All Porcelain Inlays Onlays

All Porcelain Inlays Onlays

All Porcelain Inlays onlays are two types of fillings used in back teeth. Inlays fill cavities which restore strengthstability to damaged teeth.

They are molded to a precise fit and have a very realistic appearance. Onlays cover the entire surface of the damaged tooth and are used when a tooth is too decayed for regular fillings or inlays. When doing inlays or onlays the cavity of the teeth is prepared and a precise impression is taken , this impression is sent to the laboratory and a porcelain structure is fabricated , this structure is then cemented to the teeth .

Inlay- Onlay

When more than half of the tooth’s biting surface is damaged , the dentist will often use an inlay or onlay to correct the problem An inlay is done when the tooth structure replaced is within the cusp tips of the tooth. If the damage is more extensive and the new structure covers the entire chewing surface including one or more tooth cusps, the procedure is called an onlay

Inlays and porcelainonlays are applied in two dental visits. At the first visit, the old filling, or decay, is removed, and the tooth is prepared for the inlay / onlay. The dentist will then make an impression of the tooth, and send this impression to a dental laboratory. This impression will be used by the laboratory to construct a custom-made porcelain At this time the dentist will place a temporary sealant on your tooth and schedule a second appointment. At the second visit, the temporary sealant is removed. Your dentist will then ensure that the inlay fits properly in the tooth and does not interfere with your bite. The inlay/ onlay is then bonded into the tooth with a strong bonding resin, and polished smooth.

Traditional fillings can reduce the strength of a natural tooth by up to 50%. As an alternative, inlay and onlay, is bonded directly onto the tooth using special high-strength resins, can actually increase the strength of a tooth by up to 75%

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.

Aesthetic Studies;

Porcelain Laminates

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.
