Orthodontics is temporomandibular disorder-neutral

Angle Orthod. 2016 Jul;86(4):649-54. doi: 10.2319/051015-318.1. Epub 2015 Oct 29. ABSTRACT OBJECTIVES: To assess if subjects with a clinical diagnosis of temporomandibular disorders (TMDs) have a similar prevalence of orthodontic history as a population of TMD-free individuals and to assess if those subjects who have a history of ideal orthodontics have fewer symptoms than those…

Optical properties of orthodontic aligners–spectrophotometry analysis of three types before and after aging

Prog Orthod. 2015;16:41. doi: 10.1186/s40510-015-0111-z. Epub 2015 Nov 18. ABSTRACT BACKGROUND: The aim was to assess and compare absorbance and transmittance values of three types of clear orthodontic aligners before and after two cycles of in vitro aging. METHODS: Nine samples of orthodontic aligners from three different manufacturers (Invisalign, Align Technology, Santa Clara, CA, USA;…

Load deflection characteristics of square and rectangular archwires

Int Orthod. 2016 Mar;14(1):1-14. doi: 10.1016/j.ortho.2015.12.011. Epub 2016 Jan 27. ABSTRACT AIMS: To determine and compare the relative stiffness of a large selection of commonly-used square and rectangular steel, super-tempered steel, NiTi, and TMA orthodontic archwires of various cross-sections, in order to provide the clinician with a useful, easy-to-consult guide to archwire sequence selection. MATERIALS…

Caries prevention during orthodontic treatment: In-vivo assessment of high-fluoride varnish to prevent white spot lesions

Am J Orthod Dentofacial Orthop. 2016 Feb;149(2):238-43. doi: 10.1016/j.ajodo.2015.07.039. ABSTRACT INTRODUCTION: Our objective was to evaluate the efficacy of a fluoridated varnish in preventing white spot lesions in patients with fixed appliances. A laser-induced fluorescence device was used to determine any correlations between the degree of demineralization and the length of the observation period, the…

Quantitative cone-beam computed tomography evaluation of premaxilla and symphysis in Class I and Class III malocclusions

Int Orthod. 2016 Jun;14(2):143-60. doi: 10.1016/j.ortho.2016.03.014. Epub 2016 Apr 16. ABSTRACT AIMS: In order to compare the premaxilla and symphysis in Class I and Class III individuals, we measured the following parameters on CBCT scans: incisor inclination, symphyseal morphology, upper alveolar process morphology, symphyseal and maxillary leeway space, as well as anterior and posterior maxillary…

Stress relaxation properties of four orthodontic aligner materials: A 24-hour in vitro study

Angle Orthod. 2017 Jan;87(1):11-18. doi: 10.2319/113015-813.1. Epub 2016 Jun 17. ABSTRACT OBJECTIVE: To investigate the stress release properties of four thermoplastic materials used to make orthodontic aligners when subjected to 24 consecutive hours of deflection. MATERIALS AND METHODS: Four types of aligner materials (two single and two double layered) were selected. After initial yield strength…

Preliminary biometric analysis of mesiodistal tooth dimensions in subjects with normal occlusion

Am J Orthod Dentofacial Orthop. 2016 Jul;150(1):105-15. doi: 10.1016/j.ajodo.2015.12.021. ABSTRACT INTRODUCTION: The aims of this study were to confirm the efficacy of the Bolton index in a group of natural Class I white Italian patients with complete dentition, minimal crowding, and no previous orthodontic treatment, and to evaluate the mesiodistal tooth dimensions with multivariate cluster…
