Abstract:
OBJECTIVEThis study simulated clinical implant surgery using squeeze technique by establishing a rational animal model. To measure the morphologic parameters in order to observe the agglutination of the cancellous bone after being compressed. The study wanted to get some favourable support of implant squeeze technique in bone healing and obtaining primary stabilities of implants, so as to provide some reasonable and valid guidance in the application and improvement of implant squeeze technique.
METHODSThe 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 (0, 0.6, 1.2, 2.0 mm), and then inserted the corresponding implants into them. After different healing periods (1, 2, 4, 12 weeks), the mongrel dogs were sacrificed and the hard tissue slices were made and then the morphologic parameters were measured.
RESULTSThe morphologic parameter of the bone tissue shows that after being compressed, the trabecular bone thickness was almost constant, while the trabecular bone number increased, and the trabecular bone spacing decreased, obviously in the 1-week and 2-week groups. The differences went down gradually along with the extend of healing time.
CONCLUSIONThe clinical implant surgery using squeeze technique can improve peri-implant bone density so it is good for obtaining primary stabilities of implants.
