Ceramic laminate veneer restorations are indicated in several clinical situations. Indirect restorations are usually chosen if the less-invasive options - bleaching, resin infiltration, or composite resin restorations - are not possible, or when it is too difficult to achieve an esthetically pleasing result in the long term. Bonded indirect partial restorations are highly dependent on their adhesive interface, as these thin restorations have a relatively low cohesive strength. Therefore, preservation of sound enamel, conditioning of the restorations and of the substrate, and luting procedures are of paramount importance for a successful outcome. Even when utmost care is taken during every step of the procedure, failures such as fractures, chipping, or marginal discoloration and defects sometimes occur. Only very few of these cases of failure are presented or are a subject of interest. In this case presentation, a fracture repair is performed using an infiltration technique with a resin composite material.
陶瓷贴面修复适用于多种临床情况。如果无法采用侵入性较小的方法——漂白、树脂渗透或复合树脂修复,或者长期难以获得美观的效果时,通常会选择间接修复。粘结间接局部修复在很大程度上依赖于其粘结界面,因为这些薄修复体的内聚强度相对较低。因此,保存完好的牙釉质、对修复体和基牙进行预处理以及粘结操作对于取得成功的结果至关重要。即使在操作的每一步都极其小心,有时仍会出现诸如断裂、崩瓷、边缘变色和缺损等失败情况。这些失败案例中只有极少数被呈现或受到关注。在本病例报告中,使用树脂复合材料的渗透技术进行了骨折修复。
