目的:将富血小板纤维蛋白(Pl at el et-ri ch fi bri n,PRF)应用于牙槽嵴裂植骨手术,验证其是否能够减少植骨术后的骨吸收。方法:8~12月龄犬8只,以外科手术的方法制备双侧牙槽嵴裂模型,随机于两侧同期植入自体髂骨(对照组)及自体髂骨混...目的:将富血小板纤维蛋白(Pl at el et-ri ch fi bri n,PRF)应用于牙槽嵴裂植骨手术,验证其是否能够减少植骨术后的骨吸收。方法:8~12月龄犬8只,以外科手术的方法制备双侧牙槽嵴裂模型,随机于两侧同期植入自体髂骨(对照组)及自体髂骨混合PRF(实验组)。于术后当日、2个月、4个月时拍摄上颌骨CT,利用三维重建软件测量植骨区体积,计算骨吸收率。结果:术后2个月、4个月时实验组的骨吸收率明显小于对照组,行配对样本的t检验,P<0.01。结论:将PRF加入自体髂骨进行骨移植修复犬的牙槽嵴裂,在术后4个月的时间范围内,可以减少术后的骨吸收。展开更多
