background: titanium (ti) implants are commonly coated with hydroxyapatite (ha). however, ha has some disadvantages such as brittleness, low tensile strength and fracture toughness. it is desirable to combine the excellent mechanical properties of zro2 and the chemical inertness of al2o3 with respect to the purpose of this project which was coating ti implants with ha-zro2-al2o3 to modify the s...

titanium (ti) is one of the most widely used biomaterials for manufacturing dental implants. the implant surface properties strongly influence osseointegration. the aim of the present study was to in vitro investigate the characteristics of ti dental implants in terms of mutagenicity, hemocompatibility, biocompatibility, osteoinductivity and biological safety. the ames test was used to test the...

OBJECTIVES This study evaluated cytocompatibility and osseointegration of the titanium (Ti) implants with resorbable blast media (RBM) surfaces produced by grit-blasting or XPEED(®) surfaces by coating of the nanostructured calcium. MATERIAL AND METHODS Ti implants with XPEED(®) surfaces were hydrothermally prepared from Ti implants with RBM surfaces in a solution containing alkaline calcium....

PURPOSE The aim of the present study was to systematically evaluate the marginal bone loss (MBL), success, and survival of zirconia (Zi) implants and compare them with the widely studied titanium (Ti) implants. MATERIALS AND METHODS An electronic and manual literature search of several databases was performed by two independent reviewers for articles up to July 2015 that reported the use of Z...

PURPOSE To test the mechanical stability and histologic osseointegration under load-bearing conditions of 2 different materials, pyrocarbon (Py) and titanium (Ti), in a rabbit model. METHODS Proximal interphalangeal implants (9 Ti, 8 Py) were placed into rabbit knees and the animals were killed after 3 months. Subsidence was assessed by monthly x-rays. Mechanical stability was measured with a...

BACKGROUND A worrying correlation which seems to be overlooked by clinicians is allergic reactions to titanium (Ti) in patients with dental implants. PURPOSE The aim of the present review study was to assess whether or not Ti sensitivity is associated with allergic reactions in patients with dental implants. MATERIALS AND METHODS To address the focused question "Can Ti cause allergic reacti...

Reports have documented titanium (Ti) hypersensitivity after dental implant treatment. Alternative materials have been suggested including zirconia (Zr) ceramics, which have shown predictable osseointegration in animal studies and appear free of immune responses. The aim of the research was to investigate the bone-to-implant contact (BIC) of one-piece Zr, compared with one-piece Ti implants, pl...

BACKGROUND The development of novel biomaterials able to control cell activities and direct their fate is warranted for engineering functional bone tissues. Adding bioactive materials can improve new bone formation and better osseointegration. Three types of titanium (Ti) implants were tested for in vitro biocompatibility in this comparative study: Ti6Al7Nb implants with 25% total porosity used...
