A lot of people are missing all of their teeth, either in one or both arches and conventional dentures are often not a satisfactory solution. Traditional dentures rest on the gums and while they may fit well initially that often become ill fitting over time as the jawbone gradually changes shape.The jawbone will typically begin to change after your natural teeth are extracted because the bony ridge that used to support those teeth resorbs as it no longer has stimulation by the teeth roots. This ridge often becomes flatter and narrower which will make the dentures you originally had designed more difficult to comfortably wear and will provide less support for the facial muscles. This is why some people with dentures has a collapsed look to their face. These ill-fitting dentures may also begin to cause the patient difficulty with chewing certain foods and potentially even social anxiety as they begin to affect other areas of your life.
