中文摘要 | 目的:應用齒槽骨撐開緊壓術式來撐開齒槽骨並增加骨緻密度的概念,將此術式施用在下顎後牙區,並利用共振頻率來觀察比較以齒槽骨撐開緊壓術式和傳統擴大方式植入下顎後牙區之植體其12週內穩定度的變化。 材料與方法:本實驗至目前為止,總共有22位病患(骨質條件均為D2-D3),36支植體(ITI Strauman® SLA)參與並完成觀察紀錄。其中22支植體,由於骨脊寬度不足(比理想寬度少2-3mm),所以利用齒槽骨撐開緊壓術式植入(骨鑿組)。另外14支植體由於骨脊條件較接近理想寬度,則利用傳統擴大方式植入植體(傳統組)。植入植體後,分別於術後第0、1、2、3、4、6、8、10、12週以共振頻率分析儀測量植體穩定度值,並紀錄兩組穩定度的變化。統計方式是利用SAS軟體以無母數分析法比較骨鑿組及傳統組在0-12週穩定度的變化,和比較骨鑿組或傳統組第12週之穩定度和其餘檢測週有無差異。 結果:使用齒槽骨緊壓術植入之植體和傳統擴大術式相比,12週內穩定度變化除了第4週及第6週兩組有統計差異(P < 0.05),其餘檢測週,兩組均無統計差異(P > 0.05)。個別組而言,與前一週之紀錄比較,骨鑿組在第3週,傳統組在第3、4週分別探得穩定度下降之表徵,但骨鑿組穩定度下降的幅度較傳統組小。此外,兩組整體穩定度持續上升之演化,均需待至第10週之後才趨於平緩,且與第12週之穩定度無顯著差異。 結論:臨床上在下顎後牙區水平寬度窄於預期植牙寬度的區域進行植牙,合併施予齒槽骨撐開緊壓術式可達到與傳統術式相似的植體穩定度變化,甚至有助於骨整合加速進行之趨勢。 |
英文摘要 | 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 stability of studied implants, either installed by osteotome technique or by conventional technique, was monitored in an observing period of 12 weeks. Materials and methods: There 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、1st、2nd、3rd、4th、6th、8th、10th、12th 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 10 th week in osteotome group and 12 th 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. |
