Subperiosteal implants are generally used in the severely resorbed areas, and although dwindling in use, they have shown to be successful treatment options for the edentulous dental patients. We report a case of maxillary subperiosteal implantitis that caused sinusitis. A 59-year-old man was referred to our clinic in March 2003 with a chief complaint of pain and swelling in the bilateral upper ...

Purpose: To synthesize niobium silicate particles (SiNb) and incorporate into resin-based luting agents. Methods: SiNb were synthesized characterized by x-ray diffraction, FTIR spectroscopy, particle size, specific surface area. Luting agents formulated with 50 wt% BisGMA, 30 TEGDMA 20 UDMA. BAPO was used as a photoinitiator in 1mol%. The incorporated the at concentrations of (SiNb50%) or 65% (...

This study visually compared the radiopacity of seven restorative materials (3 resin-modified glass-ionomer cements, 3 polyacid-modified composite resins, and 1 conventional glass-ionomer cement) to a sound tooth structure sample, and an aluminium stepwedge. All hybrid materials were more radiopaque, except for one resin-modified glass-ionomer cement, than both the tooth structure and conventio...

OBJECTIVE Mineral Trioxide Aggregate (MTA) is a calcium silicate cement composed of Portland cement (PC) and bismuth oxide. Hydroxyapatite has been incorporated to enhance mechanical and biological properties of dental materials. This study evaluated physicochemical and mechanical properties and antibiofilm activity of MTA and PC associated with zirconium oxide (ZrO2) and hydroxyapatite nanopar...

PURPOSE The goal of this work was to develop phantoms for the optimization of pre-operative computed tomography (CT) scans of the prostate artery, which are used for embolization planning. METHODS Acrylonitrile butadiene styrene (ABS) pellets were doped with barium sulfate and extruded into filaments suitable for 3D printing on a fused deposition modeling (FDM) printer. Cylinder phantoms were...

AIM To investigate the physical and chemical properties of Portland cement (PC) loaded with alternative radiopacifying materials for use as root-end filling materials in a mineral trioxide aggregate (MTA)-like system. METHODOLOGY Portland cement loaded with barium sulphate, gold and silver/tin alloy was mixed with water, and the physical and chemical properties of the hydrated cements were ev...
