Dental implants are generally made of titanium and are surgically implanted in the upper and lower jaws, where they are firmly anchored by bone tissue and connected by special devices and methods to support the upper dental prosthesis. Dental implants can achieve a restorative effect very similar to the function, structure and aesthetic effect of natural teeth, and have become the preferred restorative method for more and more patients with missing teeth. There are five procedures for dental implants: 1. Preoperative examination, treatment planning, necessary periodontal treatment, and health promotion. Pre-operative examination mainly includes oral examination and imaging examination, and local dental CT to clarify the bone condition. Perfect preparation, healthy periodontal conditions and good living habits are necessary to ensure the success and long-term use of dental implants. 2. Implant placement surgery: Titanium implants are surgically placed in the alveolar bone to form new roots for the next dental placement. However, if there is not enough bone in the alveolar bone, bone grafting surgery is required. The general implant procedure is relatively simple and painless, so there is no need to worry. 3. Attachment of the implant superstructure: The implant, which has been healed with bone, is attached to the mouth by some special instruments to facilitate the placement of teeth. 4. Implant placement: Wearing artificial crowns, or restoring movable dentures. 5. Maintenance of dental implants and regular review. Cost: The cost varies greatly from place to place and from hospital to hospital depending on the local economy and the level and level. In our hospital, the cost varies according to whether bone implants are needed or not. Overall, the cost is about 20,000 per tooth, but the cost is lower for those who do not need bone implants, and higher for those who need bone implants according to the difficulty.
