Resumo: Objective: Investigate the marginal ridges leveling accuracy of Alexander and Viazis bracket placement methods.Methods: Eighty pairs of dental casts were selected, with complete permanent dentition, without occlusal wear or restorations. A linking line between mesial and distal ridges of posterior teeth was done to measure the occlusal thirds with digital caliper. The means, obtained from 3 different examiners, were compared with the values of Alexander and Viazis’ equations through One-way ANOVA with α=0.05.Results: The second premolar placement value (x) suggested by the authors showed no difference in comparison to the occlusal third size of the sample teeth (p>0.05), however for the first premolars, a significant difference was found (p<0.001). The value adopted for positioning on the first permanent molars (x-0.5mm) is consistent with the size of the occlusal third of these teeth (p=0.0531). A significant difference was also found for the second permanent molars bracket positioning between the predefined value (x-1mm) and the sample (p<0.001).Conclusions: The vertical positioning values proposed by Alexander and Viazis for placement of second premolars and first permanent molars do contribute to the leveling of marginal ridges, which cannot be applied for the values recommended for the first premolars and second permanent molars.

Uma linha ligando as cristas marginais mesial e distal dos dentes foi demarcada, visando a medição do terço oclusal com um paquímetro digital milimetrado. As médias obtidas de 3 examinadores foram comparadas com os valores propostos por Alexander e Viazis através do teste de One-Way ANOVA com α=0,05.Resultados: O valor (x) proposto para o posicionamento nos segundos pré-molares não apresentou diferença com a dimensão do terço oclusal da amostra (p>0,05); entretanto para os primeiros pré-molares houve diferença significativa (p<0,001). O valor de posicionamento adotado para os primeiros molares permanentes (x-0,5mm) foi condizente com a dimensão do terço oclusal destes dentes (p=0,0531). Houve diferença significativa entre o valor (x-1mm) predifinido para os segundos molares permanentes e a amostra (p<0,001).Conclusões: Os valores de posicionamento de acessórios propostos por Alexander e Viazis para os segundos pré-molares e para os primeiros molares permanentes promovem o nivelamento das cristas marginais, entretanto o mesmo não ocorre para os primeiros pré-molares e segundos molares permanentes.EDIPUCRS - Editora Universitária da PUCRS2016-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/1753910.15448/1980-6523.2016.1.17539Revista Odonto Ciência; Vol. 31 No. 1 (2016); 16-20Revista Odonto Ciência; v. 31 n. 1 (2016); 16-201980-65230102-946010.15448/1980-6523.2016.1reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/17539/14980Copyright (c) 2016 Revista Odonto Ciênciainfo:eu-repo/semantics/openAccessMattielo, Fabiano Dalla Lanade Arruda, Marcelo Bichat PintoXavier, Natália LimaBortoly, Thaís Gelatti2016-11-17T19:21:22Zoai:ojs.revistaseletronicas.pucrs.br:article/17539Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2016-11-17T19:21:22Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
