Fusion of the 2nd maxillary molar with the impacted 3rd molar
Subject matter: The dentist has to deal with complicated cases of fused molars, which are rather rare and morphologically very varied. A wrong or incomplete diagnosis can considerably complicate a planned therapy.The authors describe a case of apical periodontal complication of fused teeth that had to be removed surgically.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Supernumerary Teeth Adjacent to Fully Erupted Third Molars in all four Quadrants: A Case Report [PDF]
Supernumerary teeth are formed due to disturbances during the developmental stages of a tooth. The prevalence of supernumerary teeth is higher in the maxilla than the mandible and shows a predilection for the male gender.

Multimodal Data‐Driven Microstructure Characterization
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

The Loss of First Permanent Molar in Young Patients
Introduction: The loss of first permanent molar significantly reduces the biological quality of the dentition. In addition to prosthetic rehabilitation in indicated cases, we can also take advantage of orthodontic space closure with mesial shift of the ...

Accidental Swallowing of a Molar Band [PDF]
Accidental ingestion or aspiration of foreign bodies is considered as a medical emergency in dentistry. Despite their rare occurrence, accidental ingestions are associated with various complications and morbidity, thereby necessitating prevention of ...
