Digital technologies enable precise reconstruction of implant-retained auricular prostheses. This method ensures an exact match in shape, color, and orientation, improving patient outcomes and reproducibility.
Area of Science:
- Biomedical Engineering
- Prosthodontics
- Digital Dentistry
Background:
- Implant-retained auricular prostheses offer successful restoration for ear defects.
- Digital technologies can optimize the aesthetic and functional outcomes of prosthetic ears.
Purpose of the Study:
- To describe a sequential digital workflow for reconstructing a missing ear using advanced technologies.
- To demonstrate the creation of an aesthetically pleasing and functionally accurate auricular prosthesis.
Main Methods:
- Utilized specialist biomedical software for implant planning via mirror imaging of the contralateral ear.
- Employed a surgical stent for accurate implant placement and digital segmentation/3D printing for prosthesis fabrication.
- Integrated digital color matching (spectromatch) for precise silicone coloration.
Main Results:
- Achieved an exact match in shape, skin color, and orientation of the prosthetic ear to the existing ear.
- Demonstrated optimized aesthetic results with no need for extrinsic coloring.
- Confirmed significant time savings and reproducible results due to the integrated digital workflow.
Conclusions:
- Digital technologies provide a highly accurate and efficient method for constructing implant-retained auricular prostheses.
- This workflow enhances patient satisfaction through superior aesthetic integration and functional restoration.
- The digital approach ensures consistent, reproducible outcomes, minimizing operator variability.
