Residual root, that is, the root left after the crown is destroyed, most patients feel pain from time to time when they see their incomplete root, and they feel useless and should be pulled out. However, if your residual roots can be properly handled and fully utilized in time, it will bring you great benefits.

1, using residual roots as a simple root post or metal core post to restore the crown, this way is called post crown, which is comfortable and beautiful enough to confuse.

2. When a few teeth on both sides of the residual root are missing, the quality of denture will be greatly improved by using the treated root as post crown retainer or metal core retainer.

3. After the residual roots are made into metal caps, removable overdentures are made. At this time, it can not only retain the function of alveolar ridge, slow down the absorption of alveolar bone, but also facilitate the transmission of bite force and prevent denture from sinking, just like a pier hidden in water. It plays an important role in the stability of bridges.

4. When most of the teeth in the whole mouth are missing, retaining the residual roots is beneficial to the retention of the denture, increasing the stability of the denture and improving the restoration effect.
