Superhydrophilic multifunctional nanotextured titanium dental implants: short and long-term response in a porcine model. | LitMetric

AI Article Synopsis

Article Abstract

Current clinical demand in dental implantology is for a multifunctional device with optimum mechanical properties, improved biocompatibility and bioactivity, and having differential interactions with cells and pathogenic agents. This would minimise bacterial infection, biofilm formation and modulate inflammation, leading to a fast and durable osseointegration. The present study intends to establish the multifunctional behaviour of surface modified titanium dental implants that are superhydrophilic, with unique micro-nano or nanoscale topographies, developed by a facile hydrothermal technique. Here, the short and long-term performances of these textured implants are tested in a split mouth design using a porcine model, in pre- and post-loaded states. Quantitative and qualitative analyses of the bone implant interphase are performed through μ-CT and histology. Parameters that evaluate bone mineral density, bone contact volume and bone implant contact reveal enhanced bone apposition with better long-term response for the nano and micro-nano textured surfaces, compared to the commercial microtextured implant. Concurrently, the nanoscale surface features on implants reduced bacterial attachment by nearly 90% , outperforming the commercial variant. This preclinical evaluation data thus reveal the superiority of nano/micro-nano textured designs for clinical application and substantiate their improved osseointegration and reduced bacterial adhesion, thus proposing a novel dental implant with multifunctional characteristics.

The fungus Candida albicans is a prominent cariogenic fungal agent that works in association with Streptococcus mutans to accelerate the formation of oral cancer and tooth decay. This study evaluates caffeine-encapsulated titanium oxide nanoparticles (CF-TiO2 NPs) for their potential to prevent biofilm formation on teeth and enhance oral anticancer treatment by influencing apoptotic gene regulation. The synthesized CF-TiO2 NPs were characterized using UV, SEM, EDAX, and FTIR analyses, and their antioxidant activity was confirmed through free radical quenching studies.

Purpose: This study assesses the impact of Cold Atmospheric Pressure Plasma (CAP) pretreatment on the bond strength of two-piece hybrid ceramic abutment crowns in implant dentistry. The objective is to ascertain whether CAP can be employed as an alternative or complementary technique to conventional methods.

Methods: 80 titanium bases and 80 VITA ENAMIC polymer-infiltrated ceramic network (PICN) crowns were divided into 8 groups (n = 10) based on different surface pretreatments of the crowns before cementation: no treatment (A), hydrofluoric acid (HF) (B), HF and silane (C), silane (D), CAP (AP), HF and CAP (BP), HF, CAP, and silane (CP), and CAP and silane (DP).

Guided Bone Regeneration in the Posterior Mandible Using a Resorbable Metal Magnesium Membrane and Fixation Screws: A Case Report.

Case Rep Dent

December 2024

Department of Prosthodontics, Geriatric Dentistry and Craniomandibular Disorder, Charité-Universitätsmedizin Berlin, Aßmannshauser Straße 4-6 14197, Berlin, Germany.

Due to bone loss, implant placement in the posterior mandible is often impossible without prior augentative procedures. The reconstruction of bone defects with horizontal and vertical components using particulated bone grafts requires the placement of a mechanically stable structure for stabilization of the grafting material. Although titanium-reinforced membranes and titanium meshes have been shown to be effective in this indication, the necessity of their removal, often in a separate surgical procedure, is seen as a disadvantage.
