With the rise of the digital dentistry trend, more and more dental practices prefer to picking intraoral scanners as their oral treatment tools. The market of intraoral scanner is potential. What features to look for in an intraoral scanner becomes a matter of urgency for dentists. In general, dentists may be more concerned about the patient experience. Therefore, the size and dimensions of the intraoral scanner become particularly important.
Whether the product is cost effective is also an issue for dentists to consider. However, they tend to think that the higher the price and visibility of a product, the better its quality. So is this true? Actually, not necessarily.
Consumers usually judge whether a product is good or not by the accuracy and speed of the scanner. When it comes to speed, it has to be said that this is one of the most important factors for dentists. Because a faster intraoral scanner speed means more time saved for the dentist.
What factors determine the intraoral scanner speed? To answer this question, we must first understand how intraoral scanners work.
Working Principle of Intraoral Scanner
These pictures are extracted as point clouds. After the point cloud of each frame is extracted, an algorithm stitches the point cloud together to form the final scan data.
Frame Rate of the Scanner?
The scanner’s built-in camera captures pictures of the teeth in the mouth. For example, INO100 can capture several hundred pictures per second or more. And the frame rate of the mouth scan refers to the number of pictures extracted from the captured picture point cloud in one second according to the algorithm.
Factors Affect the Speed of Intraoral Scanner
Frames Per Second
A certain number of frames are needed for successful point cloud acquisition, if more frames in one second (large frame rate) means that the physical point cloud acquisition can be completed faster and the scanning speed will be faster.
However. The more images there are, the more time it takes to extract the point cloud, so increasing the frame rate does not directly increase the speed. The frame rate is not the decisive factor for scanning speed.
Image area
The image format directly determines the number of extracted point clouds. Therefore, the larger the aspect, the more point clouds are extracted, and the faster the point clouds are collected to complete the object feature requirements. The scanning speed is also faster.
Algorithm
For any high-tech product, its algorithm is very important. For intraoral scanners, the algorithm has a direct impact on the smoothness of point cloud stitching and fusion. The better the algorithm, the faster the model stitching and fusion. This means the faster the scanning speed of the intraoral scanner.
