& nbsp, Dental implants; & nbsp; & nbsp; The duration of use of dental implants depends on various factors, including porcelain-fused-to-metal crowns, but the main factors are as follows: & nbsp; & nbsp; & nbsp; 1. The patient's own condition: such as sufficient bone volume (including height and thickness), suitable bone density, and good gum conditions can lead to a longer service life, while the opposite will affect the lifespan of the denture. & nbsp; & nbsp; & nbsp; 2. The experience of the implant dentist: The precision requirements for implant surgery and restoration techniques are extremely high. Doctors must have undergone specialized training and education. They also need a certain amount of clinical experience to correctly complete each step of the implant treatment and handle various special situations encountered during treatment smoothly, thereby ensuring the long-term effect of the implant restoration. & nbsp; & nbsp; & nbsp; 3. Selection of the implant system: Implant systems have strict requirements and standards in terms of production processes, design shapes, connection methods, machining accuracy, upper structures, and sterilization packaging. The several imported implant systems selected by our department are all well-known implant systems with over 20 years of successful clinical application records internationally, and they have all passed the inspection and certification of the US FDA, European CE, and China SDA, ensuring reliable quality. & nbsp; & nbsp; & nbsp; 4. Patient's maintenance and cleaning of the implant dentures. Implant dentures should be kept clean, and regular follow-up visits to the hospital are required to avoid infection around the implant tissues and maintain the long-term use of the implant dentures. Smoking has a negative impact on the long-term effects of implant dentures.
