Fracture load comparison of a new Fiber-Reinforced Composite and Zirconia in All-on-Four Prosthesis: An In Vitro Study.

Purpose: To compare the fracture load of two framework materials, zirconia and a new fiber-reinforced composite (FRC), for full-arch implant-supported rehabilitations using various cross- sections.

Material And Methods: A cobalt-chromium metal model simulating the all-on-four concept and including 2 anterior straight and 2 posterior 45- degree angled multi-unit digital implant analogs was manufactured. 4 straight multi-unit abutments were screwed onto the implant analogs.

"Sticky Bone" Preparation Device: A Pilot Study on the Release of Cytokines and Growth Factors.

Sticky bone, a growth factor-enriched bone graft matrix, is a promising autologous material for bone tissue regeneration. However, its production is strongly dependent on manual handling steps. In this sense, a new device was developed to simplify the confection of the sticky bone, named Sticky Bone Preparation Device (SBPD).

In vivo evaluation of the biocompatibility and biodegradation of a new denatured plasma membrane combined with liquid PRF (Alb-PRF).

Guided bone regeneration (GBR) is a process that involves the regeneration of bone defects through the application of occlusive membranes that mechanically exclude the population of non-osteogenic cells from the surrounding soft tissue. Interestingly, platelet-rich fibrin (PRF) has previously been proposed as an autologous GBR membrane despite its short-term resorption period of 2-3 weeks. Recent clinical observations have demonstrated that, by heating a liquid platelet-poor plasma (PPP) layer and mixing the cell-rich buffy coat zone, the resorption properties of heated albumin gel with liquid-PRF (Alb-PRF) can be significantly improved.

Newly formulated 5% 5-aminolevulinic acid photodynamic therapy on Candida albicans.

Background: A large number of systemic diseases can be linked to oral candida pathogenicity. The global trend of invasive candidiasis has increased progressively and is often accentuated by increasing Candida albicans resistance to the most common antifungal medications. Photodynamic therapy (PDT) is a promising therapeutic approach for oral microbial infections.

Growth Factors Release From Concentrated Growth Factors: Effect of β-Tricalcium Phosphate Addition.

Background: Platelet concentrates represent a new approach to improve tissue regeneration and can be used alone or together with autogenous bone, recombinant human growth factors, and/or other biomaterials, to enhance tissue regeneration. Among platelet concentrates, concentrated growth factors (CGFs) exhibit an interesting clinical and biotechnological application potential.

Objective: The aim of this study was to evaluate the in vitro release of 4 growth factors (bone morphogenetic proteins [BMP] -2, BMP-7, transforming growth factor [TGF] -β1, and insulin-like growth factor [IGF] -1) by the enzyme-linked immunosorbent assay (ELISA) technique, in CGFs mixed or not with β-tricalcium phosphate (β-TCP), using or not the Round-up device, at different times.
