Replacing Desktop PCs with Zero-Clients

They used to be called “dumb terminals” but of course nobody wanted a computer that was dumb. So the name was changed to “thin client”. Much nicer, after all according to fashion you can never be too thin. However maybe they are too thin because the new name is “zero client”.

With zero-client computing, what’s old is new again. The whole idea is to move computing back to the data center and away from the desktop. A zero-client environment is often less expensive and easier to deploy

via Replacing Desktop PCs with Zero-Client Solutions – Networking news from Channel Insider.

The thin or zero client is not really a computer but a terminal that allows the user to enter and retrieve digital data. All the computing is done at the server. This is the way all computers networks worked in the pre-PC days. Then personal computers sprouted up on desktops everywhere and networks were developed to connect them and allow multiple PCs to share data. This is what drove the PC computing revolution and is what really brought computing to clinical dentistry.

Now new technology is pushing things in the other direction. The latest trend is to create a virtual desktop machine on a server and distribute it to thin client terminals throughout the office. The server can be a machine in the office or a machine in the cloud. There are some definite advantages to this, especially for the IT service provider.  On the other hand at this time most dental software is not designed to work optimally in a zero client environment. In fact most dental software vendors will tell you their software will not run as a thin or zero client.

Never the less I have spoken with several advanced dental IT service providers who have set up virtual desktops with thin client services for dentists and they claim they are working fine.

Simple data transfer like chart notes lends itself well to thin client computing.  Images are another story. It is easy to transfer images from server to terminal but image capture and manipulation takes lots of computing capacity that most zero client applications are not designed to handle.

I do not suggest you run out and demand your computer IT provider switch everything out to zero client. There is a real difference between leading edge and bleeding edge and at this time zero client is somewhere in between. However it is good to be aware of these changes and to look to the future.

Dr. Emmott. You are absolutely correct. I do believe that Dental technology is heading that way.
Here at Sunset Dental Technologies we implemented VDI for some of our client and took Open Dental, Dentrix, Softdent, and Eaglesoft to the cloud. Our solution include DEXIS, Apteryx, Schick, and Planmeca integration so, usb or IP sensors could be used with “thin clients” or even “zero clients”. Our VDI solution allow doctors to connect to the VDI client from anywhere at any time (even from inside somebody else clinic) and use local xray sensor to take a xray-shoot straight into VDI cloud system.

Good article.
Thank you.
