云纹干涉法测量不同载荷条件下金属-瓷标本的位移
Application of moiré interferometry method in measurement of displacement of metal-porcelain restorations
摘要
Abstract
BACKGROUND: Moiré interferometry method which belongs to the range of experiment mechanics is a modern photo-mechanics test technique. On the other hand, metal-porcelain restorations characterized as beautiful, compatible and stable properties are widely used in oral medicine domain. Moiré interferometry technique is applied in the oral restoration and some mechanics data can be obtained. It can be realized in discipline complementation and interaction between mechanics and bio-medicine engineering. OBJECTIVE: To introduce the moiré interferometry technique in details, and to study the displacement of metal-porcelain restorations under different loads by using the moiré interferometry technique as it is found that porcelains often flake off from the base of restorations in oral clinic. METHODS: The horizontal and vertical displacement of metal-porcelain restorations were measured by using the moiré interferometry method which is sensitive and easy to operate, and suitable for in-plane displacement measurement. The displacement was shown in the form of interferometry patterns. RESULTS and CONCLUSION: The interferometry patterns which represented the in-plane displacement of specimens were obtained and the displacement was linearly related with the loading changes. Moiré interferometry method can be used in measuring the displacement of restorations. Operation is simple and results are shown by interferometry patterns.关键词
