【摘要】：目的:對(duì)紫外線光能化影響下的SLA(Sandblasted,Large-grit and acid-etched,大顆粒噴砂酸蝕)表面種植體骨結(jié)合能力進(jìn)行研究,使用共振頻率分析(Resonance Frequency Analysis,RFA)法分析紫外線光能化SLA表面種植體骨結(jié)合穩(wěn)定系數(shù)(Implant Stability Quotients,ISQ)的變化趨勢(shì)。方法:將32名在山西醫(yī)科大學(xué)口腔醫(yī)院種植科就診的下頜后牙區(qū)個(gè)別牙缺失患者選為本文研究樣本(就診時(shí)間:2016年6-12月),共50顆SLA表面種植體,后牙區(qū)被植入24顆經(jīng)紫外線照射的SLA表面種植體(實(shí)驗(yàn)組)和26顆未經(jīng)紫外線照射的SLA表面種植體(對(duì)照組),將術(shù)后即刻、2周,4周、6周、8周、12周,六個(gè)時(shí)間點(diǎn)的種植體的穩(wěn)定性采用OsstellTMISQ共振頻率分析儀進(jìn)行對(duì)比分析,并對(duì)各種植體近中向ISQ值、遠(yuǎn)中向ISQ值、頰側(cè)ISQ值及舌側(cè)ISQ值進(jìn)行連續(xù)監(jiān)測(cè),取算數(shù)平均值,在SPSS18.0軟件基礎(chǔ)上采用統(tǒng)計(jì)學(xué)分析策略來(lái)進(jìn)行分析對(duì)比兩組數(shù)據(jù)的差異。結(jié)果:50顆種植體在植入時(shí)都取得了良好的初期穩(wěn)定性,且在術(shù)后12周,種植體的留存率全部達(dá)到百分之百。實(shí)驗(yàn)組種植術(shù)后即刻,ISQ平均值為68.25±3.09,并在術(shù)后第2周下降至最低,隨后出現(xiàn)逐漸上升。對(duì)照組種植術(shù)后即刻,ISQ平均值為68.88±3.66,術(shù)后呈現(xiàn)下降趨勢(shì)且在術(shù)后第4周下降至谷底,隨后出現(xiàn)逐漸上升。對(duì)比兩組ISQ值,術(shù)后即刻差異無(wú)統(tǒng)計(jì)學(xué)意義(p0.05),而在術(shù)后的第2周,4周、6周、8周、12周統(tǒng)計(jì)學(xué)差異顯著有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:紫外線光能化SLA表面種植體可恢復(fù)種植體生物活性、加快種植體-骨結(jié)合速度、縮短愈合時(shí)間,體現(xiàn)出更高的臨床穩(wěn)定性,具有可靠的臨床指導(dǎo)意義。
[Abstract]:Objective: to study the bone-binding ability of large scale grit and acid-etched surface implants under the influence of ultraviolet light (UV). Resonance frequency analysis (RFA) method was used to analyze the change trend of Implant Stability Quotients-ISQ (Implant Stability Quotients-ISQs) on the surface implants of ultraviolet photovoltaic SLA. Methods: 32 patients with mandibular posterior dentition from the Department of Implant, Department of Stomatology, Shanxi Medical University were selected. Individual dental defect patients were selected as samples in this study (visit time: June-December 2016, 50 SLA surface implants). Twenty-four SLA surface implants (experimental group) and 26 SLA surface implants without ultraviolet irradiation were implanted in the posterior tooth region (control group). The stability of implants at six time points was analyzed by OsstellTMISQ resonance frequency analyzer. The values of ISQ, ISQ, ISQ and ISQ were continuously monitored. Based on SPSS18.0 software, statistical analysis strategy was used to analyze and compare the differences between the two groups of data. Results all of the 50 implants achieved good initial stability at the time of implantation and 12 weeks after operation. The retention rate of implants was 100%. The mean ISQ of the experimental group was 68.25 鹵3.09 immediately after implantation, and decreased to the lowest at the second week after implantation. In the control group, the mean value of ISQ was 68.88 鹵3.66 immediately after implantation, which showed a downward trend and decreased to the trough at the 4th week after implantation, and then increased gradually. The ISQ values of the two groups were compared. There was no significant difference between the two groups immediately after operation (P 0.05), but there was significant difference in the second week, the second week, the 6th week, the 8th week and the 12th week after the operation. Conclusion: the surface implant of UV photoenergy SLA can recover the bioactivity of the implant. Accelerating the speed of implant-bone bonding, shortening the healing time, reflecting higher clinical stability, has reliable clinical significance.
