pubmed

J World Fed Orthod. 2020 Mar;9(1):32-43. doi: 10.1016/j.ejwf.2020.01.001. Epub 2020 Feb 12. ABSTRACT INTRODUCTION: This case demonstrates that hybrid application of clear aligners can be a rational and efficient approach for treating malocclusions, as compared with a clear aligner therapy alone option in which the magnitude of some movements would require a higher number of…

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.…

Analysis of tooth anatomy in adults with ideal occlusion: A preliminary study

Am J Orthod Dentofacial Orthop. 2020 Feb;157(2):218-227. doi: 10.1016/j.ajodo.2019.03.024. ABSTRACT INTRODUCTION: The aim of this study was to investigate the vestibular anatomy of teeth in samples of adult Italian and Mozambican subjects in ideal occlusion and permanent dentition and identify any anatomic characteristics that may influence bonding in the straight-wire technique. METHODS: Linear measurements and…

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…
