Dental implants have been a universally accepted option for prosthetic rehabilitation of partially edentulous patients. Titanium implants abutments exhibit a dull grayish hue and give an unnatural appearance. Abutments based on zirconia are one of the alternatives to titanium abutments. To date, few comparative studies have reported on esthetic and biological outcomes of implant-supported resto...
Clark, Paul A., Anthony Rodriguez, D. Rick Sumner, Mohammad A. Hussain, and Jeremy J. Mao. Modulation of bone ingrowth of rabbit femur titanium implants by in vivo axial micromechanical loading. J Appl Physiol 98: 1922–1929, 2005. First published January 7, 2005; doi:10.1152/japplphysiol.01080.2004.—Titanium implants commonly used in orthopedics and dentistry integrate into host bone by a compl...
In recent years the use of titanium implant have received special attention in dentistry. In 1994 an implant clinic has established in Faculty of Dentistry, Tehran University of Medical Science and since then, 289 implants have been placed for 120 patients. In literatures a success rate of 93% and 84% of implants placed in mandible and maxilla respectively, have been reported. The purpose of th...
Titanium plates treated in vitro with a mouthwash containing amine fluoride (100 ppm F-) and another containing zinc-substituted carbonate-hydroxyapatite have been analyzed by scanning electron microscopy and atomic force microscopy to evaluate the modification of the surface roughness induced by treatment with these two different mouthwashes. The treatment with F--based mouthwash produces a ro...
The aim of the present study was to evaluate the gingival connective tissue response to screw-type titanium implants coated with Type I collagen nanofibers, which were prepared using the electrospray deposition method. Implants were immediately inserted into the socket of maxillary first molars after the extraction. Undecalcified sections after 4 weeks implantation were histologically observed....
Titanium micro-mesh implants are widely used in orbital wall reconstructions because they have several advantageous characteristics. However, the rough and irregular marginal spurs of the cut edges of the titanium mesh sheet impede the efficacious and minimally traumatic insertion of the implant, because these spurs may catch or hook the orbital soft tissue, skin, or conjunctiva during the inse...
By means of plasma polymerization, positively charged, nanometre-thin coatings can be applied to implant surfaces. The aim of the present study was to quantify the adhesion of human bone cells in vitro and to evaluate the bone ongrowth in vivo, on titanium surfaces modified by plasma polymer coatings. Different implant surface configurations were examined: titanium alloy (Ti6Al4V) coated with p...
PURPOSE Titanium endosseous implants are becoming increasingly important in dentistry because of their excellent long-term results. However, it has been reported that these implants may lead to higher concentrations of titanium, especially in the lungs and kidneys. The purpose of this study, therefore, was to determine whether CO2 laser-assisted decontamination of exposed implant surfaces is as...
Objectives: To correlate between the different lengths, angles of insertion and mini-implant material find out most retentive combination.
 Materials methods: 48 mini-implants (24 Titanium 24 stainless steel) lengths 6mm, 8mm 1.5 mm diameter were inserted into humerus bone goat at two angulations, 600 900. insert in respective custom made template was confirmed with digital radiographs. Fo...
