everStick复合树脂高强纤维材料修复前牙过小缺失间隙

ever Stick Fibre reinforced composites for too small anterior edentulous space restoration

背景:利用ever Stick复合树脂高强纤维材料制作的纤维增强复合树脂黏结桥是近年发展起来的一种微创伤固定修复技术,因其备牙量少、黏结成功率高、美观效果好、机械性能强、易于口内修理等优点,受到患者和临床医生的一致好评。目的:探讨ever Stick复合树脂高强纤维材料用于修复前牙过小缺牙间隙的优势。方法:选择上颌侧切牙缺失且缺失间隙较小的患者23例,采用芬兰Stick Tech公司生产的ever Stick复合树脂高强纤维制作黏结桥,修复过小缺牙间隙。结果与结论:采用ever Stick复合树脂高强纤维制作成黏结桥,修复前牙过小缺牙间隙时,可避免固定义齿对邻牙牙体制备时的磨耗,也避免了传统活动义齿显现卡环不美观及舒适度差等情况的发生。经6-30个月的临床随访观察,23例复诊患者的黏结桥修复体均无松动、无脱黏、折裂和过度磨耗,无继发龋,修复体边缘无明显染色,黏结界面良好,色泽稳定,美观效果好。患者对此种材料完成的修复非常满意。结果表明复合树脂高强纤维修复前牙过小缺失间隙具有抗磨性能良好,机械强度高,色泽稳定,对基牙损伤小,美观效果好的优势。

BACKGROUND：The fiber-reinforced composite resin adhesion fixed bridge produced by everStick fibre reinforced composites is a kind of minimaly invasive fixed prosthesis technology in recent years, which is wel thought of patients and clinicians because of its smal tooth preparation, high success rate of bonding, good esthetic effects, strong mechanical properties and easy to intraoral repair. OBJECTIVE：To investigate the advantage of everStick fibre reinforced composites on too smal anterior edentulous space restoration. METHODS：A total of 23 patients with maxilary lateral incisor missing and with smal edentulous space were colected and renovated with everStick fibre reinforced composites produced by StickTech in Finland. RESULTS AND CONCLUSION：everStick fibre reinforced composites for repair of too smal anterior edentulous space with adhesion fixed bridge could not only avoid the overclosed occlusion on adjacent teeth like fixed denture, but also avoid the usage of clasp and uncomfortableness such as removable denture. During the folow-up of 6-30 months, 23 patients had no signs of loosening, debonding, fracture, excessive wear, secondary caries, margin dying of restoration and exhibited good margins and composite luting-cement interface, unchanged color, good esthetic effects. The patients were very satisfied with the restoration. The results indicate that everStick fibre reinforced composites for restoration of too smal anterior edentulous space can achieve good abrasion resistance and high mechanical strength, unchanged color, have little damage to abutment and have good esthetic effects.
