BACKGROUND: Direct metal laser sintering (DMLS) is an additive manufacturing technique that allows the fabrication of dental implants layer by layer through the laser fusion of titanium microparticles. The surface of DMLS implants is characterized by a high open porosity with interconnected pores of different sizes; therefore, it has the potential to enhance and accelerate bone healing. To date, however, there are no histologic/histomorphometric studies in the literature evaluating the interface between bone and DMLS implants in the long-term...

STATEMENT OF PROBLEM: Dental implants can be essential in the rehabilitation of various cancer defects, but their ideal placement can be complicated by the limited dimensions of the available host bone. Surgical interventions developed to increase the amount of bone are not all predictable or successful and can sometimes be contraindicated. Short dental implants have been suggested as an alternative option in sites where longer implants are not possible. Whether they provide a successful treatment option is unclear...

Surface functionalization by siRNA is a novel strategy for improved implant osseointegration. Gene delivery system with safety and high transfection activity is a crucial factor for siRNA-functionalized implant to exert its biological function. To this end, polyethylene glycol (PEG) and polyethylenimine (PEI) dual-functionalized graphene oxide (GO) (nGO-PEG-PEI) may present a promising siRNA vector. In this study, nano-sized nGO-PEG-PEI was prepared and optimized for siRNA delivery. Titania nanotubes (NT) fabricated by anodic oxidation were bio-modified with nGO-PEG-PEI/siRNA by cathodic electrodeposition, designated as NT-GPP/siRNA...

With the increase in numbers of joint replacements, spinal surgeries, and dental implantations, there is an urgent need to combat implant-associated infection. In addition to stringent sterile techniques, an efficacious way to prevent this destructive complication is to create new implants with antimicrobial properties. Specifically, these implants must be active in the dental implant environment where the implant is bathed in the glycoprotein-rich salivary fluids that enhance bacterial adhesion, and propagation, and biofilm formation...

The effect of various instruments on titanium dental implant surfaces was evaluated. Furthermore, a clinical guideline was developed regarding the diagnosis, prevention and treatment of peri-implant diseases. Air abrasive devices appear to be the most suitable meachnical instruments to remove biofilm from implant surfaces. From the available chemotherapeutica, (citric)acid and hydrogen peroxide seem to have the best potential. Regular controls and meticulous maintenance from both the patients and dental care professionals are mandatory to avoid problems...

We have previously developed the "alkali and heat treatment" method to confer bioactivity (bone-bonding ability) to titanium metal (Ti). As strontium (Sr) and magnesium (Mg) ions reportedly promote osteoblastic cell proliferation and differentiation and accelerate bone formation, we improved this method to induce the release of Sr (Sr-Ti) or Mg (Mg-Ti) ions from Ti in a previous study. Here, we evaluated the bioactivity of these novel surface treatments, Sr-Ti and Mg-Ti. In vitro evaluation of cell viability, expression of integrin β1, β catenin, and cyclin D1, osteogenic gene expression, alkaline phosphatase activity, and extracellular mineralization using MC3T3-E1 cells revealed that Sr-Ti and Mg-Ti enhanced proliferation and osteogenic differentiation...

BACKGROUND: The topographical features on the surface of dental implants have been considered as a critical parameter for enhancing the osseointegration of implants. In this work, we proposed a surface obtained by a combination of shot blasting and double acid etching. The double acid etching was hypothesized to increase the submicron topography and hence further stimulate the biological properties of the titanium implant. METHODS: The topographical features (surface roughness and real surface area), wettability and surface chemical composition were analyzed...

INTRODUCTION: During osseointegration process, the presence of an inflammatory event could negatively influence the proper osteogenetic ability of the implant surface. In order to reduce this possibility, an implementation of angiogenetic event through the release of Vascular Endothelial Growth Factor (VEGF) can be a tool as co-factor for osteoblastic differentiation. In this paper, novel dental implant surfaces enriched with VEGF have been tested. MATERIAL AND METHODS: The ability of VEGF-enriched titanium implants to improve the osteogenetic properties of Mesenchymal stem cells (MSC), also in the presence of an inflammatory environment, have been in vitro tested...

Peri-implantitis has been described as progressive crestal bone loss around a dental implant. The condition is poorly understood, and is challenging to manage; it is commonly and widely attributed to issues with the implant, the implant surface, surgical technique and oral hygiene. The effect of prosthodontic stages of treatment on the postoperatively established state has not been adequately investigated. It is the authors' contention that the manner in which the implant is restored contributes significantly to prognosis and peri-implant disease experience, and that the role of prosthodontic aspects of treatment in the causation of peri-implantitis may be seriously underestimated...

Digital manufacturing, all-ceramics, and adhesive dentistry are currently the trendiest topics in clinical restorative dentistry. Tooth- and implant-supported fixed restorations from computer-aided design (CAD)/computer-aided manufacturing (CAM)-fabricated high-strength ceramics-namely, alumina and zirconia-are widely accepted as reliable alternatives to traditional metal-ceramic restorations. Most recent developments have focused on high-translucent monolithic full-contour zirconia restorations, which have become extremely popular in a short period of time, due to physical strength, CAD/CAM fabrication, and low cost...

BACKGROUND: The longitudinal clinical outcomes over decades contribute to know potential factors leading to implant failure or complications and help in the decision of treatment alternatives. METHODS: The cases of all patients who received dental implants treated with titanium plasma-sprayed surfaces and whose prostheses were set in the period 1984-1990 at seven private practices were retrospectively analyzed. The cumulative survival rate, the cumulative incidence of peri-implantitis, and the complication-free prosthesis rate were calculated with Kaplan-Meier survival curves, and the factors' influence on implant survival rate and the incidence of peri-implantitis were determined by a single factor in univariate analyses and multivariate analyses...

The increasing use of dental implants rather than fixed cantilever bridges for standard dental restorations has led to the development of multiple materials in this field. The goal in modern dentistry in recent years has been to achieve results in implantology that match the natural dentition in esthetics and function. Constant efforts have been made to achieve a perfect emergence profile, and to individualize the surrounding periimplant soft tissue. Powder-free digital scanning is now possible, which allows for the computer-assisted design/computer-assisted manufacturing (CAD/CAM) of ready-to-fit customized immediate implant abutments in various appropriate materials...
