The aim of the study was to develop the most optimal variant for placing the reinforcing element of a fiberglass splint with the mobility of the anterior teeth on the basis of a parallelometric study of the diagnostic models of the jaws depending on the type of occlusion and the degree of bone resorption. For the most optimal variant of the placement of the reinforcing element of the adhesive splint with orthognathic bite and deep incisal overlap, the front slope of the model was selected with the transfer of the reinforcing element of the adhesive splint onto the lingual surface. With direct, prognathic and progenic bite and bone resorption up to ¼ height (according to retrography data), the back slope of the model was selected with the placement of the reinforcing element of the adhesive splint on the vestibular surface of the lower jaw. The disadvantage of locating the reinforcing element on the lingual surface when the incisors were crowded was that after the application of the splint and inter-proximal adaptation, the change in the position of the teeth was not corrected. On the contrary, when applying an adhesive splint on the vestibular surface with the help of restoration, it was possible to completely restore the original position of the teeth and fix it for a long time.

Obstacles and drivers in the adoption of Standardized Structured Reporting (SSR): insights from pathologists.

The adoption of Standardized Structured Reporting (SSR) in pathology offers significant potential to improve data consistency, completeness, and interoperability. This study combines quantitative data from an online survey of Belgian pathologists with qualitative insights from focus group interviews to identify key factors influencing SSR implementation. Survey results demonstrate strong support for SSR, particularly in enhancing report uniformity, completeness, and efficiency, especially in multidisciplinary teams and for secondary data use.

Bone defect repair remains a great challenge in the field of orthopedics. Human body essential trace element such as copper is essential for bone regeneration, but how to use it in bone defects and the underlying its mechanisms of promoting bone formation need to be further explored. In this study, by doping copper into mesoporous bioactive glass nanoparticles (Cu-MBGNs), we unveil a previously unidentified role of copper in facilitating osteoblast mitophagy and mitochondrial dynamics, which enhance amorphous calcium phosphate (ACP) release and subsequent biomineralization, ultimately accelerating the process of bone regeneration.

Lattice structures are an innovative solution to increase the strength-to-weight ratio of a structure. In this study, two polymeric hybrid lattice structures-"FRB" (a heterogenous structure which is indeed a BCC structure reinforced by FCC unit cells dispersed in a way to form a chessboard pattern in each layer) and the "Multifunctional" (a homogenous structure whose unit cells are a combination of FCC and BCC unit cells where their central nodes are connected)-are proposed, fabricated via liquid crystal display 3D printing technique, and their mechanical characteristics are evaluated under quasi-static loading, experimentally and numerically. The results indicate a 15.

Background: Conservative dentistry introduced modern restoration designs, contributing to the greater use of partial-coverage ceramic restorations. New strong bondable ceramic materials made fabricating partial coverage ceramic restorations easier to restore the badly destructed teeth.
Aim Of The Study: This study investigated the impact of three distinct overlay preparation designs on the marginal fit (both before and after thermal aging) and the fracture resistance of overlay restorations fabricated using advanced zirconia-reinforced lithium disilicate (ALD) CAD/CAM glass-ceramic blocks.
Autumn and winter air phytofiltration - Are plants able to biofilter air during peak pollutant emissions?

Electronic address:
Air pollution is highest in winter. The high concentration of particulate matter (PM) and trace elements (TE) after the growing season is influenced by increased pollutant emissions, unfavorable meteorological conditions, and the low efficiency of air phytofiltration. Plants that can remove pollutants from the air during the growing season are leafless in autumn/winter, and therefore unable to capture PM/TE effectively.
