Abstract
VALVERDE FAJARDO, Stefanny and RAMOS MADRIGAL, Maikol. Development time and the deformity degree of the thermoformed base plate compared to the acrylic base plate of self-polymerization. Odontología Vital [online]. 2019, n.31, pp.11-18. ISSN 1659-0775.
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 thermoformable base 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.
