The purpose of this study was to investigate the effect of resin cement type on the retentive strength of custom zirconia abutments bonded to titanium inserts.
Sixty implant (4.3 mm diameter and 11.5 mm length) and custom zirconia abutment (15 mm height and 2 mm wall thickness) pairs were used to form six groups (n = 10 each). Three different resin cements were used to bond the zirconia abutments and titanium inserts: Panavia F 2.0, Zirconite, and Multilink Hybrid Abutment. Control groups and thermomechanically aged groups were formed. Specimens were subjected to tensile test to failure, and the retention values were analyzed by two-way analysis of variance (ANOVA).
Two-way ANOVA showed a significant effect of the cement type and thermomechanical aging (P < .05). Regardless of the cement, control groups showed significantly (P < .05) higher retentive strength than the thermomechanically aged groups. Comparing the resin cements, the retentive strength of Zirconite, aged or not, was higher than that of Panavia F 2.0 and Multilink Hybrid Abutment; no significant differences between the latter two cements were found. In the Zirconite group, adhesive failure occurred mostly between the titanium and the resin cement. In the Panavia F 2.0 and Multilink Hybrid Abutment groups, adhesive failure between the zirconia and the resin cement was observed.
Resin cement type had an effect on the retentive strength of custom zirconia abutments bonded to titanium inserts. Thermomechanical aging had a negative effect on the retentive strength. Zirconite adhesively bonded to the zirconia surface of the custom abutment. Differences were noted in adhesive failure types among the cements.
本研究旨在探讨树脂水门汀类型对粘结于钛植入体上的定制氧化锆基台固位强度的影响。
使用60对种植体（直径4.3 mm，长度11.5 mm）和定制氧化锆基台（高度15 mm，壁厚2 mm），分为6组（每组n = 10）。使用三种不同的树脂水门汀粘结氧化锆基台和钛植入体：Panavia F 2.0、Zirconite和Multilink Hybrid Abutment。形成对照组和热机械老化组。对标本进行拉伸试验直至破坏，并通过双向方差分析（ANOVA）分析固位值。
双向ANOVA显示水门汀类型和热机械老化有显著影响（P < .05）。无论使用何种水门汀，对照组的固位强度均显著高于热机械老化组（P < .05）。比较树脂水门汀，Zirconite无论是否老化，其固位强度均高于Panavia F 2.0和Multilink Hybrid Abutment；后两种水门汀之间未发现显著差异。在Zirconite组中，粘结失败主要发生在钛和树脂水门汀之间。在Panavia F 2.0和Multilink Hybrid Abutment组中，观察到氧化锆和树脂水门汀之间的粘结失败。
树脂水门汀类型对粘结于钛植入体上的定制氧化锆基台的固位强度有影响。热机械老化对固位强度有负面影响。Zirconite粘结于定制基台的氧化锆表面。不同水门汀的粘结失败类型存在差异。
