“…Um eine Aussage über signifikante Unterschiede bei der Nettowirkung der verschiedenen Therapieformen treffen zu können, mussten etwaige, bereits zum Behandlungsbeginn bestehende signifikante Unterschiede berück-sichtigt werden. Um eine Alpha-Fehler-Kumulierung zu vermeiden, wurde das Signifikanzniveau nach Bonferroni [23] adjustiert. Wegen der großen Variabilität der Behandlungsdauer zwischen den einzelnen Therapiegruppen wurde eine Korrelationsanalyse durchgeführt.…”

“…Wegen der großen Variabilität der Behandlungsdauer zwischen den einzelnen Therapiegruppen wurde eine Korrelationsanalyse durchgeführt. Zur Überprüfung eines etwaigen Zusammenhangs zwischen der Behandlungsdauer (Zeitraum zwischen T1 und T2) und der therapeutisch induzierten Nettowirkung wurde der Korrelationskoeffizient nach Pearson [23] bestimmt.…”

“…To make reliable statements on significant differences among the net outcomes of various treatment approaches, significant differences at baseline must be taken into account. To avoid alpha-level capitalization, the level of significance was adjusted according to the Bonferroni method [23]. Since treatment duration varied greatly among the various treatments, we carried out an inter-group assessment for correlations.…”

“…Since treatment duration varied greatly among the various treatments, we carried out an inter-group assessment for correlations. To detect any relationships between treatment duration (between T1 and T2) and net outcome/treatment-induced effect, we determined Pearson's correlation coefficient [23].…”

In young adults fixed functional appliances are a treatment alternative to extraction therapy but to a lesser extent to orthognathic surgery. Because of their limited skeletal effects and minor changes in the profile they are indicated only in patients with a moderately severe Class II malocclusion. Pre-treatment proclined mandibular incisors limit the scope of indications for fixed functional appliances, as they can cause an increase in lower incisor proclination. Significant reductions in profile convexity are achievable only by combined orthodontic and surgical treatment of the malocclusion. When performing camouflage orthodontics in conjunction with maxillary premolar extractions in adults, an increase in the nasolabial angle, which is often esthetically undesirable, has to be discussed as a potential side effect and has to be taken into account when considering the different therapeutic approaches.

Effects of fixed appliances in correcting Angle Class II on the depth of the posterior airway space

et al. 2011

View full text Add to dashboard Cite

Analyses of lateral cephalograms indicate that Angle Class II treatment with fixed appliances does not prevent sleep apnea in patients at risk. Nevertheless, this study does not permit absolutely reliable conclusions about the dimensions of the pharyngeal airway space. As the lateral cephalogram provides good images of structures in the midsagittal plane but is incapable of imaging the transverse dimension, there is an automatic lack of information concerning the precise width and volume of the extrathoracic airway space.
