Non-Engaging Impression Coping Technique, cont'd
Sterngold | ERA® Attachment Systems
Using an indelible pen, mark a vertical line across the juncture between the implant abutment base and the ERA ® Micro Female, wherever space allows. Remove the ERA ® Females from the bases.
Add a small quantity of Resiment Ready-Mix cement into the socket of the base. Also, apply a small amount of cement to the button on the bottom of the ERA ® Female. Too much cement may make it difficult to completely snap the ERA ® Female into the base.
Snap the ERA ® Micro Female into the base, aligning the two halves of the mark. Clean up any excess cement.
The doctor will receive all of the abutments, being careful to identify each abutments position. Models are used to illustrate procedures in the mouth.
Each abutment is screwed into its appropriate implant and hand tightened, using the ERA ® Micro Socket and Thumb Knob.
Next, each abutment is torqued to 35 Ncm, using the ERA ® Micro Socket and a a torque wrench that will accommodate a 4mm square driver.
The remaining stepsmay be performed directly in themouth or on themodel.
Snap a Black Fabricating Male or a Metal Jacket with Black Male onto each abutment.
Small pieces of thin rubber dam are very effective at blocking out any exposed abutment surface. The rubber dam helps to prevent composite or acrylic from locking into any undercuts. Or the white block out spacers, packaged with Metal Jackets, may be used to block out undercuts.
Using a Round Bur, prepare a recess in the denture over each Metal Jacket. The denture should not touch the males or it will not be seated properly on the tissue. A lingual window may be formed into each recess.
Use SternVantage ® Varnish to prime the recesses over the Metal Jackets and light cure.
Add composite or acrylic over the top and sides of the Metal Jackets. Sterngold’s EZ PickUp ® material is recommended.
Place additional resin in the recesses of the overdenture and seat the prosthesis into the mouth.
