A patient presented with a large dental cavity missing a buccal cusp on a molar. The dentist prepared the cavity, placed a matrix band and wedge to maintain proximal contact, and used a V3 Blue Ring to adapt the matrix during restoration with composite. After rebuilding the proximal wall, the ring and matrix were removed, leaving a completed and finished restoration.
