摘要
目的:本研究评估了采用两种边缘预备设计和两种全瓷材料制造的内冠的抗折性。方法:将 20 颗经过根管治疗的上颌前磨牙制备为内冠修复体,并根据制备设计分为两个相等的主组:对接设计的内冠和卡环设计的内冠(n=10)。根据使用的所有陶瓷材料,主组又分为两个相等的亚组:由 Vita Ambria 制成的内冠和由 Vita Suprinity 制成的内冠(n=5)。内冠修复体使用双固化自粘树脂粘结剂粘结在制备好的牙齿上。试样经过热循环处理。使用万能试验机对所有试样施加压缩力直至断裂。记录所有试样的最大压缩力,然后使用数码显微镜检查其破坏模式。结果:在两种材料的影响方面,Vita Ambria 和 Vita Suprinity 对抗折性的影响差异不显著(P=0.66)。在两种边缘制备设计的影响方面,对接设计和卡套设计对抗折性的影响差异不显著(P=0.73)。在失效模式方面,除 Vita Suprinity 与对接设计外,其他各组的所有失效模式均无显著差异。结论在这项研究中,Vita Ambria 和 Vita Suprinity 内冠无论是采用套圈设计还是对接设计都没有明显差异。
Influence of Different Marginal Preparation Designs on the Fracture Resistance of Vita Ambria and Vita Suprinity Endocrowns (An In Vitro Study )
Aim : This study evaluated the fracture resistance of endocrowns with two marginal preparation designs and manufactured with two all ceramic materials. Methods : Twenty endodontically treated maxillary premolar teeth were prepared to receive endocrown restorations and divided into two equal main groups according to the preparation designs; endocrowns with butt joint design and endocrowns with ferrule design (n=10). The main groups were subdivided into two equal subgroups according to all ceramic material used; endocrowns manufactured from Vita Ambria and endocrowns manufactured from Vita Suprinity (n=5). The endocrown restorations were cemented to the prepared teeth using dual cured self-adhesive resin cement. The specimens were subjected to thermo-cycling. All specimens were subjected to a compressive force until fracture by using universal testing machine. The maximum compressive force was recorded for all the specimens, then the failure modes were examined using a digital microscope. Results : Regarding the two materials effect, there were non-significant difference between Vita Ambria and Vita Suprinity on fracture resistance (P=0.66). Regarding the two marginal preparation designs effect, there were non-significant difference between butt joint and ferrule designs on fracture resistance (P=0.73). Regarding the failure mode, there was non-significant difference between all failure mode patterns in all groups except Vita Suprinity with butt joint design. Conclusion: There was no significant difference between Vita Ambria and Vita Suprinity endocrowns, either using ferrule or butt joint design in this study.
