I worked on making a three unit bridge from tooth #19 through to tooth #21 earlier this semester. Tooth #19 and #21 were prepped for PFM crowns and served as abutments for pontic #20.
1. Impression was taken of the maxillary and mandibular arches, then mounted
2. #19 and #21 were prepped (not pictured)
