Oral implant denture is a new type of oral prosthesis that has been rapidly developed in recent decades. It is supported by artificial implants (similar to the roots of natural teeth) implanted in the jawbone, which can eliminate or reduce the size of the abutment, feel comfortable, have a good retention effect, and restore the chewing function to a degree close to that of real teeth, overcoming the shortcomings of traditional fixed and removable denture. The implant can also transfer the chewing force directly to the jawbone, forming a functional stimulus to the bone tissue at the implant site and delaying the process of resorption and atrophy of the alveolar bone. Therefore, implants have greatly improved the quality of life of patients and are called the “third set of human teeth” after milk teeth and permanent teeth. After 30-40 years of development and long-term, multi-center clinical observation, dental implants have become a mature, reliable and successful new technology, and there are records of cases where dental implants are still intact for more than 30 years. It has been widely accepted as the preferred treatment option for missing teeth in Western countries. Of course, there are strict indications for dental implants, and not all conditions can be treated with dental implants. The treatment and restoration of dental implants is divided into three stages. (1) First, preoperative examination and treatment, such as extraction of particularly loose teeth and root remnants, filling of carious teeth, treatment of periodontal disease, adjustment and correction of bad occlusal relationship, etc. The time required for this stage varies depending on the treatment situation of each individual. (2) Implant surgery stage: Implant surgery is a small outpatient surgery that requires only local anesthesia, the same as the anesthesia used for general tooth extraction. The implant is surgically placed in the bone by the surgeon according to the preoperative design, and the postoperative reaction is low. (3) Two to four months after the surgery, the integration of the bone tissue with the implant is completed and the restoration phase is entered with the installation of a permanent crown or denture. Due to modern advances in material science and research, the integration of bone tissue with the implant is faster and better with the use of new implant surface treatments, and the minimum time required to start the veneering phase is six weeks, allowing the patient to obtain a denture sooner.
