4/14


Extreme protrusion of the maxillary and mandibular anterior teeth. Cuspids and molars

are in a class I relationship.

Moderate crowding in both arches. Slight expansion of the first molars in both

arches needed.

The initial archwires of .016 nickel titanium in both arches are utilized to correct rotations and correct the faciallingual plane of all teeth. Both archwires are inserted in the pre-adjusted slots with the exception of the

mandibular six anterior teeth where the archwire is inserted into the interactive slots. This will allow the six

mandibular teeth to be tipped distally to establish a good overbite relationship between the arches in the

anterior. Light class I elastics in the mandible was employed. The retraction of the anterior teeth continued with

.016 steel archwires with bi-lateral gable bends between the cuspids and the bicuspids. Each archwire was

inserted in the interactive slots in the anterior teeth and for better anchorage in the pre-adjusted slot in the

posterior teeth in both arches.

Once all extraction spaces were closed, the cuspids had a distal tip. To maintain the bite open a .016

steel VS (vertrical stablization)archwire with bi-lateral gable bends was inserted into the interactive

slots of each arch. Also, to up-right the cuspids a .018 x .020 nickel titanium UA (universal auxillary)

archwire was inserted into the pre-adjusted slots of each arch

Continuation of the alignment and up-righting of the teeth in both arches with

the same configuration of archwires.

Occlusal views to show archform and space closure. No attachments on second

molars. First molars and second bicuspids only were used for posterior anchorage.

The .018 steel archwires were removed from the interactive slots in both arches.

The .018 x .025 nickel titanium remains to finish the case.

Continuation of finishing with the .018 x .025 nickel titanium

archwires.
