directly influences the buccal mesiodistal dimension-the so-called "visual width." Once the desired morphology is obtained, a gold powder is used to outline its surface texture. This uniform golden appearance allows for precise identification of specific surface features such as ridges, grooves, and sulci for their consequent mimicking onto the ceramic surface. Specific surface texture characteristics reflect light and thus enhance visual dimensions of the rehabilitation and its final esthetic integration.
本文介绍了一种在前牙陶瓷修复体中实现自然形态和表面纹理的方法。天然牙列可作为一个图谱，用于解读和模仿牙齿解剖结构的方向和位置。修复工作应模仿过渡角和嵴、邻面斜坡、唇沟、颊面的颈三分之一、中三分之一和切三分之一、舌中央凹以及舌过渡嵴，以实现美学整合。颊过渡嵴的位置直接影响颊面近远中径，即所谓的“视觉宽度”。一旦获得所需的形态，就使用金粉勾勒其表面纹理。这种均匀的金色外观有助于精确识别特定的表面特征，如嵴、沟和裂，以便随后模仿到陶瓷表面上。特定的表面纹理特征会反射光线，从而增强修复体的视觉尺寸及其最终的美学整合效果。
