“…[2][3][4] However, many practitioners apply brackets indiscriminately, making the finishing stage of comprehensive orthodontic treatment more difficult and time-consuming. [4][5][6] Carlson and Johnson 7 have enumerated 4 elements that demand attention when initially positioning brackets: (1) bracket base adaptation to the contour of the tooth surface, (2) evaluation of the rotational position of each bracket from the occlusal direction, (3) determination of the vertical position of each bracket, and (4) determination of the desired slot angulations of each bracket by evaluating the position of the roots. All of these elements are necessary for ideal bracket placement and can be adequately visualized when completing an indirect bonding setup.…”

“…This inaccuracy results in a lack of root parallelism, of mutually protected guidances and also in inadequate intercuspation [3,5]. Therefore, when brackets are not properly positioned, arises the need to place compensatory bends on the archwires [6] or rebond brackets, which results in increased treatment time [7,8].…”

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.Key words: Dental bonding; Orthodontic appliances; Orthodontic brackets Os padrões de posicionamento posterior de bráquetes são confiáveis?ResuMO Objetivo: Verificar a precisão no nivelamento de cristas marginais dos padrões de posicionamento de bráquetes de Alexander e Viazis em dentes posteriores. Métodos: Foram selecionados 80 pares de modelos de gesso com dentição permanente completa e sem desgastes ou restaurações oclusais. 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.

“…1 Many techniques have been described to improve bracket positioning ,2 involving several different instruments .3-5 Although the Boone and Dougherty gauges have been widely used, 2,3,6,7 McLaughlin and Bennett have designed gauges to measure bracket heights according to their bracket placement chart. 8 Metallic or wooden jigs are available for bracket heights ranging from 2mm to 5.5mm from the incisal or occlusal edges, with each jig having a bracket placement gauge on each end.…”
