简介：光学相干断层扫描（OCT）作为一种非侵入性和高精度的定量信息提供工具，在过去的十年中已经得到了很好的研究。边缘差异值可以在三维（3D）微毫米尺度下进行的光学活检中仔细检查，并揭示软组织和硬组织的详细定性和定量信息。基于OCT的高分辨率3D图像可以对发现复发性龋齿、修复失败、分析牙冠制备的精度以及修复元件与牙龈和牙齿硬组织的边缘适配误差提供显著影响。在口腔修复的CAD/CAM过程中，避免任何误差对于医生和技术人员来说都是重要的，以减少时间和材料的浪费。此外，OCT图像有助于实现新的或半熟练的从业人员分析他们的牙冠准备工作，并帮助他们比传统方式更快地发展技能。本研究的目的是突出的优势，OCT在高精度的prosthetic preparations.MATERIALS和METHODS：25前牙和侧牙的准备工作进行了7个不同的患者。使用传统的光电系统（Apolo Di，Syrona）和使用OCT的光谱域（Dental prototype，在860 nm下工作）获得假体区域的印象。对于传统的印模技术，制备边缘是由牙龈浸渍线预先抬高的。OCT印模技术没有进行特殊的治疗。结果：传统的光电系统进行扫描证明是快速和准确的印模技术。结果由扫描程序完成后获得的3D虚拟模型表示。为了获得良好的光学印模，将排龈线插入准备好的牙齿和牙龈组织之间，以更好地提升牙齿颈缘准备。实施光谱OCT是为了观察质量以及该技术的优势。结论：考虑到这些方面，光学相干断层扫描可以作为一个有价值的工具，牙科印模技术，是非侵入性的，但也对边缘牙龈组织的非破坏性，与传统的光电技术相比，排龈线仍然是强制性的。
INTRODUCTION: The use of Optical Coherence Tomography (OCT) as a non-invasive and high precision quantitative information providing tool has been well established by researches within the last decade. The marginal discrepancy values can be scrutinized in optical biopsy made in three dimensional (3D) micro millimetre scale and reveal detailed qualitative and quantitative information of soft and hard tissues. OCT-based high resolution 3D images can provide a significant impact on finding recurrent caries, restorative failure, analysing the precision of crown preparation, and prosthetic elements marginal adaptation error with the gingiva and dental hard tissues. During the CAD/CAM process of prosthodontic restorations, the circumvent of any error is important for the practitioner and the technician to reduce waste of time and material. Additionally, OCT images help to achieve a new or semi-skilled practitioner to analyse their crown preparation works and help to develop their skills faster than in a conventional way. The aim of this study is to highlight the advantages of OCT in high precision prosthodontic restorations.MATERIALS AND METHODS: 25 preparations of frontal and lateral teeth were performed for 7 different patients. The impressions of the prosthetic fields were obtained both using a conventional optoelectronic system (Apolo Di, Syrona) and a Spectral Domain using OCT (Dental prototype, working at 860 nm). For the conventional impression technique the preparation margins were been prelevated by gingival impregnated cords. No specific treatments were performed by the OCT impression technique.RESULTS: The scanning performed by conventional optoelectronic system proved to be quick and accurate in terms of impression technology. The results were represented by 3D virtual models obtained after the scanning procedure was completed. In order to obtain a good optical impression a gingival retraction cord was inserted between the prepared tooth and the gingival tissue for a better elevation of the tooth cervical margin preparation. Spectral OCT was enforced in order to observe the quality but also the advantages coming from this technology. No special preparation was performed for this operation.CONCLUSION: Considering these aspects, OCT could be used as a valuable tool for dental impression technology, being non-invasive but also non-destructive on the marginal gingival tissue, in comparison with conventional optoelectronic technology where the gingival retraction cord is still mandatory.
