No, it is not. It has durability of other general orthodontic appliance (about 2 years) when cared well.
The degree of protrusion is adjusted as push stick of upper jaw pushes the lower jammed jaw into the front, and here, if you put the key in the hole of metal adjusting screw of push stick of upper jaw and turn it once (1/4 rotation), the length of push stick of upper jaw is extended by 0.2mm, so if you repeat it 5 times, 1mm is extended. As you follow this step, the degree of lower jaw protrusion increases.
Plates of upper jaw and lower jaw occlusion meet each other closing the mouth until the point where mouth cannot be closed anymore. Here, occluding part by jammed jaw between upper and lower jaw become the right location.
The inner side of the appliance is soft, while the outer side is hard having relation between inner elastic material and wearing sensation and retentivity control. When retentivity is decreased, we compensate in the way that ball clasp is added since soft part is impossible to be repaired.
