Fixed partial denture, removable partial denture and implant denture can be chosen to restore the three missing teeth as follows. 1. Fixed partial denture: If there are enough abutment teeth to provide retention for three missing teeth, fixed partial denture can be chosen. However, the abutment teeth of fixed partial denture need to be partially abraded with healthy dental tissues, and the number of abutment teeth needed for repairing three missing teeth is high, and the total amount of teeth abraded is high. 2. Removable partial denture: using natural teeth, the mucosa and bone tissue under the abutment to provide support, the retainer and the abutment to provide retention, artificial teeth to repair the form and function of missing teeth, the amount of tooth abrasion is less than that of fixed denture, but the stability is not as good as that of fixed denture. The same disease, the patient’s condition is different, the choice of restoration is different, it is recommended to go to the hospital to receive regular treatment.
