Outstanding Advantages of PMMA in Dental Restoration

PMMA, a classic and widely used polymer material, plays a significant role in dental restorations. Its excellent physical properties, aesthetic appeal, and adaptability to processing make it an ideal choice for denture bases, temporary crowns and bridges, and other dental restoration materials.

1. Versatile Applications

Audental PMMA products cover a wide range of applications, including:

  • Temporary Crowns and Bridges: Provide short- or long-term temporary restoration options that meet functional needs during the transition period while maintaining good aesthetic results.
  • Verification of the bridge on the plaster model/mouth
    Full and Partial Dentures: Used as base materials for dentures, providing comfort and stability.
  • Bite Guards and Therapeutic Splints: Address issues such as night grinding or sports protection needs.
  • Frameworks and Drilling Templates: Suitable for complex restoration designs and implant guides.

This versatility makes Audental PMMA an indispensable material in dental restoration, covering applications from temporary repairs to permanent dentures.

 

2. Outstanding Material Performance

Audental PMMA excels in various performance aspects due to its optimized material formulation:

  • Wear Resistance: The material exhibits outstanding wear resistance, maintaining a smooth surface and stable shape even after prolonged use.
  • Polishing Ability: Audental PMMA has excellent surface finish and can easily achieve a high level of polish, enhancing the aesthetic appeal and comfort of the restoration.
  • Color Stability: It is resistant to discoloration over time, and its aesthetic properties can closely match natural tooth color.

These performance characteristics ensure that Audental PMMA provides durable, reliable performance during wear.

3. Aesthetic Effects: Single and Multi-layer Options for Personalized Needs

Audental PMMA offers a rich variety of color choices, including Clear, Pink, A0, Vita 16 shades, and Bleach 1-4, suitable for various dental restoration requirements:

 

  • Mono PMMA: Suitable for economic restorations or short-term use, meeting basic functional and aesthetic needs.
  • Multilayer PMMA: Features gradual color transitions that mimic natural teeth, particularly ideal for high aesthetic demands in restorations.

The availability of both single-layer and multi-layer options allows for a range of solutions, from budget-friendly to high-end customized restorations, helping clinicians design more targeted solutions for different patients.

4. Stability and Durability

Audental PMMA provides excellent long-term stability:

  • Water Resistance: The material has low water absorption (≤40 μg/mm³), ensuring stable dimensions and performance in the moist oral environment.
  • Low Solubility: The solubility is only ≤7.5 μg/mm³, which prevents material degradation that could affect oral health.
  • Deformation Resistance: Audental PMMA maintains its original shape and function even under high chewing forces and in complex oral environments.

This stability makes it ideal for long-term use in full or partial denture bases, effectively extending the lifespan of restorations.

5. Processing and Ease of Use

Audental PMMA exhibits excellent processing characteristics, making it compatible with modern digital dental design and production:

  • CAD/CAM Compatibility: Can be precisely processed through digital systems, improving the fit and production efficiency of restorations.
  • Ease of Carving and Adjustment: The material demonstrates excellent stability during processing, allowing clinicians to quickly adjust the restoration to match the patient’s oral structure.
  • Superior Polishing Performance: Enables clinicians to achieve a high-gloss finish in a short time, enhancing patient satisfaction.

The ease of processing provided by Audental PMMA saves time during the dental restoration process while ensuring the quality of the final product.

6. Optimized Mechanical Properties

Audental PMMA stands out in mechanical performance:

  • Flexural Strength: Greater than or equal to 50 MPa, meeting the mechanical demands of various oral environments.
  • Elastic Modulus: 2500 MPa, providing both sufficient rigidity and a degree of flexibility to alleviate discomfort during wear.
  • These properties ensure that Audental PMMA performs reliably in areas with high chewing forces or in complex restoration scenarios.

7. Weather Resistance and UV Protection

Audental PMMA materials feature excellent UV resistance and weathering properties. Even with long-term exposure to light and fluctuating temperature and humidity in the oral environment, the material is not prone to aging or discoloration. This ensures the aesthetic and functional longevity of restorations.

8. Clinical Case Support

The clinical cases shown in the images demonstrate that:

  • The material easily combines natural aesthetics with functionality, suitable for everything from single tooth restorations to full dentures.
  • Its exceptional layering effect and aesthetic performance make it particularly outstanding in anterior restorations, providing patients with a more natural smile.
