Bioactive Polyaryletherketone Composites

Evaluation of implant bonding strength for PEKK with strontium hydroxyapatite as composite and coating implant material

“…The result of this study mentioned that the force value needed for push out increase as time progress because of bone remodeling and rapid bone formation around the implant, this mean progress in mechanical capacity and osteointegration with time, these results accepted with results of [32], in spite of material and treatment usage in our study differed than the mentioned study. Also this agreed with the study of [33] that been proposed that this improvement was due to an increase in bone-implant contact over time as a result of ongoing bone development and remodeling surrounding the implant throughout the healing process, which improved the mechanical capacity significantly, and agreed with the study of [34] that found increase in the torsional strength began after 4 weeks of unloaded healing and there was a significant increase with time throughout the initial 6 weeks.…”

Effect of Various Treatment Modalities on Surface Characteristics and Shear Bond Strengths of Polyetheretherketone‐Based Core Materials

“…Polyetheretherketone (PEEK) is a member of the polyaryletherketone polymer family, consisting of aromatic benzene molecules connected by functional ether or ketone groups . Pressureless sintering is used to prepare uniform PEEK coatings reinforced by bioglass particles . PEEK is claimed to be an advantageous material for dental applications due to the material's improved mechanical properties and biocompatibility as well as resistance to nearly all organic and inorganic chemicals .…”

PEEK is claimed to be an advantageous material for dental applications due to the material's improved mechanical properties and biocompatibility as well as resistance to nearly all organic and inorganic chemicals . PEEK's use in dentistry is not limited to manufacturing interim abutments, implant‐supported bars, and dental implants—it may also be considered as a material for fixed partial dentures (FPDs) due to the material's improved mechanical properties.…”

Mechanical Implant Material Selection, Durability, Strength, and Stiffness

“…The PEEK HA Enhanced has been shown in animals to result in more direct bone apposition as compared with PEEK bulk material only (Walsh et al 2016). The addition of bioactive materials to PEEK, surface modification techniques, processing techniques for deposition coating of PEEK implants, and functional and mechanical properties of PEEK are well described (Robotti and Zappini 2012;Roeder and Conrad 2012;Poulsson and Richards 2012). It should be noted that the desire to improve the bone ongrowth onto the PEEK implants must not be at the risk of potential failure of the applied coating during anatomical loading or insertion of the implant.…”
