Abstract:

Objective To access the clinical survival and marginal bone loss around implant after immediate loading and investigate related factors.
Methods Total of 171 implants were placed in 75 patients, including 110 ITI implants and 61 Osstem SSⅡ implants. All implants were immediately loaded in 24 hours and final prosthetics were placed in 6 months. Radiologic examinations were taken at post-operation, and measured the marginal bone level around implants after 6 months and 12 months.
Results Clinical survival was 100% in ITI implants and 98.4% in Osstem SSⅡ implants. Main marginal bone loss was observed in 6 months after immediate loading. There was no difference in maxilla, but there was significant difference in bone level post-operation and bone resorption in 6 months in mandible between two systems. From 6 to 12 months, the more bone resorption was observed in single crown group. Conclusion The clinical survival is acceptable in immediate loading procedure if
the implant had excellent primary stability and equal occlusion. The marginal bone loss is dependent on the position of polished-rough junction of one-stage implant.
