To evaluate the shear bond strength (SBS) and adhesive remnant index (ARI) scores of metal brackets to glazed lithium disilicate reinforced glass-ceramics and zirconia according to various surface treatment protocols.
A total of 240 lithium disilicate ceramic (LD) and 240 zirconia (Zr) blocks were randomly divided according to sandblasting, hydrofluoric acid (HF) etching, universal primer use, and the adhesive system applied. A maxillary canine metal bracket was bonded to each sample with resin cement (Transbond XT, TXT). SBS tests and ARI score analysis were performed. Four-way ANOVA followed by Tukey's post hoc test was used for SBS differences, and Fisher's exact test was used for the ARI scores (p < 0.05).
All groups combining a universal primer with a universal adhesive with and without sandblasting provided satisfactory SBS values for both LD and Zr. Fractures of the samples were observed only for LD in the groups combining HF with universal primers and universal adhesives with and without sandblasting.
Combining a universal primer with a universal adhesive could be recommended for orthodontic bonding to both LD and Zr. Regarding their risks (i.e., damaging the restoration surface or burning the oral tissues), sandblasting or HF might not be necessary despite the presence of glaze covering the ceramic surface.
根据不同的表面处理方案，评估金属托槽与釉质锂硅酸增强玻璃陶瓷及氧化锆之间的剪切粘结强度（SBS）和粘结剂残留指数（ARI）评分。
将总共240块锂硅酸陶瓷（LD）和240块氧化锆（Zr）块根据喷砂、氢氟酸（HF）蚀刻、使用通用底漆以及所应用的粘结系统进行随机分组。用树脂水门汀（Transbond XT，TXT）将上颌尖牙金属托槽粘结到每个样本上。进行SBS测试和ARI评分分析。对于SBS差异，采用四因素方差分析并随后进行Tukey事后检验，对于ARI评分采用Fisher精确检验（p < 0.05）。
所有将通用底漆与通用粘结剂结合使用（无论有无喷砂）的组，对于LD和Zr均提供了令人满意的SBS值。仅在将HF与通用底漆以及通用粘结剂结合使用（无论有无喷砂）的组中，观察到LD样本出现断裂。
对于LD和Zr的正畸粘结，推荐将通用底漆与通用粘结剂结合使用。鉴于喷砂或HF存在风险（即损坏修复体表面或灼伤口腔组织），尽管陶瓷表面有釉质覆盖，喷砂或HF可能并非必要。
