Technology T-cam

Requirements confronting dental laboratories are increasing daily. A dentist looks for solutions that will allow him to achieve the best aesthetic and functional results. Likewise, the patient is looking for a doctor who will help him fulfill his dream of restoring a beautiful smile.fal005000223.jpg
Over the centuries, various innovative prosthetic materials have been developed. Through time, they have changed and were influenced by fashion. People replace teeth with many different materials - bone, stone, ivory, silver, gold, pearls and porcelain. For almost 20 years, specialists have looked for technologies and materials that will be compatible with a patient’s body, be durable, have a stable color, and, above all, permit the achievement of aesthetic perfection. Permanent restorations of zirconium oxide are among the most modern and fastest growing aspects of dentistry. Prosthetic restorations based on zirconium oxide combines functionality and, above all, that which is so important to us, aesthetics. Porcelain crowns of the highest caliber, fulfilling the requirements of functionality and aesthetics, and eliminating metal, are built on a T-CAM core containing the most precious material, zirconium oxide.
Zirconium oxide has had medical applications since 1990. This was a lengthy period, during which research studies and observations did not detect a single case of allergic reaction to the material. It became a good enough reason to start using zirconium oxide in even the most allergy-sensitive patients. It is also important that zirconium oxide acts as an insulator when in contact with heat and cold, as well as showing no signs of interaction with other dental materials. This explains why zirconium oxide has become a base for the implementation of the T-CAM cores for porcelain firing. In our everyday contact with others, we want to keep our teeth looking white and natural. We hope that, on a sunny day, our “third” teeth will reflect the light in the same manner as our natural teeth, and add charm to our appearance. A property of enamel is that, when light rays hit it, the brightness, effulgence, and transparency of the tooth are visible. We are seeking a material with enhanced properties and high strength, which will result in capturing the light in a manner similar to natural tooth enamel. Currently, half the success we achieve is through the use of modern porcelain, which is almost identical to the material from which our teeth are built. Combining this with zirconium oxide cores has led to obtaining the aesthetic effect of natural teeth. Zirconium oxide is one of the hardest materials known, and zirconium has a brightness nearly identical to natural dentition. This allows us to create T-CAM cores that show an attractive smile. And, thanks to that, prosthetic restorations can be shaped in such a way that no one would distinguish them from real teeth. An additional advantage of zirconium oxide is that it is less prone than metal to the accumulation of plaque. Zirconium oxide makes a white core, which is a big advantage in the aesthetics of a restoration. Thanks to this, crowns or bridges built on a T-CAM core, match neighboring teeth in a way that becomes indistinguishable and harmonizes with the natural teeth.afa005.jpg
Zirconium oxide (ZrO2) is a new material for making cores for full ceramic prosthetic restorations (posts, crowns, and bridges), as well as abutments for prosthetic restorations based on implants. Thanks to the modern technology of CAD/CAM, this material almost perfectly fulfills the requirements of modern prosthetic restorations. Zirconium dioxide, stabilized with yttrium in a tetragonal arrangement, is a highly bio-compatible material, provides high strength, and can be used in all areas of the mouth. Although results of long-term tests using this material in dental prosthetics have not been shown, current tests have yielded very positive results. In vitro and in vivo studies conducted in recent years, show that the surface of zirconium ceramic accumulates less bacteria than pure titanium. Other experiments have shown that zirconium oxide is only half as likely to fracture as aluminum oxide, another material used to perform full ceramic restoration cores. Zirconium oxide’s unusually high resistance to bending (1000-1200 MPa) and cracking (10 MPa m), are a result of its highly fine-grained structure (the diameter of particles is 0.3 - 0.5 μ m) and chemical modification (stabilization with yttrium trioxide). These properties make our T-CAM product – zirconium cores for non-metal restorations, a great alternative to traditional prosthetic restorations.
