Creating a space between the denture base and root cap effectively controls occlusal force distribution. Larger spaces (0.6 mm) significantly reduce force on abutment teeth, protecting them from damage.

Area of Science:

  • Biomaterials Science
  • Dental Prosthetics
  • Biomechanics

Background:

  • The distribution of occlusal forces is critical for the longevity of dental prostheses and supporting structures.
  • A gap between the denture base and root cap can modulate force distribution to abutment teeth and the alveolar ridge.

Purpose of the Study:

  • To investigate the impact of varying space (0 mm, 0.3 mm, 0.6 mm) between the denture base and root cap on occlusal force distribution ratios.

Main Methods:

  • Six adult subjects (38-65 years) with an edentulous maxilla and remaining mandibular teeth participated.
  • An experimental lower denture with an embedded transducer measured vertical forces applied to an experimental tooth.
  • Subjects applied increasing occlusal forces (up to 5 kgf s-1) with varying spaces, and forces were recorded.

Main Results:

  • When force was applied directly above the abutment, the force ratio on the abutment decreased as space increased: 60% (0 mm), 50% (0.3 mm), and 30% (0.6 mm).
  • Applying force 10 mm away from the abutment further reduced the force ratio by 60-80% across all space conditions.

Conclusions:

  • A space between the denture base and root cap is an effective method for controlling occlusal force distribution.
  • Increasing this space significantly reduces the load on abutment teeth, potentially enhancing prosthesis and abutment survival.
