Mandibular dental arch short and long-term spontaneous dentoalveolar changes after slow or rapid maxillary expansion: a systematic review

ABSTRACT Objective: The aim of this systematic review was to analyze the short and long-term spontaneous dentoalveolar changes of the mandibular dental arch after slow (SME) or rapid (RME) maxillary expansion in the mixed and early permanent dentitions. Methods: An electronic search was performed in t...

Impact of rapid maxillary expansion on nasomaxillary complex volume in mouth-breathers

ABSTRACT Objective: To assess the volumetric changes that occur in the nasomaxillary complex of mouth-breathing patients with transverse maxillary deficiency subjected to rapid maxillary expansion (RME). Methods: This was a controlled, prospective intervention study involving 38 mouth-breathing patie...

Miniscrew-assisted rapid palatal expansion for managing arch perimeter in an adult patient

ABSTRACT Introduction: Etiology of dental crowding may be related to arch constriction in diverse dimensions, and an appropriate manipulation of arch perimeter by intervening in basal bone discrepancies cases, may be a key for crowding relief, especially when incisors movement is limited due to underly...

Retention period after treatment of posterior crossbite with maxillary expansion: a systematic review

ABSTRACT OBJECTIVE: The aim of this systematic review was to evaluate the duration of the retention period in growing patients undergoing maxillary expansion and its relation with posterior crossbite stability. METHODS: Search strategies were executed for electronic databases Cochrane Library, Web of ...

Evaluation of the rapid and slow maxillary expansion using cone-beam computed tomography: a randomized clinical trial

ABSTRACT OBJECTIVE: The aim of this randomized clinical trial was to evaluate the dental, dentoalveolar, and skeletal changes occurring right after the rapid maxillary expansion (RME) and slow maxillary expansion (SME) treatment using Haas-type expander. METHODS: All subjects performed cone-beam compu...

Three dimensional evaluation of alveolar bone changes in response to different rapid palatal expansion activation rates

ABSTRACT Introduction: The aim of this multi-center retrospective study was to quantify the changes in alveolar bone height and thickness after using two different rapid palatal expansion (RPE) activation protocols, and to determine whether a more rapid rate of expansion is likely to cause more adverse...

Non-surgical treatment of transverse deficiency in adults using Microimplant-assisted Rapid Palatal Expansion (MARPE)

ABSTRACT Introduction: Maxillary transverse deficiency is a highly prevalent malocclusion present in all age groups, from primary to permanent dentition. If not treated on time, it can aggravate and evolve to a more complex malocclusion, hindering facial growth and development. Aside from the occlusal c...

Análise da distribuição das tensões em maxila submetida à expansão cirurgicamente assistida com aparelho ósseo-suportado

A expansão de maxila cirurgicamente assistida (EMCA) é a modalidade de tratamento que tem como objetivo romper as regiões de reforço maxilar permitindo seu movimento expansivo gradativamente. Tal movimento pode ser realizado às custas de aparelhos dento-suportado, dento-muco-suportado, implanto-supo...

Expansão rápida da maxila osseossuportada: um relato de caso e passo a passo laboratorial

A expansão rápida da maxila osseossuportada tem sido amplamente utilizada na clínica ortodôntica, entretanto ainda existem dúvidas em relação ao planejamento e efeitos do tratamento. É objetivo do presente artigo relatar um caso clínico descrevendo passo a passo as etapas de planejamento, confec...

Opções de tratamento para a discrepância transversal da maxila no adulto

Na Ortodontia atual tem-se criado diferentes opções de tratamento devido à rápida evolução de tecnologia e ferramentas de diagnóstico. Esse fato tem aumentado a abrangência de pacientes beneficiados. O tratamento ortodôntico em adultos deve ser implementado com a preocupação de oferecer maior ...
