ERA® RV Partial Males Green (5)
ERA RV Partial Males Green (5)
Actual product dimensions and minimum space requirements needed for sizing can be viewed in the Instructions for Use .
Males easily changed without use of autopolymerizing acrylic.
Fixation: Male - retained directly in processed denture acrylic or an ERA® Metal Jacket.
Black fabrication male and eight color coded males for a consistent level of retention.
From smallest button diameter to largest button diameter they are as follows..white, orange, blue, grey, yellow, red, green and purple.
FAQ’s
1. What would be the best way to describe an ERA? Extracoronal semi-precision attachment/Universal hinge with vertical resiliency.
2. What is the biggest contradiction about an ERA? The biggest contradiction is that the ERA is not appropriate for case designs requiring rigidity in function.
3. How can the female be placed closer to the die? If necessary, some or all of the contoured retention plate may be removed to better position the female in the wax.
4. Which alloys should be used with the female of the ERA? Cast using a hard alloy. Minimum Vickers hardness of 200 and at least 85,000 psi ultimate tensile strength. Appropriate choices are Pegasus ceramic alloy and Sterngold 100 crown and bridge alloy for yellow gold castings.
5. What are the levels of retention of the ERA Males? Black fabrication male and eight color coded males offer a consistent level of retention. From smallest button diameter to largest button diameter they are as follows: white, orange, blue, grey, yellow, red, green and purple. Two Extra Oversized Males for greater retention in problem cases - yellow has a larger button than the grey; red has a larger button than the yellow. Two Extra-Extra Oversized males for greater retention in problem cases – green has a larger button than the red; purple has a larger button than the green, (green and purple are only available for the ERA-RV partial denture attachments.)
Features and Benefits
Nylon male, plastic pattern female.
Males easily changed without use of auto-polymerizing acrylic
Standard and reduced vertical (ERA®-RV) size males. Both size males fit the same female.
