Avaliação subjetiva da aceitabilidade das imagens de tomografia computadorizada de feixe cônico para o planejamento de implantes osteointegrados

open access: yesRevista de Odontologia da UNESP
Introdução: Para realização de mensurações precisas para implantes osteointegrados, é necessário que as imagens tomográficas apresentem uma qualidade mínima, que permita a visualização clara das estruturas anatômicas. Objetivo: Diante disso, avaliou-

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Prevalence of Different Types of the Bifid Mandibular Canal and its Relationship with the Position and Width of the Main Canal in the Panoramic Radiographs

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2020
Background and Objectives: The presence of bifid mandibular canals are among the anatomical variations in the inferior mandibular canals. Lack of attention to these canals can lead to complications, such as anesthesia and bleeding during dental ...

Traumatic Neuroma Following Sagittal Split Osteotomy of the Mandible [PDF]

open access: yes, 2007
A 16-year-old male underwent bilateral sagittal split osteotomy of the mandible to correct a mandibular deficiency. Twenty-one years later, a routine panoramic radiograph revealed a radiolucent lesion on the left side of the mandible.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

A Case Report of Sporadic Burkitt\'s Lymphoma of Mandible with Involvement of Breast and Multiple Pelvic and Abdominal Organs

open access: yesJournal of Mazandaran University of Medical Sciences, 2017
Burkitt’s lymphoma (BL) is a poorly differentiated B-cell lymphoma. It is rare and in Africa as well as occurs most often in children and young adults. In general, BL includes about 1-2 % of all lymphomas in adults, especially those under 35 years of age,
