【摘要】Objective To compare the implants' stability under early loading ( 6 weeks-healing ) with that under delayed loading ( 12 weeks-healing ) to provide ohjective data for choosing the timing of implant restoration in clinics using resonance frequency analysis ( RFA ). Methods 52 Straumann implants were placed into 25 partially or totally edentulous patients. The patients were divided into 2 groups randomly. The test group was loaded at the 6th week after surgery. The control group was loaded at 12th week after surgery.ISQ was tested by RFA on the day of surgery and consecutively at the 1st, 2nd. 4th, 6th, 8th, lOth and 12th week. Results All the 52 implants achieved good primary stability in surgery. The mean ISQ value was 64. 39 ±0. 66 on the day of surgery and dropped to the lowest point at the 4th week after surgery, then got notable increase between 4th and 6th weeks after surgery in the stability curve.There was no statistics difference of mean ISQ value and its changing pattern between different loading time. Conclusions The present study indicated that the healing with early loading of Straumann implant at the 6th week could be predictable. The early loading could be applied in properly planned and well-selected cases.%
