DENTAL ARCH AND AIRWAY EXPANDER DEVICE AND METHOD
摘要:
A method and apparatus with auto-inactivation for the lateral expansion or constriction of posterior teeth, anterior advancement or retraction of the anterior teeth, and distal expansion of the molars, bicuspids and canines is described. This system is for correction of the upper dental arch and jaw bone, nasal cavity constriction, or lower dental arch constriction, which helps to resolve the dental malposition, dental crowding, proper room for tongue position, and expansion of nasal cavity for improvement of airway. The appliance includes loaded springs around the wires connected to molar band with connector tubes and female attachments that are extended to the front tube. The spring creates a distalization force on the first and/or second molars, anterior extending force on front teeth including canines and incisors, and lateral expansion for the posterior teeth including, canines, bicuspids and molars.
