The denture base supports the artificial teeth and consequently receives the functional forces from occlusion & transfers functional forces to supporting oral structures. Different definitions of acids and bases. Acids are proton donors (. Brønsted. Lowry definition). they generate H. 3. O. +. in water (Arrhenius definition). Bases are proton acceptors. they generate OH.
