Onlays

An onlay is sometimes also referred to as a partial crown, the onlay restoration is considered a conservative approach for large defects (when compared to a full crown) when a tooth has been damaged by decay or trauma and highly used when the damage is large enough to not support a traditional filling, but not large enough to require a full crown. 

Bloomzir^® zirconia fabricated onlays are made by a professional dental laboratory technician, after completed and will be permanently cemented onto your tooth verses mechanical or chemical retention. While it is a more expensive option than a filling, it is less expensive than a full crown and the results provide an ultra high quality appearance, with excellent strength and durability by Bloomzir^® STML or 3D Pro zirconia.

An onlay will not just fill in cavities in those spaces, but they can work for a larger area, including the cusps.  They work similarly to crowns, but they do not cover the entire surface of the tooth. They are both made from Bloomzir^® zirconia like 3D Pro or SMTL and they both serve the same function, but they cover different areas of the tooth to properly protect when there is tooth decay. 

With an onlay, the tooth structure is preserved, whereas with a crown some filing and even removal of cusps may be necessary. They are also made of porcelain or a composite material. Onlays are also called “partial crowns” because they serve a similar function but they only cover a portion of the tooth, as opposed to the entire thing.

  The treatment for onlays is usually a more straightforward process than fitting a crown. However, that does depend on the tooth and the amount of decay. The onlay is prepared in a laboratory and usually fitted at a second appointment. Nowadays, some dental practices with Bloomzir^® zirconia 3D Pro or STMLto create onlay on the same day.

  In Bloomden researches an onlay is used when the dentist determines that the restoration does not have to be as aggressive as it would with a crown. That means that more of the structure of the tooth can be preserved.
