Treatment of severe scissor bite in a middle-aged adult patient with orthodontic mini-implants.

Scissors bite is a rare form of malocclusion that is often accompanied by varying degrees of facial asymmetry. Transverse discrepancies in adults are very difficult to treat, especially in cases that also exhibit vertical overlapping of the posterior teeth. This case report illustrates the use of orthodontic mini-implants (OMIs) to treat a severe scissors bite in a middle-aged man. Absolute anchorage and lingual fixed appliances can successfully treat skeletal, dental and functional problems associated with scissors bite. Pretreatment, posttreatment, and retention records in this patient demonstrate effective and stable treatment results with few side effects.
