In this video we're showing you an exciting product that opens up a lot of possibilities for fabricating screw retained restorations.
Non-engaging abutments are required for splinted screw retained restorations, but it's extremely rare for them to also have an option to angle the access hole. Most of the options available are just stock bases, so we have no control over the emergence profile or height of the abutment.
There is however a company that does offer non-engaging custom abutments for all of the major implant systems. And better yet, we can design them with angled screw channels.
The company is TruAbutment, and their non-engaging angled screw channel custom abutments are a lifesaver for these cases that used to be very limited in restorative options.
We really like these better than using a stock base because:
1. We have much better control over the subgingival contours of the abutment
2. We can build the abutment up to be more substantial than a titanium base
3. We can typically make the abutments much taller than what we would get with a titanium base.
These still won't work in every situation. For instance, if the implants have a really high degree of divergence, the splinted abutments might not seat passively in to the implants. In those situations we need to make custom abutments that are designed to be parallel to each other and seated to the implants separately for use with a cement retained bridge.
It's important to note that these do require a specific angled screwdriver. But, another thing that is really cool about TruAbutment is that they include a single use driver tip with every angled screw channel abutment.
