5- Selection and adjustment of stock tray

Selection of the stock tray: Check tray size in relation to arch size. Check flange extension. Over-extension of stock tray flanges should be adjusted during border molding. Adjustment of the stock tray: Adjustment done by bending overextended flanges using a plier or by cutting it using a scissor. Smoothing the sharp cutting edges of the flange borders using a carbide bur. Open a space for frenal attachments to prevent its injury and to allow proper registration in the impression. Eliminate all sharp edges that may injure the patient mucosa. Adjustment of the tray handle to allow the freedom of lip movement. #step_by_step_complete_denture_making
