Dental Press J Orthod. 2024 Dec 16;29(6):e2423251. doi: 10.1590/2177-6709.29.6.e2423251.oar. eCollection 2024.

Abstract

Objective: The aim of this study was to evaluate the orthodontic retention protocols used by Brazilian orthodontists.

Methods: This cross-sectional study included 693 orthodontists who answered a web-based questionnaire with 22 questions regarding the participants' characteristics, their retainers' prescriptions, follow-up duration, and appliance fabrication.

Results: A 20.84% response rate was recorded. Most orthodontists reported working in private dental offices (94.7%), and female practitioners comprised 59.9% of the respondents. The mean age of the orthodontists was 41.05 years, and the mean time practicing as an orthodontist was 11.28 years. For the maxillary arch, most orthodontists (57.9%) declared to use the Hawley retainer, and for the mandibular arch, 49.1% use the bonded retainer. Regarding the retention phase duration, 85.6% recommend using a permanent retainer for the mandibular arch; and for the maxillary arch, 36.2% recommended using it for 1 to 2 years. The main reason that led orthodontists to choose a retention design was related to the initial malocclusion characteristics (72.9%), and the most mentioned explanation for choosing the retainer type and protocol was clinical experience (44.5%). Most orthodontists (85.3%) would like to have access to general guidelines/protocols for retention procedures after orthodontic treatment.

Conclusions: According to the answers, retention protocols varied among Brazilian orthodontists. Brazilian orthodontists preferred to use a Hawley retainer in the maxillary arch and a fixed straight retention bonded from canine to canine (3x3) in the mandibular arch.

Objetivo:: O objetivo deste estudo foi avaliar os protocolos de contenção utilizados pelos ortodontistas brasileiros.

Métodos:: Esse estudo transversal foi composto por 693 ortodontistas que responderam a um questionário eletrônico com 22 perguntas sobre características dos respondentes, prescrição das contenções, acompanhamento das contenções e confecções dos aparelhos.

Resultados:: A taxa de resposta foi de 20,84%. A maioria dos ortodontistas relatou trabalhar em consultórios particulares (94,7%), e as mulheres constituíram 59,9% dos respondentes. A média de idade dos ortodontistas foi de 41,05 anos, e a média de prática como ortodontista foi de 11,28 anos. Para a arcada superior, a maioria dos ortodontistas (57,9%) relatou utilizar placa de Hawley e, para a arcada inferior, 49,1% responderam que utilizam contenção fixa. Considerando-se a duração, 85,6% recomendam o uso de contenção permanente para a arcada inferior. Para a arcada superior, 36,2% recomendam o uso por 1 a 2 anos. A principal razão para os ortodontistas definirem o tipo de contenção foi a característica inicial da má oclusão (72,9%), e a razão mais citada para o uso e protocolo de contenção foi a experiência clínica (44,5%). A maioria dos ortodontistas (85.3%) gostaria que fossem disponibilizadas diretrizes/protocolos gerais para procedimentos de contenção após o tratamento ortodôntico.

Conclusões:: De acordo com as respostas, o protocolo de contenção variou entre ortodontistas brasileiros, os quais relataram preferência pelo uso da placa de Hawley na arcada superior e da contenção reta fixa colada de canino a canino (3x3) na arcada inferior.
