This time around I initially made both maxillary and mandibular record bases from shellac… then I broke both of them while relieving the frenums with a hot knife. In the end I made both record bases from Triad light-cure material, which was a pleasure to work with.

As pictured here, I haven’t quite finished trimming the frenums on the bench motor. Please forgive the not-quite-focused photos (I took them with my phone rather than with my camera).

Tomorrow: on to occlusal rims and hopefully mounting / articulating my casts.
