If inadequate space exists for permanent teeth to erupt, Dr. Wall recommends expansion of jaws rather than extraction of teeth. Expansion makes more room for the tongue, which enlarges the airway, provides a more favorable jaw position, fosters good head posture and expands the cranial base. Research shows that expansion orthodontics increases the IQ (The Dental Physician, Al Fonder). Dr. Wall has treated children with dento-facial expansion who were struggling in school prior to treatment, then progressed to the honor roll near the end of treatment. Expansion can be accomplished either with fixed or removable appliances or with the Damon orthodontic system.
The Damon orthodontic system utilizes self-ligating brackets and light force wires to effortlessly move teeth and expand jaw bones. Treatment times are shortened and extractions and expansion appliances are often avoided.
