As digital dental technologies gain traction, an increasing number of dentists are using intraoral scanning technique instead of traditional tray impressions. Intraoral scanner is undoubtedly a great invention in the dental industry. Selecting one intraoral scanner that meets your needs is quite important. In this article we will discuss some factors that are vital for consideration, and evaluate several scanners from different brands.

What should be considered?

Speed

Scanning speed is a key feature of intraoral scanners. One of the biggest benefits of this technology is the ability to create digital impressions in just minutes. So, an Intraoral scanner must be Fast at the speed of capturing an image. The faster you can scan, the more efficient you are during the day.

Accuracy

In order for the lab to deliver accurate results to you, your scan must be of the highest quality. The ideal scanner captures micro details to ensure the best quality. It should have the accuracy to support all types of restorative work, like crowns, bridges, dentures, partial dentures, etc. Accurate scanning means fewer retakes, happier customers, and more streamlined work.

Flow

Scanning flow means how smooth the scanning experience is. Does the scanner lose its place often? How smart is the artificial intelligence in the scanner? Does the scanner handle the corners or the mouth and the anterior region well without stopping when moving from one quadrant to the other? Does the scanner pick up where it left quickly if the scan is interrupted? These are the questions we should ask when evaluating the scanning flow of an intraoral scanner.

Easy to use

The daily work of a dental clinic is busy. Sometimes a dentist is responsible for diagnosing multiple patients. For higher work efficiency. Dentists need a good helper. The ease of use of an intraoral scanner is important to them. No matter how many interface functions, or whether the scanning process is smooth. Both are features of a scanner that are hard to ignore.

Service

Training and support can be considered as one of the standards to evaluate the service quality of scanner suppliers. When adapting to a new scanner, training helps users to get familiar with the full capabilities, while support helps users quickly solve the issues they face.

It is a more cost-effective option compared with Aoralscan3. But it requires 3-5 minutes of post-processing time, which is not good at saving working time for dentists. And its FPS is only 15.

Launca Medical, a Chinese-based company, launched the DL-206 scanner in 2020. DL-206 has made the scanner smaller than ever to provide a more comfortable access to patient’s mouth. The scanner itself is relatively quick. However, because it is difficult to use and has a tricky scan strategy, it is hard to achieve scan times of less than 60 seconds for full arch. Among all the factors, the main issue that slows this scanner down, especially for beginners, is the scanning strategy. Because of the fact that if the scanner loses its place, it does not return to the last point very quickly. Without a lot of practice, it’s hard to maintain a continuous scan across the arch.
