The rapidly developing artificial dental implant technology, which is highly restorative to the natural teeth in terms of function and appearance, is regarded as the third set of teeth after the permanent teeth in the 21st century and has become the most advanced and important dental restoration method. So, who are suitable for dental implants? Dental implants are suitable for people who are in good general condition, no serious systemic diseases, physically and mentally healthy, and the bone and teeth development has been set. For older people, age is not an issue for such a procedure as long as they are in good health. In contrast, patients who are too young, below 18 years old, are better advised to undergo dental implantation after their growth and development has stopped because the jaw bone development is not set. Patients with specific chronic diseases, such as uncontrolled diabetes, heart disease and hypertension, blood disorders, osteoporosis and patients who need radiotherapy after oral cancer surgery, are not suitable to receive implant restorations immediately. In addition, patients who have recently had their teeth extracted should wait until the extraction wound heals and the bone morphology and quality of the implant bed are good before the implant surgery can be performed, usually more than three months after the extraction, while patients who have jaw bone or alveolar process surgery or trauma should be at least six months old and require good oral hygiene, no bad habits such as teeth grinding and smoking, no obvious inflammation or other lesions in the oral soft and hard tissues, and healthy oral mucosa. The implant area should have a sufficient thickness of attached gingiva. Dental implants are especially suitable for patients who have high requirements for prosthetic restorations that cannot be met by conventional restorations; or patients who are missing all their teeth and have poor results with traditional restorations; and patients who wear traditional removable dentures with poor retention and no function and whose mucosa cannot tolerate them. In most cases, dental implants are not a major surgery and can be done under local anesthesia. Only when the patient has poor alveolar bone conditions and needs bone grafting or implantation of more teeth will the surgery be performed under general anesthesia. The pain tolerance of each patient varies, but in general, the pain level after implant surgery is similar to that of tooth extraction. Can dental implants be done once and for all? Before surgery, many patients ask if dental implants are so expensive that they will last a lifetime, or how many years they will last after implantation. The answer varies from person to person. If the oral hygiene is poor and periodontitis occurs, the dental implant may loosen due to periodontal inflammation. Generally speaking, the retention rate of dental implants is about 80%. In order to prolong the service life of dental implants, patients should visit a regular dental hospital, use dental implants correctly according to the doctor’s prescription, maintain proper maintenance, keep oral hygiene, and review the implants on time. It is worth mentioning that since the nerve endings around the implants are not as rich as those of natural teeth, they are more susceptible to damage when subjected to abnormal chewing forces, so avoid biting hard objects such as shelled nuts and bones. As the quality of life continues to improve, many patients are constantly looking for the best shortcut to dental implants. Currently, dental implants have become very popular for restoring missing teeth, especially for middle-aged and elderly people who have been stuck with traditional dentures for a long time.
