摘要
背景:桩核冠修复能够最大限度地保存牙体组织,恢复牙齿功能及外形美观,其中桩核材料的选择是成功修复的关键。目的:对比纤维桩与金属铸造桩修复上颌前磨牙缺损的效果。方法:选择上颌前磨牙缺损患者132例(患牙146颗),其中男54例,女78例,年龄43-67岁,根据患者意愿分组治疗,试验组采用纤维桩修复(n=74),对照组采用金属铸造桩修复(n=58)。治疗后随访12个月评价临床疗效;于治疗前、治疗后1周、治疗后1个月、治疗后12个月,检测两组龈沟液中炎性因子白细胞介素6、白细胞介素8及肿瘤坏死因子α水平。结果与结论:试验组83颗患牙中,发生冠折2例、桩松动2例,治疗成功率为96.4%;对照组63颗患牙中,发生冠折1例、根折4例、桩脱落3例、桩松动2例、根尖周变2例,治疗成功率为81.0%,试验组治疗成功率高于对照组(P<0.05)。两组治疗后白细胞介素6、白细胞介素8及肿瘤坏死因子α水平均较治疗前显著下降(P<0.05),且试验组治疗后各时间点下降幅度明显大于对照组(P<0.05)。表明纤维桩修复上颌前磨牙能够减轻炎症反应,提高治疗成功率,修复效果优于金属铸造桩。
BACKGROUND：Post-core-crown can maintain the dental tissue to the utmost, restore tooth function and beautify the appearance. Post and core material selection is the key to successful tooth repair. OBJECTIVE：To compare the application value of fiber post and metal post in repairing the maxilary premolars. METHODS：Totaly 132 patients with maxilary premolar defects （146 teeth） were enroled, including 54 males and 78 females, aged 43-67 years. According to patient’s wilingness, the patients were divided into testing group （fiber post,n=74） and control group （metal post,n=58）. Al the patients were folowed up for 12 months for clinical evaluation. Levels of interleukin-6, interleukin-8, and tumor necrosis factor α in the gingival crevicular fluid were detected before, at 1 week, 1 month, and 12 months after treatment. RESULTS AND CONCLUSION： Of the 83 affected teeth in the testing group, crown fracture occurred in 2 teeth, post loosening occurred in 2 teeth, and the successful rate was 96.4%. Of the 63 affected teeth in the control group, crown fracture occurred in 1 tooth, root fracture in 4 teeth, post shedding in 3 teeth, periapical change in 2 teeth, and the successful rate was 81.0%. Compared with the control group, the successful rate was higher in the testing group （P has a higher application value than metal post.
