Resumo: Introduction : Clear aligners have gained popularity as they represent an aesthetic and comfortable option for orthodontic treatment. Different studies consider that rotation constitutes a difficult movement to achieve with clear aligners. Objectives : To conduct a systematic review and do an observational study to assess the accuracy and predictability of Invisalign® aligners in achieving molar derotation. Materials and Methods : The search strategy was conducted in the PUBMED database using the search key: “(((Orthodontic) AND (Clear aligner therapy)) OR (Invisalign)) AND (Rotation)”. The sample for the investigation consisted of 53 patients treated with Invisalign® aligners. Planned tooth movements for each patient were analysed using IBM® SPSS® Statistics software. Results : 18 articles checking the eligibility criteria were selected for the systematic review. Mean difference between predicted and achieved rotation obtained in the observational study was 1,59° overall, 1.67ᵒ for upper molars, 1.72ᵒ for lower molars. Estimated mean predictability of rotation was 79,75% overall, 83,18% for upper molars, 69,40% for lower molars. Effective rotation occurred between refinements. The use of attachments improved clear aligner's effectiveness to accomplish molar rotation. No significant differences were found in achieved molar rotations between attachment types, nor regarding auxiliaries. Discussion : Molar derotation occurs in numerous orthodontic conditions. Studies have assessed and compared clear aligner’s effectiveness to achieve molar derotations which appears to be influenced by various parameters. Conclusion : Molar derotation with clear aligners was shown to be predictable. Our results compared favourably or similarly with the ones described in the available literature.

Diferentes estudos consideram que a rotação constitui um movimento difícil de alcançar com alinhadores. Objetivos : Realizar uma revisão sistemática e conduzir um estudo observacional para avaliar a eficiência e previsibilidade dos alinhadores Invisalign® relativamente à desrotação de molares. Materiais e Métodos : Foi conduzida uma pesquisa na PUBMED usando as palavras-chave : “(((Orthodontic) AND (Clear aligner therapy)) OR (Invisalign)) AND (Rotation)”. A amostra da investigação foi constituída por 53 pacientes tratados com alinhadores Invisalign®. Os movimentos planeados para cada paciente foram analisados usando IBM® SPSS® Statistics. Resultados : Na revisão sistemática, foram selecionados 18 artigos que verificam os critérios de elegibilidade. A diferença entre a rotação prevista e efetiva observada no estudo observacional foi 1,59° globalmente, 1,67ᵒ para molares superiores, 1,72ᵒ para molares inferiores. A previsibilidade média estimada de rotação foi 79,75% globalmente, 83,18% para molares superiores, 69,40% para molares inferiores. Rotação efetiva ocorre entre refinamentos. O uso de attachments melhora a eficácia desses alinhadores. Não foram encontradas diferenças significativas nas rotações molares alcançadas entre tipos de attachments, nem com ou sem auxiliares. Discussão : Rotações de molares ocorrem em numerosas condições ortodônticas. Vários estudos avaliaram e compararam a eficiência dos alinhadores em alcançar desrotações de molares, e esta pareceu ser influenciada por vários parâmetros. Conclusão : A desrotação de molares com alinhadores mostrou-se previsível. Os resultados deste estudo compararam favoravelmente ou de forma semelhante aos descritos na literatura investigada.2024-11-11T15:00:13Z2024-01-01T00:00:00Z2024info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/20.500.11816/4693TID:203703839engFerreira, Laurine Marie Ilda Ribeiroinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-11-14T07:58:37Zoai:repositorio.cespu.pt:20.500.11816/4693Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-11-14T07:58:37Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
