Klammt appliance

Klammt appliances

They have two lateral acrylic blocks resting on the canine teeth, the lateral teeth are only touched on their oral surface. They have a Bimler labial arch at the top and bottom, with loop springs or split wire supports on the cingulum of the lower and upper front teeth. The two acrylate blocks are connected by Coffin springs.

Optionally, the loop springs can be split to make the device more elastic. Different acrylate extensions can be used, "acrylate without conductive surface" is a design where the part of the blocks in contact with the tooth surface is smooth, so that when the tooth is changed, the acrylate does not obstruct the closure of the lee way space. Diastema closure spring and tongue barrier placement is common. Pelottas can be made on the labial arches to support the lips.

Indications: A I ; A II; A III; cases, sagittal, vertical, and rotational deviations of the anterior teeth.

Activation: by activating the Coffin spring, the appliance is adjusted according to the expansion of the dental arch. Differential activation of the labial arches and the loop springs allows the anterior teeth to be moved, protrusion, retraction, rotation. By grinding the acrylate, we can control the movement of the teeth (eruption trough), and we can also grind the appliance extended into the interocclusal space according to Harvold.
