A re‐usable 3D‐printed training model for the endodontic management of dental trauma in immature teeth

International Endodontic Journal, Volume 59, Issue 6, Page 1188-1199, June 2026.
Abstract Aim To develop a 3D‐printed model enabling treatment simulation of trauma‐related endodontic and restorative procedures like revitalization or placement of an apical plug on teeth with incomplete root formation. Methodology To generate a realistic training model suitable for trauma‐related simulations, CT‐Data sets were segmented, combined ...

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

Journal of Anatomy, Volume 248, Issue 6, Page 890-901, June 2026.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

Kinematic precision of gear trains [PDF]

Kinematic precision is affected by errors which are the result of either intentional adjustments or accidental defects in manufacturing and assembly of gear trains. A method for the determination of kinematic precision of gear trains is described.

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

Developmental Dynamics, Volume 255, Issue 5, Page 503-521, May 2026.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, Volume 2026, Issue 5, May 2026.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks

The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...

Implant Placement and Immediate Provisionalization After Alveolar Ridge Reconstruction in the Aesthetic Zone Using a Digital Workflow: A 1‐Year Prospective Case Series Study

Clinical Oral Implants Research, Volume 37, Issue 5, Page 543-557, May 2026.
ABSTRACT Introduction In single‐tooth replacement in the aesthetic zone, extensive bone defects require alveolar ridge reconstruction. A digital workflow involving CBCT and intraoral optical scanning enables a three‐dimensional assessment, prosthetically driven implant positioning, computer‐assisted implant surgery, and prefabrication of a temporary ...

Nonequilibrium phase transition in surface growth

, 2003
Conserved growth models that exhibit a nonlinear instability in which the height (depth) of isolated pillars (grooves) grows in time are studied by numerical integration and stochastic simulation.
