Ensuring a secure bond between a framework structure and layering composite resin veneer is essential for a long-lasting dental restoration. A variety of primer systems are available to facilitate the adhesive bonding. Nevertheless, the growing preference for efficiency and simplicity in dentistry has made the one-bottle universal primers a desirable option. This study aims to compare the effectiveness of universal primers on the shear bond strength (SBS) of base metal alloy (BMA) and zirconia to layering composite resin. Each 160 BMA and zirconia 20 × 10 × 5 mm test specimen was fabricated. Eight different primers (SunCera Metal Primer, Metal Primer Z, Reliance Metal Primer, Alloy Primer, MKZ Primer, Monobond Plus, ArtPrime Plus, and Clearfil Ceramic Primer Plus) were applied to 20 specimens in each group. Subsequently, a 5 × 2 mm composite resin build-up was applied. SBS tests were performed after 24 h of water storage and after thermocycling (25,000 cycles, 5-55 °C). On BMA, after water storage for 24 h, the bond strength values ranged from 26.53 ± 3.28 MPa (Metal Primer Z) to 29.72 ± 2.00 MPa (MKZ Primer), while after thermocycling, bond strength values ranged from 25.19 ± 1.73 MPa (MKZ Primer) to 27.69 ± 2.37 MPa (Clearfil Ceramic Primer Plus). On a zirconia base, after 24 h, the bond strengths values ranged from 22.63 ± 2.28 MPa (Reliance Primer) to 29.96 ± 2.37 MPa (MKZ Primer) and from 23.77 ± 3.86 MPa (Metal Primer Z) to 28.88 ± 3.09 MPa (Monobond Plus) after thermocycling. While no significant difference in bond strength was found between the primers on the BMA base, five primer combinations differed significantly from each other on zirconia ( = 0.002-0.043). All primers achieved a bond strength greater than 23 MPa on both framework materials after thermocycling. Thus, all primers tested can be applied to both framework materials with comparable results.
确保框架结构与复合树脂贴面之间形成牢固的粘结对于持久的牙齿修复至关重要。有多种底漆系统可用于促进粘结。然而，牙科领域对效率和简便性的偏好日益增加，使得单瓶通用底漆成为一种理想选择。本研究旨在比较通用底漆对贱金属合金（BMA）和氧化锆与复合树脂贴面的剪切粘结强度（SBS）的有效性。制备了每组160个尺寸为20×10×5mm的BMA和氧化锆测试样本。将八种不同的底漆（SunCera金属底漆、金属底漆Z、Reliance金属底漆、合金底漆、MKZ底漆、Monobond Plus、ArtPrime Plus和Clearfil陶瓷底漆Plus）分别应用于每组的20个样本。随后，进行5×2mm的复合树脂堆积。在储存24小时水后以及热循环（25000次循环，5 - 55°C）后进行SBS测试。在BMA上，储存24小时水后，粘结强度值范围为26.53±3.28MPa（金属底漆Z）至29.72±2.00MPa（MKZ底漆），而热循环后，粘结强度值范围为25.19±1.73MPa（MKZ底漆）至27.69±2.37MPa（Clearfil陶瓷底漆Plus）。在氧化锆基底上，24小时后，粘结强度值范围为22.63±2.28MPa（Reliance底漆）至29.96±2.37MPa（MKZ底漆），热循环后为23.77±3.86MPa（金属底漆Z）至28.88±3.09MPa（Monobond Plus）。虽然在BMA基底上底漆之间未发现粘结强度有显著差异，但在氧化锆上有五种底漆组合彼此之间存在显著差异（P = 0.002 - 0.043）。热循环后，所有底漆在两种框架材料上的粘结强度均大于23MPa。因此，所有测试的底漆均可应用于两种框架材料，结果相当。
