Clinical tips for the Halterman appliance.
Ectopic eruption of permanent first molars occurs infrequently and causes some resorption of the adjacent primary second molar. The primary second molar can be used as an anchor tooth for the Halterman appliance to disimpact the permanent first molar, provided root resorption is not extreme. A modification of the Halterman appliance is a reverse band and loop appliance with a bonded button on the permanent molar and chain elastic for disimpaction. The purpose of this report was to suggest tips regarding placement and clinical management of this modified Halterman appliance design.
