Abstract

Aim: The aim of this study was to compare TENSILE STRENGTH of pre-solder and post-solder joints for three DENTAL ALLOYS. 45 rods, 32mm in length and 25mm in diameter were made from degubond 4 (Au-Pd-Ag), porson 4 (Pd-Ag) and verabond (ni-Cr-Be).Material and Methods: 15rods for each alloy randomly divided in to three groups of control, presolder and postsolder.10 rods of each alloy were cut in half with a custom made cutting Jig and then positioned and stabilized at 13mm gap distance in an indexing Jig. Rods of deubond 4 and porson 4 were given a heat treatment to simulate porcelain firing. Specimens were SOLDERed with manufacturers recommended SOLDER with gas-oxygen torch (pre-soldering). Verabond specimens were SOLDERed with gold and base-metal SOLDER. Tensile testing was done on an instron machine. Model AB 725-AM.SM.At cross head speed of 2mm1min and result were recorded in kilogram.Results: 1- For Degubond 4, techniques of SOLDERing has no sigificant effect on TENSILE STRENGTH of SOLDERjoints.2- For Porson 4, TENSILE STRENGTH of presolder joints is significantly stronger than post-solder joints.3- The TENSILE STRENGTH of presolder joints for degubond 4 and porson 4 are significantly stronger than verabond.Conclusion: TENSILE STRENGTH of SOLDER joints depends on different factors such as type of alloy and SOLDERing technique however this is not dearly predictable.
