Abstract
To determine if an association exists between appliance-induced labial movement of mandibular incisors and gingival recession. Electronic databases were searched for studies with the terms: 'incisor', 'incisor proclination', 'tooth movement', 'orthodontic tooth movement', 'gingival recession' and 'orthodontic appliance'. The original articles and abstracts that met the initial inclusion criteria were retrieved, and their references hand searched for possible articles missed by the database searches. Inclusion criteria included human studies that suggested a link between labial movement of lower incisors produced by orthodontic treatment and gingival recession. Exclusion criteria included significant intrusion or extrusion of the mandibular incisors, periodontal disease, subjects taking medication that affects gingival health and subjects with systematic diseases. Seven articles fulfilled the selection criteria. Gingival recession after labial movement of lower incisors was assessed on dental casts, intra-oral slides, lateral cephalograms and gingival examination. The articles were analysed to determine the impact of their treatment methodology on the outcomes. No association between appliance-induced labial movement of mandibular incisors and gingival recession was found. Factors that may lead to gingival recession after orthodontic tipping and/or translation movement were identified as a reduced thickness of the free gingival margin, a narrow mandibular symphysis, inadequate plaque control and aggressive tooth brushing.
    • "Da jedoch beide Gruppen (Ex und non-Ex) gleichermassen betroffen waren und beide gleich lange retiniert wurden, dürfte dieser Aspekt im Vergleich der Gruppen keinen wesentlichen Einfluss ausgeübt haben.Aziz & Flores Mir 2011). Dies entspricht den Resultaten bereits durchgeführter Studien und Literaturübersichten (Artun & Grobety 2001, Aziz & Flores-Mir 2011, Djeu, et al. 2002, Melsen & Allais 2005). Es muss jedoch ergänzt werden, dass in jüngerer Zeit von gewissen Forschungsgruppen die These postuliert wurde, dass allein die Tatsache kieferorthopädisch behandelt und retiniert worden zu sein, unabhängig vom Behandlungsumfang zu Rezessionen führen kann ().

  • [Show abstract] [Hide abstract] ABSTRACT: Dieser Artikel gibt einen Überblick über Klassifikation, Ätiologie und Risikofaktoren von gingivalen Rezessionen. Des Weiteren werden prä- und postoperatives Management der Patienten, Indikationsstellungen zur Rezessionsdeckung und Einflussfaktoren, die das Operationsergebnis beeinflussen, diskutiert. Der Schwerpunkt liegt auf der präoperativen Phase und dem Erkennen von Ursachen, die zur Ausbildung von gingivalen Rezessionen führen können.

  • [Show abstract] [Hide abstract] ABSTRACT: To predict lower incisor proclination from initial cephalometric values in Class II division 1 patients treated in phase I with the Xbow appliance. Two hundred forty-nine mild to moderate Class II division 1 patients treated with the Xbow appliance as a phase I treatment were considered. Patients were in late mixed dentition or early permanent dentition. Commonly used cephalometric variables at T1 (before treatment) were used to predict lower incisor proclination after Xbow treatment (T2). A principal component analysis (PCA) was performed. The four extracted PCA components were skeletal component, incisal distance, anterior facial projection, and maxillo-mandibular relation. Thereafter, a multiple linear regression analysis (MLRA) was performed using the four extracted PCA components at T1 as predictor variables, and lower incisor inclination relative to the mandibular plane (L1-MP) at T2 as the dependent variable. The mean L1-MP at T1 was 95.46 degrees and the mean L1-MP at T2 was 98.51 degrees, resulting in a mean difference of 3.04 degrees. Only incisal distance and maxillo-mandibular relation PCA components had significance (P < .05) according to the MLRA. The overall model gave an adjusted R2 value (coefficient of determination) of 0.091. The best prediction model could account for only 9% of the total variability. Using common cephalometric variables at T1, average lower incisor proclination from Xbow treatment cannot be predicted in a clinically meaningful way.
