Thank you for the great concise explanation! If we are doing a three unit screw retained implant bridge, it is possible to have one engaging abutment and one non-engaging abutment or does both abutments must be non-engaging?

@OBrienDentalLab 3 жыл бұрын

Yes! Most of the time that will work except in situations of extreme divergence between implants.

Thank you for an excellent video series. At 2:09 you show a non-engaging UCLA abutment for a single unit crown. Should this be an engaging UCLA abutment?

@OBrienDentalLab 3 жыл бұрын

Yes, good eye! Those crown images were being used to make the point that those are the only two types of restoration that can be made with UCLA abutments in general (both engaging & non-engaging). Given that I was talking about the availability of non-engaging parts and had the non-engaging abutment on screen, we should have used images of bridges instead - an oversight on my part!

Thank you for the infirmation. Just confused about non engaging abutments and multi unit abutments. For screw retained bridges, when should we use multi unit and when non engaging?

@mmwosu Жыл бұрын

MUA’s are used for making angle corrections across multiple implants for a full-arch prosthesis. This is an entirely different restorative situation than a 2, 3 or 4 unit implant-supported bridge that exists entirely in one quadrant and where the implants aren’t greatly divergent from each other

alex do you have any experince with pure conometric implants(example bicon). If yes could give some lab. tips ?

@EL-yi6df 4 ай бұрын

How do you relate the pure conical, the indexed conical, and the internal hex connections to the engaging and non-engaging abutments? Thank you.

@mwaisr 2 жыл бұрын

What do you think of laboratories using engaging custom abutments for screw retained zirconia bridges. They made the abutments non engaging at the time the bridges are finished and ready for cementing by cutting off the hex of the abutments. Is that acceptable? If not, why is that?

@OBrienDentalLab 2 жыл бұрын

This is not something we recommend. Implant abutments are class II medical devices and the FDA prohibits labs from altering the interface.

@@OBrienDentalLab I had a case that came to me from a practice in another state where the previous restoring dentist had done this chairside. It was a single unit (#30), and patient’s complaint was naturally that the old dentist was always having to re-tighten his implant crown. It took me a little while to figure out what the old guy had done, I presume because he ran into trouble with orientation during delivery (I would guess an improperly seated impression coping was the original culprit, the patient’s recall of the events seemed to match this type of scenario). Ended up making a new screw-retained restoration, the patient was very happy and is still with me today. A good reminder of why these features exist in the first place, and why messing with them is a bad idea

is it necessary to use non engaging abutments in screw retained prosthesis?

@OBrienDentalLab 3 ай бұрын

Only when there are two or more implants that are being splinted together. In that situation, at least one of the abutments should be non-engaging to ensure a passive fit.
