Document Summary
Purpose/function: preserve arch length following the premature loss of a primary tooth, allows permanent tooth to erupt unhindered into proper alignment and occlusion, recommended after extraction of primary molar. Types: fixed, appliance of choice if a restorable abutment teeth are available, reduces the incidence of broken/loss appliance c, 4 basic types. Provides resistance to the pressure of the early mesial shift that occurs as the permanent first molar begins its eruption. For bilateral loss of primary molars before the eruption of permanent incisors. Crown and loop - requires preparation of abutment tooth for ssc. Cases that need guidance of eruption (sequential extraction) f. For premature loss of primary second molar but requires the permanent first molar be erupted sufficiently to fully seat a band. Band is seated on an intact primary first molar with the loop extending distally to contact the mesial of permanent molar. Construction: select an appropriate band or ssc.
