Implant therapy in older patients: Prosthetic considerations and biomechanical implications for frailty/aging

Periodontology 2000, EarlyView.
Abstract Background Population aging is reshaping prosthodontic care for both partially and completely edentulous individuals. In older adults, conditions such as frailty, comorbidities, polypharmacy, and cognitive decline can have a direct impact on the biological and biomechanical demands of implant therapy, thereby influencing the success of implant

Crystal Nucleation of Palladium-Doped Lithium Disilicate Glass [PDF]

, 2015
The effect of concentration of palladium particles on crystal nucleation was investigated for lithium disilicate glass. The heterogeneous nucleation rate for 470°C and 480°C were calculated for a concentration of 0.001% palladium by weight.

The Effects of Chlorhexidine, Essential Oil‐Based, and Stannous Fluoride Mouthrinses on the Color Stability and Surface Roughness of CAD/CAM Ceramics

Clinical and Experimental Dental Research, Volume 12, Issue 5, October 2026.
ABSTRACT Objectives The long‐term esthetic performance of CAD/CAM ceramic restorations may be influenced by repeated exposure to therapeutic mouthrinses. This study evaluated the effects of chlorhexidine, essential oil‐based, and stannous fluoride mouthrinses on the color stability (ΔE) and surface roughness (Ra) of glazed and polished CAD/CAM ceramics.

The Influence of Preparation Design in Biologically Oriented Preparation and Horizontal Preparation on Tooth Structure Removal: An In Vitro Study

Clinical and Experimental Dental Research, Volume 12, Issue 5, October 2026.
ABSTRACT Objectives Several clinical scenarios indicate the need for full‐coverage crowns. However, these restorations require substantial tooth reduction, which may compromise pulpal vitality and biological principles. This study aimed to evaluate the effect of the biologically oriented preparation technique on the volume and weight of tooth structure

Microstructural Factors Governing Fracture Toughness in Lithium Silicate Dental Glass‐Ceramics Using Machine Learning

Journal of the American Ceramic Society, Volume 109, Issue 10, October 2026.
ABSTRACT The microstructure of lithium silicate‐based dental glass‐ceramics (LS‐DGCs) is highly complex, consisting of multiple crystalline phases with diverse morphologies embedded within a residual glass matrix. This microstructure, which evolves through compositional changes and thermal treatment, strongly influences fracture resistance. Due to this
