After implantation, when the implant denture function is fully recovered, normal diet such as vegetables and meat with coarse fiber can be consumed, avoiding hard food such as bones and nuts, which may cause abutment loosening and fracture, superstructure screw loosening and fracture, and implant fracture. 1. Loose abutment fracture: It can be caused by bad occlusal loads, such as excessive lateral force, torsion force, resulting in stress concentration, and the superstructure loosening, shifting, and falling off. 2. Loosening and fracture of superstructure screws: This can be caused by excessive lateral force, which results in loosening and fracture of the screws, resulting in loosening and dislodging of the superstructure. 3. Fracture of implant: This can be caused by excessive occlusal force. Once fracture occurs, it is usually necessary to remove the original implant. If any of the above situations occurs, it is recommended to go to the hospital in time for early targeted treatment.
