Dens Invaginatus as a Biomechanical Risk Modifier in Dental Trauma: Finite Element Analysis

Dental Traumatology, EarlyView.
ABSTRACT Introduction/Aims Traumatic dental injuries are common in childhood and may adversely affect functional and psychosocial well‐being. Dens invaginatus, a developmental anomaly caused by the infolding of the enamel organ during odontogenesis, alters tooth morphology and may influence biomechanical behavior under traumatic loading.

Finite Element Analysis of Dentoalveolar Stress in Combat Sports Using Hybrid and Conventional Mouthguards

Dental Traumatology, EarlyView.
ABSTRACT Aim This study aimed to contribute to the development of modern mouthguards by evaluating the stresses generated by hook and uppercut punches applied during combat sports on dentoalveolar structures and mouthguards, the protective effectiveness of different mouthguard designs, and the resulting deformations using three‐dimensional finite ...

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

How do forelimb long bones adapt in rhinoceroses? An in‐depth examination of their microanatomy

Journal of Anatomy, EarlyView.
Here, we study the bone structure in the forelimb long bones of the five extant species of rhinoceroses. By combining traditional description of virtual sections made on the bones (A) with in‐depth cartographies of the variation of bone compactness and anisotropy (B), we show how bone tissue can adapt to extreme forces and constraints in the second ...

Growing together: Developmental integration and modularity in the human talus–calcaneus complex

Journal of Anatomy, EarlyView.
This study investigates morphological integration and trabecular bone development in the human talus–calcaneus complex during postnatal ontogeny. The two bones exhibit strong integration throughout development, with differing bone volume fraction trajectories presumably reflecting their distinct functional roles during bipedal gait acquisition ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

Journal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Cumulative effects of lifelong systemic excess growth hormone on postcranial skeletal morphology in adult mice

Journal of Anatomy, EarlyView.
Our μCT‐based pilot study reveals size and shape disparity in the adult postcranial skeleton of growth‐hormone model (bGH) mice relative to wild‐type mice. bGH mice have larger and more sexually dimorphic bones, with a systemic radiodensity increase in bony sesamoids and associated, but typically uncalcified, soft tissues.

Modelling compressive loading in large‐bodied mammals reveals distinct biomechanical strategies in proboscidean humeri

Journal of Anatomy, EarlyView.
Graviportal proboscideans differ in limb morphology, adopting slender or more robust long bone morphotypes. Finite element analyses (FEA) on extant and extinct taxa reveal functional differences between morphotypes, with robust humeri exhibiting lower peak stress under neutral and off‐axis loading.
