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…

Association of the mid-palatal suture morphology to the age and to its density: A CBCT retrospective comparative observational study

pubmed

Int Orthod. 2021 Jun;19(2):235-242. doi: 10.1016/j.ortho.2021.03.002. Epub 2021 Mar 27. ABSTRACT OBJECTIVE: The twofold aim of the present investigation was to: 1. evaluate the degree of mid-palatal suture (MPS) maturation via CBCT in relation to patient age, and 2. to determine whether there was a correlation between quantitative (i.e., suture density) and qualitative (i.e., suture…

Micro-computed tomography evaluation of general trends in aligner thickness and gap width after thermoforming procedures involving six commercial clear aligners: An in vitro study

pubmed

Korean J Orthod. 2021 Mar 25;51(2):135-141. doi: 10.4041/kjod.2021.51.2.135. ABSTRACT OBJECTIVE: To assess the effects of thermoforming on aligner thickness and gap width in six aligner systems with the same nominal thickness. METHODS: Six passive upper aligners of different brands were adapted to a single printed cast. Each sample was evaluated with high-resolution micro-computed tomography. To…
