title: Self-cutting blades and their influence on primary stability of tapered dental implants in a simulated low-density bone model: a laboratory study.
abstract: OBJECTIVE
  This study tested the hypothesis that there would be differences in primary stability due to the presence of self cutting blades. We investigated the effect of a self-cutting blade implant design on the primary stability of tapered dental implants in a simulated low-density bone model.
  
  
  METHODS
  Implant fixtures with 2 different designs, one with self-cutting blades and the other without self-cutting blades, were fabricated in the same implant system. Insertion torque, resonance frequency analysis, reverse torque, and pull-out and push-in tests were evaluated in grade no. 10 solid rigid polyurethane foam.
  
  
  RESULTS
  All 5 assessments of the group without self-cutting blades were significantly higher than those of the self-cutting group (P < .001).
  
  
  CONCLUSIONS
  The implants without self-cutting blades create a lateral compression with increased contact surface area and consequently improve the primary stability in a simulated low-density bone model.
