根尖保留联合引导骨组织再生在颌骨囊肿术中的应用研究

Application study of apical preservation combined with guided bone regeneration in jaw cyst surgery

目的:探讨颌骨囊肿术中采用根尖刮治保留根尖联合应用Bio-oss骨粉/海奥人工生物膜的临床疗效。方法:选取颌骨囊肿病人55例,分为2组,A组(15例)术中行根尖周刮治术保留根尖,用骨粉覆盖牙根暴露于颌骨缺损的部分,并应用生物膜覆盖;B组(40例)行单纯囊肿摘除术+根尖切除术。所有病人术后均随访12个月以上,比较2组病人术前和术后颌骨囊肿累及牙功能恢复、颌骨缺损骨再生及改建情况。结果:A组术后囊肿累及牙恢复正常功能优于B组(P﹤0.01),A组根尖植骨区成骨效果优于自体愈合区。结论:颌骨囊肿摘除术中保留根尖联合引导骨再生术疗效较好,效果可靠。

Objective:To explore the clinical effects of periapical curettage preservation combined with Bio-oss bone meal/Haiao artificial biomembrane in jaw cyst surgery. Methods:Fifty-five patients with jaw cyst were divided into the group A(15 cases) and group B(40 cases).The group A was treated with the periapical curettage preserving the root tip,bone meal covering the lack of part of the root exposed to jaw and biofilm covering.The group B was treated with simple cyst excision combined with apicoectomy.All patients were followed up for more than 12 months.The recovery of tooth function,bone regeneration and reconstruction of jaw defects between two groups before and after operation were compared. Results:After operation,the normal function recovery in cyst involved teeth in group A was faster than that in group B( P <0.01).The osteogenic effect in bone graft area in group A was better than that in autogenous healing area. Conclusions:The efficacy of apical preservation combined with guiding bone regeneration in jaw cyst excision is good and reliable.
