When a single tooth is missing in the mouth of a patient, the implant is only needed to be driven into the missing tooth part, and then the implant is provided with components such as an abutment, a dental crown and the like, so that the restoration can be completed. When a plurality of teeth are missing in the mouth of a patient, the teeth are required to be repaired, if a repairing mode of single tooth missing is still adopted, the planting nail needs to be driven in for many times in the repairing process, so that great burden is caused to the alveolar bone of the patient, the alveolar bone is easy to damage, and once the alveolar bone is damaged, the repairing effect is difficult to ensure.
Thus, when multiple tooth loss occurs, the restoration is generally performed through a dental bridge. The dental bridge includes a dentition provided with a plurality of tooth monomers connected in sequence. The process of repairing a plurality of tooth loss through a dental bridge is as follows: firstly, an implant is driven into the edentulous part, and then the dentition is fixedly installed on the implant. Generally, only two implants are needed to be correspondingly arranged on one dentition, so that a good fixing effect can be achieved, and excessive burden on alveolar bones can be avoided. However, the position and orientation of the implant must be very precise to ensure the installation and subsequent restoration of the dentition. The invention aims to provide a technical scheme which is suitable for ensuring the installation precision in the process of repairing a dental bridge when a plurality of teeth are missing.
