While sitting, scoot your butt to the front of your chair. Then lean back so that your upper back rests lightly on the seat back. Contract abs and lift your right knee up, then place your foot back down on the floor. Repeat with your left leg, doing 10 reps on each side. Then, sit up straight on the front edge of your chair, engage abs and lean back again to lean upper back against the chair back. Sit up straight again, using your abs.
A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent bridge is placed. A Flipper can be attached via either a wire or a plastic piece that fits in the roof of your mouth. Flippers are meant to be a temporary solution while awaiting the permanent bridge.
A removable partial denture or bridge usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is sometimes connected by metal framework that holds the denture in place in the mouth. Partial dentures are used when one or more natural teeth remain in the upper or lower jaw. A fixed bridge replaces one or more teeth by placing crowns on the teeth on either side of the space and attaching artificial teeth to them. This bridge is then cemented into place. Not only does a partial denture fill in the spaces created by missing teeth, it prevents other teeth from changing position.
