摘要
目的:观察分析奥邦骨修复材料在下颌阻生第三磨牙拔除同期行引导骨组织再生术(guided bone regeneration,GBR)中的临床疗效。方法:将40例下颌第三磨牙阻生患者随机分为GBR组和对照组(各20例)。GBR组在拔牙后使用奥邦骨修复材料行引导骨组织再生术,对照组常规处理拔牙创后仅严密缝合。术后6个月分别记录两组拔牙区域骨密度,第二磨牙的远中牙槽嵴高度变化及冷热刺激痛度。结果:骨密度(Hu)GBR组(137.35±8.82)高于对照组(109.10±11.40);第二磨牙远中牙槽嵴高度值变化(H)GBR组(4.56±1.43)mm高于对照组(0.93±0.83)mm;术后6个月第二磨牙冷热刺激痛度视觉模拟评分值(visual analogue score,VAS)(0.36±0.31)小于对照组(2.00±1.15),差异均有统计学意义(P<0.01)。结论:奥邦骨修复材料在下颌阻生第三磨牙拔除后同期行GBR中疗效显著。
Objective:To observe the effects of using Osteobone materials of guided bone regeneration(GBR) in the extraction of mandibular third molar.Methods:Forty patients with impacted mandibular third molars were randomly divided into GBR group and control group(20 patients each group).GBR techniques with Osteobone was received in GBR group after extraction,and tight suture were received in control group.The tooth extraction area bone density(Hu),the change of distal alveolar ridge of second molar(H)and the degree of cold and heat stimulate pain(CHSP)were recorded after six months.Results:The Hu in GBR group was(137.35±8.82)while that in the control group was(109.10±11.40)(P<0.01).The H in GBR group was(4.56±1.43)mm while that in the control group was(0.93±0.83)mm(P<0.01).The CHSP in GBR group was(0.36±0.31)while that in the control group was(2.00±1.15)(P<0.01).Conclusion:The effects of using Osteobone materials of GBR in the treatment of impacted mandibular third molar alveolar after extraction is significant.
