what is the negative reproduction of dental arches and surrounding tissues? *** impression
at what point in a procedure is a mylar matrix placed? *** before etching
the retainer (toffelmire) is positioned from what surface? *** buccal
,Where is the wedge inserted to position the matrix band firmly against the gingival margin? *** lingual
