Association between dental restorations and artefacts on head magnetic resonance images in paediatric patients

open access: yesInternational Journal of Paediatric Dentistry, Volume 34, Issue 5, Page 546-553, September 2024.
Abstract Background Magnetic resonance imaging (MRI) has become an important diagnostic tool for paediatric patients. The association between dental restorations and MRI artefacts/distortions, however, is unclear. Aim To investigate the association between dental restorations and artefacts in head MRI in children.

Comparison of linear measurement accuracy on cone-beam computed tomography images and digital lateral cephalometric radiographs

open access: yesمجله دانشکده دندانپزشکی اصفهان, 2013
Introduction: Two-dimensional (2D) imaging has limitations in the evaluation of three-dimensional (3D) structures. In recent years, it has become possible to acquire 3D data of patients.

A simulator for maxillo-facial surgery integrating cephalometry and orthodontia [PDF]

open access: yesComputer Aided Surgery 5(3) (2000) 156-165, 2006
Objectives : This paper presents a new simulator for maxillo-facial surgery, that gathers the dental and the maxillo-facial analyses together into a single computer-assisted procedure. The idea is first to propose a repositioning of the maxilla, via the introduction of a 3D cephalometry, applied to a 3D virtual model of the patient's skull.

Orthognathic surgery improves compromised natural head position and pharyngeal airway in patients with Skeletal Class II or III malocclusion

open access: yesJournal of Oral Rehabilitation, Volume 51, Issue 9, Page 1778-1784, September 2024.
Abstract Background Natural head position (NHP), pharyngeal airway and maxillofacial growth pattern are correlated. The author's previous studies proved that following surgical correction of Skeletal Class II malocclusion, the over‐extended NHP returned upright, and the pharyngeal airway space (PAS) dimension expanded.

Antiseizure medication use during pregnancy and neonatal growth outcomes: A systematic review and meta‐analysis

open access: yesBritish Journal of Clinical Pharmacology, Volume 90, Issue 8, Page 1827-1837, August 2024.
Aims We aimed to systematically synthesize the current published literature on neonatal growth outcomes associated with antiseizure medication (ASM) use during pregnancy. Methods We searched seven databases, from inception to 23 March 2022. We investigated small for gestational age (SGA) and low birth weight (LBW) as primary outcomes and birth weight ...

Computer aided planning for orthognatic surgery [PDF]

open access: yesProceedings of the 16th International Conference on Computer Assisted Radiology and Surgery, CARS 2002 Springer-Verlag (Ed.) (2002) 988-993, 2006
A computer aided maxillofacial sequence is presented, applied to orthognatic surgery. It consists of 5 main stages: data acquisition and integration, surgical planning, surgical simulation, and per operative assistance. The planning and simulation steps are then addressed in a way that is clinically relevant. First concepts toward a 3D cephalometry are

MI image registration using prior knowledge [PDF]

open access: yesarXiv, 2007
Subtraction of aligned images is a means to assess changes in a wide variety of clinical applications. In this paper we explore the information theoretical origin of Mutual Information (MI), which is based on Shannon's entropy.However, the interpretation of standard MI registration as a communication channel suggests that MI is too restrictive a ...
