The transpalatal arch: an alternative to the Nance appliance for space maintenance.
The loss of multiple primary molars in the primary or transitional dentition will, in many instances, lead to disturbances of the developing dentition. To prevent this, an appliance can be constructed to maintain the relationship of the remaining teeth and to guide the eruption of the developing teeth. Traditionally, the treatment of choice for maxillary loss is the placement of a Nance appliance. An alternative appliance that may be considered for use is the transpalatal arch or bar. The purpose of this clinical report was to describe the transpalatal arch appliance and present its advantages over the more common Nance appliance, thus encouraging clinicians to prescribe its use in certain clinical situations.
