In vitro evaluation of the impact of intraoral scanner, scanning aids, and the scanned arch on the scan accuracy of edentulous arches

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the accuracy of complete maxillary and mandibular edentulous arch scans obtained using two different intraoral scanners (IOSs), with and without scanning aids, and to compare these results to those obtained using conventional impression methods.

Optimal cement paste yield stress for the production of stable cement foams [PDF]

Cement and Concrete Research (2019) 120, pp 142-151, 2019
Production of morphology-controlled cement foams remains challenging, mainly due to bubble stability issues during cement setting. The use of cement paste with high yield stress is expected to promote stability by damping intrinsic bubble kinetics. Here we show however that for given W/C ratio, fresh foam stability can be achieved instead by decreasing

Cytocompatible, radiopaque, and antibacterial bismuth‐doped gel‐derived 58S bioactive glasses

Journal of the American Ceramic Society, Volume 108, Issue 7, July 2025.
Abstract Larry L. Hench's research group first introduced gel‐derived bioactive glasses (BGs) in 1991. These BGs offer a broader range of bioactivity than traditional melt‐derived BGs. Highly porous gel‐derived glasses are suitable for various applications, such as bone and soft tissue engineering.

Cement selection for fixing implant restorations [PDF]

Stomatološki glasnik Srbije, 2019
Introduction When intraocclusal space is long enough, and patient has high aesthetic demands, cementing implant restoration is the proper choice. The aim of this study was to assess retentive forces of different cements used for fixing restoration to ...

Developments In Orthodontıc Cements

Turkish Journal of Orthodontics, 1994
In this literature review dental cements which were used for banding orthodontic attachments to teeth were evaluated. The general properties of zincphosphate cement, polycarboxylate cement and recently developed glass ionomer cements were discussed.

Molecular dynamics modeling of the effects of cementation on the acoustical properties of granular sedimentary rocks [PDF]

arXiv, 2006
The incidence of cementation processes on the acoustical properties of sands is studied via molecular dynamics simulation techniques. In our simulations, we consider samples with different degrees of compaction and cementing materials with distinct elastic properties.

Systematic Reviews Comparing Direct and Indirect Restorations: An Umbrella Review That Examines Restoration Type and Confidence in Results

Clinical and Experimental Dental Research, Volume 11, Issue 3, June 2025.
ABSTRACT Objectives There are two technologies for restoring individual structurally defective teeth. A direct restoration is applied chairside in one appointment, while an indirect restoration needs to be lab‐produced before application. This umbrella review of previous English systematic reviews was conducted to determine if there was any difference ...

Minimally Invasive Intraoperative Laser Vibrometry (MIVIB)—A Peroperative Method to Measure Fixation of the Ossicular Chain

Laryngoscope Investigative Otolaryngology, Volume 10, Issue 3, June 2025.
An objective assessment of the ossicular chain with laser vibrometry would likely improve the result of ossiculoplasty. MIVIB provides an objective assessment of the ossicular chain to identify specific fixations and therefore assist the surgeon in improving surgical outcomes. ABSTRACT Background Conductive hearing loss requires the surgeon to evaluate

Development and properties of composite cement reinforced coconut fiber with the addition of fly ash [PDF]

Journal of Sustainable Cement-Based Materials, 1(4), 186-191 (2012), 2017
In this paper, the effectiveness utilization of agriculture wastes and industrial wastes in the composites cement has been studied in terms of physical and mechanical properties. Twenty weight percent of fly ash and eighty weight percent of sand were added to the composite cement. The different weight percent of coconut fiber (3 wt. %, 6 wt. %, 9 wt. %,
