Tooth filling - hard fillings

Hard fillings

Hard fillings are made of materials such as gold alloys, ceramics or, in rare cases, plastic. As so-called "filler fillings" (inlays or onlays), they are produced accurately after grinding and an exact impression of the tooth in a dental laboratory. The finished filling is then used by the dentist. They are characterized by a much longer durability than plastic fillings and fit snugly into the denture. Depending on the material, the following hard fillings differ:

gold inlay

Gold is very well tolerated by the body and has a high durability. A study by the University of Cologne, in the Center for Dental, Oral and Maxillofacial Surgery, shows that after ten years, more than 90 percent of inlays without post-treatment are still in place. Since pure gold can not withstand the chewing pressure, alloys with platinum, palladium, silver or copper are used for dental fillings. Gold casting fillings can also supply large defects. Gold inlays are attached with a special cement, which gives the tooth back its original strength. Gold fillings are a very high-quality dental care and are mainly used in the "molars". In the anterior region you will increasingly be replaced by aesthetic ceramic inlays.

ceramic inlay

A ceramic inlay is made of a ceramic mass in the dental laboratory and "stuck" by the dentist in the tooth under complete draining. By bonding the residual tooth substance is stabilized. From an aesthetic point of view, ceramic inlays meet the highest demands. Whether glass ceramic, oxide or zirconium oxide ceramic - all are tooth-colored, translucent and thus invisible as a filling. The inlay can be adapted exactly to the tooth and convinces also in the points durability and compatibility. The use is very complex and associated with high costs.

Plastic inlay

Although plastic inlays combine function and aesthetics with a low price, due to the soft plastic material, they have only a short life. Thus, they are not suitable as permanent fillings and serve only as a time-limited alternative.

Galvanoinlay

Galvanoinlays are a special combination of gold and ceramic inlay that are rarely used. In the dental laboratory, gold is applied as a thin layer on a model of the drilled hole. This gold substructure is then veneered ceramic. Use and attachment is similar to the gold inlay. Which filling represents the best alternative for which defect can only be clarified after detailed diagnosis and consultation with the treating dentist. Depending on size and location, each method can have both advantages and disadvantages.
