Biology of biomechanics: Finite Element Analysis of a Statically Determinate System to Rotate the Occlusal Plane for Correction of Skeletal Class III Openbite Malocclusion [PDF]

, 2015
Introduction In the absence of adequate animal or in-vitro models, the biomechanics of human malocclusion must be studied indirectly. Finite element analysis (FEA) is emerging as a clinical technology to assist in diagnosis, treatment planning, and ...

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

Orthodontics &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 ...

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

Orthodontics &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.
