  • PRACTICE Unilateral Posterior Crossbite with Mandibular ...

    2012-4-20 · Based on this literature review, early orthodontic treatment of unilateral posterior crossbites with mandibular shifts is recommended. Treatment success is high if it is startedearly. Evidence that crossbites are not self-correcting, have some association with tem-poromandibular disorders and cause skeletal, dental and muscle adaptation provides further rationale for early treatment. It can be difficult to treat unilateral crossbites inadults without a combination of orthodontics and surgery. The most appropriate timingof treatment occurs when the patient is in the late deciduous or early mixed dentitionstage as expansion modalities are very successful in this age group and permanent incisorsare given more space as a result of the expansion. Treatment of unilateral posterior cross-bites generally involves symmetric expansion of the maxillary arch, removal of selectiveocclusal interferences and elimination of the mandibular functional shift. The generalpractitioner and pediatric dentist must be able to diagnose unilateral posterior crossbitessuccessfully …
