In our previous post Intraoral Scan: How can it help in your dental clinic? we described how an intraoral scanner works, the types that exist and we also list 8 advantages of having it in your clinic. On this occasion, we want to share with you a very useful comparison between the main intraoral scanners currently on the market that will help you to choose when purchasing one. The comparison is based mainly on the contributions made by The Institute of Digital Dentistry (The Institute of Digital Dentistry) and the experience of Dr Hamid Al-Hassiny, Dr Haidar Al-Hassiny and Dr Ahmad Al-Hassiny.
Doctors Al-Hassiny attended the ISD 2019 fair held in Germany, and spent 5 days, more than 28 hours, testing the main intraoral scanners (IOS) that were on display. After these tests they have published an intraoral scanner comparison to help dentists choose the most suitable intraoral scanner. There are many options in the market and sometimes it can be complicated to choose an intraoral scanner because each representative, says that his scanner and his system, are the best.
Comparison criteria for the evaluation of intraoral scanners
In order for the comparison to be made in the same way, the tests of the intraoral scanners have been carried out using different types of teeth, with full arch scans and also bite scans. The test was carried out in this way because, due to rules in the exhibition, it was not possible for them to carry out the tests directly in the mouth.
In order to offer a graphical score, 5 stars were used, so the more stars an intraoral scanner has in one of the criteria, the better. Here is what the comparison criteria were and why:
- Scanning speed: One of the most important factors when choosing an intraoral scanner is the speed of the scan. Therefore, the first thing that doctors take into account for the development has been the speed of full arch scanning. Although the evaluation is relative, the five star rating gives an idea of which ones are faster or slower.
- Scanning flow: not only the speed of the scan is relevant, but also how smooth the experience is. Whether the intraoral scanner handles well in the corner and anterior region, or recovers quickly after losing the scan. Also if it joins the images well or if it loses frequency. The assessment of the scan flow, indicates which experience has been irregular or in any case, the lack of response.
- Intraoral scanner size: Not only the size of the intraoral scanner head was taken into account, but also the weight and overall size. Although, judging from the overall size, some scanners are heavier and more complicated than others. The focus has been on ergonomics, weight and overall, how comfortable the scanner feels in the hand and when scanning.
- Ease of use: this criteria takes into account both the hadware and the way the software was managed or if there were any problems with scanning, processing and general workflow.
- Intraoral scanner price: Another criteria that dentists consider quite important is the price, since this can vary, depending on the cost, complements, distributors or geographical location. No exact numbers are provided, but a relative comparison based on the most expensive and least expensive scanners.
- Subscription requirements and maintenance packages: The subscription requirement for the use of the intraoral scanner may be mandatory, recommended or not required. The assessment has been made on this basis, as some companies claim that they do not require any kind of subscription, but this is sometimes not entirely true. Many have some kind of annual subscription for support and maintenance and others even require a subscription to be able to use them.
- Open or closed scan export: all scanners are now open, which allows to export at least one of the following source files STL, OBJ and/or PLY, however, they did not take this criteria into account for the evaluation.
- Autoclave scanning tips: If the tips can be autoclaved and how many cycles can be completed before replacing them.
- Touch screen: the intraoral scanners connected to the trolleys are actually screen-touch. This does not apply to those connected to a laptop via a USB port as the screen will work as a touch screen, but not all the software was designed with touch interaction in mind and can be better handled with a mouse and keyboard.
- Wireless scanner: the assessment is based on whether or not wireless options are available for the scanner.
- Caries detection: this criterion is based on whether or not the intraoral scanner has a caries detection function such as transillumination or fluorescence.
- CAD Integration: you may wonder if the scanner has integrated CAD/CAM design functions. If not, you will have to export the files and the prostheses will have to be designed in third-party software such as Exocad.
Intraoral scanner comparison:
iTero Element 5D by Align Technology
- The iTero Element 5D scanner by Align Technology It does the job, although it is relatively large and heavy (500g). Because of this, some users with little practice may have difficulty finishing a full arch scan.
- The head protrudes from the body, this design option was not particularly helpful to the doctors and, in fact, made scanning some areas uncomfortable for them.
- It's not a very fast scan and the workflow is not the best.
- It has caries detection functionality and performs it through a new technology called near infrared imaging (NIRI). The imaging system is quite impressive, as it simultaneously records 3D, intraoral color and near infrared (NIRI) images in a single scan.
- It remains one of the best scanners for orthodontic treatment, specifically Invisalign. This is because of its unique Invisalign result simulator feature in which after a full scan of the mouth is performed, the patient can see an example of a possible result after orthodontic treatment.

- It has a modern and stylish design.
- A full arch scan is performed intra-orally in just 25 seconds.
- For caries detection, a second scan is required which is overlapped with the digital model. This is done through the fluorescence technology incorporated in the scanner. A colour map shows areas of fluorescence in which there may be active caries sites. In addition, they will soon launch a scanning tip for the detection of interproximal caries that will be carried out by means of transillumination
- It has intelligent scanning tips, so there is no need to wait for it to warm up to start working.
- It's the only intraoral scanner with a completely wireless option.
- It provides smart advice that lets you know how many times it has been sterilized. Recommended 150 cycles maximum before replacement.
