NP-Cast Abutment

Castable abutment with a prefabricated CoCrMo base for Osstem TS implants. For custom non-precious abutments when path of insertion, available space or aesthetics cannot be solved with stock abutments – for crowns, bridges and bar constructions.

CASTING PRINCIPLE

Prefabricated connection, custom post

The connection to the implant is precisely factory-made from CoCrMo; the post is individually waxed up and cast on. This solves unfavourable implant axes, tight spaces and special emergence profiles – including bridges and bars in one casting. As the base is CoCrMo, cast with non-precious alloy (CoCrMo) only.

ORDER NUMBERS

NP-Cast abutments for Osstem TS

Suffix S = hex (anti-rotational, single crown), suffix B = non-hex (bridge, bar). Supplied with EbonyGold abutment screw.

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 NP-Cast abutment on the analog with the lab screw – hex or non-hex according to the restoration.
3. Wax up the post individually – height above the gingival section at least 4 mm, angulation max. 30°.
4. Invest and cast with non-precious alloy (CoCrMo). Do not machine or sandblast the implant connection surface.
5. Finish, check on the model and fabricate the crown, bridge or bar superstructure.
6. Place in the mouth with a new EbonyGold screw: mini 20 Ncm, regular 30 Ncm.
