Résumé
@#Crowding is the most common dental case worldwide. This case report describes the diagnosis and management of a 20-year-old woman with severe crowding, deep bite, and midline shifting. The patient presented with the chief complaint of crowding and an unaesthetic smile. Upon examination, the patient had Angle Class I Malocclusion. The severe crowding was treated comprehensively and successfully corrected using fixed orthodontic appliances and without extraction, only interproximal reduction (IPR).
Résumé
@#Class I malocclusions with severe crowding and tooth size discrepancies may be successfully treated orthodontically with extraction therapy, and co-management with other specialists. Correction of the discrepancies will optimize occlusal result (overjet, overbite, midline shift, and smile esthetics). This is a case of a 19-year-old male with severe crowding in upper and lower teeth and peg lateral incisor. The patient had malocclusion Class I. This case was treated comprehensively and successfully using fixed orthodontic appliances with extraction of four premolars, and veneer composite for peg lateral incisor with the help of a conservative dentist at the end of orthodontic treatment.

The mandibular premolar impactions account for nearly 24% of all the dental impactions including the third molars. The literatureregarding the impactions of mandibular premolars is very limited although they are considered as the third most commonimpactions after all the third molars and maxillary canines. This case report describes the treatment of a Class I malocclusionhaving severe crowding in both the upper and lower arches, buccally placed maxillary canines and impacted mandibular rightsecond premolar with an asymmetric treatment approach in a young growing patient.
Résumé
Cuando se presenta apiñamiento severo, en muchas ocasiones la ubicación que adoptan las estructuras dentarias dificultan el tratamiento, por lo cual se sugiere extracciones asimétricas para permitir de esta manera un tratamiento menos prolongado y con resultados satisfactorios. En este artículo se reporta un caso de biprotrusión dentaria tratado con extracciones de 4 premolares, en una paciente femenina de 20 años y 6 meses, Clase II esquelética, hiperdivergente, con un patrón dolicofacial, Clase III molar bilateral, Clase I canina bilateral, línea media superior coincidente e inferior 4 mm desviada a la izquierda, y no presenta hábitos. En los objetivos de tratamiento se planteó: extracciones asimétricas de primeros premolares superiores e inferiores, corregir el apiñamiento maxilar y mandibular, obtener líneas medias coincidentes, obtener la Clase I molar bilateral, mantener la Clase I canina bilateral. Se logró corregir el apiñamiento severo con una forma de arco adecuada.
In cases of severe crowding, many times the location of dental structures impede treatment, so asymmetrical extractions is suggested to allow a less prolonged treatment with satisfactory results. This article presents a case of dental extractions biprotrution treated with 4 premolars reported, a case of 20 years and 6 months old female patient, skeletal Class II, hyperdivergent, with bilateral dolichofacial pattern, molar Class III bilateral, canine Class I bilateral, upper midline coincident and lower midline 4mm left deviated, is reported and no habits. The goals of treatment are proposed: a symmetric extractions of first premolars upper and lower, correct the maxillary and mandibular crowding, achieve midlines, and obtain bilateral Class I molar and maintain bilateral Class I canine. It was possible to correct severe crowding with a suitable form of arch.

Las causas de las discrepancias transversales del maxilar superior pueden ser genéticas o ambientales. Se presenta un paciente de 17 años y 7 meses de edad. En su análisis clínico y radiográfico se diagnosticó como: Clase I esquelética, hiperdivergente, clase II molar y canina bilateral, mordida cruzada posterior bilateral, apiñamiento severo superior e inferior, órgano dental 22 cruzado. El tratamiento consistió de la fase de expansión maxilar y alineación, apertura de espacio para el 22, nivelación, detallado y retención. La aparatología utilizada brackets prescripción Roth ,022 x ,028, expansor maxilar tipo Hyrax, bandas en los molares 6's superiores, tubos bondeables en 6's y 7`s superiores e inferiores, open coil de Niti. La retención a cargo de circunferencial superior e inferior y fijo de 13-23 y 33-43, tiempo de tratamiento activo 1 año y 11 meses.
Causes of transverse discrepancies of the maxilla can be genetic or environmental. We present a patient of 17 years 7 months of age. In his clinical and radiographic analysis he was diagnosed as: Skeletal Class I, hyperdivergent, malocclusion class II bilateral molar and canine, bilateral posterior cross bite, severe upper and lower crowding, crossed dental organ. The treatment consisted of maxillary expansion and alignment, opening of space for 22, leveling, detailing and retention. The appliances used were brackets prescription Roth .022 x .028, maxillary expander type Hyrax, molar bands in the upper molars 6s, tubes in 6's and 7's upper and lower, open coil of Niti. The retention in charge of upper and lower circumferential retainer and a bonded retainer from 13- 23 and 33-43, time of active treatment 1 year 11 months.
