Treatment of Unilateral Posterior Scissors-Bite in a Mixed Dentition Patient

Posterior scissors-bite, also called as lingual crossbite is an occlusion which the buccal cusp of the mandibular molar occludes more lingually than the palatal cusp of the maxillary molar. Posterior scissors-bite can cause facial asymmetry, temporomandibular joint disorders (TMDs), and reduced masticatory efficiency. This case report presents the treatment of a patient in the mixed dentition stage with a unilateral posterior scissors-bite using a Schwartz appliance and cross elastics. Early treatment of the unilateral posterior scissors-bite is essential to prevent problems such as facial asymmetry and deep bite.
