What is CAD CAM?

CAD CAM stands for Computer-aided Design/Computer-aided Manufacturing. This technology has been around for at least 50 years. It is mainly used in the manufacturing industry to produce high precision tools and parts. It was not until recently that it started being further developed and incorporated into other fields, such as dentistry. Some will say that CAD CAM has been used in dentistry for over 20 years, but only now do we have the technology to support and utilize it to its fullest potential.

CAD CAM technology allows dental professionals to digitally scan the patient’s teeth and with that digital impression, design the restoration on the computer. There are many advantages to this method:

  • There is no need for a traditional impression, therefore it can be a lot more comfortable for the patient. (Check out our earlier blog post about Digital vs Traditional Impression for more details.)
  • CAD CAM technology allows dentists the ability to create a porcelain restoration in only one appointment (same day dentistry). The whole process takes about 2 – 2.5 hours.  There is no need for a second visit to the office as the crown is designed and created in house.

There are 4 main steps involved in the CAD/CAM process

Step 1:

The first step is to take the digital impression. This is done using an intra-oral scanner which takes hundreds of pictures and converts it into a 3-D digital model. This step only takes a few minutes. Again, please refer to our earlier blog post about Digital vs Traditional Impressions for more information about this step.

Step 2:

Next, the restoration is designed on the computer.

Step 3:

Then the data from the design restoration data is sent to a milling machine, where a ceramic block that matches the patient’s tooth color is placed.

Step 4:

About 10+ minutes later, the tooth-colored porcelain is ready to be tried in to ensure proper fit. The restoration is then custom glazed (to match the tooth’s natural color/shade), fired and ready to be bonded to the prepared tooth.

The video below illustrates the entire process: It’s important to point out that, even though this technology is available, it is still a fairly large investment for most offices to obtain it. We, at Chicago Beautiful Smiles, are proud to have the ability to offer innovative, state-of-the-art technology to our patients.

Lastly, refer to our CAD/CAM page for even more information about this technology.

Real Patient Reviews

I have been going to this practice for several years now. I seemingly never have to wait when I arrive at the office and they are all very professional. Dr. Hartlieb and Dr. Ching have been terrific. In addition to doing great dental work, each has a great rapport with their patients. All of their assistants have been top notch as well.

I recently met with Dr. Ching to have some dental work done, and had an exceptional experience at this office! I usually hate going to the dentist, but this experience was different–this office is hands-down, THE nicest dental facilitiy I have ever seen.

- Shaun F.

This dental office is something I haven’t seen before. I had many past dental experiences at other dental offices (unfortunately not good) and finally I found Chicago Beautiful Smiles. Dr. Hartlieb had helped me restore my teeth to a beautiful smile.

- Natasa R.

I am a loyal patient for over (yikes!) 20 years because I appreciate the time, skill and patience of the entire team. As proof of my gratitude, I live in the city and reverse commute every six months for my appointment.

- Dennis H.

Dr. Hartlieb is by far the best dentist I have ever been to. He has transformed my smile into something of beauty. In fact, many people comment on how beautiful my teeth are who do not even know that I have had major dental work performed. I used to never want to smile that large before, but now I smile as big as possible when photographed.

- Fran L.

I always have a great experience when I go to Chicago Beautiful Smiles. The staff is amazing and Dr. Hartlieb and Dr. Ching are extremely knowledgeable and friendly. The facility is incredible and I feel like I’m being treated with the best technology in the dental industry. Go to Chicago Beautiful Smiles for a consultation and I guarantee you will go back time and time again. It does not get any better in the Chicago area.

- Antonio S.

I had a great experience with Dr. Ching – very professional and thorough in his craft. I had been seeing my previous dentist for the past 15 years; however, I am ready to make the permanent switch to Chicago Beautiful Smiles. Dr. Ching is great at explaining the procedures he was performing and made my visit comfortable.
