must have taken so long to write that , I thank my friend.

or even superglue and paperclips,
That's a great idea , I always have difficult time trying to figure out if they will be removed together or not

They never heard of it ,
let me ask you something : isn't a non-engaging abutment simply just an abutment without a hex ?
Yes, you should be able to freely spin it. The hex is so the abutment does not rotate when it is a single unit. With 2+ abutments splinted by a bridge or bar you do not need that anti rotation because the prosthesis cannot rotate. A hex can work against you with multiple connected implants.

May I ask for, maybe rephrasing this sentence, I couldn't get it, what do you mean ?

Let's say you got a screw retained bridge and one the screws got lose...if your bridge has engaging interfaces the loose end will exert tension on the other implant through pivoting, eventually leading to failure or fracture. In case of a non-engaging interface, there's no keying between the implant and the abutment, so the screw is the load bearing element, being weaker than the implant itself, will break or looses up before the implant could fail. Replacing a screw is more favorable than replacing an implant...

You're quite welcome. Did they come off and go on to the model in one piece?

Hi Adi, why don't you try to get the proper components from a different source, maybe order them from outside your country. Shipping will only take few days.
Get on google and find a supplier. Even a milling centre should be able to help you, they stock Ti bases for sure .

He's in Syria. Probably not as easy to outsource or find what is needed.

I do understand that, as long there is some mail service working, should not be too difficult to buy from anywhere.

Looks good,
I would get a metal margin (porcelain Junction) at the base of the abutments.. just below the tissue.
this is why it's important to use tissue replication material as well... you can sculpt the tissue and lay the wax in

Very well , it's clear now, thanks.
Just two follow-up questions :
_ should all the abutments used in one bridge be either non-engaging or engaging? Or it could be multiple?
_ can the surgeon remove a broken screw if it broke in the implant?

All bridges/bars should be non engaging. Only single units engaging.

Say what?!!!! remove the hex ?!!! is that allowable ?
That's a life saver if it is allowable .

Yes, go ahead...just be careful with the rest of the interface...

Its easy to remove, they are designed to become loose if the head breaks off, they don't bottom out in the tread...

This is like the blind leading the blind...if you are making a fixture level bridge you need non engaging castable waxing sleeves....looking at the the angle of the molar...you may not be able to do that. If it was my case I would be placing the abutment you choose (blue) and a straight abutment in the green. I would not be using impression pieces for final abutments...some are not titanium.
I would then wax and cast a cemented bridge....have the dentist trying the frame and then apply your porcelain. When a screw breaks it is not always easy to remove...also different screws are often used for non engaging bridge or bars....they are thicker due to the increased load they have to carry

It's easy to consider solutions incorrect when we can get anything we want shipped to us in 24hrs. He's in Syria, and it's not that easy, if possible at all to get many things needed for what we think we "need" in daily life. Much less implant parts. If you were not aware he's in Syria, my apologies, but he said when he asked for non-engaging they were not available. So we are trying to help him work with what he's got.

Any suggestions germane to the issue now that (I presume) you're done being insulting before reading the thread??

P.S. Excuse the rancor, but you hit a nerve by assuming without reading what's right in front of you.
