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。

Abstract:

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 maxillary premolars.
METHODS: Totally 132 patients with maxillary premolar defects (146 teeth) were enrolled, including 54 males and 78 females, aged 43-67 years. According to patient’s willingness, the patients were divided into testing group (fiber post, n=74) and control group (metal post, n=58). All the patients were followed 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 < 0.05). After treatment, the levels of interleukin-6, interleukin-8, and tumor necrosis factor α in the gingival crevicular fluid were all significantly decreased in both two group (P < 0.05), but these levels were significantly lower in the testing group than the control group after treatment (P < 0.05). Overall, the fiber post for repairing maxillary premolars can alleviate inflammatory response and improve the treatment success rate, which has a higher application value than metal post.
