A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Evaluation of the buccolingual position of maxillary and mandibular anteriorteeth roots by cone-beam computed tomography(CBCT)

open access: yesCaspian journal of dental research, 2020
Introduction: Evaluation of the position of anterior teeth in the alveolar bone for planning implant treatments is so important. The aim of this study was to evaluate the thickness of buccolingual/palatal bone at anterior teeth roots and the angle ...

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

open access: yesThe Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

The effect of increasing the gaps between the front teeth on torque and intrusion control of the incisors for anterior retraction with clear aligners: a prospective study

open access: yesBMC Oral Health
Objective To investigate the effect of sequential distalization on increasing gaps in the maxillary anterior teeth, focusing on the control of torque and three-dimensional teeth movement during anterior retraction with clear aligners in extraction cases.

Prevalence and Severity of Circumferential Alveolar Bone Loss Using CBCT Images: A Retrospective Study of 20,620 Surfaces of 5155 Teeth

open access: yesDiagnostics
Periodontal disease is a site-specific disease affecting the supporting tissues of the teeth. It is useful for the clinician to have information about the prevalence and severity of alveolar bone loss (ABL) according to the site, location, and position ...
