摘要: 目的: 研究富血小板纤维蛋白(PRF)用于前牙缺失即刻种植的疗效及其对骨吸收的影响。方法: 选取我院2017年5月至2019年5月收治的90例前牙缺失患者为研究对象,抽签随机分为观察组、对照组2组,各45例。对照组植入种植体后进行常规处理;观察组在对照组的基础上于拔除患牙,在种植牙窝中植入PRF。比较两组治疗后临床疗效、美容效果及不良反应;两组患者分别于治疗2、4、8、12个月后来院复查,比较两组在不同时点骨吸收水平。结果: 观察组临床疗效有效率97.78%显著高于对照组82.22%,差异有统计学意义(P<0.05)。两组患者治疗4、8、12个月与治疗2个月对比,骨吸收水平均降低,差异有统计学意义(P<0.05);观察组治疗2、4、8个月后,骨吸收水平显著低于对照组,差异有统计学意义(P<0.05);治疗12个月后两组患者骨吸收水平无差异(P>0.05)。治疗后观察组的牙体色泽、面部情况评分与对照组对比无差异(P>0.05);治疗后观察组牙体外形、整体美观度评分显著高于对照组,差异有统计学意义(P<0.05)。治疗12个月后,观察组不良反应总发生率6.67%显著低于对照组24.4%,差异有统计学意义(P<0.05)。结论: PRF用于前牙缺失即刻种植临床疗效显著,可促进骨组织修复及创口愈合,降低骨吸收,减少治疗后不良反应发生率,增加牙龈软组织及牙体美观度,值得临床推广。

Abstract: Objective: To study the effect of PRF on immediate implant of anterior teeth loss and its effect on bone resorption. Methods: Ninety patients with anterior teeth missing admitted to our hospital from May 2017 to May 2019 were selected as the research objects. They were randomly divided into two groups: observation group and control group, 45 cases in each group. The control group was treated routinely after implantation, while the observation group was treated with PRF after extraction. The clinical efficacy, cosmetic effect and adverse reactions were compared between the two groups. Two groups of patients were reexamined after 2, 4, 8 and 12 months of treatment, and bone resorption levels were compared between the two groups at different time points. Results: The effective rate of the observation group was 97.78%, which was significantly higher than that of the control group(82.22%, P<0.05). The bone resorption level of the two groups decreased after 4, 8, 12 months of treatment compared with 2 months of treatment(P<0.05). After 2, 4 and 8 months of treatment, the bone resorption level in the observation group was significantly lower than that in the control group(P<0.05). There was no difference in bone resorption between the two groups after 12 months of treatment(P>0.05). After treatment, there was no difference in tooth color and facial condition score between the observation group and the control group(P>0.05). After treatment, the scores of dental appearance and overall aesthetics in the observation group were significantly higher than those in the control group(P<0.05). After 12 months of treatment, the total incidence of adverse reactions in the observation group was 6.67%, which was significantly lower than that in the control group(24.4%, P<0.05). Conclusion: PRF can promote bone tissue repair and wound healing, reduce bone resorption, reduce the incidence of adverse reactions after treatment, and improve dental aesthetics. It is worthy of clinical promotion.
