Abstract
The first step in making the prosthesis that satisfies the patient and the clinician is the accurate impression preparation. Conventional impression methods have been used for a long period of time, but digitization, which has recently been applied to various fields, has brought about many changes in the field of dentistry. In dentistry, restoration of implants is the fastest digital change, and many studies and attempts have been made on 'digital work flow' which is connected to the digital system from the surgery plan to the prosthesis restoration. Digital implant impression imaging begins with the process of connecting the scan body and the implant fixture and forming the surrounding teeth in 3D, where the intraoral scanner acts like the conventional impression coping. Opposite dentition and occlusal relationships can also be achieved using an intraoral scanner. During this process, you should familiarize yourself with the features and usage of the various types of intraoral scanners and make an appropriate impression. Advantages of the digital impression method include the prevention of cross infection, reduction of the risk of impression and model damage, ease of data retention and permanence, and ease of modification of impression information. Increase in initial costs for purchasing, time and effort to adapt and master the new method. Although the digital impression is popularized, many additional studies are needed due to the lack of cumulative research. The research on the accuracy that is most important when making the impression is mostly in vitro studies performed under a certain condition, but it is reported that the accuracy of the impression method is not lower than that of the conventional impression method. Makes it possible to expect a faster, more accurate and convenient digital impression in the future.
