Osteohistology of the unusually fast‐growing theropod dinosaur Ceratosaurus

Journal of Anatomy, EarlyView.
We report the histology of multiple elements attributed to four individuals of Ceratosaurus. We find that the histology and growth models corroborate previous reports of rapid tissue growth in the genus. Abstract Ceratosaurus is a large‐bodied non‐avian theropod dinosaur known from the Upper Jurassic Morrison Formation of North America and is ...

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

Journal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs

Journal of Anatomy, EarlyView.
A combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.

The 3D‐printed shell complete denture technique: Simplifying prosthodontic diagnosis prior to implant planning

Journal of Prosthodontics, EarlyView.
Abstract Traditionally, artificial teeth arrangements or the definitive complete dentures are used to establish important prosthodontic parameters such as the occlusal plane orientation, vertical dimension, and the incisal edge position. The relationship of these elements with the underlying bony structures is commonly evaluated using advanced planning

Digital denture with mucostatic base and functional borders: A cast‐free digital technique

Journal of Prosthodontics, EarlyView.
Abstract Digital complete dentures fabricated using a mucostatic impression, like intraoral scans, are desirable for their beneficial effect on long‐term residual ridge stability but may have less retention than those fabricated with a mucocompressive impression.
