Feldspathic ceramic veneers
This type of veneer is counted as one of the first used for cosmetic dental work. They are outstanding pieces for preserving the naturalness of the smile, maintaining its color and not generating adverse reactions in the oral tissues.
To some extent, the results in terms of color , size , texture and durability were considered unsurpassed . However, with technological advances, the use of these veneers has been on the decline . Compared to other types of veneers listed below, feldspathic veneers are more susceptible to fracture . They also require great precision at the time of making the diagnosis, otherwise, the result could be different than expected.
Aluminous ceramic veneers
From a chronological perspective , the aluminous veneers are the ones that follow the previous ones . The development of this kind of porcelain was focused on improving the formula of feldspaths, giving them greater resistance . The modification was so successful that all-ceramic crowns could be created, matching the metal-ceramic systems.
However, the increase in the hardness affect transparency, which was one of the most attractive features in ceramics . This is the reason why, normally, they are used for the creation of internal structures, which are then covered with veneers of less opacity.
Following chronological order , they rank third in implementation and development. Because their structure gives them both rigidity and hardness similar to glass , they are called glass-ceramics . The biggest drawback of the pieces made with this material is that it is difficult for them to acquire the desired pigmentation . In such a way that, for the pieces to have the final color, a colored glass cover must be applied.
Zirconia ceramic veneers
This is a material edge , it focuses on the oxide of zirconium (metal) highly synthesized. This formulation is also known as zirconia or zirconia, considered ceramic steel . Like the aluminous ones, this is a very opaque material, so it is usually used for the rehabilitation of posterior teeth, mainly.
The veneers Lumineers are made with ceramic feldspathic improved . The most innovative thing about this system is that it is not invasive , since it does not require the teeth to go through conventional preparation. This is based on the reduction of the dental structure by filing the teeth until they are greatly diminished.
Another characteristic feature is that they are of lesser thickness than most veneers, its thickness is similar to that of a lens of contact . It has properties to strengthen cracked or weakened enamel , just as its white color is permanent.
Lithium disilicate veneers
The lithium disilicate also pertains to materials dental the art . Like Lumineers, they are ultra-thin , 0.3mm thick and with a strength similar to hybrid composite resins. They adhere properly to the teeth and are highly biocompatible , so they do not irritate the gums. This type of material has corrected the opacity resulting from a high resistance and maintains the translucent properties, as well as a good appearance.
