不同粘接剂在纤维桩修复上前牙残冠残根中的临床疗效比较

Comparison of the Clinical Effects of two Types of Adhesive Bonds in the Maxillary Anterior Tooth Restoration of Residual Crowns and Roots with Fiber Post

目的:比较2种不同的纤维桩粘接剂在桩-核-冠修复方法修复前牙残冠残根的临床疗效。方法:对近2年内的78名96例经过完善根管治疗的上前牙残冠、残根的患者,选用2种不同的粘接材料(3M ESPE RelyX Unicem粘接剂和Panavia F粘接剂)对PD(Produits Dentaires SA)纤维桩进行粘接、3M ESPE Kiltek Z350树脂等材料修复,并经过2年的随访观察,评估2种治疗方法的疗效。结果:经过2年的随访调查发现,96例患牙中仅在半年时出现了1例修复体折断(使用Panavia F粘接法),其余95例均未出现纤维桩的松动、脱落,无根折、桩折现象。结论:纤维桩修复残冠、残根是一种操作简便、省时、临床疗效好的修复方法;3Municem和Panavia F粘接剂均可以有效防止纤维桩在修复上前牙残冠、残根中的松动、脱落现象,均是有效的粘接手段。

ABSTRACT Objective： To evaluate the clinical effects of two different types of adhesive bonds （3M ESPE RelyX Unicem adhesive bond and Panavia F adhesive bond） in the maxillary anterior tooth restoration of residual crowns and roots with fiber post. Methods： Root canal treatment was applied in 96 maxillary anterior teeth from 78 patients, which were then randomly divided into two groups. Group 1 ： fiber post restoration with 3M ESPE RelyX Unicem adhesive bond. Group 2： fiber post restoration with Panavia F adhesive bond. Then 3M ESPE Filtek Z350 were used in the defect restoration. All patients were followed up for two years. Results： After two years of follow-up, we found that only one tooth from a patient failed to restore 6 months after repair in the Panavia F adhesive bond group. Other 95 teeth from 77 patients played roles in mastication function, and no loosen teeth and symptoms were found after restoration. Conclusion： Restoration of residual crown and root with fiber post is easy to operate, time-saving and effective. 3M ESPE RelyX Unicem adhesive bond and Panavia F adhesive bond are both effective means in bonding. Key words： Fiber post; Residual crown and root; Adhesive bond; Restoration of maxillary anterior teeth
