Hold with wooden sticks or metal rods- block undercuts – separating medium – cast – dovetails- apply autopolymerizing acrylic resin
N.B : midline fracture of mandibular arch requires repairing the labial flange

4. MATERIALS USED Autopolymerizing acrylic resin
(lack of strength, porosity &discoloration)
Heat cured acrylic resin
(risk of warpage)
