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.
Snap-In / Snap-Out
One option is to have two or four implants placed in your lower jaw, four implants for your upper jaw and a denture made that snaps onto these implants. This option allows your denture to be more stable while chewing than without implants. As with all removable replacement teeth, you still will need periodic appointments for denture adjustment.
Screw Retained Denture
A third option involves placing four or more implants in your jaw and attaching a permanent denture. Your denture is held in place by screws or clasps that secure it to the support posts or bar. It doesn’t touch the gum tissue, which allows you to clean under the denture without removing it. This denture will replace all your missing lower teeth and will not be removed except at maintenance visits. Although cleaning under your denture without removing it is more time consuming and requires more dexterity, many patients who want permanent teeth prefer this option.
