AIM
Aim of this in vitro study was to compare the tensile bond strength of UniFil Bond (GC America) vs iBond (Heraeus Kulzer) in conjunction with light cure composite resin (Venus, Heraeus Kulzer).
MATERIALS AND METHODS
Sixty mandibular molars were taken and divided into 3 groups which were treated with UniFil Bond, iBond and no adhesive respectively. The tensile test was performed using an Instron machine.
RESULTS
The results showed that multibottle systems (UniFil Bond, i.e., two-step)performed 30% better as compared with single bottle systems (all-in-one, i.e., one-step bonding agents).
CONCLUSION
It can be concluded that UniFil Bond (Multibottle system - 6(th)generation type I) performed better than iBond (Single Bottle system - 7th generation.
目的
本体外研究的目的是比较优斐尔粘结剂（GC美国公司）与iBond粘结剂（贺利氏古莎公司）结合光固化复合树脂（维纳斯，贺利氏古莎公司）时的拉伸粘结强度。
材料与方法
选取60颗下颌磨牙，分为3组，分别用优斐尔粘结剂、iBond粘结剂和不使用粘结剂进行处理。使用英斯特朗材料试验机进行拉伸试验。
结果
结果表明，多瓶系统（优斐尔粘结剂，即两步法）与单瓶系统（一体式，即一步法粘结剂）相比，性能要好30%。
结论
可以得出结论，优斐尔粘结剂（多瓶系统 - 第6代I型）比iBond粘结剂（单瓶系统 - 第7代）性能更好。
