Temporal relationship between sleep-time masseter muscle activity and apnea-hypopnea events: A pilot study

pubmed

J Oral Rehabil. 2022 Jan;49(1):47-53. doi: 10.1111/joor.13271. Epub 2021 Nov 15. ABSTRACT BACKGROUND: Obstructive sleep apnea (OSA) is the most common sleep disorder due mainly to peripheral causes, characterized by repeated episodes of obstruction of the upper airways, associated with arousals and snoring. Sleep bruxism (SB) is a masticatory muscle activity during sleep that is…

pubmed

Int Orthod. 2021 Dec;19(4):697-706. doi: 10.1016/j.ortho.2021.09.008. Epub 2021 Oct 22. ABSTRACT Two case reports are presented showing how the strategic use of skeletal anchorage via orthodontic miniscrews manages to solve the complex problems of orthodontic disimpaction of second mandibular molars with excellent anchorage control and reduction of the adverse effects common to the use of…

Severe transverse discrepancy in adult Class III patient: Parallel rapid palatal expansion with a bone-borne tandem expansion screws (TSE) followed by lingual fixed appliance for a non-surgical treatment: A case report

pubmed

Int Orthod. 2021 Dec 3:S1761-7227(21)00144-3. doi: 10.1016/j.ortho.2021.11.001. Online ahead of print. ABSTRACT INTRODUCTION: Midpalatal suture opening in young adults is often difficult to achieve, depending on the suture maturation stage. It has been suggested that it is possible to avoid surgery and still achieve a successful pure skeletal expansion if a bone-borne Miniscrew-Assisted Rapid Palatal…

ABSTRACT INTRODUCTION: The objective was to describe the dental and skeletal changes obtained using the Carriere Motion Appliance (CMA), lateral cephalogram, and the corresponding cephalometric tracings. METHODS: A sample of 29 patients with Class II malocclusion (mean age, 12.6 ± 1.7…

Space closure by miniscrew-assisted mesialization of an upper third molar and partial vestibular fixed appliance: A case report

pubmed

Int Orthod. 2022 Jan 7:100602. doi: 10.1016/j.ortho.2021.100602. Online ahead of print. ABSTRACT This case report demonstrates how the use of skeletal anchorage and appropriate orthodontic biomechanics can be used to resolve even complex cases, reducing unwanted dental movements and allowing the use of a partial vestibular appliance. It describes the complete mesialization of the left…
