An open-ended wrench is a type of dental wrench that has a U-shaped end. The neck of the wrench is tilted forward at roughly a 45-degree angle to allow more access to the oral cavity, particularly the back teeth, and also to make the surgeon’s job a little easier. However, some straight-necked open-ended wrenches are available and which to use depends on the type of dental work needing to be done and the surgeon’s preference. Its unique design allows the implant surgeon to hold the mount in place while attaching it to implants with screw-type ends. In most cases, it’s used with external hex connection dental implants. Some open-ended wrenches have a handle on the bottom, while others are designed to have an open-end wrench on either side of the tool and to be held in the middle of the tool. An open-ended wrench is an essential part of the dental implantologist’s toolbox, along with torque wrenches, spring wrenches, ratchet wrenches, and more.
