Case facts
Patient:
A 78-year-old female patient in generally good health.
Clinical problem:
The patient presents with a failing tooth-supported telescopic bridge in the maxilla. The remaining maxillary teeth cannot be saved and require extraction.
Clinical solution:
The extraction of three maxillary teeth, followed by the immediate placement of four implants. Two of the posterior implants are placed at an angle for optimal support. Multi-Unit Abutments are installed immediately after implant placement. A provisional screw-retained bridge is placed on the same day as the surgery, with the final prosthesis scheduled for future placement.
Treatment plan:
- Extraction of three maxillary teeth.
- Immediate placement of four implants.
- Installation of four Multi-Unit Abutments.
- Use of four Multi-Unit Impression Coping Closed Tray.
- Application of four Multi-Unit Healing Caps.
- Installation of provisional screw-retained bridge.
Products:
4 Neoss ProActive Edge implants
4 Multi-Unit Abutment 30° 3.0 mm
4 Multi-Unit Impression Coping Closed Tray 6 mm
4 Multi-Unit Healing Cap
Conclusion:
The Neoss4+ treatment solution for the upper jaw involves the placement of four implants with Multi-Unit Abutments. A provisional screw-retained prosthesis is fitted on the same day as the surgery, with plans for the final prosthesis to be placed at a later date.

The two posterior implants (4.5 x 15 mm) were tilted to maximize the distance between the implants, to avoid the sinus, to maximize the contact with available bone, and to increase stability.

“Multi-Unit Abutments expand possibilities once more while the fundamental core idea of the system remains unchanged - simplicity together with dental solutions at the highest level.”
