Résumé
ABSTRACT Objective: To emphasize the importance of diagnosis and discuss the therapeutic approaches that can be used in the orthodontic treatment of Class I malocclusion associated with two impacted maxillary canines. The opening of spaces for traction of these teeth by means of rapid maxillary expansion or extraction of maxillary premolars was contraindicated in the case reported. Therefore, it was decided to open spaces with projection of incisors. Results: The obtained results were satisfactory, as a good occlusion was obtained, with adequate functional guides, as well as an improvement in the facial appearance. Conclusion: The projection of the incisors prior to traction of the impacted maxillary canines proved to be a valid option in the case described. Ten years after completion of treatment, the case is stable, maintaining periodontal health.
RESUMO Objetivo: Destacar a importância do diagnóstico e discutir as abordagens terapêuticas que podem ser utilizadas no tratamento ortodôntico da má oclusão de Classe I associada a dois caninos superiores impactados. Relato de caso: A abertura de espaço para tracionar esses dentes por meio de expansão rápida da maxila ou exodontia de pré-molares superiores era contraindicada no caso relatado. Portanto, decidiu-se abrir espaço por meio da projeção dos incisivos. Resultados: Os resultados obtidos foram satisfatórios, pois obteve-se uma boa oclusão, com guias funcionais adequadas, além da melhoria no aspecto facial. Conclusão: A projeção dos incisivos prévia ao tracionamento dos caninos superiores impactados mostrou-se uma opção válida no caso descrito. Dez anos após a finalização do tratamento, o caso apresenta-se estável, mantendo a saúde periodontal.
Résumé
Maxillary canine has a significant importance in functional and esthetic aspect of the occlusion. Clinicians must have a sound knowledge regarding the management of impacted maxillary canines as is second most common teeth prone for impaction after third molars. With early detection and timely interception and well planned orthodontic treatment the impacted canines can be successfully bought to the occlusion. This article gives an overview of etiology, diagnosis and prognosis of impacted canine
Résumé
Los dientes impactados presentan muchos problemas. Pueden comprometer la movilidad dentaria, la estética, y los resultados funcionales. Después del tercer molar superior, los caninos superiores presentan la impactación más común, los cuales pueden impactar en posición vestibular o palatina, y son más comunes en mujeres que en varones. Con un manejo terapéutico quirúrgico y ortodoncico adecuado, los caninos superiores impactados pueden erupcionar y ser guíados a una posición adecuada en el arco dental. En este artículo se presenta un caso quirúrgico-ortodóncico de un canino superior impactado vestibular en una mujer adulta, tratada mediante la técnica cerrada con preservación de las papilas.
Impacted teeth present many problems. They can compromise tooth movement, esthetics, and functional outcomes. After the maxillary third molar, the maxillary canines are the most commonly encountered impaction, which can be impacted buccally or palatally, and are more common in female patients than in male patients. With a well-managed surgical and orthodontic treatment, impacted maxillary canines can be erupted and guided to an appropriate location in the dental arch. This article presents a surgical-orthodontic case of maxillary canine impacted buccally in an adult woman, treated with the closed technique for preservation of papillae.

Objective To explore induced eruption techniques of the impacted maxillary canine with labial medial inclination. Methods A total of 38 cases with upper impacted canines with labial medial inclination were selected. The impacted canine was connected to the buccal hook of the upper first molar band, moved distantly and uprightly and then drawn to the dental arch after the pressure to the adjacent teeth was removed. Results After average 18 months treatment, 38 patients had good functions. The deeper impacted canines in 5 patients were extracted, and then the dental arch spaces closed. The lateral incisors of root resorption in 4 patients were extracted. The premolars in 19 patients were removed, and 10 patients without extractions. Then the impacted canines were moved into dental arch. There was no aggravated root resorption during the treatment process. Conclusion When the maxillary canine with labial medial inclination is impacted, it is moved distantly and uprightly by elastic line connected to the buccal hook of the maxillary first molar band, and then drawn to the dental arch. The process is smoothly and the neighbor teeth are protected.
