The Lizat appliance (Lip bumper and Frozat) according to Kinzinger
Elements:
Lingual arch and anterior spring 1.0 mm remaloy®, lip bumper 1.0 mm
Function:
Molar distalisation with simultaneous anchorage through the lower lip
Description:
The lip bumper is mainly used to enhance anchorage, but can also support the distalisation of the molars
The lingual Frozat appliance is bent as usual. Special attention should be paid to avoid hindering the lingual frenum when determining the position of the lingual arch.
Buccal tubes are soldered onto the molar bands to receive the individually made lip bumper. This lip bumper has a wider and thicker acrylic shield than the preformed ones.
The finished lip bumper has to be inserted easily and without tension into the corresponding buccal tubes by the patient.
