The purpose of this article is to describe a fabrication technique to assist dental technicians creating esthetic indirect composite restorations. After the teeth have been prepared and the models completed, the technician can begin the fabrication process. Translucent dentin is selected to reduce opacity and enhance the blend with the remaining dentition. High chroma modifiers can then be placed into the fossa area to replicate dentin seen in natural dentition. Different incisal materials can then be layered into the build-up to regulate the value of the restoration. Special effects such as hypocalcification are placed internally to mimic naturally occurring esthetics. Realistic anatomy is created using a small-tipped instrument directly into the final layer of uncured enamel material. Fissure characterization is placed in the restoration to match existing dentition. Fit and margins are verified on separate dies to minimize discrepancies. Path of insertion and proximal contacts are established on a solid model to minimize chairside adjustments.
本文的目的是描述一种制作技术,以协助牙科技术人员制作美观的间接复合树脂修复体。在牙齿预备完成且模型制作好后,技术人员即可开始制作过程。选择半透明牙本质以降低不透明度,并增强与剩余牙列的融合。然后可将高色度调节剂置于窝沟区域,以复制天然牙列中所见的牙本质。接着可将不同的切端材料分层堆积,以调整修复体的明度。内部添加诸如钙化不全等特殊效果,以模拟自然的美观效果。使用小尖头器械直接在未固化的釉质材料的最后一层中塑造逼真的解剖结构。在修复体中设置裂隙特征以匹配现有的牙列。在单独的代型上检查适合性和边缘,以尽量减少差异。在实体模型上确定就位道和邻面接触,以尽量减少椅旁调整。
