Before working in the dental lab, I had never given much thought to a palatal obturator.  Before working with Dr. Amit Paryag, I had never seen a restorative dentist with such fire and keenness toward patient and product perfection - "patient centered care", as he refers to it.  When the two rolled in to one for us at Drake, something momentous was born. 

DID YOU KNOW? In 1560 Lusitanus was probably the first to describe what is today known as palatal obturator used for permanent luetic fistula of the palate (). In 1564 Ambroise Parè called his small obturators “couvercles”, and in 1575 changed the name to “obturateur" which is derived from the Latin “obturo” meaning to stop upIn 1634, Johson translated Parè’s “surgery”, published for king Henri the third.

Patients With Terminal Dentitions  .........................How to Avoid Extracting Teeth Before Immediate Denture Fabrication

To go with our video clip, here is a neat little article from IDT  about milling machines.  It explains a few basic workings and some comparative details - including wet versus dry.

At Drake, we do both - different options for different configurations, different materials, and different outcomes.
