“…It is suggested that root parallelism influences the stability after orthodontic closure of anterior diastema 4 , 15 . However, the present results did not confirm any influence of root tip on space relapse ( Table 2 ) and so did the findings presented in a previous study 14 . Additionally, it was found that the slight mesial crown tip of the maxillary incisors occurred during the space closure remained stable posttreatment 14 .…”

Anterior spaces may interfere with smile attractiveness and compromise dentofacial harmony. They are among the most frequent reasons why patients seek orthodontic treatment. However, midline diastema is commonly cited as a malocclusion with high relapse incidence by orthodontists.ObjectivesThis study aimed to evaluate the stability of maxillary interincisor diastemas closure and the association of their relapse and interincisor width, overjet, overbite and root parallelism.Material and MethodsSample comprised 30 patients with at least a pretreatment midline diastema of 0.5 mm or greater after eruption of the maxillary permanent canines. Dental casts and panoramic radiographs were taken at pretreatment, posttreatment and postretention.ResultsBefore treatment, midline diastema width was 1.52 mm (SD=0.88) and right and left lateral diastema widths were 0.55 mm (SD=0.56) and 0.57 mm (SD=0.53), respectively. According to repeated measures analysis of variance, only midline diastema demonstrated significant relapse. In the overall sample the average relapse of midline diastema was 0.49 mm (SD=0.66), whilst the unstable patients showed a mean space reopening of 0.78 mm (SD=0.66). Diastema closure in the area between central and lateral incisors showed great stability. Multivariate correlation tests showed that only initial diastema width (β=0.60) and relapse of overjet (β=0.39) presented association with relapse of midline diastema.ConclusionsMidline diastema relapse was statistically significant and occurred in 60% of the sample, while lateral diastemas closure remained stable after treatment. Only initial diastema width and overjet relapse showed association with relapse of midline diastema. There was no association between relapse of interincisor diastema and root parallelism.

“…Nesses casos o ortodontista fica limitado a melhorar a disposição desses espaços. Outro ocorrido frequente é que a movimentação dos incisivos centrais para a mesial pode criar um espaço na distal entre os incisivos central e lateral (MORAIS JF, et al, 2012). Neste quesito, Machado AW (2014) orienta que caso haja algum espaço remanescente, a face distal dos laterais deve ser a área de escolha, pois é a área menos perceptível pelos leigos.…”

Objetivo: Comparar as duas principais formas de tratamento de diastemas anteriores: ortodôntico e restaurador. Métodos: Trata-se de uma revisão integrativa da literatura fundamentada nas bases de dados do SciELO, PubMed e Lilacs, tendo como critérios de inclusão: os artigos publicados na íntegra nos idiomas português, inglês e espanhol entre os anos de 2010 e 2022. Resultados: Baseando-se nos artigos encontrados as formas de tratamento discorridas são efetivas, porém é necessário que se obtenha um correto diagnóstico para que seja instituída a melhor opção para cada paciente, visando sempre a funcionalidade adequada e estética agradável. Considerações finais: Os diastemas podem causar prejuízos estéticos ao paciente, dessa forma cabe ao cirurgião-dentista diagnosticar corretamente a etiologia e identificar a melhor conduta a ser seguida no caso clínico, levando em consideração as expectativas do paciente e a sua condição financeira. Em alguns casos, o tratamento pode ser multidisciplinar, associando a ortodontia e a dentística restauradora.

“… 14 Inadequate root parallelism at the end of treatment has been also cited as a reason for median diastema relapse. 4 15 However, some mesial inclination of central incisors is preferred. 14 One follow-up study reported relapse of median diastema in 49% patients and found wider initial width of diastema and fremitus of maxillary incisors strongly associated with space opening.…”

AimThe aim of this study is to present a case of large maxillary median diastema closed by bodily movement of central incisors using Bapat power arm (BPA).Materials and methodsAfter extraction of mesiodens, a power chain with a force of 120 gm was applied to BPA ligated to preadjusted edgewise brackets bonded to maxillary central incisors to move them over round steel wire for closure of resultant diastema. Bonded retainer was placed after the closure of median diastema.ResultsThe median diastema was completely closed in 5 months period with almost bodily movement of incisors, which was confirmed by periapical X-ray.ConclusionBapat power arm was efficient in closing diastema without any discomfort or injury and was well accepted by the patient.How to cite this articleBapat SM, Singh C, Bandejiya P.
