CASTABLE ABUTMENTS

Plastic castable abutments are intended for use by the technician for simple casting of custom-made abutments for constructing the prosthetic restoration. Use this technique for a lab-fabricated, custom, screw-retained crown, or cement retained. The custom crown can complement soft tissue contour, height and also can correct angulation.

When to use
- Single and multiple-unit restorations
- For aesthetic restorations when tissue is limited
- Minimum inter-arch space of 4 mm
- Screw and cement retained restorations
- Mild or moderate implant malposition

How to use

1. Make an implant level impression
2. Lab process
3. Pour the working model
4. Seat, mark, and modify the abutment (seat the selected custom castable abutment onto the implant analog in the working model)
5. Wax the custom abutment
6. Sprue, invest and cast the abutment
7. Divest, fit, and finish the abutment
8. Apply the porcelain
9. Seat the final restoration
10. Check and modify the restoration and take radiograph along the long axis of the implant to ensure that the crown is seated completely in the hex of the implant.
11. Tighten the abutment and screw (do not exceed 20 NCM, we recommend 15-20 NCM)
12. Fill the screw and access channel

Clinical advantages
- It is easier to correct the angulation of implants
- The final restorations are manufactured to the patients exact gingival architecture, achieving an optimal emergence profile and a more esthetically pleasing outcome.
- Clinical alternative to mild or moderate implant malposition
