Resin restoration: the advantage is direct bonding, can complete the restoration at once, reduce the number of times the patient re-visit, the disadvantage is that after a long time of resin restoration, even if many times using light-curing filling to reduce the shrinkage, but there may still be shrinkage. It is suitable for small degree of tooth loss, or the degree of caries damage only reaches one-third or less than one-third of the crown, it is recommended to perform resin restoration, because resin restoration can basically meet the filling needs. 2. Inlay restoration: the advantage is that there will be no shrinkage after the completion of the shape, because the inlay is made of porcelain material, after filling, less sensitive dentin, edge of the micro seepage and so on, the disadvantage is that the patient likes to eat sticky or hard food, inlay is easy to fall off.
