Area of Science:

  • Prosthodontics
  • Materials Science

Background:

  • Occupational trauma can lead to partial finger amputation, impacting a patient's quality of life.
  • Restoring aesthetics and function after digit loss is crucial for social reintegration.

Purpose of the Study:

  • To describe the fabrication of a custom finger prosthesis for a patient with partial finger loss.
  • To detail the modified impression and wax pattern techniques used.
  • To highlight the importance of accurate color matching and retention methods.

Main Methods:

  • A modified impression technique was employed for accurate mold creation.
  • A specialized, easily moldable and carvable wax was formulated for the pattern.
  • Indexed casts and intrinsic/extrinsic staining were used for precise finger length and skin color matching.
  • A ring served as the primary retention mechanism for the prosthesis.

Main Results:

  • A functional and aesthetically matched finger prosthesis was successfully fabricated.
  • The prosthesis accurately restored the finger's length and blended with the patient's skin tone.
  • The patient reported high satisfaction due to improved social acceptance.

Conclusions:

  • Custom finger prostheses can effectively restore form and function after occupational trauma.
  • Advanced impression, material, and coloration techniques are vital for successful outcomes.
  • The use of prosthetics significantly enhances patients' psychological well-being and social integration.
