Purpose:
Persistency of deciduous upper incisors or primary shortage of space can lead to an reclination of permanent teeth or to pseudoprognathism with a class III relationship of the front teeth.

Material/Methods:
The acrylic inclined plane is easy to produce and fixed on the lower incisors with GIC as a semi-permanent non-compliance device. The retrusive and inclined upper incisor gets in contact to the IP when the patient starts the chewing process and slides down and forward. The angle of the inclined plane should be about 65° - 75 ° to the occlusal plane. Due to the protrusion of the incisor, the upper edge of the plane has to be adjusted when it gets in contact to the palatal tissue.

For retention a removable retainer with protrusion springs for the upper incisors and Eschler-arch for the lower incisors is used.

Results:
Generally a malocclusion is unlocked in an average treatment time of 1-3 weeks. In this case the treatment time was 14 days and there was e.g. a significant change of SNA, upper incisor-angle and upper lip profile.
For retention a removable retainer with protrusion springs for the upper incisors and Eschler-arch for the lower incisors is used.

Conclusion:
These malocclusions can be corrected speedily in an easy way. Using the IP in early treatment is a very save, quick, cheap, robust and intermediate device without any wires, braces or occlusal bite-planes. The IP causes no trauma and is usually well accepted by the young patient.
