The Effect of Premolar Extractions on Incisor Position and Soft Tissue Profile in Patients with Class II, Division 1 Malocclusion*

Abstract

We did not observe that the patients' profiles did become worse after extraction therapy.

Combined Use of Retraction and Torque Arch with Mini-Screws: A Cephalometric Study

“…Although the retraction of maxillary incisors and remodeling at Point A caused an increase in the nasolabial angle, this increase was not statistically significant in our study. This result is compatible with the results of Conleya et al (29) and Weyrich et al (30). In the present study, overbite did not change significantly.…”

Studies on the Craniofacial Morphology of Adult Cleft Patients Using Euclidean Distance Matrix Analysis (EDMA)

“…EDMA wurde bisher zum Beispiel für den Vergleich der Schädelmorphologie von Eltern von Spaltkindern [21] und der Analyse chirurgischer Veränderungen bei invertierter L-Osteotomie von Hay et al [12] erfolgreich angewendet. Measurements of point coordinates are generally more error-prone than angular measurements, where errors according to Dahlberg are reported to be 0.326 (Li-EL) to 1.161 (interincisal angle) on lateral cephalograms [35].…”

“…Die Messung der Punktkoordinaten ist generell sensitiver für Fehler als anguläre Messungen, bei denen im Fernröntgenseitbild Fehler nach Dahlberg von 0,326 (Li-EL) bis 1,161 (Interinzisalwinkel) [35] angegeben werden. might have been expected.…”

Estudo comparativo dos efeitos dentoesqueléticos do tratamento da má oclusão de Classe II com o distalizador Jones jig e com extrações dos primeiros pré-molares superiores

“…Entretanto, a colaboração do paciente ainda se faz necessária no uso do aparelho extrabucal após a distalização, para ancorar e verticalizar as raízes dos molares superiores (PATEL, 2006;PATEL, 2010 (KESSEL, 1963;GRABER, 1969;DEANGELIS, 1973;KLAPPER et al, 1992;LUECKE;, protrusão e/ou apinhamento dos incisivos superiores (KESSEL, 1963;DEANGELIS, 1973), variável quantidade de trespasse vertical (KESSEL, 1963) e na obtenção de um perfil facial harmônico (CASE, 1964;BAUMRIND et al, 1996). FILHO et al, 2000;PATEL, 2006;PATEL et al, 2009;PATEL, 2010) enquanto outros avaliaram esses efeitos promovidos pelas extrações de 2 pré-molares na Classe II (LUECKE; STAGGERS, 1994;BISHARA et al, 1995;ONG;WOODS, 2001;JANSON et al, 2003a;JANSON et al, 2004a;MERAL et al, 2004;DEMIR et al, 2005;JANSON et al, 2006a;TADIC;WOODS, 2007;WEYRICH;LISSON, 2009 (JANSON et al, 2006b;JANSON et al, 2009b).…”

“…Este resultado sugere que a diminuição do ângulo SNA pode estar relacionada com a retração dos dentes ântero-superiores (BRAVO, 1994;BISHARA et al, 1995;JANSON et al, 2007b;LI AN T et al, 2008;WEYRICH;LISSON, 2009;SHARMA, 2010 (BRAVO, 1994;BISHARA et al, 1995;JANSON et al, 2007b;LI AN T et al, 2008;WEYRICH;LISSON, 2009;SHARMA, 2010).…”
