It is seen that glass ionomer has the highest annual rate of failure, as they are glass silicates, they don’t have much sustainability. Poly acid composite acids are basically polymers and they have swelling thermal property, which is undesirable to use in dental restoration in some conditions. The selection of the alternative is based on minimum failure rate and the required properties for dental restoration. The resin based composite is best suited in this case, and we will going to discuss it in this report.
The shift in material science has projected the way of thinking towards the selection of those materials that would allow the least harm to the people. The discipline of material science has evaluated a new dimension called nanotechnology which would allow the making of different instruments at Nano level scale i.e. 10-9. One of the important reasons ofadvancing down to Nano scale is to ensure desirable properties of dentistry instruments.t is done by Nano coating on the substrate to alter the properties. Nano technology has opened the gates for the production of synthetic bone hydroxyl apatite “HAp” on Titanium substrate.
There are various fabrication technique available fabricate Nanomaterials such as plasma spraying, chemical vapour deposition, physical vapour deposition, sol-gel, etc. Each technique accounts for some specific properties that are required for any purpose. The other important method of dental restoration is resin coating. This is done by blocking the uncovered dentin which is a hard constituent shielded by enamel over the crown. The resin coat is provided on the side surface just after before producing a pattern by fixing the dentin bond structure. Resin coating helps to increase the strength of bond between the tooth and the applied resin. The material of thin coat is used to form a block filmed layer right on the formed dentin. Thin film plays the vital role to guard the dentin to form any kind of biological, physical or any chemical irritation. In addition to this, thin film layer is able to prevent any sort of leakage while restoring the crown. Keep in mind that the application of thin film is only applied to a localized area of cavity.
