超强玻璃纤维夹板在牙周再生性手术中的应用观察

目的:观察超强玻璃纤维夹板在牙周再生性手术中应用的临床效果。方法:选择基础治疗后牙周袋深度≥5 mm伴垂直型骨吸收的前牙慢性牙周炎患者27例，随机分为A组（13例）和B组（14例）。A组直接行植骨术+引导组织再生术，B组在超强玻璃纤维夹板固定后行植骨术+引导组织再生术。记录术前和术后6、12个月所有患牙的临床附着丧失（clinical attachment loss,CAL）和X线片情况。结果:2组术后6、12个月患牙CAL均较术前显著降低（P<0.01），且12个月时，B组患牙CAL明显低于A组（P<0.01）。2组患牙术后6个月和12个月X线片结果差异均无统计学意义（P>0.05）。结论:牙周再生性手术前应用超强玻璃纤维夹板固定术，可促进牙周组织再生，巩固牙周病的治疗效果。

Clinical application of super glass-fiber splint in periodontal regeneration surgery

Objective: To investigate the clinical application effects of the super glass-fiber splint in periodontal regeneration surgery.Methods: Twenty-seven patients with chronic periodontitis of anterior teeth,the periodontal pocket depth of which was more than or equal to 5 mm complicated with vertical bone resorption after basic treatment,were randomly divided into group A(13 cases)and group B(14 cases).The group A were treated with bone graft combined with guided tissue regeneration(GTR),the group B were treated with bone graft combined with GTR after super glass-fiber splint fixation.The clinical attachment loss(CAL) and result of X-ray in all disease teeth were recorded before operation and after 6 and 12 months of operation.Results: Compared with that in two groups before operation,the CAL of the disease teeth decreased significantly after 6 and 12 months of operation(P<0.01),the CAL of the disease teeth decreased significantly after 6 and 12 months of operation(P<0.01),the CAL of the disease teeth in group B was significantly higher than that in A group( P<0.01).The differences of the results of X-ray between two groups were not statistically significant after 6 and 12 months of operation(P>0.05).Conclusions: The super glass-fiber splint fixation before periodontal regeneration surgery can effectively promote the regeneration of periodontal tissue and consolidate the treatment effect of periodontal disease.
