Description

Technical Field

[0001] The utility model relates to the technical field of tooth implantation, in particular to an auxiliary retention device for oral restoration of tooth implantation. Background Art

[0002] During the dental implant process, the oral cavity needs to be examined first, and then a preliminary implant surgery is performed to place the implant on the alveolar bone and wait for the implant to fit tightly with the alveolar bone. After the bone is tightly fitted, a healing base is installed to promote the formation of soft tissue. Currently, during the dental implant process, the patient's mouth needs to be kept open to facilitate the doctor's implant operation. During the use of the auxiliary retention device for oral restoration required for existing dental implants, the doctor needs to ensure that the patient's mouth is always open and then implant the teeth in the patient. However, generally, patients will unconsciously close their mouths after opening their mouths for a long time, which will affect the doctor's efficiency in implanting the teeth.

[0003] A Chinese patent discloses an auxiliary retention device for oral restoration of tooth implant (authorization announcement number CN219207403U). The patented technology is provided with a rectangular frame on the tooth retention mechanism, and the bidirectional threaded rod is threadedly connected to the screw hole opened in the middle of the rear end of the support frame, and the bidirectional threaded rod is movably connected to the rectangular frame through a bearing. Two supporting oral assemblies are threadedly connected to the front and rear of the outer surface of the bidirectional threaded rod. By manually twisting the twist handle, the twist handle can drive the two supporting oral assemblies on the bidirectional threaded rod to move in opposite directions, so that the sliding blocks fixedly connected to the upper ends of the connecting plates provided on the two supporting oral assemblies are located in the limiting grooves opened on the upper wall of the rectangular frame for forward and backward limiting movement, and at the same time, the rubber arc block fixedly connected to the lower end of the connecting plate through the rectangular hole can move in the opposite directions, so that the two rubber arc blocks can respectively abut against the front and rear jaws of the oral cavity, so that the mouth is always in an open state, so as to facilitate the doctor to implant teeth on the patient;

[0004] However, it has certain disadvantages: the entire device is large in size, and when in use, the position of the entire device must be adjusted, and then the height of the tooth retention mechanism must be adjusted so that the supporting oral component is located in the patient's mouth. Therefore, the operation is complicated and the use is not convenient. In addition, after use, the supporting oral component is not easy to disassemble, disinfect or replace. Utility Model Content
