Report of preparatory investigations about the usefulness of 'glass ceramics' in keratoplasty in a modification of Strampelli's method: Under the available implantation materials, glass ceramics seem to be the best as they join strongly to the bone and to interstitial tissues. As glass ceramics are suitable to keratoplasty, the necessity of loosing a tooth in osteo-odonto-keratoprosthesis after Strampelli can be avoided. Other advantages are standardization of the whole procedure, shortening of operation time and extension of indications for the operation. Based on our results, further investigations with longer implantation times, especially in eyes, are being performed at another place.

Sinter-crystallization is a specific method of producing glass-ceramics that allows the manufacture of complexly shaped products, composites and solder. However, it usually is limited when the glass powders used are characterized by a high crystallization trend. This study proposes a new opportunity to improve the sinter-crystallization and demonstrates the benefits of microwave processing using diopside (CaMg(SiO)) glass-ceramics with an enhanced crystallinity of ~70%.

To assess the biomechanical behaviors of endodontically treated molars (ETMs) restored with endocrowns composed of different materials, forty mandibular molars were assigned to five groups (n = 8 each). Untreated molars constituted the control group (group C); the rest of the teeth that underwent root canal therapy were restored with endocrowns composed of polycrystalline ceramics (ST zirconia, UPCERA) in group ZR, lithium disilicate glass ceramics (UP.CAD, UPCERA) in group LD, resin-based nanoceramics (Hyramic, UPCERA) in group NC, and feldspathic ceramics (CEREC Blocs, Sirona) in group FC.

Controllable Nano-Crystallization in Fluoroborosilicate Glass Ceramics for Broadband Visible Photoluminescence.

Nanomaterials (Basel)

January 2025

Sino-French Hoffmann Institute, School of Basic Medical Science, Guangzhou Medical University, Guangzhou 511436, China.

A transparent fluoroborosilicate glass ceramic was designed for the controllable precipitation of fluoride nanocrystals and to greatly enhance the photoluminescence of active ions. Through the introduction of BO into fluorosilicate glass, the melting temperature was decreased from 1400 to 1050 °C, and the abnormal crystallization in the fabrication process of fluorosilicate glass was avoided. More importantly, the controlled crystallizations of KZnF and KYbF in fluoroborosilicate glass ceramics enhanced the emission of Mn and Mn-Yb dimers by 6.

January 2025

Division of Prosthodontics, Department of Restorative Sciences, University of Minnesota, Minneapolis, Minnesota, USA.

Purpose: This pilot study aimed to compare the flexural strength of Amber Mill CAD to IPS e.max CAD and to determine the impact of different crystallization protocols on the flexural strength of Amber Mill CAD ceramics.

Materials And Methods: Amber Mill CAD ceramic blocks of a known Vita Classic shade were selected for testing against control IPS e.
