1656-A-F ABSTRACT A dental method and apparatus for swiftly performing gingival retraction and conditioning in which a mass of moldable coherent plastic, preferably thixotropic, is lightly pressure molded both into and around the gingival trough of a prepared tooth to apply substantially balanced forces across the gingival flap which maintain the gingival trough without distortion. The moldable mass is rendered hydrosorbent at least on its surface by intimately bonded absorbent fiber, enabling it to absorb all the liquids and debris which would normally preclude the material from flowing into the trough. To effect a slight enlargement of the trough and to prevent prolapse in the case of very narrow troughs a preliminary bead of flowable thixotropic material can be injected into the through to transmit light lateral outward pressure on the flap when pressed into the through by the moldable absorbent mass.
