摘要/Abstract

摘要： 目的: 观察瓷贴面类型及树脂水门汀对瓷贴面边缘密合度及微渗漏的影响。方法: 36颗上颌中切牙随机均分为四组进行贴面修复,A组:IPS e.max Press瓷贴面+RelyX^TM Veneer树脂水门汀;B组:IPS e.max Press瓷贴面+Vitique树脂水门汀;C组:CAD/CAM长石质瓷贴面+RelyX^TM Veneer树脂水门汀;D组:CAD/CAM长石质瓷贴面+Vitique树脂水门汀。贴面粘接后经冷热循环老化、亚甲基蓝染色,在显微镜下观测贴面唇面中央及近远中轴角区纵截面边缘密合度及微渗漏情况。结果: A、B、C、D组平均密合度分别为(0.037±0.007) mm、(0.044±0.012) mm、(0.046±0.014) mm、(0.038±0.004) mm,龈边缘染料渗入平均深度分别为(0.143±0.085) mm、(0.148±0.087) mm、(0.236±0.074) mm、(0.158±0.036) mm,组间均无显著差异。B、C、D组近远中轴角区微渗漏情况重于唇面正中区。结论: 单颗贴面内部不同区域密合度较一致,但近远中轴角区微渗漏情况更严重,贴面类型及树脂水门汀对瓷贴面平均边缘密合度及微渗漏无显著影响。

Abstract: Objective: To investigate the influence of veneer type and resin cement on margin adaptation and microleakage of ceramic veneer. Methods: Thirty-six maxillary central incisors were selected and received veneer preparation, then randomly divided into 4 groups. Group A:IPS e.max press veneer + RelyX^TM Veneer; Group B:IPS e.max press veneer + Vitique; Group C:CEREC Blocs CAD/CAM veneer+ RelyX^TM Veneer;Group D: CEREC Blocs CAD/CAM veneer+ Vitique. All teeth underwent a thermocycle aging process and immersed in 2% methylene blue solution. The margin adaptation and dye infiltration depth were measured under the stereomicroscope at different axis section. Results: The margin spaces of four groups were (0.037±0.007) mm, (0.044±0.012) mm, (0.046±0.014) mm, and (0.038±0.004) mm, respectively. The dye infiltration depths of four groups were (0.143±0.085) mm, (0.148±0.087) mm, (0.236±0.074) mm, and (0.158±0.036) mm, respectively. There was no significant difference between groups, however, significant difference in the dye penetration depth between different sections of group B, C, and D. Conclusion: More serious microleakage was often detected at the mesio and distal section of the single veneer. The veneer type and resin cement impose no particular influence on average margin adaptation and microleakage.
