Four resin veneering materials and four methods of retaining the veneer on metal castings were compared with metal ceramic restoration. Variations in microleakage were noted between the four resin materials retained by mechanical retention beads. When mechanical and chemical modes of a resin and porcelain veneer retention were compared, there was no microleakage with one mechanically and two chemically retained resin groups including one metal ceramic group. The resin materials tested understandably produced substantially lower shear bond strengths than the metal ceramic specimens. Higher shear bond strengths were recorded for the retentive beads than for the resins retained by three chemical bonding techniques. There was no direct correlation between microleakage and shear bond strength.
将四种树脂贴面材料以及四种在金属铸件上固定贴面的方法与金属烤瓷修复体进行了比较。通过机械固位珠固定的四种树脂材料之间，微渗漏存在差异。当比较树脂和瓷贴面固位的机械和化学模式时，在一个通过机械固位以及两个通过化学固位的树脂组（包括一个金属烤瓷组）中未发现微渗漏。可以理解，所测试的树脂材料产生的剪切粘结强度明显低于金属烤瓷试件。固位珠的剪切粘结强度高于通过三种化学粘结技术固定的树脂。微渗漏与剪切粘结强度之间没有直接关联。
