Unable to seat Hiossen Impression Coping: Recommendations?

Hello. I place these at an office. Make sure your not using ‘M’ impression coping, for mini 3.5 implant.

You probably need to use the bone profiler. You can get them from Hiossen. This will eliminate your problems.

I hope you took a radiograph to verify seating which you did not post. If not, that is the second thing you need to do when attempting to seat impression posts or healing abutments. The first is to verify you have the correct component(part). Also be prepared when exposing the implant and have the bone profiler ready as was suggested. It should never take you that long to seat either of those components.

Please post an IOPAR to enable a clear view. Also if it’s sub crestal, it is likely that some bone is interfering with the taper of the impression post placement. Try a cement retained restoration instead.

Please post photos and xrays...what you are stating makes little sense......sorry!!!!

I use Hiossen as well. What size impression coping are you using? If you are using 5mm it may binding against the gingiva. Instead use 4 x 14 (the longer) coping. It should work since you said 4x5HA seats. Good luck!

In addition check to see if any gingiva has grown on top of implant margin thus preventing seating. Maybe the HA was not seated completely due to bone impingement or HA became loose.

Hi,first things first hope you are using a new impression post.Many of us including me sometimes use copings more than once and old ones sometimes don't fit.So try a new piece.2nd thing is place an abutment and see if it still rocks.If it does then you may have damaged the implant while removing the bone around it(which is hard to fix).If the abutment fits then that means the coping isn't seating as it's flare must be catching on either some bone or gingiva.Hope I helped.Gopd luck

The impression transfer is being prevented from being seated by bone surrounding the I/A interface. You will need to anesthetize and use the bone profiler instruments. You will need to use the 5.5 mm profiler. Be sure to use no more than 1k RPM with plenty of chilled sterile saline irrigation.

Bone profiler to the rescue! Typically if the implant is subcrestal when uncovered I will the Hiossen bone profiler that corresponds to the implant diameter. This will prevent problems when placing the impression pin a few weeks later.

Bone profiler will do the trick definitely. Pitiful hacks on emergency situation: If you need to wait for some time to get the profiler, and if the patient cannot wait for several reasons, try using countersink drill. Start with slightly smaller diametered sink drill to put it in the internal connection part of the fixture. The countersink drill of Hiossen has non cutting surface on tip, which does no harm on fixture when drilled. Put the drill deep around the fixture platform and drill it with 100 rpm, no irrigation. Rotate and stir the handpiece and drill as if you manipulate joystick in old arcade. That will enable you to cut crestal bones on the platform. If can see ground bone on the sink drill cutting edge, try with larger diameter.

Take an xray. You have bone grown above your implant that isnt letting your components fit all the way in.

Occasionally bone will grow over the platform edges or thick KT will impinge on placement. Bone can be tough to remove without dinging up the periphery and compromising a sealed seating. I don’t use these but make sure the size and abutment accommodate each other, as well as screw size. I use Nobel and there are differences in the tapered and active components. Every case is different. Please post a pic. Happy implanting.
