Multisectional mold for fabrication of prosthetic ears

Area of Science:

• Biomaterials Science
• Prosthetics Engineering
• Anaplastology

Background:

• Fabricating prosthetic ears traditionally involves challenges with mold integrity and prosthesis damage during removal.
• Current methods may require significant force, increasing the risk of material failure.

Purpose of the Study:

• To introduce and advocate for a multisectional stone mold technique for prosthetic ear fabrication.
• To evaluate the advantages and disadvantages of this novel technique in terms of procedural ease and prosthesis quality.

Main Methods:

• Utilizing a multisectional stone mold approach for the fabrication process.
• Focusing on precise convergence of mold sections during the flasking stage.
• Documenting the force required during the deflasking procedure.

Main Results:

• The multisectional stone mold technique reduces the force needed for deflasking.
• This reduction in force minimizes the risk of fracturing the stone mold or tearing the silicone prosthesis.
• The technique demands increased time and meticulous care during the flasking phase.
• Potential for multiple section lines on the prosthesis may require more extensive surface finishing.

Conclusions:

• The multisectional stone mold offers a viable alternative for prosthetic ear fabrication, enhancing safety during removal.
• While requiring more meticulous flasking, the benefits of reduced deflasking force and minimized damage outweigh the drawbacks.
• Further attention to section line management is recommended for optimal aesthetic outcomes.
