Impression Scan Mode and High-Resolution Scan Mode

This Function allows you to seamlessly overlay data acquired by scanning the patient’s teeth with data collected by scanning a traditional impression. This scanning process can be used for just a spot area or for the whole jaw.

There are considerable benefits of this function in certain situations. For example, your patient is bleeding too much, being able to combine the intraoral scan with the impression scan will allow you to get more accurate results.

There are cases where an area is too deep and narrow to scan, using the impression scan function will allow you to acquire the necessary data and this function is also useful in occlusion alignment, therefore it could save you time and money.

High Resolution Scan Function

This functions enables the scanner to capture a high-resolution images for the entire jaw or just a spot area, but it does not mean that you should starting scanning everything in high resolution because, this will slow down the post-processing and result in a bigger file size that is why we encourage you to just use this function if it is absolutely necessary.

Most of the time, that standard resolution is enough to get the data that you need for most cases. You can use the high-resolution function when you need to get a lot more data in a spot, especially when you are scanning a prepared teeth or certain scan bodies which require more details. You can enable and disable this function throughout the scanning process by double pressing the button on the scanner or clicking the icon on the desktop.

There’s no need to worry about discrepancies in the scan data when you scan in both high resolution and standard resolution as iScan will merge both data during post-processing for smooth results.
