摘要

Purpose: The purpose of this prospective clinical study was to investigate the implant stability of mandibular posterior implants that were evaluated by the resonance frequency analysis. The implant stabi1ity of studied implants, either installed by osteotome technique or by conventional technique, was monitored in an observing period of 12 weeks. Materials and methods: Trhere were 36 implants installed in 22 patients (bone quality: D2-D3), including 22 implants positioned by osteotome technique and 14 fixtures placed by conventional drilling technique in this study. The resonance frequency analysis of the implants were measured by an Osstell mentor and recorded as ISQ values at 0、1(superscript in st)、2(superscript in nd)、3(superscript in rd)、4(superscript in th)、6(superscript in th)、8(superscript in th) 、10(superscript in th)、12(superscript in th) week after implant surgery. All collected ISQ values were analyzed at the end of the study by the Wilcoxon rank sum test with SAS system. Results: Statistic significant differences of implant stability were found at the 4th and 6th week between test and control groups. The stability declined at the 3rd week on osteotome group and at the 4th week on conventional group. However, the amount of regression was less in osteotome group. The plateau of the curves occurred at 10th week in osteotome group and 12th week in control group. Conclusion: Within the limitation of this observation, our results show implant placed with osteotome technique could be applied on mandibular posterior area where the ridge width is less than the planned implant diameter. The healing pattern of osteotome technique, surveyed by Osstell, is similar with the conventional drilling technique. Additionally, there is a trend that osteotome technique may improve the osseointegration of implant.
