There are fixed bridge restorations, removable denture restorations, and implant restorations, as follows: a. Fixed bridge restorations use the natural teeth on both sides of the missing tooth as abutment teeth, and make a retainer on the abutment teeth and connect it with the artificial teeth to form a whole, and cement the denture on both sides of the abutment teeth, which cannot be taken off and worn by the patient. Second, the movable denture restoration, using both sides of the natural teeth, as well as under the abutment mucosa, bone tissue as a support, is the patient can remove the restoration, the price is relatively cheap. The implant is placed in the alveolar bone of the missing tooth area, and after it is stabilized, the prosthesis is made on top of it to complete the restoration of the implant denture, which is more effective but relatively expensive. The above three restorative methods have their own advantages and disadvantages. If a tooth is lost and is to be repaired, it is recommended to actively seek medical examination and then choose a suitable restorative solution according to the situation.
