Development and application of the castable ceramic inlay with coping by precious metal

本研究的目的是通过测量附着体的物理性能和观察附着体-陶瓷界面来评价附着体(CAPTEK^&lt；[0！R]&gt；)对陶瓷嵌体的影响。此外，还报道了目前的贵金属和烤瓷粘结材料的强度。Vintage Hello(Shofu Inc.)和IPS Empress I(I Voc Lar Vivadent AG)--融合到覆盖材料按照制造商的说明制备。用扫描电子显微镜对这些烤瓷修复材料进行了观察。弯曲强度测定采用Instron万能试验机(十字头速度：1 mm/min)(n=5)。断裂韧性(KIC)由压痕技术测定。标本厚度2 mm，直径6 mm。压痕载荷为9.8N。用Niihara公式(n=6)计算了断裂韧性，得到了以下结果：1.…的物理性质更多的女皇应对方式有了明显的改善。在断裂韧性(MNM-3/2)中，带冠的IPS Empress I的强度(1.57±0.06)显著高于不带冠的强度(1.39±0.15)(p&lt；0.05)。2.带冠的Vintage Halo^&lt；[0！R]的弯曲强度明显提高，但断裂韧性有所下降。有冠陶瓷的抗折强度(Mpa)(Vintage Hello 149.6±13.0，IPS Empress I 200.5±24.5)显著高于无冠陶瓷(82.9±3.0,151.4±5.7)(p&lt；0.0 5)。但Vintage Hello无盖组的断裂韧性(1.14±0.12)显著高于有盖组(0.90±0.08)(p&lt；0.05)。3.CAPTEK^&lt；[0！R]与陶瓷之间通过机械粘结紧密结合。4.CAPTEK^&lt；[0！R]的平均抗折强度高于HT、DG，DG和KiK介于两者之间。5.有盖的Empress I^&lt；[0！R]的适合度低于无盖的。较少

The purpose of this study is to evaluate the effect of a coping system (CAPTEK^<【○!R】>) on ceramic inlays by measuring the physical properties and observing the coping-ceramics interface. In addition, the strength of current sintering precious metal and porcelain bonded-to-metal are also reported.The precious-metal coping material, CAPTEK was used for the experiment. Vintage Hello (Shofu Inc.) and IPS Empress I (I voc lar Vivadent AG)-fused-to-coping materials were prepared according to manufacturers instructions. These ceramics-fused-to-coping materials were observed by SEM. The flexure strength was determined by using the Instron universal testing machine (crosshead speed : 1mm/min)(n=5). Fracture toughness (KIC) was determined by the indentation technique. The specimens were 2 mm in thickness and 6 mm in diameter. A load of 9.8 N was used for the indentation. Fracture toughness was calculated using Niihara's formula (n=6).The following results were obtained.1.Physical properties of … More Empress I^<【○!R】> with coping were definitely improved. In the fracture toughness (MNm-3/2), IPS Empress I with coping showed significantly greater strengths (1.57±0.06) than those without coping (1.39±0.15)(p<0.05).2.Flexure strength of Vintage Halo^<【○!R】 with coping was definitely improved, but fracture toughness had decreased. The flexure strength (MPa) of the ceramics with coping showed significantly higher values (Vintage hello 149.6±13.0, IPS Empress I 200.5±24.5) than the ceramics without coping (82.9±3.0, 151.4±5.7)(p<0.05). But the fracture toughness of the Vintage Hello without coping showed significantly greater strengths(1.14±0.12) than those with coping (0.90±0.08)(p<0.05).3.There was tight joint between CAPTEK^<【○!R】 and ceramics by mechanical bonding. The interfaces of IPS Empress I and Vintage Hello-fused-to-coping materials showed no gaps.4.Mean fracture strength of CAPTEK^<【○!R】 was higher than that of HT, DG and values found for DG and KIK were in between.5.Adaptation of Empress I^<【○!R】 with coping was inferior to that without coping.
