Background And Aim:
The custom-made finger prosthesis is aesthetically acceptable and comfortable for use in patients with amputated fingers, resulting in psychological improvement and physiological well being. The success of the prosthesis depends on the precision of planning the prosthesis, making the impression, carving the model and choosing the material that best suits the concerned circumstances. In this article a simplified method was used regarding an accurate impression of partially amputated fingers.
Technique:
A plastic cylindrical small open container (impression cap) was used for making an impression of the fingers. A wax pattern of the missing part was made by replicating the same fingers of the other hand with melted modelling wax after slight modification. This pattern was finally cured with silicone material.
Discussion:
In the present technique, a modified approach of impression making was used for getting an accurate fit of the finger prosthesis with improved aesthetics, which is one of the most important criterion for the success of any prosthesis.
