项目摘要
The purpose of this study was to evaluate the clinical performance of fixed prosthodontic restorations. The resin-bonded fixed partial dentures(RBFPDs)and resin veneer restorations made from a silver-palladium-copper-gold alloy were selected and assessed. Regarding RBFPDs, the retention of 81 RBFPDs inserted during the 1987 to 2002 using a thione primer as the metal conditioner(Metaltite or V-Primer)and an adhesive resin (Super-Bond C&B) was clinically evaluated. Two levels of survival were defined : (1)complete survival(no debonding) and (2)functional survival(including loss of retention on one occasion with rebonding of the original RBFPD). All data were obtained from clinical examinations, and missing data were censored at the date of the last available information. Mean survival periods were determined using the Kaplan-Meier procedure. Of the 81 RBFPDs, five restorations failed, one of which could be rebonded. The observation duration and corresponding survival ratio for complete survival were 165 months and 43.9%, and those for functional survival were 178 months and 87.7%, respectively. In relation to the missing tooth/teeth, the location and the number of missing teeth and abutment teeth, and the type of abutment preparation, these factors had no statistical affect on longevity, although the survival curves showed different tendencies. Regarding the resin veneer restorations assessed demonstrated clinical success after one-year evaluation period. The results indicate that resin bonding system including noble metal conditioner is clinically reliable for longevity, of fixed prosthodontic restorations made from a silver-palladium-copper-gold alloy.
本研究的目的是评价固定义齿修复的临床效果。对由银-钯-铜-金合金制成的树脂粘结固定义齿和树脂贴面修复体进行了选择和评价。对于RBFPD,临床评价了1987-2002年间使用硫酮底漆作为金属修复剂(Metalite或V-Primer)和粘接树脂(Super-Bond C&B)植入的81个RBFPD的固位力。存活分为两个水平:(1)完全存活(无脱粘)和(2)功能存活(包括一次性丧失保留和原始RBFPD的重新结合)。所有数据都是从临床检查中获得的,缺失的数据在最后可用信息的日期进行了审查。平均生存期采用Kaplan-Meier程序确定。在81个RBFPD中,有5个修复失败,其中一个可以重新粘接。完全生存观察时间为165个月,相应生存率为43.9%;功能生存观察时间为178个月,相应生存率为87.7%。在牙齿缺失、缺失牙齿和基牙的位置和数量以及基牙准备的类型方面,这些因素对寿命没有统计学上的影响,尽管生存曲线显示出不同的趋势。对于树脂贴面,经过一年的评估期后,评估的修复体显示出临床上的成功。结果表明,含贵金属修复剂的树脂粘结系统对银-钯-铜-金合金固定修复体具有较好的临床应用价值。
