Broken Screw: help identifying implant?

Send to implant direct. They will identify and might carry parts depending on what it is.

The implant head has suffered hoop failure. This is a dead implant; remove it.

You can try "whatimplantisthat.com/" and compare pictures. However, I would judge this won't be a big help. If you look carefully at the implant platform, the top appears to be flowered out! I think the top lip of the implant is fractured ... which takes you down a completely different path!.

Wow. This a very challenging case and unfortunately a new screw is not going to help. It looks like the implant is fractured in addition to #3 being in the sinus and a failing lower arch. I would put the brakes on ordering parts and sit down for a heart to heart with this patient. Best of luck doc!!

Right...i didnt look very carefully. Montana is correct. Must be removed as their is a fracture at crest of implant. What connection is it??

Pretty sure that is a zimmer screw vent type implant. Out of all the implant systems, those implant tops fracture the most. Not that often but enough to drive you nuts. This implant needs to be removed.

Doesn't look like you can be restoring the fractured implant. Crestal bone loss and fractured implant head looks like typical overload case with cantilever forces we have been lectured about for the past years. Patient says 5-8years and you say his restoring practice is long gone. From experience of patient recollection perhaps a 2x increase in the timescale might be nearer to the truth! It could be an old corevent implant body but now your case has turned into a more comprehensive rehab. with failing teeth, occlusal schemes etc etc to plan for. Implant direct is a great source for this case but you can always make copings for the remianing four implants to incorporate then into a restored arch without getting too involved in components.

The one that is fractured is not a tapered screw vent because there is no vent in the apical portion. Maybe it is an old Nobel trilobe. These would fracture sometimes on the narrow diameters because of the very thin walls at the top and the commercially pure titanium . It should be easy to see just by looking down on top of the connection. In any case it doesn't really matter because it needs to be taken out

Remove the flowered implant and place a new implant in #10's (?) location, then remove the crown from #7's spot and make a bridge

The platform has flowered. You can put the implant to sleep and work around it one way or another. You can remove the implant. You can remove the screw and splayed portion of the platform. Then fabricate a pattern (direct or indirect and cement the post and core with Panavia cenent and restore as with conventional C&B. You could do nothing and worth around the implant. Do remove the sharp and irregular surfaces. Hope this helps.

Due to fracture you might bury the implant or remove it. Since the two remaining teeth are also hopeless, extract and replace with implants and a full upper arch implant supported bridge to be given might be the choice.
