摘要:

获得足够的釉质粘接是保证瓷贴面固位、边缘封闭及临床使用效果的共识性建议,牙体预备后,基牙的粘接面就确定下来。由于唇面釉质厚薄不均,常常存在或多或少的牙本质暴露,而分区识别粘接面上的釉质或牙本质(简称釉本)并采用“选择性酸蚀”使其获得最大粘接力的处理方式,将有助于提高瓷贴面的整体粘接强度。不同于以往“选择性酸蚀”裸眼识别釉本分区的不确定性和经验依赖,本技术方案通过第一个目标修复体空间定深导板控制预备深度,获得准确的釉本分区;并将其映射到第二个分区粘接导板里,依靠第二个导板分别对粘接面上的釉本进行不同处理,实现了精准的、可预期的瓷贴面的分区粘接,获得了更好的粘接效果。

Abstract:

Obtaining optimal enamel bonding is a common recommendation to ensure the retention, edge closure, and clinical service life of porcelain veneers. Bonding surface is determined after tooth preparation. More or less dentin exposure often occurs due to the uneven thickness of the enamel. Identifying the enamel or dentin on the bonding surface and adopting the “selective etching” technique are useful to obtain the maximal bonding strength. Naked eye recognition in “selective etching” has uncertain results and is experience-based, whereas the proposed technique controls the preparation depth through the first target restoration space template to obtain the accurate enamel and dentin subarea. It is mapped to the second bonding template, depending on the treatment carried out on the enamel and dentin surface, to accurately predict the adhesion of porcelain veneers.

Key words: porcelain veneer, selective etching, sequence 3D printing template, partition bonding, target restoration space
