The large space between prepped tooth and adjacent on the typodont is what you usually don’t have in the real life. And that’s what makes it difficult to place the Garrison matrixes there.
There are 2 different matrix band placement instruments shown here. NiTin Garrison Band Forceps (NTG-DF6-8) which are more of a standard tweezer placement tool. Also, the Composi-Tight Matrix Forceps (BFA-1) which has a dedicated video on our channel. I recommend checking it out: th-cam.com/video/5bWtxzbmXrQ/w-d-xo.html. Both are Garrison products and can be found at garrisondental.com.
If you've placed it as far gingivally as possible, the ring shouldn't slip off the tooth. It has retention extensions on the bottom that grip below the infrabulge of the tooth and it's difficult to get them to pop off without removing them with the forcep, as long as it's placed correctly. If it does pop off the tooth, place the ring again, making sure it's seated as far gingivally as possible, then once placed, wiggle the back of the ring loop to make sure it's secure.

Are the wedges autoclavable?
Wedges, along with matrix bands, are single patient use.
