Pre-eruption guidance
From Wikipedia, the free encyclopedia
Pre-eruption guidance is an orthodontic treatment method that allows for expansion of existing erupting teeth long before they appear in the mouth. The use off pre-eruption guidance appliances and the timing of extractions of certain deciduous teeth aligns the teeth naturally as opposed to orthodontic mechanical movement of permanent teeth into alignment after they have erupted. Research shows that pre-eruption guidance produces far more stable tooth alignment than alternative treatments.[1]
As defined by the American Dental Association and The American Association of Orthodontists, pre-eruption guidance therapy is a treatment method instituted with the use of bimaxillary bilateral removable space maintainers and the removal of the maxillary right and left deciduous cuspids [baby teeth] at very specific times to allow for a more optimal eruption pattern for permanent teeth to enter the mouth.[2] An integral part of the success of this treatment is the timely removal of certain deciduous teeth.
Pre-eruption guidance is distinctive because unlike other approaches, a patients' treatment results are achieved physiologically through muscle movements and removable functional spacer maintainers.[3] instead of mechanically through dental braces. This alleviates the need for braces to mechanically align or essentially repair the effects of mature teeth that erupted misaligned and crowded.[4]
