pubmed

J Orofac Orthop. 2019 Mar;80(2):57-67. doi: 10.1007/s00056-018-00164-4. Epub 2019 Jan 4. ABSTRACT AIMS: Mechanical properties along the length of latest generation “multi-force” archwires were measured and compare with commercially available thermally activated and non-thermally activated nickel-titanium (NiTi) archwires. MATERIALS AND METHODS: A modified deflection test was used to produce load/deflection curves for different positions along…

Does low-frequency vibration have an effect on aligner treatment? A single-centre, randomized controlled trial

pubmed

Eur J Orthod. 2019 Aug 8;41(4):434-443. doi: 10.1093/ejo/cjy076. ABSTRACT BACKGROUND: Low-frequency vibrations have been proposed as a means of accelerating tooth movement and reducing orthodontic treatment times. OBJECTIVE: To determine any differences in the accuracy of dental movement in patients treated with a low-frequency vibration aligner protocol and/or by reducing the aligner replacement interval with…

Class II subdivision correction with clear aligners using intermaxilary elastics

pubmed

Prog Orthod. 2018 Sep 1;19(1):32. doi: 10.1186/s40510-018-0221-5. ABSTRACT BACKGROUND: To describe an esthetic orthodontic treatment using aligners in an adult patient with class II subdivision associated with crowding and dental crossbite. An 18-year-old hyperdivergent male patient with skeletal class II from mandibular retrusion presented for an orthodontic treatment. Occlusally, the patient presents class II subdivision,…

pubmed

Cranio. 2020 May;38(3):158-167. doi: 10.1080/08869634.2018.1507094. Epub 2018 Aug 14. ABSTRACT Objective: To investigate the association between volumetric measurements of craniofacial morphology and temporomandibular disorders (TMDs). Methods: Computerized tomography (CT) scans of 20 individuals aged 18 to 40 with (TMD group) or without TMJ pain (control group) were gathered based on a case-control design. Three-dimensional reconstructions…

Effects of invisible orthodontic retainers on masticatory muscles activity during sleep: a controlled trial

pubmed

Prog Orthod. 2018 Jul 23;19(1):24. doi: 10.1186/s40510-018-0228-y. ABSTRACT BACKGROUND: This study aims to evaluate if invisible orthodontic retainers can affect sleep-time masticatory muscle activity (sMMA) over a short-term period in healthy individuals. METHODS: Nineteen (N = 19) healthy subjects underwent an in-home evaluation with a portable device for electromyographic (EMG) assessment. The study protocol provided…

Class III malocclusion and bilateral cross-bite in an adult patient treated with miniscrew-assisted rapid palatal expander and aligners

pubmed

Angle Orthod. 2018 Sep;88(5):649-664. doi: 10.2319/111617-790.1. Epub 2018 May 1. ABSTRACT This case report describes the use of a miniscrew-assisted rapid palatal expander and aligners to correct bilateral cross-bite and crowding in an adult patient with a Class III skeletal pattern. A digitally designed surgical guide was three-dimensionally printed and used to accurately insert four…

Skeletal and dentoalveolar effects of hybrid rapid palatal expansion and facemask treatment in growing skeletal Class III patients

pubmed

Am J Orthod Dentofacial Orthop. 2018 Feb;153(2):262-268. doi: 10.1016/j.ajodo.2017.06.022. ABSTRACT INTRODUCTION: The purpose of this study was to describe the skeletal and dentoalveolar changes in a group of growing skeletal Class III patients treated with hybrid rapid palatal expansion and facemask. METHODS: Twenty-eight growing patients with skeletal Class III malocclusion were treated using a rapid…
