The study found no significant difference in retention force for self-threading retention pins when dentin holes were drilled with conventional or gear-reduced handpieces. Conventional handpieces are recommended for easier hole preparation.

Area of Science:

  • Dental materials science
  • Biomaterials engineering
  • Restorative dentistry

Background:

  • Self-threading retention pins are used in restorative dentistry to secure prosthetics.
  • The method of preparing the pinhole in dentin can potentially affect pin retention and instrumentation integrity.
  • Evaluating different drilling techniques is crucial for optimizing clinical procedures.

Purpose of the Study:

  • To compare the retention force of self-threading retention pins in dentin when pinholes are prepared using two distinct drilling methods.
  • To assess the incidence of drill fractures associated with each drilling method.

Main Methods:

  • Holes were prepared in dentin using either a conventional slow-speed contra-angle handpiece or a 10-to-1 gear reduction contra-angle handpiece.

  • The force required to remove self-threading retention pins from the prepared holes was measured.
  • The number of broken drills during the hole preparation process was recorded.

    • Main Results:

    • No statistically significant difference was observed in the retention force of pins between the two drilling methods.
    • Two drills fractured during the preparation of over 100 holes, with both fractures occurring when using the gear-reduced handpiece.
    • Both drilling methods proved acceptable for preparing pin sites.

    Conclusions:

    • The choice between a conventional or gear-reduced handpiece for drilling retention pin sites in dentin does not impact pin retention.
    • Conventional slow-speed handpieces are recommended due to their ease of use in creating pinholes.
    • Clinicians can select either method, but the conventional approach offers greater procedural simplicity and potentially reduced risk of instrument fracture.
