Traditionally, if crowns, onlays, inlays or dental veneers were required to restore damaged teeth, multiple procedures and a great deal of waiting time in-between would be inevitable. E4D PLANMECA creates these ceramic restorations within minutes in the dental office. This means that many treatments can be completed in just a single visit. These restorations are metal free so have no dark lines. Since the procedure is completed in one visit, apprehensive or busy patients appreciate this technology.
E4D is comprised of computer-assisted design (CAD) tools and a computer-assisted milling (CAM) machine that creates custom ceramic restorations.
How can E4D benefit me?
E4D can benefit almost anyone needing a ceramic restoration. It allows for an esthetic restoration that is conservative with tooth structure. Exceptions include patients who have a prior history of breaking ceramic restorations and those with a deep bite. E4D restorations are proven to last for over 5 years, but recent research indicates that most E4D created restorations last for more than 10 years.
Additional advantages associated with E4D include:
What is the E4D system comprised of?
No temporary restorations
High-quality ceramic products
Less injections and discomfort
Fewer dental visits
More natural tooth is saved
Long lasting restorations
The E4D PLANMECA System is sometimes called a CAD-CAM system. CAD-CAM means Computer Assisted Design and Computer Assisted Milling. The E4D system has three major components:
Acquisition device: This device is home to a high-quality camera and a medical grade computer. The function of this unit is to photograph the prepared tooth. Three-dimensional images are created of the tooth on the screen, which the dentist uses to design the perfect ceramic restoration.
Three-dimensional CAD software: This software allows the dentist to examine the tooth from every angle. It is the closest possible thing to holding the tooth in the hands and rotating it.
Milling device: This unit actually manufactures the custom restoration from the specifications entered into the computer. A ceramic block that best resembles the existing tooth color is chosen and placed into the unit. Within minutes, the milling device produces the restoration the dentist designed.
What does a E4D restoration procedure involve?
The first step in the procedure is preparing the tooth for the restoration. Using the E4D scanner, the dentist will take a video image of the tooth and surrounding structures, sending a three-dimensional, colored model to the E4D computer.
These images are transposed onto the computer screen, where the dentist will view the tooth from every angle and design the final restoration. When the design is complete, it will be transmitted to the milling unit.
The dentist will insert a block of ceramic, matching your tooth color, into the milling machine which will then create the full crown, onlay, inlay, or veneer. Before affixing the restoration to the tooth, the dentist will perform a dry fit to ensure comfort. Once a perfect fit is established, the restoration will be polished and affixed to the tooth with dental cement.
