The principle of implantation after tooth loss, or dental implant as it is commonly known, is based on the placement of a titanium implant into the missing tooth bed at the missing site. The healing time is usually determined by the bone density of the missing area and the need for bone grafting. Osseointegration of the implant with the bone takes place in 3-6 months, and the clinician takes a mold and places a clinical crown and bridge on top of the implant. The characteristic of dental implants is that the structure and function are similar to natural teeth, so the chewing function is very strong, and it overcomes the disadvantages of movable denture which needs to be removed and cleaned, and it does not need to grind the two natural teeth adjacent to the affected tooth, so it is a boon to the patients, and now it has become a treatment method preferred by oral implantologists in clinical practice. That is why patients are now advised when they visit a regular hospital that a removable denture is an option, and a fixed denture is also an option. Although dental implants are now gradually becoming popular in society, because they still require clinicians to have more experience in implantation and require higher implantation direction and loci, patients are advised to try to go to regular hospitals for examination and implantation to avoid problems in the future.
