title: Effect of electromagnetic field on bone regeneration around dental implants after immediate placement in the dog mandible: a pilot study.
abstract: BACKGROUND
  Accelerating bone healing around dental implants can reduce the long-term period between the insertion of implants and functional rehabilitation.
  
  
  OBJECTIVE
  This in vivo study evaluated the effect of a constant electromagnetic field (CEF) on bone healing around dental implants in dogs.
  
  
  METHODS
  Eight dental implants were placed immediately after extraction of the first pre-molar and molar teeth on the mandible of two male dogs and divided into experimental (CEF) and control groups. A CEF at magnetic intensity of 0.8 mT with a pulse width of 25 μs and frequency of 1.5 MHz was applied on the implants for 20 min per day for 2 weeks.
  
  
  CONCLUSIONS
  After qualitative histological analysis, a small quantity of newly formed bone was observed in the gap between the implant surface and alveolar bone in both groups.
