Bio-Compatible Materials

Bio-Compatible Materials

In dental practice, it is of great importance to determine the biological compatibility of dental materials. Bio-compatible materials are items that can be used in close contact with living tissues of the human body. They are used in evaluation and treatment of body organs, tissues and functions. In dentistry, there are different materials that are used to treat various dental problems. However, in order for them to be use, they must undergo some testing and determine their biocompatibility.

There are basically three levels of biocompatibility which include:

• General

• Immunological

• Bio-energetic

General biocompatibility focuses on the general reaction of the material with the tissues of the human body. Will use of the material cause any poisoning of body’s cells? This is the question that is addressed when determining the general biocompatibility. Immunological biocompatibility determines compatibility from an individual’s reactions to the material. The bio-energetic biocompatibility determines how the material will interact with the body organs on an energetic level. Materials that are energetically incompatible will cause interference on the meridians that are associated with the teeth that are being restored.

Selecting biocompatible material for dentistry

In order to select bio-compatible materials of the best compatibility start off with materials that show low levels of toxicity to cells then proceed by eliminating those that exhibit an immunological response. Narrow down farther by selecting from the remaining materials using either Applied Kinesiology or Electro Dermal Screening. Taking these steps to determine compatibility will produce the best non-reactive, compatible material.

Common dental filling materials

Dentists use a whole lot of materials to repair damaged teeth. They range from amalgam and galloy to direct composites and porcelain inlays. Amalgam has to be the most commonly used material when it comes to the back teeth. This is because it is easy to install compared to the other materials. Amalgam is made up of about 50% mercury and varying percentages of silver, copper, zinc and tin. It is cheap and takes very little time to place. However it corrodes very easily with a lifespan of at least 5 years and at most 10years.

Galloy is a material whose popularity is up coming. It is made up of silver, copper, tin, gallium and indium. It is a mercury-free option to amalgam. The fact that amalgam contains mercury which is a neurotoxin has raised lots of skepticism against its use. Direct composite and the indirect composite inlay function the same way however the installation of these bio-compatible materials is different. The direct composite is simply a special kind of plastic that will bond to the tooth. It is easy to repair and it is colored the same way as the tooth requiring less trimming of the tooth structure. It takes more time to place than amalgam and thus is more expensive. Indirect composites on the other hand are perfect whenever a perfect fit is necessary. They are 2-3 times more costly than amalgam filling.

Porcelain is also a bio-compatible material used to rebuild broken teeth and even replace missing ones. It can be used in any part of the mouth with such tremendous ease but not in the same league as amalgam. In fact placement of dental porcelains is almost as similar to the indirect composite.
