[目的]研究牙种植修复技术在有牙缺失的慢性牙周炎患者中的临床应用效果.[方法]选取从2012年5月至2013年6月在本院收治的有牙缺失等需种植牙的牙周炎患者52例作为观察组,选择同时期进行牙种植修复治疗的牙周健康者50例作为对照组.两组均采用相同的牙种植修复技术进行治疗.观察比较两种患者种植修复后半年、1年、3年的种植成功率.分别记录比较其种植体周围龈沟液量(PISF)、改良菌斑指数(mPLI)、改良龈沟出血指数(mSBI)、探诊深度(PPD)及附着丧失(AL)等治疗.[结果]观察组半年、1年的成功率略低于对照组,但无明显差异;但3年后观察组留存率明显低于对照组(P<0.05)观察组种植体PISF、mSBI、PPD、AL明显高于对照组;mPLI明显低于对照组(P<0.05).[结论]对于慢性牙周炎患者采用牙种植修复技术的短期疗效良好,远期疗效则欠佳,可能与慢性牙周炎与种植体周围炎具有关联性有关.“,”[Objective]To study the the clinical effect of dental implant repair in patients with chronic periodontitis.[Methods]52 patients with chronic periodontitis were selected from May 2012 to June 2013 in our hospital as the observation group,50 patients with periodontal health were selected as control group.The two groups were treated with the same dental implant repair technique.The successful rate of planting in the six months,1 years and 3 years after implantation was observed and compared between the two patients.The volume of gingival crevicular fluid (PISF),the improved plaque index (mPLI),modified sulcus bleeding index (mSBI),probing pocket depth(PPD) and the attachment loss (AL) were recorded and compared.[Results]The success rate of the observation group in the half year and 1 year was slightly lower than that in the control group,but there was no significant difference;But retention rate of observation group was significantly lower than the control group after 3 years (P<0.05);Volume of pri-implant sulcular fluid PISF,mSBI,PPD,AL of the observation group was significantly higher than the control group;modified plaque index (mPLI) was significantly lower in the control group (P<0.05).[Conclusion]For chronic periodontitis patients,the short-term curative effect of dental implant repair technique is good,but the long-term curative effect is poor.It may be associated with chronic periodontitis and peri implant inflammation.
