Miracle mixture is also called as silver alloy admix. Miracle Mix offers the proven formula of glass ionomer cement with 100% fine, silver alloy powder for lasting core build-ups, repair and block-outs.<\/p>\n\n\n\n
Miracle mixture has high radiopacity and a strong colour contrast. A significant number of liquid and powder modifications were soon incorporated in glass ionomers to improve the physical, chemical and mechanical properties.
Ag-Sn particles are admixed in some formulations to produce an amalgam substitute. This combination came to known as the \u201cmiracle mixture\u201d<\/p>\n\n\n\n
Composition<\/strong> Indications<\/strong> Properties<\/strong> Advantages<\/strong> Disadvantages<\/strong> Previously miracle mixture was used widely as it had Fluoride releasing property and Chemical bonding property of GIC and high compressive strength due to amalgum as compared to GIC. It had both the advantages from GIC as well as amalgam.

Nowadays as the dentistry has advanced and overcome the previous disadvantages there is minimum use of miracle mixture. Composite restorations are more popular as they are very aesthetic and match your tooth color. Miracle mixture is only used for temporary restorations or as occlusal stops in orthodontic treatment.<\/p>\n\n\n\n
