What are the types of all-ceramic teeth?

From a medical point of view, there are many types of dentures, and all-ceramic teeth are one of them. All-ceramic teeth are divided into many types. The most common ones are cast all-ceramic teeth, computer-deposited all-ceramic teeth, alumina all-ceramic teeth, zirconia all-ceramic teeth, etc. From the clinical effect point of view, they have many advantages. Not only can they be used for a long time, but they are also not prone to allergies. They can be said to be a blessing for patients with dentures.

1. Casting all-ceramic teeth

Casting all-ceramic teeth is to make the corresponding tooth model with wax, then carry out the high-temperature dewaxing step, and finally melt the prepared porcelain block and cast it into the ring through pressure, and the finished all-ceramic tooth is completed. Simply put, the production process of cast all-ceramic teeth is to take the tooth model and then cast it as a whole. Cast all-ceramic teeth are beautiful, have good translucency, and have refractive properties similar to those of tooth enamel, so the cosmetic effect is closer to that of natural teeth.

2. Computerized ceramic deposition of all-ceramic teeth

With the development of materials science and computer technology, CAD-CAM technology (computer-aided design, laser scanning, and then grinding and production controlled by computer programs) has been applied to the production of all-ceramic teeth. Computer-deposited all-ceramic teeth use computer-cut all-ceramic technology. It uses a CAD/CAM system to deposit ceramics on a refractory mold through computer-aided design and auxiliary processing to form an inner crown, which is then fired at high temperature. Computer-deposited all-ceramic teeth have very high technical requirements. The doctor must have a high level of clinical skills to prepare the teeth to the appropriate shape. The bonding of all-ceramic restorations also requires special materials. In other words, only high-level restorative doctors can master the technology well.

3. Alumina all-ceramic teeth

All-ceramic teeth made using the slurry coating method are made by coating alumina slurry on a refractory tooth model and molding it at high temperature. High-strength and toughness zirconia all-ceramic teeth have been successfully used in heat shielding of space shuttles, brake discs of Porsche cars and artificial transmission belts. Its toughness is much greater than other known non-metallic porcelains, with a wide range of applications and affordable prices.

4. Zirconia all-ceramic teeth

Zirconia is a mineral that exists in nature as baddeleyite. In the 1970s, the famous German company VITA invented the In-Ceram technology. The strength of all-ceramic crowns was greatly improved and soon applied in clinical practice. The realistic aesthetic effect of all-ceramic crowns shocked dentists, and even dentists found it difficult to distinguish which one was a denture. Zirconia all-ceramic teeth are all-ceramic teeth made using the slurry coating method, which is to coat zirconium oxide slurry on a refractory tooth model and shape it at high temperature. Zirconia all-ceramic teeth have been used by more and more people and have been well received by patients and doctors.
