Systematic Review Evaluating the Influence of Veneering Design on the Clinical Outcome of All‐Ceramic Implant‐Supported 3–4 Units and Full Arch Fixed Dental Prostheses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To systematically assess survival, failure, and complication rates of all‐ceramic implant‐supported monolithic and micro‐veneered FDPs (i‐FDPs) in partially/completely edentulous patients compared to veneered restorations. Materials and Methods An electronic search identified prospective clinical studies on all‐ceramic i‐FDPs with at

Osseointegration of Antimicrobial Acrylic Bone Cements Modified with Graphene Oxide and Chitosan

Applied Sciences, 2020
Acrylic bone cement (ABC) is one of the most used materials in orthopedic surgery, mainly for the fixation of orthopedic implants to the bone. However, ABCs usually present lack of biological activity and osseointegration capacity that leads to loosening

Assessment of fit accuracy and retentive strength of additively manufactured zirconia crowns luted to Ti‐base abutments with different resin cements: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study investigated the influence of cement gap size on the marginal and internal fit, and cement gap size and type on retention of additively manufactured zirconia (AM‐Z) crowns on titanium bases (Ti‐base). Materials and Methods A total of 135 zirconia crowns were designed with three different cement gap sizes: 20 µm, 30 µm, and ...

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...

Effect of non-contact induction heating on HA coatings and bone cement, an ex vivo study [version 2; peer review: 2 approved, 1 approved with reservations]

F1000Research
Background Prosthetic joint infection is a serious complication that can arise after total joint replacement surgery. When bacteria colonise an orthopaedic implant, they form biofilms that protect them from their environment, making them difficult to ...
