The repair abutment is the intermediate connector used for crown repair after the implant has completed healing. The repair abutment is fixed by screws and connected to the inside of the implant to form a certain pillar, and then the crown is repaired on the repair abutment. This is a more traditional repair method, there are one-piece abutments and split repair abutments. The healing abutment is placed in the gums during the healing process to allow the gums to form a certain cuff and form a good tissue-periodontal interface. After the interface or shape is formed, the repair abutment is applied, which can effectively repair the teeth and avoid the occurrence of food impaction and other phenomena.
