Buccal crossbite (also known as Brodie syndrome, or scissor bite) is a malocclusion where the palatal cusp of a maxillary tooth is buccal to the buccal cusp(s) of the opposing mandibular dentition. Lingual crossbite occurs when the maxillary buccal cusp(s) is/are lingual to the buccal cusp tip(s) of the opposing mandibular tooth. Brodie defined a malocclusion as a "Brodie bite" or "Brodie syndrome" when the lower jaw "telescoped" within the maxillary arch (i.e. the mandibular teeth were completely contained within the maxillary arch). The first consideration for scissor bite correction is to determine, if orthognathic surgery is necessary. Brodie Syndrome/bite is a rare form of transverse malocclusion. It was named after Allan G. Brodie, who was the first author to present the case of a patient with this malocclusion in 1952.  Other names can be found in the literature: Brodie bite, exaggerated occlusion, or even scissors bite.
