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.

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.
