玻璃纤维桩复合树脂核在楔状缺损露髓基牙中的应用

Glass fiber composite resin cores used in wedge-shaped defect dew pulp abutment teeth

目的:观察玻璃纤维桩复合树脂核在楔缺露髓基牙修复中的临床疗效。方法:选取101颗经完善根管治疗的楔缺露髓牙(上颌45颗,下颌56颗),经纤维桩修复后患者经过3、6、12个月随访,观察其临床修复效果。结果:修复后3、6、12个月复查随访发现,上颌前牙11颗,前磨牙27颗,磨牙6颗,下颌前牙15颗,前磨牙33颗,磨牙8颗冠桥无脱落,桩核无脱落及折断,牙齿无折断,X线检查无根折;上颌前牙1颗,桩核脱落,牙齿无折断,X线检查根中1/3折断。修复3、6、12个月效果比较,差异无统计学意义(P>0.05)。结论:玻璃纤维桩复合树脂核在楔缺露髓基牙修复中的3、6、12个月的临床疗效无显著性差异。玻璃纤维桩在牙体缺损修复中具有抗牙折性、美观效果好等优点。

Objective To observe the glass fiber composite resin cores in wedge of pulp abutment clinical curative effect of repair. Methods Select 101 after perfect root canal therapy of wedge dew pulp teeth（maxillary 44,mandible 56）,the fiber pile repair patients after two years after 3,6 and 12 months follow-up,observe its clinical repair effect. Results Repair after 3,6 and 12 months follow-up findings：review of the maxillary anterior teeth 11,27,premolar teeth six,jaw teeth before 15,premolar33,molar eight crown bridge without,pile nuclear free fall off and break,no broken teeth,X-ray rootless fold;Upper front teeth one pile nuclear fall off,no broken teeth,X-ray check a third break in the root.Repair effect of 3,6 and 12 months the differences of no statistical significance（P 0.05）.Conclusion Glass fiber composite resin cores in wedge of pulp abutment repair clinical curative effect of 3,6 and 12 months there was no significant difference.Glass fiber post in tooth defect have fight tooth folding resistance,beautiful effect is good.
