Dental compressors are the materials used in dentistry as a restorative material. They were introduced in the early 1990s as a hybrid of two other dental materials: dental composites and glass ionomer cement. They are also known as polyacid-modified resin composites. They are used for restoration in areas with low voltage

History

Kompomer was introduced in the early 1990s. Previously available restorative materials include dental amalgam, glass ionomer cement, resin modified resin ion cement and dental composites.

Composition

Compomer compositions are similar to dental composites but have been modified, making them modified composites. This resulted in compomers still needing a bonding system for bonding to the dental tissue. The compomers contain poly-modified monomers and silicate glasses that release fluoride. The acid-base reaction occurs when the compomers absorb water after contact with saliva, which facilitates crosslinking and fluoride release structures.

Features

Fluoride Release

The compressor releases several fluoride ions, such as glass ionomer cement. This fluoride release rate is only about 10% of the glass ionomer, which makes it less useful for decidative restorations. It has been shown to have no advantage over amalgam restorations with a fluoride-releasing bonding agent, which releases mercury and fluoride. Compomers also lack the ability to 'refill' their fluoride ion content with topically applied fluoride from toothpaste etc., such as glass ionomer cement; this is another limit of their efficacy. Compressors are recommended for patients at risk of developing caries.

Handling

Handling and ease of use of composites are generally seen both by dental professionals. The compomers are available in a normal and flowable form, with manufacturers of flowable composites claiming that they have the ability to form into cavities without the need for hand instruments.

Aesthetics

Compomers are dental colored materials, so their aesthetics can be directly viewed better than amalgam teeth. It has been shown that ratings in various aesthetic fields are better for composers than modified modified ionomer cement glass. Kompomer is also available in a variety of non-natural colors from various dental companies for use on primary teeth.
