Finite Element Analysis of Stress Distribution in Healthy and Restored Mandibular Molars with Zirconia and Lithium Disilicate Crowns Under Vertical and Oblique Loading

The mechanical compatibility between dental restorative materials and the natural tooth structure is a relevant factor for long-term clinical performance. Although zirconia (yttria-stabilized tetragonal zirconia polycrystal, Y-TZP) and lithium disilicate are widely used for full-...

Ultrasound-Assisted Enzymatic Processing of Grasshopper (Sphenarium purpurascens): Comparative Assessment and Characterization of Protein Hydrolysates

The increasing demand for sustainable protein sources has stimulated interest in edible insects such as the Mexican grasshopper (Sphenarium purpurascens). This study evaluated grasshopper flour as a substrate for producing protein hydrolysates by ultrasound-assisted enzymatic hyd...
