Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

open access: yesBoreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

open access: yesBoreas, EarlyView.
Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...

Rescue Therapy With Quad Zygoma After Failure of Full‐Arch Implant Rehabilitation: A Retrospective Study With a Mean Follow‐Up of 8 Years

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To evaluate the long‐term clinical outcomes of quad zygomatic implants (ZIs) as a rescue therapy for patients with failed full‐arch implant rehabilitation in the maxilla due to advanced peri‐implantitis. Material and Methods This was a retrospective cohort study of all patients treated with the Quad Zygoma Protocol. Primary outcomes

Biomechanical Analysis of 3D Printed and Thermoformed EVA Custom‐Made Mouthguard: Experimental and Finite Element Analyses

open access: yesDental Traumatology, EarlyView.
ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...

Comfort and Usability of Digital Versus Conventional Custom‐Fit Mouthguards: A Randomized Clinical Trial

open access: yesDental Traumatology, EarlyView.
ABSTRACT Background/Objectives The use of mouthguards protects teeth and the supporting tissues against impacts. Digital impressions and 3D‐printed models can reduce manufacturing steps and minimize discomfort. This study evaluated the fit, comfort, and usability of custom‐made mouthguards, obtained by conventional and digital workflow, in amateur ...
