What are the main advantages of dental implants? 1. No need to wear the healthy teeth on both sides of the missing area; 2. The closest to the appearance of natural teeth; 3. The closest to the feeling of natural teeth (the teeth feel like natural teeth after the implant is completed); 4. The closest to the function of natural teeth (the implant is closely bonded to the bone and can withstand normal biting forces and prevent alveolar bone resorption) Is the process of dental implantation painful? Some people are afraid of dental implants mainly because of the concept that dental implants require surgery, so they are afraid. In fact, dental implants are just like ordinary tooth extraction, and many patients even feel that the discomfort of implant placement surgery is a little less than tooth extraction. Can elderly people have dental implants? Yes. Implant dentures are not age specific and many elderly patients who suffer from missing teeth can also share the benefits of this successful technology. Your dentist will conduct a thorough evaluation of your physical condition, and dental implants are possible as long as you are in good health and are able to do so. Can I get an implant if I have no teeth in my mouth? Yes. If you are able to have more implants, you can opt for a full mouth fixed implant, which is convenient and comfortable for the patient without having to remove it. If conditions do not allow, 2 to 4 implants can be placed, which can greatly improve the function and comfort of the whole mouth. How should dental implants be maintained? After all, dental implants are different from the original teeth, so they should be taken care of when they are used: firstly, you should not use too much force to avoid excessive stress on the implants. Secondly, we should pay attention to the cleaning, and routinely go to the hospital 1-2 times a year to review the implants, in addition to the regular cleaning, and if necessary, deep cleaning of the dental implants. Contraindications to dental implants: 1, abnormal occlusal and intermaxillary relationships: in general, abnormal occlusal and intermaxillary relationships are not suitable for implant restorations, unless the abnormal intermaxillary and occlusal relationships can be corrected at the same time; 2, pathological changes in the local alveolar bone: such as residual roots, foreign bodies, granulomas, cysts and inflammatory reactions, after eliminating the above pathological change factors can then be considered for implant restorations; 3, jaws that have undergone radiation therapy; 4, oral Mucosal lesions: leukoplakia, erythema, lichen planus and other systemic lesions associated with stomatitis or dry mouth syndrome; 5. Patients with progressive periodontitis; 6. Patients with restricted mouth opening.
