Biological dentistry-metal-free restorations

The so called biological dentistry is a newly emerging holistic approach, which looks at the body as a whole unit. The basic principle of this approach is that the oral cavity is an integrated part of the body, and problems in the mouth can have an effect on other organs as well.

The cornerstone of biological dentistry is the use of non-allergenic materials.  These materials harmonize with the body, and apart from the obvious health gain, we can achieve much better function and aesthetics, than with the use of conventional materials. Metals (amalgam fillings and metallic restorations) are the most common allergens in the mouth and their elimination from the mouth is essential in order to prevent allergic reactions.

Metal-free restorations can have further advantages. Metal alloys make the pH of the mouth acidic and release metal ions, which can be harmful for the body. Metal restorations can cause greyish discolouration of the gum, which is not aesthetic. Amalgam fillings may dissolve, which can lead to various health issues. Therefore, their use is limited in both biological and conventional dentistry. Consult your dentist about alternative tooth filling materials and the removal of your amalgam fillings.

How can advances in dental technology contribute to eliminating the use of metals in prosthetics, another field of dentistry that relies heavily on the use of metals for prostheses?

Zirconia based CAD/CAM technology is suitable for fabricating fixed prostheses: crowns and bridges. These types of restorations are made of zirconium-oxide and fabricated using computer aided design and computer assisted manufacturing. Zirconium-oxide does not contain any metals or known allergens, and there has been a growing number of evidence that it is completely non-allergenic. In case of removable dentures, which are usually attached to the anchor teeth or dental implants with metal clips, we can replace the metal parts with thermoplastic materials, which are polymer compounds shaped with injection moulding. The material is heated to 220°C and pressed into a mould under high pressure. Depending on the type of restoration, we can create flexible or rigid products that retain their shape. Thermoplastics can be combined with other dental materials and they perfectly fit the biological environment. Restorations made of zirconium oxide, thermoplastics or other materials combined with them can have further advantages. These materials possess excellent mechanical properties, therefore, they are durable and safe. Moreover, the aesthetics of these materials is far better than that of conventional metal-based restorations. These materials can be coloured and the restorations will look like natural teeth, which creates outstandingly harmonic appearance. Zirconia and thermoplastic restorations are comfortable and invisible, which can increase your self-confidence and self-esteem. They are easy to use and clean. It is well worth learning about your treatment options before choosing a restoration. If you would like to know more about modern, metal-free solutions, contact us.
