What is Phase I and Phase II treatment?
Phase I, or early interceptive treatment, is limited orthodontic treatment (i.e. expander or partial braces) before all of the permanent teeth have erupted. Such treatment can occur between the ages of 6 and 10. This treatment is sometimes recommended to make more space for developing teeth, correction of crossbites, overbites, underbites, or harmful oral habits. Phase II treatment is also called comprehensive treatment, because it involves full braces when all of the permanent teeth have erupted, usually between the ages of 11 and 13.
Phase I, or early interceptive treatment, is limited orthodontic treatment (i.e. expander or partial braces) before all of the permanent teeth have erupted. Such treatment can occur between the ages of six and ten. This treatment is sometimes recommended to make more space for developing teeth, and correct crossbites, overbites, underbites, or harmful oral habits. Phase II treatment is also called comprehensive treatment, because it involves full braces when all of the permanent teeth have erupted, usually between the ages of eleven and thirteen.
First-Phase Treatment (Interceptive) Children sometimes exhibit early signs of jaw problems as they grow and develop. An upper or lower jaw that is growing too much or not enough, or is to wide, too narrow, or crooked can be recognized at an early age. If children over four years of age have these jaw discrepancies, they are usually candidates for early orthodontic/orthopedic evaluation and treatment.Because children are growing rapidly, they can benefit enormously from an early (interceptive) phase of orthodontic/orthopedic treatment. Orthodontic appliances can be used to correct the jaw shape and direct the growth toward an ideal relationship between the upper and lower jaws. A good foundation can be established thereby providing adequate room for eruption of all the permanent teeth.Interceptive treatment can also decrease the time necessary for the second phase of treatment. Leaving a malocclusion untreated until all of the permanent teeth erupt could result in a jaw discrepancy too
Phase I (early interceptive) treatment, is limited orthodontic treatment (ex: expander or partial braces) before all the permanent teeth erupt. Such treatment can occur before the permanent teeth erupt. This treatment may be recommended to make more space for developing teeth, to correct crossbites, overbites, underbites, or harmful oral habits. Phase II treatment is also called comprehensive treatment, because it involves full braces when all the permanent teeth erupt, usually between the ages of eleven and thirteen. The female patient’s permanent teeth normally erupt one year earlier than the male patient’s permanent teeth. Consequently, the gender timeline varies. Hereditary factors also play a part in early or later eruption of permanent teeth and may affect when Phase II treatment begins.
Phase I, or early interceptive treatment, is limited orthodontic treatment (i.e. expander or partial braces) before all of the permanent teeth have erupted. Such treatment may be beneficial between the ages of six and ten. This treatment is sometimes recommended to make more space for developing teeth, correction of crossbites, overbites, underbites, or harmful oral habits. Phase II treatment is a full set of braces applied later (age 11 to 14) for someone who had Phase I interceptive treatment. Phase I is not always necessary; one comprehensive phase may be all that is needed instead of two phases.
