i use a sideless triple tray, take a preop with discus vanilla bite, high durometer value. after prepping we make the temp in the same tray. if there are any areas of minimal reduction i might modify the intaglio :) of the vanilla bite to make a thicker temp in an area, (such as MB root area) and/or grind out an area where tooth was missing structure, such as a broken cusp.

we usually get a near-perfect temp from a luxatemp-type material, check its fit and then prep the tray for final impression. in the lab i take a 557 bur and make an entry hole through the bite material, usually into the MB aspect, at an angle i can access when back in the mouth. i often open the entrance a bit to allow the standard syringe tip (generally trimmed/opened about half of its curved length) to get into the entry port. i also place a distal exit port for the excess syringeable material to escape. I take a round acrylic cutting ball and run it a bit around the cervical area on the buccal and lingual, to give a bit more thickness/strength for the light body. i also run a couple of grooves out from the prep area into a thickness of bite material, usually on the palatal, for extra retention. all of this takes less time than it did to type.

the tray is then washed and/or scrubbed with alcohol and thoroughly dried. back in the mouth in firm closure, and then i inject the Parkell Mach 1 (or mach 2, i forget) into the entry hole with some pressure until it flows out the exit hole. bite for about 2 minutes, and i generally get a great impression. If i don't, i will take a quad impression and send it along with the triple tray. then of course, the lab needs to handle it correctly.

I had tried the H and H technique, but had issues with getting people to bite in the same place quickly, with pressure and time constraints, and i also was not comfortable trying to dry the prep area, etc. this other technique worked better for me especially in those constraints.

i hope this helps, i think you can probably go to Parkell website and access the articles that discussed this years ago. i find it fast and accurate, with temp, bite and final impression all in one.

regards, bill g
