Asymmetric Expansion with a Modified Quad Helix for Treatment of Isolated Crossbite
نویسندگان
چکیده
Unilateral posterior crossbite often involves only one tooth, especially upper first molar; in these cases it is never easy to obtain an asymmetrical movement of a molar and a proper planning of the orthodontic device with its anchorage is necessary to avoid arch overexpansion. Thanks to its simplicity and efficacy, the modified Quad Helix here described represents a valid therapeutic tool in cases of isolated posterior crossbite.

A comparison of different treatment techniques for posterior crossbite in the mixed dentition.
In this retrospective investigation, the changes occurring during the treatment of patients with posterior crossbite in the mixed dentition with the use of expansion plate and quad-helix appliances were evaluated and compared with those resulting from growth and development occurring in a control group of patients of similar age and type of malocclusion. The expansion plate group consisted of 1...
متن کاملCorrection of Unilateral Posterior Crossbite with Functional Mandibular Shift: A Case Report
Unilateral Posterior Crossbite with functional shift of the mandible is a common condition. Early treatment of the condition may prevent adverse effects on temporomandibular joint and masticatory muscles. Many treatment options have been discussed in the literature so far. During the deciduous and early mixed dentition stages, smaller forces can be used to achieve sutural expansion. When expans...

BACKGROUND Our objectives are to analyse and to compare the stress distribution and displacement of the craniofacial structures, following the application of forces from quad-helix and Nickel Titanium Palatal Expander-2 (NPE2) using finite element analysis. METHODS Three-dimensional finite element models of young dried human skull, quad-helix appliance and NPE2 were constructed, and the initi...
متن کاملA systematic review concerning early orthodontic treatment of unilateral posterior crossbite.
The aim of this study was to assess the orthodontic treatment effects on unilateral posterior crossbite in the primary and early mixed dentition by systematically reviewing the literature. A literature search was performed by applying the Medline database (Entrez PubMed) and covering the period from January 1966 to October 2002. The inclusion criteria were primary and early mixed dentition with...
