The final option is to have all your teeth individually replaced so that they will appear to be growing out of your gum tissue and will most closely resemble the appearance of your natural teeth. This option usually requires eight or more implants
. Separate abutments or support posts for each one of these implants will be made and crowns for each missing tooth will be placed. The teeth are often joined together for sinus grafting
to replace bone height strength and support. Overall, this is the most costly option, because it requires the most implants and individual replacement tooth fabrication. Your replacement options may also be limited by the current size and shape of your jawbone.
