At this time, you can choose the fixed bridge or implant denture, combined with porcelain teeth for restoration, the so-called fixed bridge is the gap on both sides of the original teeth are ground down one layer, the application of a three-connected ceramic teeth worn on both sides of the ground down on top of the teeth, similar to the establishment of a bridge between the two sides of the teeth to repair the missing tooth structure.
