Abstract EN
Objective.
To describe a clinical case with a severe mandibular crowding treated without extraction and showing a long-term outcome.
Methods.
A 14-year-old boy in permanent dentition showed a class I molar and cuspid relationship, a severe deep bite of 8 mm, a constricted V-shaped upper arch with moderate crowding, and a severe crowding of about 12 mm in the lower arch.
The panoramic X-ray showed an impacted upper right canine.
The treatment started with the placement of a transpalatal bar and 0.022×0.028 in standard edgewise appliances in the upper arch and a lip bumper bonded on the second lower molars.
Initial leveling of the teeth was accomplished with light Australian round wires.
Finishing was then performed with rectangular wires.
The phase with fixed appliances lasted 2 years and 9 months, and the patient was motivated and cooperative throughout the treatment, although with poor oral hygiene.
The patient was treated without extractions.
Results.
The space was gained with the first and second upper molar derotations using the transpalatal bar and the gingival lip bumper in the lower arch.
The upper right canine was well positioned, and the maxillary arch form was improved.
The severe lower crowding was completely corrected, and a good overbite was achieved.
Conclusion.
A conservative, nonextraction treatment approach for this patient with class I malocclusion with severe mandibular crowding was effective, and the results have remained stable after a long-term follow-up (10 years).
