Sledgehammer Mouldable Self Cure Acrylic. (Funny name, great acrylic) Occasionally something comes along which actually makes life easier for the technician. Sledgehammer self cure acrylic is one of these. Sledgehammer self cure acrylic, available in original (pink veined) light fiber plus and clear, is specifically formulated for moulding techniques, unlike conventional self cure acrylics which form an outer crust while remaining runny beneath the crust. When mixed, Sledgehammer self cure goes through the same stages as heat cure acrylics. From sandy stage to cobweb, to doughy to snappy stage. This feature alone allows the technician to mould the Sledgehammer self cure, allowing for easy and accurate repairs. Imagine repairs, additions and relines without the acrylic slumping or running into and onto areas where we don’t want it to go. No more trying to stop the self cure acrylic from running all over the palate and welling up into the middle of the palate, when repairing a mid line fracture, which of course requires more time to trim and polish. All in all Sledgehammer self cure offers us greater control without sacrificing accuracy. With practice one could form the palatal extension directly onto the model. Did anyone mention bubbles? Prepare denture in the usual manner. Mix Sledgehammer self-cure acrylic. Wait until acrylic reaches putty state (5-10 min). Roll into sausage shape. Rinse the denture surface with monomer. Press the Sledgehammer roll into the repair area to within 5mm of the teeth. Mix some more Sledgehammer and pour into the remaining area through to labial. Process in the usual manner - 10-15min @ 50-60 o C in hydroflask. MIDLINE FRACTURE REPAIR TECHNIQUE 1 - Broken Flange 2 - Clean & roughen repair area 3 - Mix Sledgehammer S/C. When ready to handle (doughy stage), prime the repair area with monomer and apply the Sledghammer S/C to repair. Trim with a clean, sharp scalpel 4 - Smooth over with monomer and place in hydroflask Maintain Palatal thickness Reduce waste of material Avoid bubbles Save time Gain control REPAIR BROKEN FLANGE
