Abstract: In tooth defect restoration , the technology of obtaining digital impression through intraoral scanning is used more and more frequently in clinical practice because of its simple, comfortable and fast characteristics. The accuracy of digital impression (including trueness and precision) is the key to final success of restoration. The scanning accuracy is different because of different scanning principles of various intraoral scanning equipment. In addition, the scanning scheme adopted in clinical operation, preparation quality and oral environment will all affect scanning accuracy. Understanding the principle of intraoral scanning and relevant influencing factors of scanning accuracy, and taking corresponding coping strategies in clinical operation can improve scanning accuracy, and then eventually improve the success rate of digital restoration of tooth defects.

Key words: intraoral scanning, accuracy, trueness, precision
