Dental erosion is a frequently underestimated pathology that nowadays affects an increasing number of younger individuals. Often the advanced tooth destruction is the result of not only a difficult initial diagnosis (e.g. multifactorial etiology of tooth wear), but also a lack of timely intervention. A clinical trial testing a fully adhesive approach for patients affected by severe dental erosion is underway at the School of Dental Medicine of the University of Geneva. All the patients are systematically and exclusively treated with adhesive techniques, using onlays in the posterior region and a combination of facially bonded porcelain restorations and indirect palatal resin composite restorations in the anterior maxillary region. To achieve maximum preservation of tooth structure and predict the most esthetic and functional outcome, an innovative concept has been developed: the three-step technique. Three laboratory steps are alternated with three clinical steps, allowing the clinician and the dental technician to constantly interact during the planning and execution of a full-mouth adhesive rehabilitation. In this article, the third and last step of the three-step technique has been described in detail.
牙侵蚀是一种常常被低估的病理状况，如今影响着越来越多的年轻人。通常，严重的牙齿破坏不仅是由于初始诊断困难（例如牙齿磨损的多因素病因），还因为缺乏及时干预。日内瓦大学牙医学院正在进行一项针对重度牙侵蚀患者的全粘结方法的临床试验。所有患者均系统且专门采用粘结技术进行治疗，在后牙区域使用嵌体，在前上颌区域采用面部粘结烤瓷修复体与间接腭侧树脂复合修复体相结合的方式。为了最大程度地保留牙齿结构并预测最美观和功能最佳的效果，已开发出一种创新理念：三步技术。三个实验室步骤与三个临床步骤交替进行，使临床医生和牙科技师在全口粘结修复的规划和实施过程中能够持续互动。在本文中，已详细描述了三步技术的第三步也是最后一步。
