Study on angle of immediate loading of immediate implant placement

To investigate the clinical immediate load at an angle after immediate placement of the implant. Select 4 adult dogs; through establishing the angle loading animal experiment model, perform lateral loading on 32 implants respectively at vertical and 0°, 10°, and 20°, with which as a basis for groupi...

description To investigate the clinical immediate load at an angle after immediate placement of the implant. Select 4 adult dogs; through establishing the angle loading animal experiment model, perform lateral loading on 32 implants respectively at vertical and 0°, 10°, and 20°, with which as a basis for grouping, determine the osseointegration index and new bone growth rate; and observe the peri-implant bone remodeling conditions. The 20° group is found with the most obvious bone absorption, and compared with other groups, its osseointegration index and new bone growth rate are statistically significant (P < 0.01); bone remodeling under 0° load stress is the best, with the formation of new bone and the highest bone contact ratio, which is the most reasonable under this the stress distribution compared with other angles. The implant stress distribution at 0° against the occlusal force direction is closer to physiologic optimum stress on the implant bone interface, and it is permitted for the long axis of the immediately implanted and immediately loaded implant to be tilted within about 10° against the load angle.
