Permanent dentures are made from different materials. Without question the best material is porcelain, which is neutral to tissues and in the same time, does not wear off and overcolour. The always-evolving techniques give the possibility of burn the porcelain on different type of metals.
Sometimes the choice of a metal depends on the prosthetic dentures already in the oral cavity of a patient, as the potential differences of voltage can cause unpleasant symptoms wildly known as the electrometalose. That danger is now being eliminated by the more common usage of the porcelain caps and bridges burnt on the titanium. This is an extremely durable metal, is light, it doesn't conduct heat and is absolutely biocompatible.
The novelties are the caps and bridges done entirely of ceramics without the use of metal component. It gives them extreme transparency and the distractions of light the same as the natural tooth tissues. Because of their especial aesthetic effect they are preferred especially in the anterior portion of the oral cavity.
The saying that permanent dentures are harmful because they require polishing the tooth and that the teeth under caps decay, widely known among patients are not true. The usage of anaesthesia, modern polishing techniques, precision impression masses and laboratory techniques enable the opportunity to make a precision, perfect works. Properly polished teeth sustain its durability, and a cemented cap isolates the tooth tissues from the oral cavity environment.
The new generation of cements used nowadays excrete fluor for a few months impregnating the remaining part of the tooth. The possibility of equipping the patient with a temporary denture gives him an option of not having to change his everyday living. In the particular situation when the amount and quality of the remaining teeth does not give the ability to make a permanent denture the alternative treatment is the movable dentures (prosthesis). It can be acryl prosthesis - more extensive, or skeletal - with a limited plate. Sometimes there is an option or a necessity to use both methods: permanent and movable simultaneously.
The movable prosthesis are not as comfortable as the permanent ones but because of the prosthesis plate which lies on the alveolar processes the forces that originate during chewing and biting are diverted on a larger surface, in the same time protecting the weak or few teeth. Telescopes, bars and locks can now replace clamps that are not aesthetic and not easily accepted by patients and are used to put the prosthesis into place. They all give very nice visual effect and at the same time they avoid the problem of rubbing the teeth by clamps.
Occasionally we also make immediate prosthesis. If a tooth in the anterior compartment needs to be taken out a doctor can make the impression before the extraction, then the technician takes the tooth out on a model and makes the prosthesis as if the tooth wasn't there. So after the extraction the patient gets out from the dentist with the denture avoiding the unnecessary stress. The immediate prosthesis has many advantages: the wounds heels faster, the pain is less acute, and the alveolar process is provided with a functional impulse deteriorates in a lesser grade.
