Titanium Coated with Graphene and Niobium Pentoxide for Biomaterial Applications

International Journal of Biomaterials, Volume 2022, Issue 1, 2022., 2022
Graphene and niobium oxide are used in biomaterial coatings. In this work, commercially pure titanium (cp Ti) was coated with graphene oxide (GO), niobium pentoxide (Nb2O5), and a mixture of both materials (NbGO) by the electrochemical deposition method. The surface morphology, roughness, wettability, and degradation of coated and uncoated samples were

Galvanic Corrosion of Ti Dental Implants Coupled to CoCrMo Prosthetic Component

International Journal of Biomaterials, Volume 2021, Issue 1, 2021., 2021
Dental implant systems are composed of an implant, prosthetic components, and a crown. Since the implants are made of commercially pure Ti (cp Ti) and prosthetic components are often made of Ti and CoCrMo alloys, a galvanic couple between these two devices may lead to galvanic corrosion, ions release, and even loss of the implant.

A Prosthetic and Surgical Approach for Full‐Arch Rehabilitation in Atrophic Maxilla Previously Affected by Peri‐Implantitis

Case Reports in Dentistry, Volume 2021, Issue 1, 2021., 2021
Rehabilitation of atrophic maxilla with dental implants is still a challenge in clinical practice especially in cases of alveolar bone resorption due to peri‐implantitis and pneumatization of the maxillary sinuses. Several surgical approaches have been employed to reconstruct the lost tissues allowing the proper tridimensional position of the implants.
