A new method for improved standardisation in three-dimensional computed tomography cephalometry [PDF]

open access: yes, 2010
Interest for three-dimensional computed tomography cephalometry has risen over the last two decades. Current methods commonly rely on the examiner to manually point-pick the landmarks and/or orientate the skull. In this study, a new approach is presented,

Third Palatal Rugae as Stable Landmarks for Intraoral Models' Superimposition in Extraction Cases: A Retrospective Cohort Study

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives To validate the third palatal rugae as stable reference landmarks for the superimposition of maxillary digital models in premolar extraction cases. Materials and Methods Maxillary intraoral scanning digital models of 22 extraction patients, obtained before (T0) and after approximately 4 months of incisor retraction (T1), were ...

A New Method of Predicting Final Mandibular Length Based on the Morphology of Cervical Vertebrae

open access: yesDiagnostics
Background/Objectives: Methods for predicting final mandibular length have been studied for many years. We aimed to estimate the final mandibular length at the end of the growth period by analyzing changes in cervical vertebral morphology using ...

Intronic Single Nucleotide Polymorphisms in FGFR2 Gene Association With Non‐Syndromic Mandibular Retrognathism

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Mandibular retrognathism (MR) is a skeletal malocclusion in which patients have a deficient mandibular length, resulting in a more posterior position of the mandible. We aimed to investigate the association between Single nucleotide polymorphisms (SNPs) in Fibroblast Growth Factor Receptor 2 (FGFR2) gene and MR in germans.

3D Analysis of Mandibular and Glenoid Fossa Responses to Bone‐Anchored Maxillary Protraction in Patients With UCLP

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Introduction Bone‐anchored maxillary protraction (BAMP) has been increasingly used to correct midface deficiency and Class III malocclusion in patients with unilateral cleft lip and palate (UCLP). However, its three‐dimensional (3D) effects on the mandible remain insufficiently explored.
