Introduction to the use of dental PMMA

Dental PMMA (polymethyl methacrylate) has many uses in the dental field, mainly including the following:

1.Denture base material: PMMA is one of the most commonly used denture base materials. Because of its good biocompatibility, processing performance and aesthetics, it is widely used in the production of movable denture base. Patients can remove and put on their own dentures for daily cleaning and care.

2.Temporary restorations: During fixed tooth restorations, such as before making porcelain or full porcelain teeth, the dentist may use PMMA to make temporary restorations for the patient to use until the formal restoration is completed.

3.Dental guides and models: PMMA can be used to make dental surgical guides or models to help dentists perform precise surgical planning and operations.

4.Teeth whitening trays: PMMA is also a commonly used material when making teeth whitening trays, as it can be flexibly shaped according to the shape of the patient's mouth and has a high level of comfort.

5.Orthodontic retainers: In orthodontic treatment, PMMA can be used to make transparent orthodontic retainers to help patients keep their teeth in place after orthodontic treatment.

6.Filling material: Although not common, in some cases PMMA can also be used as a filling material for teeth, especially in the anterior tooth area, because of its good aesthetic appearance.

Overall, dental PMMA has a wide range of applications in the dental field due to its biocompatibility, aesthetics, ease of processing and durability. However, with the advancement of materials science, more new dental materials have emerged, providing more options for patients and dentists.
