Avaliação de fatores relacionados ao tratamento da classe II com aparelho de Herbst /

Ravelli, Taísa Boamorte. January 2017 (has links)
Orientador: Ary dos Santos Pinto / Resumo: O objetivo deste estudo é avaliar as alterações dento esqueléticas induzidas pelo uso do aparelho de Herbst em indivíduos com má oclusão classe II divisão 1ª de Angle levando em consideração fatores de relevância clínica sobre o uso deste aparelho. A amostra foi constituída de telerradiografias cefalométricas em norma de 45° de arquivo que foram divididos em de 4 grupos: o grupo 1 (tratado) constituído de 25 indivíduos (lados direito e esquerdo), com idade entre 8 e 10 anos, tratados com Herbst de ancoragem tipo bandado. O grupo 2 (tratado) constituído de 34 indivíduos, com idade entre 14 e 18 anos, tratados com Herbst de ancoragem tipo bandado. O grupo 3 (tratado) constituído de 12 indivíduos, com idade entre 14 e 18 anos, tratados com Herbst de ancoragem tipo splint metálico. O grupo 4 (controle), utilizado para comparação, constituído de 23 indivíduos de 14 a 18 anos, de ambos os gêneros, não tratados ortodonticamente, com características semelhantes ao grupo experimental 2 e 3, derivados do Burlington Growth Centre da Faculdade de Odontologia da Universidade de Toronto, Canadá. Foi observado efeito da fase de maturidade, efeito do tratamento com ancoragem splintado e efeito de diferentes sistemas de ancoragem. Houve diferenças dentárias e esqueléticas quando se tratando em diferentes fases de maturidade; houve também maior efeito dentário quando se comparando com grupo controle; e não houve grande significância no tratamento considerando as diferentes formas de ancoragem. / Abstract: The objective of this study is to evaluate dental skeletal changes induced by the use of Herbst appliance in Class II individuals taking into consideration relevant clinical factors concerning the use of this appliance. The sample was constituted of oblique radiographies taken from archives and were divided into 4 groups: group 1 (treated) with 25 individuals (right and left side), age between 8 to 10 years, treated with Herbst with banded anchorage. Group 2 (treated) with 34 individuals, age between 14 to 18 years, treated with Herbst with banded anchorage. Group 3 (treated) with 12 individuals, age between 14 to 18 years, treated with Herbst with splinted anchorage. Group 4 (control) used for comparison, with 23 individuals between 14 to 18 years, both genders, not treated orthodontically, with similar characteristics to experimental groups 2 and 3, taken from Burlington Growth Centre from Dentistry Faculty, University of Toronto, Canada. It was observed phase of maturity effect, splint metallic treatment effect and different anchorage system effect. There was dental and skeletal differences when treating in different maturity phase, there was also more dental effects to splint metallic treatment and there was no significant difference when treating with two anchorage types. / Doutor

Foram empregados 40 documentações de indivíduos, metade dos quais foram tratados ortodônticamente sem indicação de extração de pré-molares e o restante tratados com indicação de extração dos pré-molares. O diagrama individualizado, construído com medidas obtidas da cefalometria e do modelo da arcada dentária mandibular, foram sobrepostos aos modelos em gesso, cujos resultados mostraram ser o mesmo confiável na determinação ou não de expansão das arcadas dentárias (forma da arcada dentária mandibular), para indicação ou não de extração de pré-molares e na quantificação das retrações ou vestibularizações dos dentes anteriores e da distalização ou ' mesialização dos caninos e primeiros molares inferiores. Assim podemos após a análise estatística dos resultados, propor que nos casos em que a discrepância total, ou seja, a discrepância de modelo mais a discrepância cefalométrica for maior que 10mm, indicar extração de premolares / Abstract: This Research applied the Andrade diagram as an adjunct in Orthodontic diagnosis and treatment planning, in cases of Class II division of Angle malocclusion. Forty documentations of individuals were used, half of the which were treated orthodontically without indication of bicuspid extraction and the remaining 20 with indication of bicuspid extraction. The individualized diagram by cephalometric measurements and by lower arch cast measurements was superposed to the stone models. The results showed that the diagram use is relialy secure in determining the need or not of dental arches expansion (lower arch dental form). Also to indicate or not the bicuspid extractions, to quantify the anterior teeth tetraction or buccal movement and the mesial or distal movement of the canines and the first molars. In this manner, after the results of statistical analysis, it was proposed that in cases of total discrepancy, in other words, discrepancy plus cephalometric discrepancy larger them 10 mm, to indicate the bicuspid extractions / Doutorado / Ortodontia / Doutor em Odontologia

Crown size comparisons in patients with unilateral palatally displaced canines

Eliason, Joseph, Lindauer, Steven J 01 January 2015 (has links)
Abstract CROWN SIZE COMPARISONS IN PATIENTS WITH PALATALLY DISPLACED CANINES By Joseph L. Eliason, D.D.S. A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University. Virginia Commonwealth University, 2015 Thesis Director: Steven J. Lindauer, D.M.D., M.Dent.Sc. Professor and Chair, Department of Orthodontics There has been significant debate over the past decades regarding the etiology of palatally displaced canines. Theorized risk factors include agenesis or malformation of the lateral incisors, incisor retroclination, transverse deficiency, or genetic predisposition. The purpose of this study is to compare the linear and volumetric measurements of canines and lateral incisors to determine how tooth size relates to canine impaction. Cone-beam CT images for 40 patients with unilateral palatally displaced canines were utilized to measure the linear dimensions and total crown volume of canines and lateral incisors and to compare those teeth on the impaction side with their isomers on the non-impaction side. Results showed that unilateral palatally impacted maxillary canine crowns were slightly, but statistically significantly wider and larger in volume than their non-impacted isomers. Lateral incisor crowns adjacent to impacted canines were significantly shorter than those adjacent to non-impacted canines.
