Optimization of a nasal prosthesis supported by extraoral implants

Three implants placed close together, inclined towards each other and serving as the perfect basis for the magnets of a nasal prosthesis. Options are often limited in case of bone resorption and porosity. And yet we were able to offer a considerable optimization for both practitioner and patient.

Elos scan bodies as a starting point

Case set-up: three implants just below the nasal region are connected by means of a vertical bar to the magnets above to retain the patient’s nasal prosthesis.

The workflow was as follows:

1. We received the digital face scan with Elos scan bodies from the lab.
2. We implemented the data into our exocad software to determine the implant position.
3. After discussing the case with the practitioner, our designers went to work with industrial CAD software and created a design that served as a basis for a prototype. This prototype was first made of plastic so the practitioner could verify if the final structure was easy to work with and clean.
4. After approval by the customer and patient, we composed in-house a screw system based on the instruments available at the practitioner’s.
5. We manufactured the final product from titanium grade 5 and provided it with a rounded and cleanable smooth surface.

Inventive design and machined masterpiece

Based on our knowledge and experience, we advised to divide the design of the structure into two parts. As a basis, we provided a primary structure on two implants. A vertical secondary structure connected the third implant to the basic structure.

On this vertical structure, we placed the magnetic retainers for the prosthesis.

This enabled an accessible attachment of the implants by the practitioner, which in turn ensured additional stability and comfort for the patient.

In combination with the excellent skills of our medical-certified milling partner, we were able to guarantee an optimized final result at every level.

Our added value for the customer?

A great challenge in this case was the position of the three implants. Due to the patient’s bone condition, the surgeon had no other choice but to place them in this specific inclination angle.

By separating the design of the basic structure and the vertical bar, and connecting them using a surgeon-specific screw system, we were able to considerably simplify placement while providing perfect parallelism with the magnets. Thanks to the excellent work of our milling specialists.

Finally, we smoothened the surface for optimum patient comfort.
