The retention of the band and loop space maintainer over the stainless steel crowns (SSCs) dictates the success of the space maintainer. Using two widely used luting agents, this study assesses the binding strength between SS bands and the most popular SSCs as well as the recently released Bioflx crowns.
This study consisted of 48 samples divided into four groups. Type I glass ionomer cement (GIC) and resin-modified glass ionomer cement (RMGIC) were used to cement stainless steel (SS) bands over SSCs and Bioflx crowns. The shear bond strength was tested using a universal testing apparatus. To determine the degree of significance, one-way analysis of variance (ANOVA), Tukey's test, and a -value maintained at ≤0.05 were utilized.
The shear bond strength between the SSC and RMGIC (0.908 ± 0.20 MPa) was statistically significant and higher than between the SSC and GIC (0.362 ± 0.21 MPa). Though not statistically significant, the binding strength between Bioflx crowns and GIC was stronger than between Bioflx crowns and RMGIC.
The SS bands bonded well to the SSCs with RMGIC, and there was no significant difference between the SSCs and Bioflx crowns with GIC as the luting agent. Cohesive failures were common with GIC, and adhesive failures were common with RMGIC in both crowns.
The present study's findings can help clinicians make informed decisions when choosing crowns and luting agents for teeth with SSCs.

带环及间隙保持器在不锈钢冠（SSCs）上的固位决定了间隙保持器的成功与否。本研究使用两种广泛应用的粘结剂，评估不锈钢带环与最常用的不锈钢冠以及最近推出的Bioflx冠之间的粘结强度。
本研究共48个样本，分为四组。使用I型玻璃离子水门汀（GIC）和树脂改性玻璃离子水门汀（RMGIC）将不锈钢（SS）带环粘结在不锈钢冠和Bioflx冠上。使用万能测试仪器测试剪切粘结强度。为确定显著性程度，采用单因素方差分析（ANOVA）、Tukey检验，且P值保持在≤0.05。
不锈钢冠与树脂改性玻璃离子水门汀之间的剪切粘结强度（0.908±0.20MPa）具有统计学意义，且高于不锈钢冠与玻璃离子水门汀之间的强度（0.362±0.21MPa）。虽然无统计学意义，但Bioflx冠与玻璃离子水门汀之间的粘结强度强于Bioflx冠与树脂改性玻璃离子水门汀之间的粘结强度。
使用树脂改性玻璃离子水门汀时，不锈钢带环与不锈钢冠粘结良好，以玻璃离子水门汀作为粘结剂时，不锈钢冠和Bioflx冠之间无显著差异。在两种冠中，玻璃离子水门汀常见内聚破坏，树脂改性玻璃离子水门汀常见粘结破坏。
本研究结果可帮助临床医生在为有不锈钢冠的牙齿选择冠和粘结剂时做出明智决策。
