Various intraoral scanners were introduced in IDS 2019. I have evaluated these intraoral scanners and organized them in a table. My subjective opinion may be included, so please consider it.
Last year I compared 9 intraoral scanners and published at J Prosthet Dent. (https://goo.gl/gpFz4x) Now I feel a little impatient thinking that I need to give objective data again with the newly introduced intraoral scanners.
I usually use intraoral scanners in my daily practice. There is some occasion when I feel that scan is not perfect at the deep gingival margin. In this reason, I looked closely to find if there was a brand that came up with a solution for this. An experimental scanner called the ’V-IOS’ is under development, and the developer there gave me information that it would be available at the end of this year. However, at present, the 'i500' intraoral scanner seems to be realistic in that it has an impression add-scan function. I could replace scan data around the margin area with impression scan of small impression body of this region.
'Trios 4', 'Emerald S', and 'iTero Element 5D' introduced a new feature that covers preventive dentistry. They utilized a fluorescent lamp to look at the surface caries, and they also had proximal caries detection function with a transmission light. iTero used its own technology called NIRI and could detect caries after just one scan without tip replacement. The other systems needed another scan and transillumination tip replacement for this purpose.
The size and weight of the scanner wand was also of my interest. Dental Wings introduced 'Virtuo Vivo' with completely changed design, and the wand itself was small and light. Dental CAD-CAM founder Duret's 'Condor' system had a scanner tip that was almost as small as a toothbrush.
Virtuo Vivo is faster than previous versions, but Condor is a little bit disappointing in terms of accuracy and speed.
What I have noticed this time is that hardware such as subsurface scanning device has not been completed yet, but the software to make more effective use of the already existing technology has been developed steadily.
We hope that more convenient and accurate intraoral scanners will continue to be developed and used in clinical practice.
