What Are The Functions Of Porcelain Crown?
Porcelain crowns are used to completely cover the damaged tooth. They can be used to improve the image, shape or alignment as well as strengthen the damaged tooth. In addition, it can be placed on the implant to provide a tooth-like shape and structure to provide function. Porcelain crowns can be produced in the color of the teeth. It was formerly often applied to porcelain crowns with metal substructures to ensure their strength. However, today, empress porcelains or laminates that reflect light better in the anterior regions and zirconia supported porcelains in the posterior teeth are applied more frequently. With the protocols between the dentist and the patient, porcelain crowns with a suitable infrastructure can be preferred according to the condition of the tooth.
Why Is A Bridge Built?
If there is one or more missing teeth in the mouth, a bridge can be made.

They fill the gap where there is no tooth. They are used by attaching them to natural teeth or implants around the empty space. Teeth, called support, act as stabilizers for bridges. The tooth placed to fill the gap is placed by attaching to the support crowns. As with the crown, different materials can be chosen within the bridge. These can be produced in the natural color of the teeth.
What Happens When Dentures Are Not Made To Replace Missing Teeth?
If missing teeth are not made, the person's adjacent teeth begin to move towards the opposing tooth extraction space in the other jaw. For this reason, bad tooth closure in the mouth results in caries and tooth loss. When tooth loss occurs for some reason, it moves towards the space created by the loss of adjacent teeth. Therefore, gum problems in the adjacent teeth, bone loss due to the movement of the teeth into the cavity, deterioration in dental aesthetics and changes in chewing force occur. In cases where this gap in the mouth is not restored with an implant or bridge for a long time, tooth loss occurs. Other problems that occur if a prosthesis is not made with a missing tooth are digestive disorders and discomforts experienced with the lack of chewing. Depending on the position of the lost tooth, speech disorder and aesthetic problems may come to the fore.

These factors, in addition to functional disorders, cause a decrease in the sense of self-confidence in people. Over time, different forms of wear occur on the teeth due to grinding of teeth for various reasons during eating, chewing function, swallowing and at night. In addition, some parts of the teeth may break as a result of caries and accidents. In these cases, dental structures can be replaced with prostheses called crowns or bridges.
Applications Used In The Infrastructure Of Porcelain Crowns
Precious metal alloy applications
In this type of prosthesis, precious metal alloys containing gold are used. Aesthetics in the upper structure is provided by porcelain. These are special mixtures used in the field of dentistry. Among the materials used in dentistry, gold is one of the materials that provides the most harmony between teeth and gums. For this reason, applications made with these give healthier results. In addition, zirconium is the most applied metal today and the best supporting porcelain.Standard metal alloy applications
