The current internationally recognized clinical statistics for dental implants show a five-year success rate of 95% and a ten-year success rate of over 90%. The failure rate of dental implants is lower than the failure rate of any other restorative modality. Patients with long-term total tooth loss are highly reduced due to atrophy and resorption of the dental bed. The most distressing problem for patients is the unstable wearing of dentures, especially the mandibular denture, which falls off when they open their mouths. If artificial dental implant technology is used, several or a dozen implants can be placed according to the jaw bone condition, which can solve the stability problem of denture more satisfactorily and restore and improve the chewing function. Dental implants have the following advantages: 1. No grinding or less grinding of adjacent teeth, reducing the damage to the real teeth, and then fixed dentures can be made. 2. Preventing the loss of alveolar bone after tooth loss and enhancing the “truth, beauty and goodness” of dentures. 3.To make you have the same appearance as real teeth, the same chewing and swallowing function. 4.Increase the adhesion of the movable dentures, so that the movable dentures will not be loose when eating or talking. 5.Increase your self-confidence and solve your problems after losing teeth. 6.Solve your psychological uncomfortable feeling of wearing dentures. 7.It can eliminate many inconveniences of wearing movable dentures, and there is no aesthetic obstacle or tooth decay problem caused by metal hook and loop of movable dentures. Artificial dental implants can be used in a variety of different tooth loss situations. However, as with any medical technology, there is a range of indications, and not every patient with tooth loss can have an implant placed: an oral examination, panoramic x-ray and routine blood tests should be performed by a medical professional before determining the suitability of the procedure. In case of bleeding disorders, hypertension, heart disease, diabetes, osteoporosis, psychosis, endocrine and other systemic diseases, dental implants should be accepted only after the disease has been treated and stabilized. For patients over seventy years of age, the decision should be based on the specific physical condition.
