Laminin functionalization of zirconia abutments modulates early oral biofilm formation in vitro

Romualdus Nugraha Catur Utomo, Alena L. Palkowitz, Philipp Schräder, Lin Gan et autres

Background: Surface properties of dental implant abutment materials critically influence supragingival biofilm formation by determining the outcome of the early 'race for the surface', in which gingival epithelial cells and fibroblasts compete with bacteria for initial adhesion. This study hypothesized that biofunctionalization …

How does cement choice affect screw stability in implant-supported restorations with different abutment angulations? An in vitro study

Shaza Bishti, Katarzyna Hubryj, Martin Homa, Stefan Wolfart et autres

OBJECTIVE: To investigate the influence of cement type on the abutment-screw stability of single implant-supported restorations with different abutment angulations. MATERIALS AND METHODS: Fifty CAD/CAM implant-supported monolithic zirconia crowns simulating an upper premolar were divided into four groups (n = 10) according …

Optimizing implant hygiene: the added value of interproximal cleaning devices around implant-supported restorations—a systematic review and meta-analysis

Shaza Bishti, Stefan Wolfart, Taşkın Tuna

STATEMENT OF PROBLEM: A well-defined protocol for self-performed interproximal oral hygiene around implant-supported restorations is currently lacking. PURPOSE: To assess the efficacy of home-care interproximal cleaning measures used adjunctively to mechanical toothbrushing in reducing signs of inflammation in patients with peri-implant mucositis. …

Parodontitis triggert die Progression der Steatohepatitis durch Induktion einer gestörten intestinalen Mikrobiota

Astrid DeVriese, Shahrzad Ghadirzad, Qusay Salih, Mohammed Alatter et autres

Parodontitis und metabolische Dysfunktion-assoziierte steatotische Lebererkrankung (MASLD) gehören zu den weltweit häufigsten Erkrankungen. Die Rolle der intestinalen Mikrobiota in der Entstehung und Progression der MASLD ist experimentell gut dokumentiert. Wirts- und Umweltfaktoren, die eine intestinale Dysbiose induzieren, sind allerdings noch unzureichend verstanden. …

Three-unit CAD/CAM-manufactured lithium disilicate FDPs after an average observation period of 120 months

Martin Homa, Oliver Schneider, Peter Neumann, Lutz Endres et autres

OBJECTIVE: In recent decades, CAD/CAM-fabricated lithium disilicate restorations have become popular and have been approved for fixed dental protheses (FDPs) up to the second premolar since 2013. This multicenter follow-up study collected long-term clinical data on three-unit anterior and premolar FDPs made …

Factors Influencing the Screw Stability of Implant-Supported Single Crowns: An In Vitro Study

Shaza Bishti, Mohamad Shams Eddin Alsagher, Martin Homa, Stefan Wolfart et autres

The aim is to investigate the impact of retention type, implant/abutment angulation, and the presence of sealant/antimicrobial agents on screw loosening of implant-supported restorations. Fifty dental implants along with their respective abutments and screws were allocated to five groups (n = 10). …

In vitro plaque formation model to unravel biofilm formation dynamics on implant abutment surfaces

Romualdus Nugraha Catur Utomo, Alena L. Palkowitz, Lin Gan, Anna Rudzinski et autres

Background Biofilm formation on implant-abutment surfaces can cause inflammatory reactions. Ethical concerns often limit intraoral testing, necessitating preliminary in vitro or animal studies. Here, we propose an in vitro model using human saliva and hypothesize that this model has the potential to …

Pull‐Off Forces on Implant‐Supported Single Restorations by Sticky Food: An In Vitro Study

Shaza Bishti, Martin Homa, Stefan Wolfart, Taşkın Tuna

OBJECTIVE: To investigate the pull-off forces on implant-supported restorations caused by sticky food, to understand how much retention force cemented restorations must have to withstand chewing forces without unintentional retention loss. The influence of food type, restoration design, and surface treatment were …
