Summary
Using vinyl polysiloxane for altered cast fabrication allows speech aid prosthesis try-in at the wax stage. This method avoids double processing, significantly saving laboratory time and resources.
Area of Science:
- Dental prosthetics
- Materials science in dentistry
Background:
- Fabricating complete speech aid prostheses typically involves multiple processing stages.
- Traditional methods can be time-consuming and require significant laboratory resources.
Purpose of the Study:
- To evaluate a modified fabrication technique for complete speech aid prostheses.
- To determine if vinyl polysiloxane can streamline the prosthesis fabrication process.
Main Methods:
- Incorporation of vinyl polysiloxane during the altered cast fabrication stage.
- Enabling prosthesis try-in at the wax stage, prior to final processing.
Main Results:
- Successful trial fitting of the complete speech aid prosthesis at the wax stage was achieved.
- The technique eliminated the need for a preliminary processing step.
Conclusions:
- Utilizing vinyl polysiloxane in altered cast fabrication simplifies speech aid prosthesis construction.
- This streamlined approach reduces laboratory time by avoiding double processing.
