A dental implant is a "root" device, usually made of titanium, used to support restorations that resemble a tooth or group of teeth to replace missing teeth.
The dental implants are root-form endosseous implants, i.e., they appear similar to an actual tooth root and are placed within the bone. The bone of the jaw accepts and osseointegrates with the titanium post. Osseointegration refers to the fusion of the implant surface with the surrounding bone. Dental implants will fuse with bone and thereafter when the implant is properly integrated in the bone then it can be finally loaded with the dental prosthesis. Dental implants can be used to support a number of dental prostheses, including crowns, implant-supported bridges or dentures.
FULL MOUTH REHABILITATION
There are times when the patients are not satisfied with complete denture and want the prosthesis which look similar to that of natural dentition. In those cases, 6-12 implants can be placed in upper and lower jaws each. After this a waiting period of 4-6 months is observed thereafter abutments are placed over the implants and proper jaw relation is taken so that the prosthesis provides a perfect facial height.
After the jaw relation is complete, impression is taken and is send to the laboratory. After the completion of prosthesis in the laboratory, it can be fixed in the form of implant supported bridges or implants supported individual crowns.
