The casts were verified using an index made on the patient model. Five Galunisertib cast high palladium noble alloy and five CAD/CAM titanium alloy frameworks were fabricated. The patient’s implants and the frameworks’ implant restorative platforms were scanned with a tactile probe, and the data were digitized. The digitized implant restorative platforms of the frameworks were fit onto the patient’s digitized implants via a software program, in a process called “lofting.” This computerized procedure simulated a 1-screw test; the process was performed on both sides. The volumetric misfit between the implant restorative platforms of the frameworks and
the patient’s implants were measured. A Welch’s t-test was used to determine significant differences (p < 0.05)
between the misfit of the two technologies. Wilcoxon Signed-Rank tests were used to evaluate differences between the right and left sides. Results: On average, the volumetric misfit of the CAD/CAM frameworks was 1.8 mm3 less than the volumetric Talazoparib manufacturer misfit of the cast alloy frameworks (p < 0.05). The Wilcoxon Signed-Rank tests showed no significant differences between the right and left sides within both systems (p > 0.05). Conclusions: The scanning technology and computer software program used in this study demonstrated that the CAD/CAM implant frameworks had statistically significantly less volumetric misfit when compared with the cast implant frameworks. There were no significant differences between the right and left 1-screw tests within the same type of frameworks. “
“Purpose: This study evaluated the effect of metal reinforcement and its location on the flexural load at the proportional limit (FL-PL) and the flexural deflection of maxillary acrylic resin complete dentures. Materials and Methods: Maxillary acrylic resin complete dentures
reinforced with Remanium and without reinforcement MCE were tested. The reinforcing material was embedded in the denture base resin in the doughy state and placed (1) under the ridge lap region; (2) in the anterior region; (3) in the middle region; and (4) in the anterior and posterior regions. The FL-PL (N) and the flexural deflection (mm) at 100 N of the reinforced maxillary denture specimens were tested using a load testing machine at a 5.0 mm/min crosshead speed. The data were analyzed statistically using one-way ANOVA; Tukey’s post hoc comparisons test was applied when appropriate (95% confidence level). Results: The FL-PL of the dentures without reinforcement (909 ± 195 N) and the dentures reinforced at the ridge lap (1094 ± 176 N) and in the middle (977 ± 215 N) regions were not significantly different (p > 0.05). The dentures reinforced in the anterior (1348 ± 205 N) and the anterior and posterior (1190 ± 191 N) regions had a higher FL-PL than the dentures without reinforcement (p < 0.05) and were not significantly different from each other (p > 0.05).
