Abstract
Statement of Problem: With the increase in use of SLM to fabricate dental prosthesis, is
there a compromise in mechanical properties when compared to casted dental prosthesis. Purpose: The aim of this study is to mechanical test removable dental prosthesis (RPD) with 2 different means of fabrication, SLM and conventional casting with castable resin printed
by SLA and by 2 different clasp designs, c-clasp and RPI.
Materials and Methods: A total of 9 RPD frameworks were fabricated, divided by 3 for
the 3 groups, C-clap casted, C-clasp SLM, and RPI casted. A digital design was made on CAD software and an STL file was generated. A castable resin and the SLM were fabricated by the same STL file. Each RPD was tested for 10,000 cycles of insertion and removal, and retentive forces measured.
Results: There was no significant difference between all 3 groups with the SLM C-clasp having the highest initial retentive force followed by the RPI.
Conclusion: SLM may be used for economic advantages to fabricate dental prosthesis without the compromise of mechanical properties found in the casted dental prosthesis.
