Although many patients have no problem wearing an upper denture, some people find it difficult to wear and eat with lower dentures. Several implant-supported replacement options are available if you are missing all of your lower teeth.
One option is to have two implants placed in your lower jaw and a denture made that snaps onto these implants. This option allows your lower denture to be more stable while chewing than without implants. However, there will still be movement of your lower denture, and sore spots will occur if any food particles, especially seeds, are caught under it. As with all removable replacement teeth, you still will need periodic appointments for denture adjustment.
An extraordinary procedure has been developed that permits placement of 4 dental implants and a fixed bridge in as little as one appointment. In its most extraordinary application an entire mouthful of teeth may be replaced with implants and non-removable set of new teeth in as little as one day. In most cases there is no bone grafting.
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 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.
