This clinical report introduces an approach for detecting the supragingival finish line by penetrating the teeth and gingival tissue using optical coherence tomography (OCT) technology. This approach was used in 3 patients who underwent tooth preparation with a subgingival finish line. Consequently, the subgingival finish line, typically challenging to discern clearly in intraoral scans, was identifiable in the OCT image.
本临床报告介绍了一种利用光学相干断层扫描（OCT）技术穿透牙齿和牙龈组织来检测龈上边缘的方法。该方法应用于3例进行了龈下边缘牙体预备的患者。结果，在OCT图像中可识别出龈下边缘，而在口腔内扫描中通常难以清晰辨别该边缘。
