Bone Embedding Technique with Inhibited Pmma Monomer

Abstract
Unwashed inhibited thin and thick methyl methacrylate monomer was used for successful embedding of bone by increasing the quantity of benzoyl peroxide catalyst until the activity of the hydroquinone inhibitor was overwhelmed. Seven bones were embedded using 1, 2, 4, 6, 8, 10 or 12 g of benzoyl peroxide/100 ml of thick monomer. Two g/100 ml was found to be optimal. Higher concentrations resulted in uncontrolled polymerization while at 1 g/100 ml the solution remained liquid.
