BACKGROUND: Primary stability of implants is the key factor to the success of implantation, and improving primary stability can raise the rate of successful implantation when bone quality is poor in implant region. OBJECTIVE: Through the establishment of the cancellous bone model to simulate the clinical dental implant surgery, to measure the primary stability of the implant so as to assess the bone extrusion operation effect as compared with the traditional hole prepared surgery. METHODS: Bone segments from the crest of scapular spine of fresh pigs were made into cuboid bone blocks (n=12) of 10 mm×10 mm×10 mm. After fixation, bone extrusion operation and traditional hole prepared surgery were performed to implant BEGO implants with the same specifications and the same type. Primary stability of implants was recorded, and t test was performed. RESULTS AND CONCLUSION: Compared with the traditional hole prepared surgery, a better primary stability for the implant was obtained following bone extrusion operation (P < 0.05), indicating that bone extrusion operation is better for primary stability of implants.
