Preparation: • Remove provisional restoration and all temporary cement residue. • Trial fit the restoration and clean thoroughly. Pretreatment of Tooth: • Use a pumice slurry, rinse, lightly dry. Do Not Overdry. Note: Please Follow the Instructions for Use. H2O2 should not be used. The use of substances such as desensitizers, disinfectants, astringents, and dentin sealants, etc., after final cleaning with pumice paste and water is not recommended. Their residues may have a detrimental effect on the bonding strength and setting reaction of the cement. Pretreatment of Restoration: See pretreatment recommendations table or instructions for use. Activation: • Insert capsule into Activator. • Press down handle completely and hold for 2-4 seconds. Mixing: • Insert activated capsule into mixing device (triturator/amalgamator). • Mix 10 seconds for 3M™ ESPE™ RotoMix™ Capsule Mixing Unit. • Mix 15 seconds at highest speed for other mixing devices. 1 2 3 4 3 of 4 15379_RelyXUnicem 10/31/06 10:39 AM Page 4 CEMENTATION TECHNIQUE RelyX ™ Unicem Self-Adhesive Universal Resin Cement Aplicap™ /Maxicap™ 5 6 7 8 4 of 4 Dispensing: • Remove capsule from mixing device and insert into Applier. • Open nozzle and dispense cement directly onto bonding surface of restoration or directly onto tooth surface for inlays and onlays. For posts and pins, do not use a Lentulo-Spiral. • Working time from start of mix: Aplicap 2:00 min. Maxicap 2:30 min. Placement: • Seat restoration and hold in place with light pressure. • Excess cement is best removed in the cement’s gel state with scaler or explorer. Tack cure excess with light for 2 seconds or allow to self-cure for 2–3 minutes from start of mix. • It is important to check occlusion after the cement is set so that the cement is not disrupted. Final Cure: • For translucent ceramic restorations, light-cure each surface for 20 seconds. • For all others, allow cement to self-cure Aplicap 5:00 min. from start of mix. Maxicap 6:00 min. from start of mix. Finish and Polish: • Insure all excess cement is removed. • Adjust occlusion. • Finish exposed surfaces using appropriate instrument and polishing paste. • Finish proximal surfaces using 3M™ ESPE™ Sof-Lex™ Discs and Strips. 3M ESPE Customer Care 1-800-634-2249 Please refer to instructions for more detailed information as well as precautionary and warranty information. 44-0007-4405-0 © 2006 3M
