PURPOSE With the significance of stable adhesion of alveolar bone and peri-implant soft tissue on the surface of titanium for successful dental implantation procedure, the purpose of this study was to apply microgrooves on the titanium surface and investigate their effects on peri-implant cells and tissues. METHODS Three types of commercially pure titanium discs were prepared; machined-surfac...

Although titanium remains as the prevalent material in dental implant manufacturing new zirconia-based materials that overcome the major drawbacks of the standard 3Y-yttria partially-stabilized zirconia (Y-TZP) are now emerging. In this study, a new ceramic nanocomposite made of alumina and ceria-stabilized TZP (ZCe-A) has been used to produce dental implants with the mechanic and topographic c...

Metallic materials are the basis of dental materials science, which is an important part of dentistry. As a result of their good mechanical properties and some biological properties, metals are widely used in oral rehabilitation of dentition and mandibular defects, orthodontic and dental implants, as well as in the equipment for dental operations. Commonly used metals include nickel chromium, c...

Yellow nail syndrome (YNS) is characterized by the triad of nail changes, lymphedema and respiratory tract involvement. Several hypotheses have been postulated to explain the findings in YNS including lymphatic drainage abnormalities along with microvasculopathy. The most recent hypothesis, proposed by Berglund and Calmark [Biol Trace Elem Res 2011; 143: 1–7], suggests a role of titanium dioxid...

Zirconia is now favored over titanium for use in dental implant materials because of its superior aesthetic qualities. However, zirconia is susceptible to degradation at lower temperatures. In order to address this issue, we have developed modified zirconia implants that contain tantalum oxide or niobium oxide. Cells attached as efficiently to the zirconia implants as to titanium-based material...

Peri-implantitis is an inflammatory disease that results in the destruction of soft tissue and bone around the implant. Titanium implant corrosion has been attributed to the implant failure and cytotoxic effects to the alveolar bone. We have documented the extent of titanium release into surrounding plaque in patients with and without peri-implantitis. An in vitro model was designed to represen...

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...

This review paper investigates the possible transformation of endosseous dental implant, primarily from the current osseointegrated to the future ligament anchored implant within which a new class of implants with enhanced feature of “neuro-ligament integration” may appear. Endosseous dental implants used presently to replace missing teeth get fused with bone but they do not have any periodonta...

A prospective study was conducted in which 21 patients received a mandibular implant-supported overdenture. Eighty-four ITI screw-type implants were placed in the interforaminal area of the mental symphysis (4 implants per patient). Immediately after implant placement, a U-shaped gold or titanium bar was fabricated and implants were loaded with an implant-retained overdenture. Of 21 patients tr...
