A total of 15 (n=5 per group) bone level implants (Figure 1a) with diameters of 4.7 mm at the shoulder and 3.7 mm at the apex and a length of 16 mm (SCI-BioActive; AlfaGate; KfarQara, Israel) were placed in bone surrogate materials (Figure 1b) differing in density (Solid rigid polyurethane foam, 10 pound per cubic foot (pcf), 20 pcf,

objective: one of the major issues in bone tissue engineering is the design and fabrication of bioactive, bioresorbable porous 3d scaffolds capable of maintaining their structure and integrity over a predictable period of time. one such approach is the fabrication of composite scaffolds. methods: in this study we present fabrication and characterization of novel silk/bioglass-composite scaffold...

Triple-layer omnidirectional reflectors (ODRs) consisting of a semiconductor, a quarter-wavelength transparent dielectric layer, and a metal have high reflectivities for all angles of incidence. Internal ODRs (ambient material's refractive index n >> 1.0) are demonstrated that incorporate nanoporous SiO2, a low-refractive-index material (n = 1.23), as well as dense SiO2 (n = 1.46). GaP and Ag s...

Biomaterials have evolved over the past three decades and are relatively specialized, highly biocompatible, but low-strength dental materials. Bioactive materials can interact with living tissues or systems. The newly emerging bioactive category of has expanded clinical uses in restorative dentistry endodontics. Examples Calcium Silicate containing Mineral Trioxide Aggregate (Portland cement); ...

Different techniques and materials can be used to treat intrabony periodontal defects caused by periodontal diseases. This case report presents an intrabony periodontal defect with bioactive glass and connective tissue graft used as a barrier. Probing depth and clinical attachment gain were reduced at 6 and 12 months post-treatment.
