A clamp release mechanism is provided. The clamp includes a body, a shaft slideably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. A locking component actuates between a locked position and an unlocked position. When in the locked position, the locking component biases the shaft to remain stationary with respect to the body. The clamp includes a securing component pivotally coupled to the locking component, and a biasing element that biases the securing components towards the shaft.

A handheld vise for dental crowns includes a vise block, an elongated handle extending from the vise block, a linear screw embedded in the vise block, and first and second jaws. The second jaw may be arcuate on a gripping surface thereof to conform to the shape of a dental crown. The handheld vise is sized for quickly and readily securing a dental crown such as a stainless-steel dental crown for use in pediatric dentistry. An elastomeric material may be used on the gripping surfaces of the vise. A radius of curvature of the gripping surface of the second jaw may be between about 25-35 mm. A height of the jaws may be between about 2-5 mm, and a distance between the first jaw and a vertex of the second jaw may range from about 3-10 mm. A method and kit for forming crowns including the handheld vise are disclosed.

A leveling system for a clamping device can include a base having a top, a bottom, and a plurality of sides; and a leveling knob positioned on one of the plurality of sides of the base and comprising a spring, a pin, and a knob connected at an outer end of the shaft. The spring can be compressible when the knob is pulled away from the base. In a locked configuration, the leveling knob can be at a neutral angle and in a home position with the pin positioned within the base. The pin can be removable from the base when the spring is compressed. The leveling knob can be twistable in at least one of clockwise and counterclockwise rotations when the pin is removed from the base.

A power vise including a body and a jaw connected to and extending from the vise body. The vise can also include an actuator extending at least partially through the jaw body, where the actuator can include a first end and a second end opposite the first end. The vise can include a moving jaw connected to the first end of the actuator. The vise can include a motor connected to the second end of the actuator, where the motor can be operable to move the actuator to move the moving jaw with respect to the fixed jaw, including a hammering or impacting function, and that such hammering or impacting can be performed after a predetermined delay. The vise can include a sensor configured to produce a signal based on a condition of the vise and to control the vise at least in part on using that signal.
