In this article, Harmeet Grewal tells us how the 2A0 clamp made the impossible possible.

"This patient has very severe generalised wear and needs comprehensive treatment, but due to finances couldn't stretch to this. The patient had already ground down a premolar leading to exposure. I wanted to avoid a repeat of this situation, so decided to overlay with direct composite. Trying to restore this last standing tooth would have been a nightmare - placing a clamp and then matrix would have been too tricky; this is where the Hallerklammer 2A0 is a game changer for me...

Step 1. Clamp the 6 and isolate to the 3

Step 2. Restore the 5

Step 3. Remove the clamp on the 6

Step 4. Place an automatrix around the 6 and restore

The unique design of this clamp kept the dam in place, allowing me to execute step 4

This case is by no means the best aesthetic result and there are many things that could be improved, however it has bought the patient some time. This presented as an extremely awkward case that became much easier with the Hallerklammer 2A0. I couldn’t have restored the tooth adequately without it and I am so glad to have this as part of my armamentarium. I would recommend this clamp to everybody, especially those practicing adhesive dentistry under rubber dam."

Why the 2A0?

  • Retracts rubber dam for better access to 6s and 7s
  • Enables restorations of 7s under rubber dam without affecting matrix placement
  • The HallerKlammer can be used to hold saliva ejector and cotton wool rolls - helping to retract the tongue and cheek, thus reducing moisture contamination


Buy the HallerKlammer


"My HallerKlammers are an essential 'Get Out Of Jail Free' option in my armoury. For rubber dam retraction and accessing distal units in the arch or sextant, or holding a saliva ejector in place for tongue retraction, they help me ensure a moisture-free field in even the most awkward situations and smallest mouths. Now that I have them, I couldn't work without them" - Zak Kara GDP
