The digitization of the dental field has been vigorously promoted in recent years. An impression using an intraoral scanner is considered to significantly change future dental treatment. The purpose of this review is to evaluate accuracy and practicality of various intraoral scanners and verification method of intraoral scanners.
This review was based on articles searched through the MEDLINE and PubMed databases. The main keywords that were employed during the search were "Oral Scanner, Intraoral Scanners, Desktop Scanner, and Digital Impression".
It was reported that illuminance and color temperature affected trueness and precision of intraoral scanners. The repeatability of intraoral scanners indicated the possibility of producing fixed prostheses within the range of being partially edentulous. It is considered difficult to use intraoral scanners in fabricating cross-arch fixed prostheses. However, with intraoral scanners, it may be considered possible to fabricate mouth guards and dentures equivalent to those of desktop scanners. Current intraoral scanner scans are considered more comfortable than traditional impressions that use irreversible hydrocolloid and elastomeric impression materials.
Since the intraoral scanner is an evolving device, further improvement in accuracy is expected in the future. In addition, verification of the accuracy of intraoral scanners must be conducted accordingly.
近年来，口腔领域的数字化得到了大力推动。使用口腔内扫描仪进行印模被认为将显著改变未来的牙科治疗方式。本综述的目的是评估各种口腔内扫描仪的准确性和实用性，以及口腔内扫描仪的验证方法。
本综述基于通过 MEDLINE 和 PubMed 数据库搜索的文章。搜索中使用的主要关键词是“口腔扫描仪、口腔内扫描仪、台式扫描仪和数字印模”。
据报道，照度和色温会影响口腔内扫描仪的准确性和精密度。口腔内扫描仪的可重复性表明在部分缺牙范围内制作固定义齿的可能性。使用口腔内扫描仪制作跨颌固定义齿被认为具有一定难度。然而，使用口腔内扫描仪可能可以制作出与台式扫描仪相当的口腔护板和义齿。目前的口腔内扫描仪扫描被认为比使用不可逆水胶体和弹性印模材料的传统印模更舒适。
由于口腔内扫描仪是一种不断发展的设备，预计未来其准确性将进一步提高。此外，必须相应地对口腔内扫描仪的准确性进行验证。
