The aim of this study was to compare the shear bond strength (SBS) and adhesive remnant index (ARI) scores of no-primer adhesives tested with two different bracket bases.
120 bovine permanent mandibular incisors were divided into 6 groups of 20 specimens. Two brackets (ODP) with different bracket bases (anchor pylons and 80-gauge mesh) were bonded to the teeth using a conventional adhesive (Transbond XT) and two different no-primer adhesive (Ortho Cem; Heliosit) systems. Groups were tested using an instron universal testing machine. SBS values were recorded. ARI scores were measured. SEM microphotographs were taken to evaluate the pattern of bracket bases. Statistical analysis was performed. ANOVA and Tukey tests were carried out for SBS values, whereas a chi-squared test was applied for ARI scores.
Highest bond strength values were reported with Transbond XT (with both pad designs), Ortho Cem bonded on anchor pylons and Heliosit on 80-gauge mesh. A higher frequency of ARI score of "3" was reported for Transbond XT groups. Other groups showed a higher frequency of ARI score "2" and "1."
Transbond XT showed the highest shear bond strength values with both pad designs.
本研究旨在比较两种不同托槽基底的无底漆粘结剂的剪切粘结强度（SBS）和粘结残留指数（ARI）评分。
将 120 颗牛恒切牙分为 20 个样本的 6 组。使用传统粘结剂（Transbond XT）和两种不同的无底漆粘结剂（Ortho Cem；Heliosit）系统将两种不同托槽基底（锚固塔和 80 号线）的托槽（ODP）粘结到牙齿上。使用 Instron 万能试验机对各组进行测试。记录 SBS 值。测量 ARI 评分。拍摄 SEM 显微照片以评估托槽基底的模式。进行了统计分析。对 SBS 值进行了 ANOVA 和 Tukey 检验，而对 ARI 评分则应用了卡方检验。
Transbond XT（两种垫板设计）、Ortho Cem 粘结于锚固塔和 Heliosit 粘结于 80 号线的粘结强度值最高。Transbond XT 组的 ARI 评分“3”的频率更高。其他组的 ARI 评分“2”和“1”的频率更高。
Transbond XT 两种垫板设计的剪切粘结强度值最高。
