Fixed prostheses are dental replacements which replace one or more missing teeth. There are several types of fixed prostheses such as crowns, bridges or implants. Crowns replace the dental crown of one tooth and cover the dental structure which used to support the natural crown. Bridges replace one or more teeth by permanently connecting teeth or implants with the toothless area. When more than two thirds of teeth are missing it is necessary to perform grafting which is cemented in root canals and which replaces the tooth structure necessary for crown fitting. There are different materials which are used to make crowns and bridges. Modern dentistry has developed many materials with fantastic aesthetic characteristics, such as all-ceramics and zirconia ceramics. All-ceramics or E-max is a material which imitates the natural tooth, it is translucent and currently the most aesthetic material in dentistry. Zirconia is a biocompatible and very hard material, suitable for production of aesthetic bridges in front and back region and superstructures on implants. Apart from them, there is of course metal ceramics whose main advantage is its price. During the production of crowns and bridges, the teeth are covered and protected by temporary crowns. They are most often made of composites and acrylates, and they enable chewing, speech and function before the fixed prosthesis is finished.


Mobile prosthetics

Mobile prosthesis is any prosthesis which the patient can remove by himself, which replaces the missing teeth and abuts against soft and hard oral structures. Advantages of mobile prostheses are their price and simplicity of their making. They are made in situations when the number and arrangement of teeth don’t allow the burdening of other teeth with a fixed construction, or when there are no teeth or bones for implant placement at all. Mobile prostheses can be total or partial. Total prostheses can be anchored on implants. The fitting of 2-4 implants to which the prosthesis is connected significantly improves retention and stabilization of the prosthesis in the mouth, which is extremely important for lower prostheses.
