CBCT评价CGF+生物骨修复材料促进颌骨囊肿术后骨缺损修复效果评价分析

Evaluation and Analysis of the Effect of CBCT to Evaluate CGF+Bio-Osteoprosthetic Materials to Promote Bone Defect Repair After Jaw Cyst Surgery

目的:探讨锥形束CT(Cone Beam Computed Tomography,CBCT)评价浓缩生长因子(Concentrate Growth Factors,CGF)+生物骨修复材料促进颌骨囊肿术后骨缺损修复效果。方法:选取2022年1月~2023年10月本院收治的80例颌骨囊肿术后骨缺损患者作为研究对象,根据修复方案不同分成对照组40例、观察组40例。对照组给予CGF修复,观察组给予CGF+生物骨修复(Bio-Oss骨粉)。比较两组骨密度灰度值、疼痛程度以及肿胀程度。结果:骨密度灰度值(Hounsfield Unit,HU)水平组间、时间及交互对比有意义(P<0.05)。两组HU值术后1月增高、术后3月下降,且观察组HU值均低于对照组(P<0.05)。视觉模拟评分法(Visual Analogue Scale,VAS)评分水平组间、时间及交互对比有意义(P<0.05)。两组VAS评分术后2d出现上升、术后5d降低,观察组均低于对照组(P<0.05)。观察组术后2d肿胀程度轻于对照组(P<0.05)。结论:在促进颌骨囊肿术后骨缺损修复中,经过CBCT评价,CGF联合生物骨修复材料与单独CGF相比,HU值更高,术后疼痛以及肿胀程度均降低,可以促进骨愈合、提高成骨质量、加快恢复颌骨形态。

Objective:To explore evaluation and analysis of the effect of cone beam computed tomography(CBCT)to evaluate concentrate growth factors(CGF)+bioosteoprosthetic materials to promote bone defect repair after jaw cyst surgery.Methods:80 patients with postoperative bone defects in jaw cysts admitted to our hospital from January 2022 to October 2023 were selected as the study subjects,and were divided into 40 cases in the control group and 40 cases in the observation group according to the different repair schemes.CGF repair was given to the control group and CGF+biologic bone repair(Bio-Oss bone meal)was given to the observation group.Bone density gray value,pain level and swelling level were compared between the two groups.Results:The gray value of bone mineral density(Hounsfield Unit,HU)was significant among the horizontal groups,time and interaction(P<0.05).The HU values of the two groups increased 1 month after surgery and decreased 3 months after surgery,and the HU values of the observation group were lower than those of the control group(P<0.05).The comparison of Visual Analogue Scale(VAS)score level,time and interaction was significant(P<0.05).The VAS score of both groups was increased 2 days after surgery and decreased 5 days after surgery,and the observation group was lower than the control group(P<0.05).The 2d swelling degree of the observation group was less than that of the control group(P<0.05).Conclusion:In promoting postoperative bone defect repair of jaw cysts,CGF combined with bio-osteoprosthetic materials showed higher HU values evaluated by CBCT and reduced postoperative pain as well as swelling compared with CGF alone,which can promote bone healing,improve osteogenic quality,and accelerate the restoration of jaw bone morphology.
