Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.

Relationship between bruxism and different types of mechanical complications in implant‐supported prosthesis: A systematic review with meta‐analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose This review aimed to assess the prevalence and association between bruxism and different types of mechanical complications in implant‐supported prosthesis, which is missing in the literature. Methods A systematic review with meta‐analysis was carried out in PubMed/Medline, Web of Science, Embase, Cochrane Library, LILACS, and Scopus ...

Linoleic acid addition prevents Staphylococcus aureus biofilm formation on PMMA bone cement

Biofilm
Acrylic bone cement is widely used in vertebroplasty to treat osteoporosis-induced vertebral compression fractures. However, infection after vertebroplasty is problematic and previous work has suggested loading the bone cement with an antibiotic for ...

Peri‐Implant Soft‐Tissue Phenotype Modification for Refractory Peri‐Implant Mucositis: A 12‐Month Prospective Clinical Study With Ultrasonographic Analysis

Journal of Periodontal Research, EarlyView.
Surgical treatment of refractory peri‐implant mucositis with a free gingival graft (FGG) was effective in disease resolution, achieving reductions in probing pocket depth (PPD) and inflammation. Significant gains in mucosal thickness (MT) and keratinized mucosa width (KMW), as well as partial recession coverage and re‐establishment of attached mucosa ...

Fracture properties of an acrylic bone cement.

Acta of bioengineering and biomechanics, 2008
This study investigated experimentally the fracture properties, i.e., the fatigue strength, the resistance to crack propagation and the fracture toughness, of an acrylic bone cement (Cemex RX). The mean endurance limit was determined following the staircase method. The endurance limit was estimated at 9.2 MPa.

Ageing‐related modification of sleep and breathing in orexin‐knockout narcoleptic mice

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Narcolepsy type‐1 (NT1) is a lifelong sleep disease, characterised by impairment of the orexinergic system, with a typical onset during adolescence and young adulthood. Since the wake–sleep cycle physiologically changes with ageing, this study aims to compare sleep patterns between orexin‐knockout (KO) and wild type (WT) control mice at ...

Critical evaluation of pulse-echo ultrasonic test method for the determination of setting and mechanical properties of acrylic bone cement: influence of mixing technique.

Ultrasonics, 2015
Currently there is no reliable objective method to quantify the setting properties of acrylic bone cements within an operating theatre environment. Ultrasonic technology can be used to determine the acoustic properties of the polymerising bone cement ...

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5‐knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central ...

Curing characteristics of acrylic bone cement

Journal of Materials Science: Materials in Medicine, 2002
Commercial acrylic bone cements are supplied as two components, a polymer powder and a liquid monomer. Mixing of the two components is followed by a progressive polymerization of the liquid monomer to yield a solid mass, a high level of heat being generated during this exothermic reaction. The exposure of bone to high temperatures has led to incidences
