First, the dental implant is surgically placed into the jawbone. It takes 3-6 months to fuse with the bone [called osseointegration]. An abutment [post] is attached to the implant and protrudes above the gum tissue. A replacement restoration is cemented or screwed to the implant abutment. Depending on the situation, dental implants can support a fixed crown or bridge or act as a stabilizing base for a full denture. The procedure can take up to 9-12 months for completion and has a high degree of success.
Some individuals have had so much bone resorption [loss] that the remaining bony ridge is too thin to hold an implant. In many cases, synthetic or natural bone can be grafted [added] or grown to allow for dental implants as an alternative treatment.
Implants have a great advantage for people already wearing full dentures since they can support and stabilize the denture while minimizing further bone loss of the denture ridge.
