Dental implantology update·1995

Dental implant components show improved machining tolerances and fit. This study evaluated three external hexagonal implant systems, finding closer correlations and reduced rotational misfit, suggesting enhanced manufacturing consistency.

Area of Science:

  • Biomaterials Science
  • Dental Implantology
  • Mechanical Engineering

Background:

  • Dental implant components require precise manufacturing for optimal function and longevity.
  • External hexagonal connections are common in dental implant systems, necessitating accurate component mating.
  • Variations in machining tolerances can affect implant stability and prosthetic outcomes.

Purpose of the Study:

  • To evaluate the machining tolerances and component fit of three external hexagonal dental implant systems.
  • To assess the rotational misfit and torsional strength of implant-abutment connections.
  • To identify trends in manufacturing accuracy and consistency among implant systems.

Main Methods:

  • Measurement of hexagonal flat-to-flat dimensions for implant systems and their corresponding analogs.

  • Quantification of rotational misfit in implant-abutment connections.
  • Determination of torsional strength for various implant-abutment mating configurations.

    • Main Results:

    • Mean implant hexagonal dimensions ranged from 2.685 to 2.700 mm, with strong correlations observed in analog dimensions.
    • Rotational misfit in implant-abutment matings varied between 1.6 and 5.3 degrees.
    • Torsional strength across different matings ranged from 122.7 to 175.8 N-cm.

    Conclusions:

    • The findings indicate a positive trend towards improved tolerances and component accuracy in dental implant manufacturing.
    • Enhanced fidelity and consistency in implant components are suggested by the data.
    • These improvements may lead to more reliable and predictable clinical outcomes in dental implantology.
