The process of covering the exterior part of the teeth with porcelain in cases of excessive loss of substance in the teeth is called dental crowns. In some cases where there are cavities due to loss of teeth in the mouth and where implants cannot be applied, the procedure of creating an interconnected structure through the crowning of the teeth adjacent to the cavity is called dental bridging. When a tooth loss occurs due to any reason, the adjacent teeth start to move towards this cavity. As a result, gingival problems occur in the adjacent teeth along with the loss of bones caused by deviating towards this cavity, a deterioration in aesthetic appearance, and changes in the forces of chewing. If the area that remained empty for a long time is not restored with an implant or a bridge, these adjacent teeth may also be lost. For this reason, dental crowns and bridges cover quite a significant part of dentistry practices. There are many types of porcelains used for dental crowns and bridges. While metal-based porcelains, which have been used for many years, provide a good resistance to the functional forces in the mouth, they give a dull appearance due to the lack of light permeability in terms of aesthetics. Instead, zirconium porcelains or reinforced porcelain structures are preferred, especially for the anterior teeth. Dental crowns and bridges are fixed dentures and are not removed from their places after they are fixed in the mouth by the physician. For this reason, dental crowns and bridges should be cleaned very well in order to use the dentures for many years, and the bridges should be cleaned with dental floss as recommended by your physician.
Removable dentures are dentures that can be placed and removed by patients who have a few teeth in their mouths or who are completely toothless. Since these types of dentures move while chewing or talking, it is very difficult for patients to get used to using this type of dentures. Improvements in implant technology in recent years make it possible to make fixed dentures by applying implants to almost every patient. Therefore, the need for removable dentures decreases gradually.
