What are
Porcelain Crowns

Dental ceramics used to restore and replace lost tooth tissue from teeth, or the teeth themselves, have undergone an enormous transformation since the first porcelains appeared decades ago. Currently, what is desired with dental ceramic restorations in Oxnard Dentist is to return the aesthetics, naturalness, anatomy, function, and mechanics of the teeth. There are many types: without metal and with metal, crowns, inlays, fixed bridges, etc. the name, fixed prosthesis, covers all of these types.

Only a dentist knows what type of ceramic material is indicated for each patient while the dental technician is in charge of preparing the prosthesis with the measurements provided by the dentist.

Dental ceramics, commonly used in dental in Oxnard, are basically composed of metallic oxides that when combined or alone are sintered at high temperatures to obtain a solid piece, with a reduced number of pores and mechanical resistance. Depending upon the types and proportions of the metal oxides, the microstructure obtained after sintering can be totally crystalline, glass-ceramic, or predominantly vitreous. This technology plays a crucial role in modern dental in Oxnard practices.

Ceramics are currently classified according to their microstructural composition and their ability to react against acid attack:

- Vitreous ceramics composed mainly of silica (feldspathic): sensitive acids
- Vitreous ceramics composed of silica but with filled crystals (leucite and lithium disilicate, lithium silicate): acid sensitive
- Polycrystalline ceramics (zirconia): resistant acids

There are ceramic metallic prostheses made of a fairly successful material in dental treatments; however, technological advances and a better material appear regularly that meet all expectations for any restoration needed by the patient. This is why ceramic-metallic restorations are gradually becoming a relic of the past; the newest thing is total ceramic. In fact, the only disadvantage is the high cost. Nevertheless, it is ideal for a patient to have in their mouth, but not all patients can afford this treatment. Thus, many times patients choose to allow metal to be inserted into their mouths, even if it is less aesthetic and resistant.

It should be mentioned that metal-free ceramics are more biocompatible and have a low chemical reactivity; metal, on the other hand, can be harmful in the oral cavity.

In the last two decades, ceramics have been opted for as a rule, leaving behind porcelain metal. A patient must know the advantages of the material to choose it. Even if it is more expensive, it is well worth it.

Although these materials are artificial, they closely resemble natural teeth. Thus, they are the ideal ceramic to be used in the mouth.
