Cad Cam Dentistry

Dental practice depends on excellent customer referrals. Patients are looking for dental practices that use advanced technologies like Cad Cam in dentistry and offer unparalleled customer service by reducing waiting and operation times.

Cad Cam dentistry has existed for the last 20 years but has primarily been relegated to dentistry laboratories. In the previous decade, patients have seen widespread adoption of technology in the office sphere.

The technology enables the dentist to make dental digital impressions through digital scanners and use 3-D printing to make molds. Cad Cam in dentistry is fast, hygienic, and eco-friendly compared to traditional dental practice methods.

What is Cad Cam Dentistry

CAD stands for Computer-aided design, while CAD means computer-aided manufacturing. The technology lets your dentist take a digital image of your teeth and gums. This is then fed to computer software, which sends this information to a milling machine. The technology is highly accurate, with little chance of error.

The technology was introduced in the 1980s but relegated to lab use. At that time, the Cad cam dentistry equipment was cumbersome and inefficient. With time, advancements in technology led to the adoption of Cad Cam technologies in the dentist chairside.

Before the technology is introduced, restorations would take a week. A prosthesis would be created when the patient visits the dentist, and they would wear it temporarily for a week until the laboratory processes the final crowns. With the introduction of technology, patients could get restorations on the same day.

In-Office CAD/CAM Digital Technologies

As stated above, Cad Cam technologies were relegated to the laboratories for a long time. Introducing modern dental digital scanners, milling machines, and 3-D printing meant that the equipment used was less bulky, leading to wide-scale adoption in dentistry offices. Many dental practices use the equipment to reduce delivery timelines, increase efficiency, improve customer relations, and improve their bottom line as they can now serve more customers.

Dental digital scanners

Before the age of technology, dentists would use old-fashioned impression trays to make dental impressions. However, this technique took time. Dental Digital scanners are used for 3-D digital impressions of your teeth. Dental Digital scanners capture both your soft and hard tissues.

Digital scanners are fast and hygienic. Scanners capture images at a rate of thousands of frames per second. Patients prefer this due to the comfort it provides. The dentist can check the impressions on their computer screens and make changes where necessary. The risk of any distortions is also eliminated, unlike traditional impressions. The impressions created by the dental digital scanner are then sent to the laboratory, where a mold is digitally produced. Cad Cam in dentistry provides an eco-friendly way for dental surgeries.

Dental milling

In the process, the Cad-Cam software will create molds of ceramic or composite resin that closely resembles the tooth to restore. The first part involves taking a digital image of the tooth and the surrounding areas — a Dental digital scanner. The image is then fed to the Cad software for adjustments and modifications. A visual restoration image is created after this. The image is then sent to the milling machines for creation. Stains and glazes are fired into the milled mold to correct the monochromatic appearance.

Dental 3-D printing

Regarding dental 3-D printing, three technologies are used: digital light processing, stereolithography, and material jetting. Each has its own set of pros and cons. Note that the quality of equipment used will influence the final product.

We will begin with stereolithography printing. Here, a laser beam is used on a vat of liquid resin. Some areas of the resin will be solidified, helping to create the mold. You can use this technology on a wide range of materials, and it provides the best finish of the three. Stereolithography printers are amongst the most affordable in-cab cam dentistry labs.

Digital light processing uses a digital projector instead of a laser, similar to stereolithography. While you get a simple workflow with the DLP printers, they are more expensive than stereolithography printers.

The technique used in material jetting is similar to your standard inkjet printer, but the liquid resin can be used instead of ink in this case. Material jetting is increasingly losing its popularity amongst dentists due to its high cost of production.

When selecting a 3D printer for your dental office to ensure that the printer delivers on accuracy, this may force you to spend extra for a quality printer.

Dental Furnaces

Dental ceramic furnaces are used in cam dentistry to produce ceramic dental items like bridges, crowns, inlays, and onlays. The furnaces operate at high temperatures, which helps harden the molds. Technological advances have led to the development of dental furnaces with digital controls. This means you can use it with your cad cam software.

CAD/CAM Software

Cad Cam dentistry software completes scanning, processing, and digitally manufacturing impressionsare. With the Cad cam software, you can draw, design, and manipulate geometric shapes to develop a dental model.

The software uses wireframe geometry to adjust circles, lines, and points. The process of Cad will produce 3-D shapes that you can feed to the CAM for the manufacturing side of the method. CAM converts the CAD shapes into a language that makes it easier for the machines to use during manufacturing.

When you install your CAM software, you will need to wait for the applications to define the cutting paths for the tools used to shape a model to its ideal shape: the software influences what needs to be cut and its speed. During this time, the CAM operator may add specific tools and configure them with the CAM software. Operators use 3D tool paths, hole drilling, and 2D tool paths.

CAD/CAM Advantages and Disadvantages 

If you have not decided to invest in Cad Cam dentistry technologies, you need to check out our pros and cons before deciding. Note the performance of the machinery purchased will depend on the manufacturer. Some equipment offers unrivaled accuracy but is more expensive. Accuracy also depends on the skills and training the dental practitioner suggests.


Improved customer relations

Patients often take time off work to visit their dentist for a restoration. Time is of the essence. Cad cam in dentistry enables digital impressions and printing that saves time. The digital impressions are error-free, which means you will not have customers returning to your office because of an ill-fitting impression.

Fast restorations

The process used in cad cam is fast and efficient. Once you capture a digital impression, you send it to your computer for modifications and final production through the mill. This process enables patients to get same-day restorations. All these processes are completed in-house; you do not need to outsource.


A Dental digital scanner scans 3-D images of the teeth and gums. You can use the scanner for multiple patients without worrying about contamination.

Reduced overall costs

The initial costs for setting up a Cad cam in dentistry can be huge, but when you look at the Return on Investment (ROI), there is an increased value addition. In the long run, the cost of doing a restoration, compared to traditional models, is lower. The lab cost also decreases because you need less staff for restorations.

Precise fabrications

Cad Cam software ensures precise measurements when creating molds. Depending on the quality of the milling equipment, you can create error-free crowns. This saves you money and time perfecting a crown made with traditional methods. There is a vast difference in the final product when you use Cad cam milling machines.


High initial cost

The cost of implementing a cad cam system can be high. It would help if you also allocated some time for training. Dentists who do not have a high traffic inflow will find it hard to recoup the initial investment.

Aesthetic drawbacks

The final mold lacks a natural appearance, leading to people using cad cam dentistry to use superficial staining to change this appearance. You can notice the difference between restorations done through Cad cam and those done through hand-layered porcelain restorations.

Quality of machines

Even though one uses Cad Cam software, there can be variations to the crowns and bridges created. There are instances where you have ill-fitting crowns. The reason for this could be the milling machines’ quality and the user’s experience. More expensive machines are created to achieve higher accuracy levels than others.
