两种纤维桩短期修复效果的临床观察

目的 观察两种玻璃纤维桩修复系统修复牙齿缺损的短期临床疗效。方法 选择北京宣武中医医院口腔科门诊和北京大学口腔医院特诊科因牙体缺损进行桩核冠修复的符合纳入标准的120例患者，经知情同意后，随机分2组，每组 60例，分别采用 Tenax Fiber White纤维桩与国产 OUYA FIBER纤维桩修复系统修复，修复后 1周与 3个月复诊，检查纤维桩修复的临床效果。结果 Tenax Fiber White纤维桩与OUYA FIBER纤维桩修复1周后，检查纤维桩修复体的总体情况、边缘密合性、边缘着色情况，两组满意率均达到 98%以上；3个月后复查，通过 X线片检查纤维桩的总体情况和基牙情况，以及咀嚼功能恢复情况，两组满意率均达到 96%以上；2组间比较差异无统计学意义（P>0.05）。结论 OUYA FIBER纤维桩与Tenax Fiber White纤维桩在3个月的观察期间的总体疗效相当，值得推广应用，但仍需对其疗效进行长期的临床观察。

Investigation on the short-term clinical application of two types of glass fiber posts

Objective The clinical results of restoring defective teeth with two types of glass fiber prothetic systems is investigated to acquire clinical experience for further application of glass fiber posts with independent intellectual property rights. Methods A total of 120 out-patients with restored defective teeth were selected from the Department of Stomatology, Beijing Xuanwu Hospital of Traditional Chinese Medicine and Peking University School and Hospital of Stomatology and randomly divided into two groups. OUYA FIBER posts and Tenax Fiber White posts were used to restore defective teeth in the experimental group and the control group, respectively. Clinical evaluation was conducted one week and three months post-restoration. Results Both clinical satisfactory rates of OUYA FIBER posts and Tenax Fiber White posts were higher than 98% one week post-restoration and higher than 96% three months post-restoration. No significant differences were observed between the clinical results of restoring defective teeth with the two types of fiber posts. Throughout the healing process, no root canal fracture or marginal staining were observed.
