Effects of bone- and air-tissue inhomogeneities on the dose distributions of the Leksell Gamma Knife$^{\circledR}$ calculated with PENELOPE [PDF]

open access: yes, 2005
Monte Carlo simulation with PENELOPE (v.~2003) is applied to calculate Leksell Gamma Knife$^{\circledR}$ dose distributions for heterogeneous phantoms. The usual spherical water phantom is modified with a spherical bone shell simulating the skull and an air-filled cube simulating the frontal or maxillary sinuses. Different simulations of the 201 source

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Retrospective analysis of the correlation between the facial biotype and the inclination of the upper canine cusp axis to the occlusal plane [PDF]

open access: yes, 2016
Permanent maxillary canines are the second most frequently impacted teeth and the prevalence of this clinical condition is estimated to be 1-2% in the general population.

Incisor cross‐sectional area at the cementoenamel junction correlates with an increased reliance on frugivory in anthropoid primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains

Maxillary anterior cortical bone thickness: An imperative parameter for implant solidity - 3-dimensional cone beam CT study

open access: yesJournal of Indian Academy of Oral Medicine and Radiology, 2020
Background: This study aims to evaluate alveolar height, buccal, and palatal cortical bone thickness using cone beam computed tomography (CBCT) useful for radiological pre-assessment for various surgical procedures of maxillary anterior region. Materials

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

A 3D FEM Comparison of Labial and Lingual Orthodontics for Maxillary Midline Diastema Closure [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Introduction: Lingual orthodontics is gaining popularity day by day. However very few information is present in literature regarding physiologic reaction that occurs after force application, efficacy and rate of tooth movement in lingual orthodontics ...

AI-enabled Automatic Multimodal Fusion of Cone-Beam CT and Intraoral Scans for Intelligent 3D Tooth-Bone Reconstruction and Clinical Applications [PDF]

open access: yesarXiv, 2022
A critical step in virtual dental treatment planning is to accurately delineate all tooth-bone structures from CBCT with high fidelity and accurate anatomical information. Previous studies have established several methods for CBCT segmentation using deep learning.

Is cranial anatomy indicative of fossoriality? A case study of the mammaliaform Hadrocodium wui

open access: yesThe Anatomical Record, EarlyView.
Abstract Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle.
