Influência do tamanho das bases ósseas apicais no apinhamento dentário / Relationship of apical base length and dental crowding

Murillo-Goizueta, Oscar Edwin Francisco 26 January 2009 (has links)
A influencia de diversos fatores, principalmente no apinhamento dentário antero-inferior, vem sendo estudada desde muito tempo atras. Entretanto, a influencia do comprimento das bases apicais sobre o apinhamento dentario ainda nao foi esclarecida. Como existem evidencias na literatura de que esse fator pode influenciar o apinhamento dentario, resolveu-se desenvolver este trabalho para investigar a relacao entre comprimentos de bases apicais e apinhamento dentário superior e inferior na ma oclusao de Classe II completa. Um total de 80 documentacoes de pacientes ortodonticos retrospectivos, 47 homens e 33 mulheres com ma oclusao de Classe II completa foram divididas em 2 grupos segundo a discrepancia do perimetro do arco ou apinhamento inferior. O grupo 1, constituído por 25 pacientes com apinhamento inferior 3mm e com uma idade media de 12,81 anos; e o grupo 2, formado por 55 pacientes com apinhamento inferior < 3mm e com uma idade media de 13,33 anos. Os comprimentos das bases apicais da maxila e da mandibula e as discrepancias do perimetro dos arcos foram medidos nos cefalogramas e nos modelos de estudo iniciais, respectivamente. Os comprimentos das bases apicais e o apinhamento dentario foram comparados entre os grupos pelo teste t e tambem foram realizadas correlacoes entre os comprimentos das bases e o apinhamento para cada arco dentario. Os resultados mostraram que o grupo com maior apinhamento dentario teve comprimentos de bases apicais significantemente menores. Tambem foi encontrada uma correlacao negativa significante entre o comprimento das bases osseas e o apinhamento dentario na ma oclusao de Classe II completa. / The influence of many factors on dental crowding has been studied since long time ago, mainly in its relationship with anterior lower crowding. But, the influence of the apical bases length on the dental crowding was still not clarified. As there are evidences in the literature, it was decided to carry out the present study to investigate the relationship between apical base lengths and maxillary and mandibular anterior dental crowding in Class II malocclusions. Eighty retrospective orthodontic patients, 47 males and 33 females with complete Class II malocclusions were divided into two groups according to mandibular tooth-arch size discrepancy. The maxillary and mandibular apical base lengths and tooth-arch size discrepancies were measured on the initial cephalograms and plaster casts, respectively. The intergroup apical base length and crowding were compared with t tests and correlation between base length and dental crowding was investigated for each dental arch. Results demonstrated that the group with greater crowding had significantly smaller apical base lengths. A negative correlation was also found between apical base length and dental crowding in complete Class II malocclusions.
