Dental implant is a technique to surgically implant an artificial material into the alveolar bone of the missing tooth area as an artificial tooth root, and then use it as a basis to restore the missing tooth. The treatment process of dental implant generally includes pre-operative evaluation, phase I surgery and phase II restoration. 1. Pre-operative evaluation: the doctor should be provided with medical history, blood pressure measurement, blood tests, dental films, CBCT, curved tomography and lateral cephalometric films, etc. to rule out any abnormalities. 2. The implant will be buried in a cavity, and then sutured tightly in the dental bone bed, and the stitches can be removed in 7-10 days after surgery. After the healing period, a model is made first, then a denture is made on the upper end of the implant and connected with a connector. The implant is then molded and restored, and finally a fitting is performed. After a successful fitting, the final restoration is cemented and ready for use. Dental implants also need to be reviewed regularly afterwards, usually every 0.5-1 year.
