Abstract: Objective This study simulated clinical implant surgery using squeeze technique by establishing a rational animal model. We investigated the X-ray image in order to observe the agglutination of the cancellous bone after being compressed. Methods The cancellous bone in condyles of femur of dog had been chosen as the experimental position, prepared the implant holes using squeeze technique according to different compressing extent, and then insetted the corresponding implants into them. After different healing periods, the dogs were sacrificed and the X-ray images were got and observed. Results The cancellous bone in X-ray image shows apparent eburnation and favourable agglutination after being compressed. The differences grow down gradually along with the extend of healing time. Conclusion The clinical implant surgery using squeeze technique is in favor of obtaining primary stabilities of implants.
