Association of the mid-palatal suture morphology to the age and to its density: A CBCT retrospective comparative observational study

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…

Resolution of lower second molar impaction through miniscrew-supported biomechanics: A proposal for a simplified classification

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…

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

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…

METHODS: Passive play and…

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

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…
