Following tooth loss, alveolar bone has a tendency to be absorbed1–3. The loss of supporting bone often results in shrinkage of soft tissue and creates aesthetic problems in the perioral skin. This is especially true when anterior teeth have been missing for a relatively long period. A prosthesis, including dentures or implants, can partially compensate for the lost tissue and collapsed facial profile. However, once wrinkles have formed in lip skin, the correction of this aesthetic problem may not be fully achieved by prosthesis alone.
