Full-coverage bonded porcelain restorations offer predictable treatment options in dentistry, but a certain amount of tooth material must be removed to allow space for the required thickness of the restorative material. Laminate veneers and inlays are considered minimally invasive, but they also require removal of sound enamel. Sometimes, it may be preferable to extend the veneer preparations beyond the contact points toward the palatal surface, to hide the margins of the restoration, which necessitates removal of additional tissue. Improvements in adhesive technologies mean that small indirect restorations may be applied with removal of only a superficial layer of enamel. This clinical report describes a situation in which application of porcelain laminates and sectional veneers was chosen as the therapy of choice. A step-by-step protocol is proposed for cementation of these delicate restorations, and finishing procedures are described.
全瓷贴面修复在牙科领域提供了可预测的治疗选择，但必须去除一定量的牙齿材料，以便为修复材料所需的厚度留出空间。瓷贴面和嵌体被认为是微创的，但它们也需要去除健康的牙釉质。有时，将贴面预备延伸至接触点以外直至腭面以隐藏修复体边缘可能更可取，这就需要去除额外的组织。粘接技术的改进意味着小型间接修复体仅需去除表层牙釉质即可应用。本临床报告描述了选择应用瓷贴面和分段贴面作为治疗方案的情况。提出了这些精细修复体粘接的分步方案，并描述了修整步骤。
