种植修复后慢性牙周炎患者种植体的松动度、SBI 及 PIS 指数的变化水平

目的：探讨种植修复对慢性牙周炎患者的近期疗效。方法60例牙列缺损慢性牙周炎患者共植入75枚种植体，另选择50例植入67枚种植体牙周健康牙列缺损患者作为对照组。比较两组改良龈沟出血指数（mSBI）、牙龈乳头指数（PIS）、改良菌斑指数（mPLI）、牙周探诊深度（PD）；并检测两组种植体周围龈沟液白细胞介素（IL）‐2、IL‐8水平。结果研究组75枚种植体中有2枚自行脱落，种植体松动度0，种植体存留率为97．3％；对照组无种植体脱落，种植体松动度0，种植体存留率为100％，两组种植体存留率比较差异无统计学意义（χ2＝2．737，P＝0．098）。术后6个月研究组 mSBI 、PIS 、mPLI 、PD 与对照组相比差异无统计学意义（P＞0．05）；手术前后研究组龈沟 IL‐2、IL‐8水平均显著高于对照组（P＜0．05）。结论慢性牙周炎患者进行种植修复能够获得满意的近期疗效，且未增加种植体周围炎的风险，但其远期疗效尚待证实。

Implant mobility,SBI and PIS changes in patients with chronic periodontitis after implant treatment

Objective To explore the short‐term effect of chronic periodontitis patients after implant treatment .Methods Selected 60 cases of tooth loss in chronic periodontitis patients as research group ,a total of 75 implants were placed ,and 50 cases of periodontal healthy teeth missing patients as control group ,a total of 67 implants were placed .Compared two groups of modification sulcus bleeding index(mBII) ,papilla index score(PIS) ,modification plaque index(mPLI) and probing depth(PD) 6 months after op‐eration ,and detected implant sulcular fluid IL‐2 ,IL‐8 content in two groups before and after operation .Results Research group 75 implants had 2 off on their own ,implant loosening degrees 0 ,implant survival rate was 97 .3% ;the control group had no implant failure ,implant loosening of implant survival rate was 100% ,two groups of implant survival rate was no significant difference(χ2 =2 .737 ,P= 0 .098) .The mSBI ,PIS ,mPLI ,PD in research group and control group had no statistically significant(P > 0 .05) .Re‐search group sulcular fluid IL‐2 ,IL‐8 content was significantly higher than those in control group before and after the operation (P< 0 .05) .Conclusion The short‐term effect of implant treatment in chronic periodontitis patients is satisfactory ,without increas‐ing the risk of peri‐implantitis ,and worth of clinical promotion .
