Influence of Osseodensification Implant Site Preparation Method on the Resonance Frequency Analysis & Insertion Torque Values for Dental Implants An Experimental Study in Dogs

Abstract

The present study was conducted to compare between the effect of osseodensifing drills and extraction drills on the primary and secondary stability of implant fixtures by using peak insertion torque and resonance frequency analysis as methods of measurement. The study was conducted on four mature mongrel dogs of comparable weight (10 to 15 Kg) with age range from nine months to one year. The dogs were kept in the animal house of the faculty of veterinary medicine at Cairo University for 6 months. The Dogs were kept in cages each included two dogs. Dogs were fed on a soft protein-rich diet during the study and were kept in well-ventilated rooms. Antibiotics were administrated preoperative and postoperative in a dose 1mg /kg of ceftriaxone in addition to analgesics, for pain control, in 10mg/ kg. A total of four dogs were included in this study and were numbering as sample A, B, C and D. Each dog jaw was splinted so that it included two implants on each side that had been placed with different implant site preparation methods. Control side, the left side in each dog, two implants were placed with the cutting implant site preparation drills supplied by the implant manufacturer, while the study side, the right side, included two implants placed with the Osseodensification implant site preparation drills (Densah drills). Implant insertion torque value (N/cm) recorded during implant placement by using a surgical motor with torque control and an integrated
