Abstract

A digital technique for designing and fabricating an individual tooth tray used for taking subgingival impression of complete crown preparation was described. The digital model of required dentition region was obtained before performing crown preparation. An individual tooth tray with retention attachments was designed and printed with plastic material. After conducting crown preparation, the individual tooth tray loaded with the final impression material was placed onto the abutment to deliver the impression material subgingivally. A final overall impression was made with full arch stock tray to pick up the individual tooth tray with the accurate impression of abutment.

摘要

描述了一种用于设计和制作用于全冠预备龈下印模的个性化牙托的数字技术。在进行牙冠预备之前，获取所需牙列区域的数字模型。设计带有固位附件的个性化牙托，并用塑料材料打印出来。在进行牙冠预备后，将装有最终印模材料的个性化牙托放置在基牙上，龈下输送印模材料。用全牙弓托盘制作最终的整体印模，以获取带有基牙精确印模的个性化牙托。
