All Porcelain Crowns
All porcelain Crowns, also known as caps, slide over teeth to hide misshaping, misalignment, cracks, discoloration,other imperfections.
CROWN: A crown is a restoration that covers, or “caps,” a tooth to restore it to its normal shape and size, strengthening and improving the appearance of a tooth.
BRIDGE: A bridge is a dental appliance that replaces one or more natural missing teeth,thereby “bridging” the space between two teeth.
If you’re missing a tooth or more, you may find that there are other things you miss. You may miss your natural smile. Naturally, the effect of tooth loss varies from person to person and depends on what exactly has been lost. The root anchors the tooth in your jawbone, providing stable support for the crown. Without the root, the bone around the lost tooth may gradually recede, remaining teeth may shift and chewing may become more difficult with time. If you’re interested in replacing your entire tooth,your option is dental implant or bridge restoration.
Standard metal & quotnı-co or precious metals & quotau can be used as infrastructure.Gold is the most precious and biocompatable material.Therefore aplications using precious metals get more healthy and esthetic results.
They are made from reinforced porcelain. Although many things affect the appearance of crowns,the most important thing is their reaction to the light.Natural teeth are transparent and pass the light.As this result the natural teeth have depth and vitality.Full-porcelain crowns can also pass the light and their appearance are like the natural teeth.Metal porcelain crowns show dark areas in some lights(flash,discolight).They are cemented mechanically,but full-porcelain crowns are cemented both mechanical and chemical adhesion and this adhesion is much higher than metal-porcelain’s.Infrastructure does not include metal ,so there is not a dark line at the level of gum.It provides more esthetic image. When the gum recesses,full-ceramic crowns protect their esthetic appearance,but metal-porcelain crowns create a bad image in the region.Allergic reactions dont occur in full ceramic crowns.
In this system the reinforced porcelain are pressed in the special IPS maschine.They were prefered especially for the front area.They are translucent and esthehic.But they can not withdraw very high chewing forces,so they are not proper for the back area.
The infrasstructure is zirconium and it is white-colored and can withstand chewinf forces.It can be achieved an esthetic result especially in the back area.
Crowns decrease physical discomfort in teeth and offer extra support to those that are weak or damaged. They can also vastly improve the overall appearance of your smile and make your teeth much more durable.
It is one of the aims of dentistry to restore lost tooth tissue, aesthetics and function, to provide biological harmony. Porcelain is the most used restorative material with its aesthetic, tissue-friendly and appropriate physical properties. However, metal-supported porcelains developed to strengthen the physical properties of porcelain, the presence of metal infrastructure It does not have sufficient aesthetic and biological compatibility as porcelains without metal support.
It is the technique of bonding a specially prepared porcelain layer in nail thickness, desired color, size and form to the front face of the tooth. In this method, unlike porcelain crown application, healthy teeth are not prepared much. Instead, a very thin tooth layer is removed only from the front of the tooth and the prepared porcelain lamina is adhered to the front of the tooth with special bonding techniques.
Scope of application:
With this technique called ‘laminate veneers’, only the front surfaces of our teeth are removed less than the amount of material taken in a filling and to make perfect color and texture compatible applications.
When the destruction of the teeth is excessive, the entire tooth is covered with a porcelain crown, porcelain crowns can be full porcelain or metal supported. Full porcelain crowns look more aesthetic and natural than metal-supported porcelains.
How are aesthetic fillings made? Aesthetic fillings are placed in prepared cavities layer by layer and each layer is cured with a special light. When this process is finished, the aesthetic fillings are shaped and corrected according to the tooth. All these processes take longer than amalgam filling. However, it is at least twice as expensive as amalgam. The duration of aesthetic fillings in the mouth is 7-10 years, which is close to the life of amalgam. However, amalgam is in favor of very large fillings.
Advantages and disadvantages: The biggest advantage of these fillings is their aesthetics. In addition, since these fillings are well connected to the teeth, they support the dental tissues and prevent fractures and heat. Composites can be used not only to restore caries, but also for their cosmetic effects by changing the color and shape of teeth. The most important disadvantage is the post-procedure sensitivity. The colors of the fillings may change slightly with coloring foods such as coffee and tea.
Zirconium crowns and bridges use zirconium, which is a white material instead of metal, as the substructure. Aesthetically beautiful, durable crowns and bridges are obtained by processing porcelain on it.
