文题释义:
改良型富血小板纤维蛋白(advanced-platelet-rich fibrin,A-PRF):是二代血小板浓缩制品富血小板纤维蛋白(platelet rich fibrin,PRF)的改良版,在PRF的基础上,采用低速延时的方法,得到更为疏松的结构,有利于细胞的增殖和分化。
下颌阻生智齿:下颌智齿又称为下颌第3磨牙,是牙列中最晚萌出的牙齿,位于牙列的最后端,常因萌出位置不足或方向不正而阻生,引发智齿冠周炎或相邻第2磨牙的牙体和牙周疾病,目前国内外有关下颌智齿拔除相邻第2磨牙远中骨修复的报道仍然较少。
摘要
背景
:改良型富血小板纤维蛋白的提取方法已经确定,其组织结构及成分也得到研究。已有动物实验证实改良型富血小板纤维蛋白可以与成骨细胞有协同作用,促进新骨形成。
目的:提取改良型富血小板纤维蛋白,观察改良型富血小板纤维蛋白凝胶对下颌智齿拔除后相邻下颌第2磨牙远中骨缺损修复的影响。
方法:选取安徽医科大学附属安庆医院口腔科的48例单侧下颌第3磨牙近中阻生或水平阻生患者。随机将患者分为改良型富血小板纤维蛋白组和对照组,采用相同方法拔除第3磨牙,清理拔牙窝,改良型富血小板纤维蛋白组同期在第2磨牙远中面放入由患者自体血制成的改良型富血小板纤维蛋白凝胶;对照组拔牙后不放任何材料。治疗后1,2,3,4个月复诊,评估患者相邻下颌第2磨牙牙周情况,包括牙周探诊和影像学分析。治疗后第4个月拍摄全口曲面断层片及锥形术CT。采用SPSS 21.0统计软件对试验数据进行统计分析。
结果与结论:①改良型富血小板纤维蛋白组和对照组在相邻第2磨牙远中牙周探诊深度上没有统计学意义;②治疗后第4个月,改良型富血小板纤维蛋白组骨密度显著高于对照组(P < 0.05),骨获得量显著大于对照组(P < 0.05);③结果说明,改良型富血小板纤维蛋白在下颌智齿拔除后下颌相邻第2磨牙远中骨缺损修复中有良好的促进成骨的作用。

Abstract:

BACKGROUND: Extraction method of modified platelet-rich fibrin has been determined, and its structure and constitutes have been investigated. Animal experiments have shown that modified platelet-rich fibrin can cooperate with osteoblasts to promote osteogenesis.
OBJECTIVE: To extract modified platelet-rich fibrin and to explore the effect of modified platelet-rich fibrin gel on the repair of distal bone defect of adjacent mandibular second molar after extraction of mandibular wisdom tooth.
METHODS: Forty-eight patients with proximal or horizontal obstruction of unilateral mandibular third molar were selected from the Department of Stomatology of Anqing Hospital Affiliated to Anhui Medical University. Patients were randomly divided into modified platelet-rich fibrin group and control group. The third molar was removed and the tooth extraction socket was cleared by the same method. Modified platelet-rich fibrin gel made from the patient’s own blood was put into the distal surface of the second molar in the modified platelet-rich fibrin group at the same time. The control group did not put any materials after tooth extraction. All patients were followed up at 1, 2, 3 and 4 months after surgery to evaluate the periodontal status of adjacent mandibular second molars, including periodontal examination and imaging analysis. Full-oral curved tomography and cone-beam CT were taken at 4 months after surgery. Statistical analysis was conducted on SPSS 21.0 software.
RESULTS AND CONCLUSION: (1) There was no significant difference in the periodontal depth of the adjacent second molars between modified platelet-rich fibrin and control groups. (2) At 4 months after surgery, the bone mineral density and bone yield in the modified platelet-rich fibrin group were significantly higher than those in the control group (both P < 0.05). (3) In summary, modified platelet-rich fibrin can promote osteogenesis of mandibular proximal second molar after mandibular wisdom tooth extraction.
