All on Four Dental Implants: Case 49- DFW Implants A DFW patient had dental implants change his life. This is a case where we had planned to remove maxillary teeth and replace with a denture for the top only and perform a lower same day permanent All on Four. 1 year later, our patient came back and said "I want the upper denture gone and to replace it with a permanent". So that is exactly what we did. Please note, due to our patient wanting the upper permanent we have not finalized his prosthesis. In situations like this we will finalize them together.
