Directions |
| MTL-V Primer
(Parkell) |
Clean crown surface with alcohol gauze. Rinse and air dry. Ultrasonically clean crown in water. Air dry.Sandblast crown interface (Al2O3/50 µ/35 psi/10 sec)Using a micro brush, apply 2 coats ofMTL-V Primer.Allow surface to dry for 60 sec. Cement as per experimental group requirements (LAVA crowns only) |
| Etch-Free Silane Primer
(Parkell)
|
Clean crown surface with alcohol gauze. Rinse and air dry. Ultrasonically clean crown in water. Air dry.Sandblast crown interface (Al2O3/50 µ/35 psi/10 sec) Mix a drop of each Etch-Free bottle A+B in a 1:1 ratio for 15 sec. Apply a thin layer of the primer to the crown interface. Air dry for 10 sec. Apply a second layer of the primer and air dry for 10 sec. Cement as per experimental group requirements . |
| C& B Metabond
Adhesive Cement
(Parkell)
|
Clean the crown preparation with alcohol gauze. Rinse and air dry. Ultrasonically clean the preparation in water. Air dry. Etch enamel surfaces for 30 seconds with a micro brush saturated with the orange Enamel Etchant. Dab the enamel surface with the brush. Do not scrub it. Avoid overruns onto the dentin. Rinse off the Enamel Etchant and air dry. Apply the green Dentin-Activator (either gel or liquid) to dentin for 10 seconds. Thoroughly rinse off the activator and dry the tooth with a gentle burst of air. Avoid over drying and desiccation.
Remove the ceramic mixing dish from the freezer. Holding the bottle vertically, dispense 4 drops of C&B-Metabond Quick base (blue cap) into one well of the chilled ceramic mixing dish.
Holding the syringe vertically, add one drop of catalyst to the base liquid and stir gently for several seconds (no more than 5 seconds). Paint both tooth and casting with the mixed liquid. Add 2 level scoops powder to the mixed liquid (4 drops of base and 1 drop of catalyst).Gently stir powder and liquid for 5 seconds to create creamy cement. Apply the cement to the restoration, and seat it as quickly as possible. Apply a drop of base only (blue cap) to a cotton pellet and wipe away excess cement. Apply weight and hold ceramic crown until the material has completely set. (5-6 minutes). |
| SEcureDental
Primer
(Parkell) |
Clean the crown preparation with alcohol gaze. Rinse and air dry. Ultrasonically clean a preparation. Air dry. Dispense several drops of SEcure Self-Etching Primer into the well, and brush one generous coat onto the preparation. Leave for 10-20 seconds and then gently air dry the liquid for 5 seconds. Do not light cure. |
| SEcure
Resin Cement
(Parkell) |
After the priming of the tooth surface, remove the cap or previous mixing tip from the SEcure Adhesive Resin Cement syringe and bleed enough out to assure that the cement in both barrels is flush with the front edge of the orifices of the syringe. Attach a 4:1 mixing tip, bleed a small amount of cement onto pad, and dispense directly into restoration. Fully seat restoration onto the preparation and allow excess to extrude from all margins. Place weight and hold restoration in place, and remove gross excess cement while it is soft using glycerin-soaked cotton pellets. Wait 5 minutes for a complete self-cure before the final cleanup and occlusal adjustment. The final cure time can be shortened for translucent restorations with a 20 second exposure from four directions (mesial, distal, buccal and lingual) with any dental curing light. |
| Brush & Bond
Bonding System
(Parkell) |
Clean crown preparation with alcohol gauze. Rinse and air dry. Ultrasonically clean the preparation in water. Air dry. Dispense 1-3 drops of BRUSH&BOND Liquid into the mixing well and stir for 2 seconds with an “Activator Microbrush” Activated B & B liquid. The mixing well should be covered and used within 3 minutes. Apply activated liquid onto prepared tooth surfaces and keep moist with liquid for 20 seconds. Evaporate the B & B solvents with a gentle air stream for 10 seconds. Light-cure the remaining B & B resin with LED curing light for 10 sec. |
| HyperFIL DC
Resin Cement
(Parkell)
|
After priming the tooth and crown surface, place the HyperFIL cartridge into the dispensing gun. Bleed a small amount of material onto a pad to assure that material is flowing from both orifices. Place the intraoral tip into the bottom of the preparation to avoidtrapping air and slowly express the composite as you withdraw the tip. Keep the tip immersed in the HyperFIL until the prep is adequately filled to eliminate air entrapment. Fully seat restoration onto the preparation and allow excess to extrude from all margins, remove the excess. Light cure the surface for at least 40 seconds with an LED light. |
| RelyXTemp NE
TemporaryCement
(3M ESPE) |
Clean the crown preparation and the intaglio surface of the crown with alcohol gaze. Rinse and air dry. Ultrasonically clean the preparation and the crown. Air dry. Dispense two equal lengths of base paste and catalyst on a mixing pad. Use a plastic spatula to thoroughly mix the paste for 30 seconds until a homogeneous consistency is created. By overdosing the catalyst, the bonding strength is increased and the working time is prolonged. Apply a thin layer of cement on the surface to be cemented, and place the dental restoration with slight pressure. Apply weight, remove excess and wait 4 minutes to set. |
