Abstract:
Objective To investigate the effect of implant superstructure with platform switching to the osseointegration of implant-bone interface in immediate loading.Methods The bilateral mandiblular fourth premolars of 5 beagle dogs were extracted,and 3 months later,10 implants were implanted and the abutments were accessed immediately to form immediate loading.Using self-control,the abutment with platform switching was used in the experimental side,and the traditional abutment used in the control side.The experimental animals were sacrificed after 3 months,and non-decalcified implant-bone sections were made.Results A favorable osseointegration of implant-bone interface in 4 animals (8 implants ) was observed except for one failed case.A large number of osteoblasts and different mineralized bone were observed.In experimental side,the bone and implant-neck were nearly in the same level,but the bone around the implant-neck was significantly absorbed in control side.Conclusions Using different superstructure in immediate loading could affect the osseointegration of implant-neck.The platform switching technology is conducive to the keeping of implant-neck bone.
