Comparing Digital Reduction Guides and Free‐Hand Techniques for Predoctoral Crown Preparation Accuracy

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives Insufficient tooth reduction compromises crown longevity and aesthetics. This study aimed to determine whether digitally designed, 3D‐printed reduction guides improved crown preparation accuracy and efficiency for dental students compared to freehand preparation.

Are the detection and dimensions of peri‐implant buccal bone defects influenced by different implant materials and their location? An experimental cone‐beam computed tomography study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background The aim of this study is to evaluate the impact of different implant materials and arrangements within the field of view (FOV) and exomass on the diagnostic accuracy and image quality of cone‐beam computed tomography (CBCT) for the detection of peri‐implant buccal bone defects of various sizes. Methods A total of 120 CBCT scans with

Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

open access: yesJournal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Engineering Photonic Pigments From Titania–Block Copolymer Composites

open access: yesMacromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.
