A bioactive and anti-bacterial nano-sized zirconium phosphate/GO (nZrP/GO) composite: Potential use as a coating for dental implants?

Objective: Dental implants fabricated from titanium have several limitations and therefore, alternative materials that fulfil the criteria of successful dental implant (bioactivity and anti-bacterial activity) need to be considered. Polyether ether ketone (PEEK) has been suggested to replace titanium implants. However, this material needs surface modification to meet the appropriate criteria.

Polyether ether ketone coated with nanohydroxyapatite/graphene oxide composite promotes bioactivity and antibacterial activity at the surface of the material.

Polyether ether ketone (PEEK) is considered an alternative material for manufacturing dental implants. However, PEEK lacks bioactivity and antibacterial action. In a series of experiments designed to enhance the surface properties of PEEK, we present a nanohydroxyapatite (nHA) and graphene oxide (GO) composite as a coating for PEEK-based dental implants to improve biological properties and antibacterial action.

A novel bioactive glass/graphene oxide composite coating for a polyether ether ketone-based dental implant.

Polyether ether ketone (PEEK) is a biocompatible material that lacks antimicrobial activity and bioactivity; therefore, is not appropriate for use as a dental implant. To overcome these deficiencies, a novel composite coating of bioactive glass and graphene oxide was prepared. PEEK discs were polished, cleaned, and the surface treated with sulfuric acid for 15 min.

MgF- containing glasses as a coating for titanium dental implant. I- Glass powder.

Bioactive glasses can be used to coat titanium implants to promote osseointegration. However, incorporating elements such as magnesium, zinc and fluoride into bioactive glasses might have a negative effect on bioactivity or the coefficient of thermal expansion of the glass. In this study, the impact of substituting MgO for CaO on physical properties and bioactivity of glass containing 1 mol % MgF was assessed.

Pyogenic granuloma: Clinicopathological and treatment scenario.

Background: Oral pyogenic granuloma is a soft-tissue lesion of the oral mucosa. This lesion has a tendency to reoccur after surgical excision.

Materials And Methods: A total of 28 patients underwent surgical excision of pyogenic granuloma in the period from September 2014 to May 2016.
