What are the advantages of PMMA denture base?

PMMA(polymethyl methacrylate) denture base has significant advantages in dental restoration, and these advantages make it a widely used denture restoration material in clinical practice. The following are the main advantages of PMMA denture base:

1. Transparency and aesthetics

PMMA material has good transparency, its light transmission rate can reach more than 92%, which makes the denture base produced in the visual closer to the natural teeth, can provide excellent aesthetic results.

2. Durability

PMMA material has good durability and toughness, and is not easy to break and wear. This durability ensures that the denture base can withstand prolonged chewing and rubbing, extending the service life of the denture.

3. Stability and adaptability

The PMMA denture base is well compatible with the oral tissue to provide stable support and fixation. It can be tightly integrated with the oral tissue to ensure the stability and comfort of the denture in the mouth. At the same time, PMMA materials are also adaptable and can be customized according to the patient's oral condition to ensure good fit and comfort.

4. Processing performance

PMMA material has good plasticity and processability, which is convenient for doctors to adjust and repair according to the oral condition of patients. This makes it more flexible and efficient when making and repairing denture bases.

5. Biocompatibility

PMMA denture base does not cause irritation or allergic reaction to oral tissue and has good biocompatibility. This ensures the safety and reliability of the denture base in the mouth.

6. Maintenance and maintenance

PMMA denture bases are relatively easy to clean and maintain. Patients can maintain their good function and appearance by regularly cleaning with a dedicated denture cleaner and avoiding cleaning with overheated water or strong acid and alkali solutions.

7. Cost effectiveness

Compared to other denture restoration materials, PMMA materials are relatively affordable, which makes PMMA denture bases a cost-effective restoration option.

8. Antibacterial properties (achieved by modification)

Although the antibacterial performance of pure PMMA is limited, the antibacterial performance of PMMA denture base can be significantly improved by adding antibacterial agents or surface modification, and the risk of oral infection can be reduced.

In summary, PMMA denture bases perform well in terms of transparency, durability, stability, processability, biocompatibility, care and maintenance, and cost effectiveness, which make them widely used in clinical denture restoration materials. At the same time, the modified treatment can further improve its antibacterial properties to meet the needs of different patients.
