In hopes of providing efficient, long-lasting services that please patients. Dentists have turned to new technologies such as digital impressions for assistance. As well as in-office CAD/CAM restorations in order to improve your smile. These are awesome practice enhancements that result to be both consistent and long-lasting.
All dentists have struggled throughout the years with porcelain fractures. As well as debonding, tooth failure around restorations, microleakage, and less-than-ideal aesthetics. In the past digital technology, software and hardware limitations resulted in tooth problems. Such as teeth that looked unnatural. Yet, we now have restorations that are aesthetically pleasing. While also prove excellent clinical performance.
There has been a significant improvement in digital systems, restorative materials. Preparation parameters, philosophy, and cementation techniques have also improved tremendously. Lithium disilicate is a universal bonding agent and dual-cure self-adhesive resin cement. These innovative dental materials have become the cornerstones of CAD/CAM success.
Uses
The primary use of CAD/CAM systems by dental laboratories is a single unit and multi-unit crown and bridge restorations. CAD/CAM systems used in dental applications generally consist of 3 modules. First, a scanner takes an impression model and converts the model into digital data. A design software package used to design and change the digital model. As well as a milling machine, this mills the designed model using a selected material. These types of CAD/CAM systems are able to fabricate many varieties of restorations. At lower costs, while maintaining good quality.
Intraoral imaging and computer technology are also used. This helps fabricate dental restorations in the dental clinic to shorten treatment time. Precise optic lenses capture the shape of the tooth preparation. The dentist then designs the virtual model using CAD software, and then a milling machine. This machine is in charge of milling the restoration from a block of ceramic material. Finally, the dentist bonds the milled restoration into the patient’s mouth. The complete procedure takes approximately one hour. The materials used in the CEREC 3D system are close to natural teeth in strength, beauty, and function. Indications include inlays, on lays, veneers, and crown restorations.
Procedures consist of
Existing restorations and decay need to be verified with a cavities indicator solution. Then a full-coverage tooth preparation using a new single-use tapered diamond bur. Long-term patient comfort is achieved by the use of single-use, high-quality, low-heat-causing burs. The cost of single-use burs is somewhat low and worth the positive effects.
Dental CAD/CAM systems have advantages that cannot compare in strength to materials and precision of the restorations These materials are better in quality, strength, and durability than those used to make traditional dental restorations. During the milling process, materials are not subjected to high temperatures. This is to avoid irritation or malformation due to heat. Dental restorations fabricated from CAD/CAM systems have greater strength than porcelain materials. Restoration ís precision. Thanks to the accuracy of the scanner, software, and milling machine in a CAD/CAM system. The fit of dental restorations is quite predictable.
