Assessment of treatment for functional posterior cross-bites in patients at the deciduous dentition phase

Abstract

The aim of this study was to clinically assess the results of treatment for functional posterior cross-bites by means of selective grinding in individuals at the deciduous dentition phase over a period of 12 months. From a total of 1,011 children examined in the 2-to-6-year age bracket, 26 with functional posterior cross-bites were selected. The sample was divided into 2 groups of 13 children each, group 1 receiving the treatment proposed and group 2 serving as the control group. Treatment was followed up by exercises designed to alter the children's muscular memory. The results showed that correction of functional posterior cross-bite was achieved for all the children treated, the correction remaining stable 12 months later. No self-correction of malocclusion occurred among the control group.

Effects of Palatal Expansion with Torque Activation using a Transpalatal Arch: A Preliminary Single-Blind Randomized Clinical Trial

“…ere are differences in the treatment of unilateral functional and nonfunctional crossbites. For instance, functional posterior crossbites can be treated mainly by occlusion adjustments, while TPAs are needed for treatment of nonfunctional crossbites [9,10,23].…”

Efetividade do tratamento ortodôntico interceptativo com aparelho removível em crianças com mordida cruzada e mordida aberta na fase de dentadura mista

“…Para o tratamento das variadas maloclusões, que inclui mordida cruzada, diversos autores preconizam o diagnóstico e interceptação nas dentaduras decídua e mista (Barich, 1952;Castaner, 2006;Tashima, Verrastro, Ferreira, Wanderley & Guedes-Pinto, 2003), período equivalente com dos pacientes tratados nesta pesquisa (5-12 anos), em que as respostas fisiológicas são mais favoráveis diante da bioelasticidade óssea existente, o que colabora significativamente para o reequilíbrio do sistema estomatognático e minimiza a necessidade de tratamentos futuros de maior complexidade na dentadura permanente (Dutra et al, 2004).…”

Unconventional usage of the Invisalign Fist system in treating a complete crossbite due to a lateral functional mandibular shift - a case report

“…przedwczesna utrata zębów mlecznych, ektopowe wyrzynanie zębów stałych, nadmierne wychylenie zębów siecznych szczęki zwiększające ryzyko urazu, zgryzy otwarte związane z nawykiem ssania palca, a także zgryzy krzyżowe przednie oraz boczne (3,4,9,10,12,13). Zgryz krzyżowy całkowity jest wadą zgryzu często występującą u młodych pacjentów, która powstaje na tle zwężenia szczęki lub występujących u pacjenta parafunkcji w postaci ssania palca i dysfunkcji oddychania (1,(13)(14)(15)(16). Dysproporcja szerokości górnego i dolnego łuku zębowego może prowadzić do powstania bocznego czynnościowego przemieszczenia żuchwy.…”

“…Dysproporcja szerokości górnego i dolnego łuku zębowego może prowadzić do powstania bocznego czynnościowego przemieszczenia żuchwy. Poślizg od pierwszego kontaktu zwarciowego Complete crossbite is a malocclusion often occurring in young patients, and it develops when there is maxillary narrowing or parafunctions such as finger sucking and breathing dysfunctions (1,(13)(14)(15)(16). The disproportion of the upper and lower dental arches' width can lead to lateral functional mandibular shift.…”
