GoldCast Abutment

Castable abutment with a prefabricated gold base (Au/Pt/Pd) for Osstem TS implants. For custom abutments in high-gold alloy when path of insertion, available space or aesthetics cannot be solved with stock abutments – for cement-retained and combination restorations.

CASTING PRINCIPLE

Prefabricated connection, custom post

The connection to the implant is precisely factory-made from a high-melting gold alloy (Au/Pt/Pd, 1400–1450 °C); the post is individually waxed up and cast on. This solves unfavourable implant axes, tight spaces and special emergence profiles. Cast on with high-gold alloys only whose casting temperature is well below the melting range of the base – no non-precious alloy.

ORDER NUMBERS

WORKFLOW

From model to cast abutment

1. Take an implant-level impression and make the working model with the matching lab analog.
2. Fix the GoldCast abutment on the analog with the lab screw – hex or non-hex according to the restoration.
3. Wax up the post individually – observe the manufacturer's limits for minimum height and angulation.
4. Invest and cast with high-gold alloy, casting temperature well below 1400 °C. Do not machine or sandblast the implant connection surface.
5. Finish, check on the model and fabricate the crown or bridge – veneer with ceramics if required using a suitable bonding alloy.
6. Place in the mouth with a new EbonyGold screw: mini 20 Ncm, regular 30 Ncm.
