Danville’s ABC Wedge simplifies wide-open box or missing cusp restorations for clinicians using sectional matrix or trimmed Tofflemeier bands. The ABC Wedge supports both sectional and trimmed Tofflemeier. When inserted from the buccal and lingual the wings support the band and secure the matrix to the gingival floor. Excessive decay frequently results in fractured cusps. Previously, the only alternative was a Tofflemeier band with an obtrusive retainer, which often created difficulty when restoring a tight, biomimetic contact.
