Suitable for SG and OC applications


A 1.7mm auxiliary modeling element (#450 000 73) is placed into a VKS paralleling mandrel and is waxed to the coping using a surveyor. The modeling element creates a 0.5mm larger receptacle to accommodate the cement used to bond in the threaded sleeve.	After wax has been applied around the auxiliary modeling element, it is carefully removed. Note: a vertical guide plane is created by applying wax directly onto the paralleling mandrel while waxing-in the modeling element.	Completed wax-up and ready to sprue for casting.

Lingual arm shoulder rest and groove are redefined and castings are finished as usual	Porcelain work is finished and metal areas are polished. Note: sandblast the hole lightly to remove any excess porcelain material.	1.7mm titanium threaded sleeve, stud-head screw and screwdriver. *WARNING: Screwdriver is designed to break before screw head to avoid over torquing and breakage at the ball platform where the screwdriver engages.

Use high quality anaerobic cement and apply it evenly into the hole created by the auxiliary modeling element. NOTE: Make sure to insulate with separating medium any areas where bonding cement is not desired such as, the model, paralleling mandrel, etc.	Use the surveyor to insert the ball screw/threaded sleeve assembly into the receptacle coated with cement and allow it to set. Using the surveyor will ensure that the attachment is set absolutely parallel.	After the cement has set, release the mandrel from the attachment and inspect. At this time any excess cement can be picked off using a scalpel and fabrication of the RPD can begin.
