SprintRay 3D Announces the $2 Crown

 



For the past several years... in fact almost since the invention of 3D printing, people have asked, "When will the 3D printed crown be here?"

3D printing has been around for quite a while now.  It began to show up in dentistry (in very limited applications) about 10 years ago and has continued to make inroads in the industry since that time.

We got involved with the technology about 3 or 4 years ago.  We loved the idea of taking digital scans with our iTero system and then using our SprintRay 3D printer to create the models.  The process was faster, more accurate, and more streamlined than impressions, stone, and trimming.

Over the time that we have been doing 3D printing, we've found it to be an incredible benefit to our practice.  We went from printing models, to making surgical guides, alingers, occlusal guards, almost anything that we were previously creating with analog workflows.  It's amazing to compare the analog lab to the digital one.  The analog lab is dusty and messy.  Dealing with bags of dental stone that are a light, fluffy powder which gets easily airborne, it's easy to see how our lab is routinely covered with a thin layer of "moon dust".  Combine that with mixing that powder with water, shaking it into impressions, and then trimming the resulting models, the analog process has "mess" written all over it.

It's fairly easy to see that 3D printing is a much easier and much less messy option that we have fallen in love with.  Yet for all of its benefits, there has been one elusive piece of the 3D printing equation and THAT has been creating permanent restorations.  There are lots of materials available to create with, but none have had the durability to be classified as permanent restorations.  Now for the first time we are seeing a truly "permanent" material.

The material is called Bego VarseoSmile Crown Plus.  It is a resin that exhibits strong flexural strength, wear resistance, and polish ability.  It is NOT a porcelain or Zirconia, but the material does show that it is resilient enough to be in the oral environment long term.

In my mind (this opinion is mine and mine alone) it appears to be a material that is similar to heat cured composite materials we have seen in the past which are used for permanent prostheses.

You can get more info from this link.

One thing is for sure at this point.  The dam has broken in the market.  We will now see a tremendous amount of research and development in this area of the profession.  Usually when we reach this magic point, we see a "gold rush" of companies bringing similar. products to market.  The next year or so is going to be interesting!
