In today’s fast-paced world, patients not only want the best results but also a fast and comfortable experience. To meet this challenge, the contribution of technology in dentistry has become crucial. CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) is at the forefront of this technology. It takes dentistry to a new level by replacing traditional manual processes with digital precision. If you want to increase the efficiency of your clinic and ensure patient satisfaction, it is imperative for you to understand and adopt dental CAD/CAM.

What is CAD/CAM?

CAD/CAM is a revolutionary tool that allows dentists to create restorations such as inlays, onlays, crowns, veneers, and bridges in the clinic itself instead of in a lab. This technology is divided into two main parts:

CAD (Computer-Aided Design): This part uses computer software to create 3D models of teeth. It is based on digital scans of the teeth, which capture every detail with extreme accuracy.

CAM (Computer-Aided Manufacturing): This part controls a milling machine using designs created by CAD. This machine carves restorations from blocks of ceramic, zirconia, or other materials with high precision.

This combination eliminates manual processes, reducing the chance of human error and ensuring repeatable accuracy in every restoration.

How does the CAD/CAM process work?

The CAD/CAM workflow is quite simple and streamlined. The process typically involves the following steps:

1. Digital scanning: Instead of traditional impression materials and trays, you take a digital scan of the patient’s teeth and mouth. A small intraoral scanner rotates inside the mouth and takes thousands of photos, which create a 3D model on a computer screen in seconds. This scanning process is fast, comfortable, and highly accurate.
2. Computer Aided Design (CAD): Once the 3D model is ready, you design the restoration using CAD software. You can precisely customize the shape, size, and occlusal contacts of the crown or bridge. The software also provides optimal suggestions for harmonizing with the natural structure of the tooth.
3. Computer Aided Manufacturing (CAM): Once the design is complete, it is sent wirelessly to a CAM milling machine. You select the appropriate material for the restoration (such as zirconia, lithium disilicate, or ceramics) and the machine carves the tooth design out of the block within minutes. This process works with extraordinary precision.
4. Finishing and Cementation: Once the milling is complete, you can polish the restoration and stain it to make its shade more natural. Finally, you cement the restoration to the patient’s tooth. This entire process can be completed in a single visit.

Various uses of CAD/CAM technology

CAD/CAM is not limited to crowns. This technology is used in dentistry today for a variety of restorations and appliances:

Dental crowns, inlays, and onlays: The most common use of CAD/CAM, which help create high-quality restorations in a single day.

Dental bridges: CAD/CAM is used to design and fabricate long-lasting, precisely fitting dental bridge crowns.

Veneers: CAD/CAM provides exact results for the design and production of aesthetic veneers.

Dentures: This technology is used to make full or partial dentures more accurate and comfortable.

Orthodontic aligners: CAD software based on digital scans designs a series of aligners that gradually move the teeth into the desired position.

Surgical guides for implants: CAD/CAM in dentistry is used to create surgical guides that ensure accuracy during implant placement.

CAD/CAM and the Dentistry of the Future

CAD/CAM technology is not a static tool for dentistry, but an ever-evolving revolution. In the future, we will see a deeper and broader integration of this technology, which will fundamentally change the way dentistry is practiced.

Faster Scanning and Improved Materials

Next-generation intraoral scanners will be faster, more accurate, and more comfortable. This will significantly reduce the time it takes to take an impression, which will be a better experience for patients. For example, the latest scanners now come with wireless and more ergonomic designs, making it easier for dentists to work.

In addition, there are ongoing advances in dental materials science. New, stronger zirconia variants, advanced ceramics and composites are being developed that are not only stronger but can better match the translucency and aesthetics of natural teeth. This will expand the clinical use of CAD/CAM in dentistry not only to the back teeth, but also to the front, aesthetically sensitive areas.
