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.

Effect of Occlusal Adjustment and Subsequent Repolishing on the Translucency Parameter, Contact Angle, and Flexural Strength of Different Types of Glazed Monolithic Zirconia. [PDF]

J Esthet Restor Dent
ABSTRACT Objectives This study evaluated the effects of material and surface condition (glazed vs. polished after simulated occlusal adjustment) on translucency parameter, contact angle, and flexural strength of four monolithic zirconia. Materials and Methods Disk‐shaped specimens (n = 80, Ø12 × 1 mm) were fabricated from four monolithic zirconia ...

Splinted and Nonsplinted Crowns with Different Implant Lengths in the Posterior Maxilla by Three‐Dimensional Finite Element Analysis

Journal of Healthcare Engineering, Volume 2018, Issue 1, 2018., 2018
The aim of this study was to evaluate stress distribution in the implants/components and bone tissue for splinted and nonsplinted prostheses with different lengths of implants using three‐dimensional finite element analysis. Six models from the posterior maxillary area were used in simulations.
