Short-term variation in the subgingival microbiota in two groups of patients treated with clear aligners and vestibular fixed appliances: A longitudinal study

pubmed

Orthod Craniofac Res. 2021 May;24(2):251-260. doi: 10.1111/ocr.12427. Epub 2020 Oct 15. ABSTRACT OBJECTIVE: To evaluate the subgingival microbiological changes during the first six months of therapy with clear aligners (CAs) and fixed appliances (FAs). The null hypothesis was that there would be no microbiological differences between the two. SETTING/SAMPLE: Two groups of patients to be…

MicroCT X-ray comparison of aligner gap and thickness of six brands of aligners: an in-vitro study

pubmed

Prog Orthod. 2020 May 11;21(1):12. doi: 10.1186/s40510-020-00312-w. ABSTRACT BACKGROUND: To investigate and compare the gap (i.e. fit) and thickness of six aligner systems (Airnivol, ALL IN, Arc Angel, F22, Invisalign and Nuvola) using industrial computed tomography (CT). The null hypothesis was that there would be no detectable differences in either measurement between the aligners investigated.…
