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.…

pubmed

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…

Dual-section versus conventional archwire for en-masse retraction of anterior teeth with direct skeletal anchorage: a finite element analysis

pubmed

BMC Oral Health. 2021 Feb 25;21(1):87. doi: 10.1186/s12903-021-01443-0. ABSTRACT BACKGROUND: The aim of this study is to compare the biomechanical effects of the conventional 0.019 × 0.025-in stainless steel archwire with the dual-section archwire when en-masse retraction is performed with sliding mechanics and skeletal anchorage. METHODS: Models of maxillary dentition equipped with the 0.019 ×…
