SERRANO HERNANDEZ, L; BARCELO SANTANA, FH  and  SANTOS ESPINOZA, A. Transverse deflection of polymer-based alternative materials for the manufacturing of a denture base. Rev. Odont. Mex [online]. 2013, vol.17, n.3, pp.146-151. ISSN 1870-199X.

Nowadays, alternative techniques are being developed for short-time manufacturing of full prostheses, entailing different materials for the denture base. The purpose of the present study was to compare transverse deflection among polymer-based materials currently proposed as an alternative to materials commonly used to conventionally manufacture a full prosthesis. For the denture base the following materials were tested: thermo-cured (setting) acrylic resin, self-cured acrylic resin, 60 and 80 gauge acetate sheets coated with self-cured acrylic resin, liquid (fluid) acrylic resin as well as light-cured resin. Ten 65 x 10 x 2.5 mm samples of each material were manufactured. The samples were placed in water at 37°C for 50 hours. Transverse deflection was measured and results were analyzed with the help of one-way analysis of variance (ANOVA). Results exhibited statistically significant differences among groups. Acetate sheets coated with self-cured acrylic could represent an alternative for the rapid manufacturing of temporary denture basis.

Keywords : Transverse deflection; polymers; denture base.
