摘要:: [摘要]目的：探究四甲基硅烷（TMS）与苯等离子体连续沉积对树脂与牙科氧化锆陶瓷粘接的粘接强度的影响。方法：将55
个氧化锆陶瓷片随机分为TMS组、苯等离子体组、TMS+苯等离子体组、氧化锆涂底剂（ZPP）组及对照组，每组11个氧化锆陶
瓷片。按照分组给予不同的氧化锆表面处理，采用X射线光电子能谱分析仪观察各组表面化学元素含量及种类，采用透射电
子显微镜观察TMS+苯等离子体组表面涂层结构，采用剪切粘接强度试验观察给予不同表面处理后各组粘接强度及断裂模式。
结果：TMS组、苯等离子体组、TMS+苯等离子体组、ZPP组碳原子含量及碳氧比均低于对照组（P ＜0.05）。透射电镜图像显

Abstract:: Abstract:Objective To investigate the effect of plasma deposition of tetramethylsilane (TMS) and benzene on resin bonding
to dental zirconia ceramic. Methods A total of 55 zirconia specimens were randomly divided into five groups for different
treatments, TMS group, benzene plasma deposition group, TMS+ benzene plasma deposition group, zirconia primer plus
(ZPP) group and control group, each with 11 specimens. The surface chemical compositions were characterized via X-ray
photoelectron spectroscopy. The surface coating structure of TMS+benzene plasma group was observed by transmission electron
microscope. Shear bond-strength test was used to observe the bonding strength and fracture mode of each group after different
treatments. Results The carbon atom content and carbon-oxygen ratio of TMS group, benzene plasma deposition group, TMS+
benzene plasma deposition group and ZPP group were lower than those in control group (P ＜0.05). X-ray spectroscopy showed
that two layers on ZrO2 were formed through sequential deposition with TMS and benzene. The bond strength of TMS group,
benzene plasma deposition group, TMS+ benzene plasma deposition group and ZPP group was significantly higher than that
in control group (P ＜0.05). The bond strength of TMS+ benzene plasma deposition group was significantly higher than that in
TMS group, benzene plasma deposition group and ZPP group (P ＜0.05). There were no cohesive fractures in each group, and
the highest proportion of mixed fractures was 100.00% in the TMS+ benzene plasma deposition group. Conclusion Application
of plasma deposition of TMS and benzene can significantly promote the resin bonding to dental zirconia ceramic.
