Traditional dental appliances are the most commonly used type of fixed braces. These appliances use brackets made from a variety of materials, such as metal and tooth-colored ceramics, which are attached to individual teeth and connected by a wire arch. Orthodontic elastic bands can also be added to the braces to apply extra pressure to certain teeth. Zinc oxide eugenol has the lowest compressive and tensile strength compared to other coatings, so this coating should be limited to small or non-stressed areas, such as class V cavities. This coating is often used with a high-strength base to provide strength, rigidity and thermal insulation.
Eugenol, zinc oxide, can be used as a coating in deep cavities without damaging the pulp due to its abundant effect on the pulp and its bactericidal properties due to zinc. However, eugenol can interfere with resin-based fillers, causing discoloration and sometimes preventing polymerization, so caution must be taken when using both together. It is also radioopaque, which allows fillings to be visible through X-rays. The harness is a dental appliance fixed to a metal structure and is most often used to correct growth and development problems.

However, dental clinics often report discoloration, hydrolytic degradation and fracture of PMMA appliances, indicating that the properties of PMMA need further improvement. Dental restoration materials are used to replace lost tooth structure, usually due to tooth decay (tooth decay), but also due to tooth wear and dental trauma. While PMMA certainly has many good properties (such as its strength, ease of handling and cost-effectiveness) and has gained popularity for several dental applications, as mentioned above, this material has several deficiencies that do not match the properties of an ideal material for denture bases or other dental applications. Polymethyl methacrylate (PMMA) is commonly used for prosthetic dental applications, including the manufacture of artificial teeth, denture bases, obturators, orthodontic retainers, temporary or temporary crowns and for repairing dental prostheses. Indirect restorations are those in which the tooth or teeth that will receive the restoration are first prepared, then a dental impression is taken and sent to a dental technician who manufactures the restoration according to the dentist's prescription.
