DENTAL ONLAYS Meaning and
Definition
-
Dental onlays, also known as dental overlays, are a type of dental restoration that is used to repair and restore damaged or decayed teeth. They are considered a more conservative alternative to dental crowns, as they cover only a portion of the tooth's surface rather than the entire tooth.
Dental onlays are typically fabricated in a dental laboratory using materials such as porcelain, composite resin, or gold. The process involves taking impressions of the damaged tooth and sending them to the lab, where the onlay is custom-made to fit the specific dimensions and shape of the tooth.
Once the onlay is ready, it is bonded onto the tooth using dental cement. Unlike dental fillings, which are directly applied to the tooth, onlays provide a more extensive restoration by covering the cusps (raised points) and one or more surfaces of the tooth. Onlays are particularly beneficial for teeth that have large damaged areas or extensive decay, as they provide added strength and protection to the tooth structure.
The main advantage of dental onlays is that they preserve a greater amount of the natural tooth structure compared to dental crowns. This conservative approach helps to maintain the tooth's integrity and strength while providing a durable and aesthetically pleasing restoration. Dental onlays are also beneficial in cases where the tooth's cusps are damaged, as they offer better support and strength to withstand regular chewing and biting forces. Overall, dental onlays are an effective and long-lasting treatment option for restoring damaged teeth and improving overall oral health.
