Computer aided design (CAD) and computer aided manufacture (CAM) have become an integral part of our lives. Not many people realize that these two approaches have changed the world of healthcare and dentistry in particular.
Once any tooth structure is removed, it is necessary to create one as close the natural tooth as possible. That’s where CAD and CAM come in. These technologies allow the dentist to draft and create two- and three-dimensional models of inlays, crowns, bridges, and onlays.
Besides being highly precise and keeping the material costs to a minimum, CAD and CAM save the dentist’s time and improve the patient’s satisfaction. The new tooth structure can be drafted within minutes and shown to the patient in order to get the approval. The time of prosthetics manufacture is also reduced thanks to CAM.
CAM/CAD Dentistry: How Does it Work?
A special program creates a 3D model of the patient’s teeth and gums allowing the dentist to proceed with precise tooth restoration design. Besides making the new tooth structure functional, CAM/CAD allows the dentist to deal with the aesthetic side of the issue.
Once the new structure is designed, it’s sent to the sculpting equipment, which proceeds to create the required crown, bridge, inlay or any other material using CAM technologies.
The impression taking is now in the past. CAM/CAD made it possible to eliminate the need for temporary structures or the healthy tooth structure reduction in order to fit the prosthetics. The precision of dental products made using CAD/CAM technologies is much better than of hand-made materials made in a dental lab.
Expert dentists from Bajars & Bajars Dental Clinic in San Diego report that after implementing CAM/CAD technologies, the patient satisfaction has increased threefold. Instead of coming back for several repeat appointments, a patient can have a tooth made in just a couple of hours. Since spending time in the dentist’s chair is one of the least favorite things on any person’s list, the speed and efficiency of the procedure is highly appreciated.
Single Day Porcelain Crowns
The most popular use of CAD/CAM technologies in dentistry today is the same day porcelain crown. There is no more need for temporary plastic crown installation while waiting for the permanent structure to be manufactured in the lab by technicians, who have never even seen the patient.
CAD and CAM technologies are making a revolution in the world of dentistry. More is yet to come.
