Cast Abutments

Cast patient-specific abutments are fabricated using a UCLA abutment (plastic sheath with a cast to machined platform interface) by the technician.

New Image Dental Laboratory works with UCLA abutments to make cast abutments from numerous implant companies including: Biomet 3i, Nobel Biocare, Zimmer, Astra Tech, Straumann, Dentsply Friadent, BioHorizons, Lifecore, Sybron Innova, BTI and Thommen.

Fabricating a Cast Abutment

We start by waxing over the UCLA abutment to achieve the ideal shape, contour, and emergence profile needed for the individual restoration.

The technician then sprues and invests the pattern and places it in a burnout furnace. Once the ring is at the correct temperature the technician casts the abutment out of a prescribed alloy. We use yellow gold alloy for anterior and high palladium alloy for posterior abutments. After devesting the cast abutment, it is finished and polished.
