Notes:
To evaluate the effects of progressive loading on implants placed into extraction sockets. 4beagle dogs were extracted bilateral 3rd, 4th and 2nd premolar and immediately inserted the implantat first surgery (0d), 14d and 21d. Using the newly developed vertical occlusion loading system,progressive loading procedures were taken 24h after insertion. The vertical bone loss (VBL) andbone-to-implant contact ratio (BIC) was measured by image analysis software and analyzed using thepaired student t test. After 28d period of healing, each animal was sacrificed and the samples wereevaluated by scanning electron microscopy (SEM). The mean vertical bone loss in control groupswas larger than that of the experimental groups at 14, 21 and 28 day (P〈0.05). SEM showed that themineralization rate of experimental groups was faster than the control groups. The bone-implantcontact ratios in experimental groups were more than that in the control groups. The differences werestatistically significant (P〈0.05). Compared with non-loading implant, progressive loading canpromote osseointegration and decrease vertical bone loss. Progressive loading of implants placed intoextraction sockets can be performed without interfering with the osseointegration process
