  • Closed tray impression technique: no hole cut into trayOpen tray technique: hole cut into tray so that impression coping can poke throughUse PLASTIC trays!
  • Hiossen recommends when it’s 22 degrees or more (11 degree each) then use non-hex…
  • Have patient bite a cotton roll or 2X2 to seat prosthesis all the way down and to “stretch” the gums, especially cement-retained
  • Unless it is a FM restoration, the majority of the occlusion should be on natural teeth. Implant occlusion should be out of occlusion by the thickness of articular paper, or the thickness of the PDL
  • Be sure to use soft liner with FD or PD monthly with at least 3mm thickness of the soft liner

    1. 1. The ABCs of Implant Prosthodontics: A Step by Step Idiot’s Guide For A Successful Restorative Outcome
    2. 2. Impressions
    3. 3. Closed Tray Impression TechniquesAdvantages Easier, Impression coping for closed tray are usually shorter, making it easier for posterior areas and for patients with limited mouth opening Less time for impression preparation: cutting holes in the impression tray usually not needed Impression cap type techniques can be “idiot proof” Possible problems with: Snappy, EZ, and other similar systems
    4. 4. Closed Tray Impression TechniquesDisadvantages Less accurate with multiple units Some implant systems require more clearance than other implant systems, therefore may still necessitate cutting holes in the impression tray as with the open tray technique, and as a result, may be less accurate depending upon several factors Positional timing error, depending upon the impression coping design
    5. 5. Open Tray Impression TechniquesIndications Usually used for multiple units Use non hex (non engaging) impression copings if implants are not in alignmentSplint together Durelay Wire/DurelayAlignment jig/pick-up impressionAdvantages More accurate for multi units
    6. 6. Open Tray Impression TechniquesDisadvantages More impression preparation and impression time Test fitting impression copings and cutting holes for the impression copings Additional time to “unlock” the impression copings Adequate mouth opening required More possibility for gagging
    7. 7. Closed Tray Technique for Bridges?As the distance between the impression copings increase, so do the inaccuraciesDo not use Putty, more accurate to use regular/light bodied PVS or monophaseWait 30 minutes before pouring up the models to maximize the rebound effect of theimpression material
