DENTAL INLAYS AND ONLAYS
WHAT DO TEETH INLAYS AND ONLAYS REPRESENT?
Dental inlays or onlays are used for the reconstruction of teeth that are slightly to moderately affected by caries. They are also used in cases where the tooth is cracked or damaged, in situations where the damage is not so great as to use a dental crown. Most often they are made of ceramics, composites but also of gold.
Dental inlays are used for cavities or cracks located on the upper surface of the tooth. They are made in the color of teeth, and are often used as a replacement for black amalgam fillings to achieve a better aesthetic of the teeth. Dental onlays are used in cases where the caries engages a larger tooth surface and when it is necessary to replace the larger part of the dental crown.
The procedure of setting an inlay or onlay begins with the cleaning of the teeth and the removal of caries. The print is then taken to the laboratory where the inlay or onlay is made from any of the materials mentioned. Until the next visit, the dentist closes the tooth temporarily. When the inlay or onlay is finished, it is carefully placed on the tooth and attached with strong resins.
Because the inlays and onlays are made on the basis of a personalized impression, they allow the structural strength of the damaged tooth to be retained, prevent the bacteria from entering and the formation of cavities. The advantages of dental inlays and onlays over conventional fillings are the following:
• They are made in tooth color and are almost invisible.
• They are more resistant to temperature changes and in general, so they can last 30 years or more.
• They require much less tooth grinding than a regular filler.
• Protects the damaged tooth for a long time, increasing its resistance and hardness by up to 70%.
