目的比较单根管与多根管铸造桩核冠修复磨牙残冠的临床效果。方法选择140例患者的153颗磨牙残冠,在修复前行完善的根管治疗,其中92颗采用单根管整体铸造桩核冠修复,61颗采用插销式铸造的多根管桩核冠修复。对修复后两年的复查结果进行临床效果评价。结果单根管固位修复体桩核松动1个,其余桩核X线片显示桩核与根管结合紧密,修复效果良好。多根管分体插销式铸造桩核冠无松动。修复的临床效果无显著性差异(P>0.05)。结论采用单根管铸造桩核修复磨牙残冠不仅制作简单,而且与多根管分体桩核修复无显著性差异,同样可取得良好的临床效果。
Objective To compare the clinical effects of single-tube and multi-tube cast-in-post crowns to repair molars. Methods A total of 153 molar residual crowns of 140 patients were selected and the root canal treatment was performed before the repair. Among them, 92 were treated with a single-piece cast-in-place post and core crown restoration, and 61 were cast with multiple bolt-and-socket crowns . The clinical results of two years after the review of the results of revaluation. Results The single-tube retention prosthesis had one loose post and the rest of the post-core X-ray showed a close combination of the post and the root canal. The repair effect was good. Multi-tube split pin casting pile core without loose. There was no significant difference in the clinical effect of repair (P> 0.05). Conclusion The use of a single tube cast post to repair the crown of molars is not only simple to make, but also has no significant difference with the split-core post-core restoration of multiple tubes. It is also possible to obtain a good clinical effect.
