This is my favorite way to do a mandibular pick-up. Prepare adequate depth wells to accommodate Smart Denture Conversions Ti bases secured to the multi-unit abutments with the Separable Fasteners. Cut the LINGUAL flanges and distal extensions of the denture so that the patient can rotate into the prepositioned mandibular denture in ideal occlusion with the upper denture. "Bond" the denture to the opposing dentition/denture/prosthesis using a small amount of Triad gel on the canines and first molars (you may need to use the Triad Bonding Agent). Be sure any part you don't want to be picked up in the denture are blocked out with Kool-Dam, by Pulpdent (i.e., sutures or parts of the multi-unit abutment exposed above the gingiva). Now, inject your pick-up material of choice into the intaglio of the suspended mandibular denture and around the Ti bases being picked up. Manipulate the patient closed into centric relation using chin point guidance being sure the patient doesn't deviate from centric relation during the cure time. Once material is cured, chip the Triad gel nubs away and remove the lower denture from the multi-unit abutments and proceed with the laboratory process to complete the prosthesis. Voila!
See how the mandibular denture has the lingual flanges removed and I also removed the distal extensions. This particular case also had the buccal flanges removed, but that isn't necessary, nor preferred in an immediate situation. The buccal flange serves as an indicator of appropriate vertical dimension.
