In clinical practice, patients always ask how long do dental implants last? Can they last a lifetime? I always answer: You can’t guarantee a lifetime of use even if your own natural teeth break down, how can I guarantee a lifetime of use for a dental implant? In fact, people tend to see only the advantages of dental implants and magnify them, while neglecting the maintenance of dental implants, which is largely dependent on the patient himself. The maintenance of dental implants is the same as that of other restorative prostheses, the main and most crucial thing is the cleaning of the denture. The maintenance of dental implants requires attention to the following aspects: 1) Self oral hygiene: 1) Brushing: use toothpaste with low abrasive particles, use a soft-bristled toothbrush, and adopt the modified BASS brushing method; 2) Flossing: apply to the interdental space where the interdental papillae are not significantly receding, once a day. 3) Gap brush: Use when there is a “black triangle” gap between the dental implant and the natural tooth. When brushing the gap between the implant and the natural tooth, it is important to note that the metal part of the gap brush should have a nylon outer layer so that the metal part of the gap brush does not come into direct contact with the implant surface to avoid damage to the implant surface; 4) Use of the flosser: It is recommended that the flosser be used twice a day. To prevent damage to the mucosal closure, the water flow should only be directed into the adjacent space or rinsed in the horizontal direction. 5) Mouth rinsing: you can use oral rinse after meals, or rinse with salt water. Second, office maintenance 1) Chlorhexidine can inhibit Gram-positive and negative anaerobic bacteria, aerobic bacteria, fungi, yeasts and some viruses. You can use 0.1%-0.2% chlorhexidine solution to rinse the area; 2) implant mechanical cleaning instruments: polishing brush, rubber cup, Teflon plastic, carbon or titanium scraper, plastic scraper, special PEEK fiber ultrasonic workstation and pneumatic sandblasting. Third, regular follow-up and discomfort follow-up. Generally 1 month, 3 months, 6 months, 12 months when the follow-up, and then once a year. If you have any discomfort, you should consult the doctor in time for early detection and treatment. In conclusion, the completion of the restoration of dental implants is only the first step in a long journey.
