[QUOTE="JohnWilson, post: 18009, member: 213"] In the picture you provided is the second unit a screw retained gold crown?? Going over a screw retained crown is a bit more difficult because of contours. When we do those types of jigs we use Acrylic lined with Versacryl (resilient material i.e. flexes) Often times when doing multiple units when engaging parts are used the Dr will have to load the jig up with one unit, screw it down, remove the jig, re seat additional unit/s and repeat. Light cure material works perfectly on most single units, but I choose to use baseplate material over the flowible type. Seems it adapts a bit better to the abutment. Retention of the abutment in the jig is based on many things but most importantly is abutment design (How parallel the walls of the abutment are and having at least one flat side so the abutment does not rotate in the jig) Adding friction to the polished surface (sandblast)will help as well. A dab of Vaseline works wonders in the operatory as well. The screw hole is the most important part this is what allows the Dr to tighten the abutment where it belongs. Just make sure when the jig is made that the screw has the ability to go through the top of the jig with out binding. Let me know if you need any further details. [/QUOTE]
