How to remove a Ti-Base that is stuck in the implant chamber? The crown became loose so I took it off but I can’t remove the Ti-Base. This system doesn’t come up with the extractors for such situation. I read about applying endo ice onto the Ti-Base to shrink it a little and thus making it loose or unscrewing the screw and tilting the screwdriver back and forth inside the Ti-Base. Is converting the crown to a cemented one also an option in such a situation? I would be grateful for any tips
Knowing the brand of the implant would be helpful. For example, if it is a Zimmer fixture with a genuine Zimmer Ti-Base then you will need a specialized abutment removal tool which is included in the surgery kit. This is necessary because Zimmer has a friction fit in addition to the internal hex and the abutments will cold weld as long as it is not a cheap aftermarket clone. I am sure other companies have similar mechanisms built into their connection but knowing this I would think it is important to know the manufacturer of the product just in case you are dealing with a well designed connection.
I have no experience with any of these outfits so I can’t speak about the intimacy of their connection but if you take a deep dive into the mechanics of this particular product then you might discover a similar mechanism as what Zimmer has which will explain the difficulty you are having getting the Ti Base off. Just to be clear I have no idea as I have never seen an Axiom Anthology product but it might have a well engineered connection that likes to hold on and it might be a simple tool to help facilitate the removal.
Tap the TiBase laterally (90 degrees) a couple of times with a mallet and elevator / periotome or chisel with moderate force and them tap it again from the other side to see if it will losen up.
Gentlemen, I managed to do it. I unscrewed the screw and tapped the Ti-Base a couple of times from different angles with a mirror handle. I also used the screwdriver counterclockwise and a scaler . It finally loosened and I was able to pull it out. Thank you for your suggestions.
