Denture teeth significantly impact the accuracy of processed denture bases across all tested methods. However, the compression molding technique showed accuracy differences only in denture bases without teeth.

Area of Science:

  • Dental Materials Science
  • Biomaterials Engineering
  • Prosthodontics

Background:

  • Accurate denture fabrication is crucial for patient comfort and function.
  • The influence of denture teeth on the dimensional accuracy of denture bases requires further investigation.
  • Understanding processing method variations is key to optimizing denture base quality.

Purpose of the Study:

  • To evaluate the effect of denture teeth on the accuracy of denture bases processed by three different methods.
  • To compare the accuracy of compression molding, injection pressing, and vacuum-assisted resin pouring techniques.
  • To identify which processing methods are most affected by the presence or absence of denture teeth.

Main Methods:

  • Utilized the Michigan Computer Graphics Coordinate Measuring System for precise measurements.

  • Processed denture bases using three distinct techniques: compression molding, injection pressing, and vacuum-assisted resin pouring.
  • Assessed dimensional accuracy with and without the inclusion of denture teeth for each processing method.

    • Main Results:

    • The presence of denture teeth was found to influence the accuracy of processed denture bases across all three techniques.
    • Compression molding showed significant accuracy differences in denture bases fabricated without teeth.
    • Injection pressing and vacuum-assisted resin pouring techniques did not exhibit significant accuracy differences related to the presence of teeth.

    Conclusions:

    • Denture teeth presence is a critical factor affecting denture base accuracy, varying by processing method.
    • Compression molding is more susceptible to accuracy deviations when teeth are absent.
    • Injection pressing and resin pouring offer greater dimensional stability irrespective of denture teeth presence.
