Advantages zirconia ceramic crowns made by CAD / CAM


One of the more controversial sides of dentistry today is the restoration of dental structures with biocompatible materials whole (that is tolerated and accepted by the body).

It also places great emphasis on appearance and resistance materials must be strong enough over the years in front of large forces of mastication and dental extreme pressure (especially if scrasnetelor teeth - so called bruxism).

Discussions about purity material

A very well discussed in the XXI century is the purity of the material. A material that meets at 100% these conditions is zirconium oxide (relatively new for Romania and already the required highly developed countries, due to its special properties).

Besides teeth look hard ceramic zirconium is identical to that of natural teeth, with an advantage in addition to cosmetic dentistry, zirconia has a very high density, porosity 0% excellent biological compatibility - is absolutely bio-inert , is 99.9%, does not change the temperature, has a high resistance (zirconium being used for many years in general practice to achieve prosthetic hip). Patients who are allergic will not have any negative reaction, especially zirconium oxide ZrO2 has a rare and pure composition, do not corrode, has no conductivity electrical and irritating.

Using CAD / CAM technologies

To achieve ceramic crowns zirconia support, the latter being a harder material processed manually, they invented CAD / CAM in short, the most advanced technology vis-a-vis the last performance perfected from year to year. CAD / CAM offers the opportunity to shape the modern technician milling teeth using a computer model based on fingerprinting obtained from teeth.

CAD / CAM - is an entire line consists of 3D scanner technology, 3 computers, milling machine, vacuum cleaner and sintered own, all technology is driven by only a few clicks and working capacity of the machine can be almost non stop, programming is done from a distance through the internet. Results are exceptional CAD / CAM - removing the several stages of preparing technical model, which normally would have taken over a week.

If computerized milling time is only 2-4 days shipping precision of a computer. All procedures completed CAD / CAM help more complete and final part of the tooth, the application of ceramics, which occurs only dental technician. Zirconium and ceramic color is identical (white), which provides an added advantage technician ceramist, enabling them to model layers, play with paper regarding ceramic thickness, color and transparency tooth for satisfaction complete even the most demanding patient.
