Computer-aided methods in bespoke breast prosthesis design and fabrication

Area of Science:

• Biomedical Engineering
• Medical Device Design
• Prosthetics

Background:

• Mastectomy patients often require external breast prostheses.
• Existing prostheses may lack a precise fit and natural aesthetic.
• Customization can significantly improve patient comfort and satisfaction.

Purpose of the Study:

• To present a novel method for fabricating bespoke external breast prostheses.
• To demonstrate the application of computer-aided design (CAD) and rapid prototyping in prosthesis creation.
• To achieve a personalized fit and appearance for post-mastectomy patients.

Main Methods:

• Photogrammetry was used to capture breast and defect site geometry.
• CAD software generated a digital prosthesis model based on captured data.
• A two-part mold was designed and fabricated using rapid prototyping.
• A color-matched prosthesis was created using platinum-cured silicone.

Main Results:

• A digital prosthesis model was successfully generated.
• A custom-fit prosthesis with a matching surface to the defect site was designed.
• Rapid prototyping enabled the fabrication of a two-part mold.
• A color-matched silicone prosthesis was produced.

Conclusions:

• Computer-aided design and rapid prototyping offer a viable method for creating bespoke external breast prostheses.
• This technique allows for precise customization, improving fit and aesthetics.
• The developed method holds potential for enhancing the quality of life for mastectomy patients.
