Introduction: Currently there are different types of materials for the preparation of base plates, as a
procedure for the preparation of dental prostheses. The option of the thermoforming sheet, which is currently
of little use, as well as, of self-curing acrylic, a material of daily use in consultation. Objective: To compare
the techniques for making base plates, to determine which of the two provide qualities such as shorter
processing time and less deformity. Materials and methods: 20 models of gypsum totally edentulous were
selected for convenience, to which processing time is recorded and the same laboratory tests are applied.
Results: The thermoformed base plates have an average time of 7 minutes, while the self-polymerized acrylic
base plates have an average time of 29 minutes, based on the laboratory analysis the least deformation occurs
in the acrylic base plate of autopolimerization. Conclusion: The time of preparation of the thermoformablebase plate is less, while the deformation is greater compared to the base plate of self-polymerizatíon, the latter
in turn, has a longer processing time than the thermoformable base plate.
