“…Currently, PEEK is introduced for dental applications, such as transitional abutments 9) , healing abutments 10) and dental clasps 11) . It can also be used as an alternative rigid material for removable partial denture prosthesis frameworks 12) and fixed dental prostheses 13) due to its non-metallic color, low weight and high strength. However, greyish color and opacity of PEEK are the main disadvantages, and they limit its usage.…”

This study evaluated the effect of surface pretreatments on resin composite bonding to polyetheretherketone (PEEK). Four groups of surface pretreatment (no pretreatment, etched with 98% sulfuric acid, etched with piranha solution and sandblasting with 50 µm alumina) were performed on PEEK. Surface roughness, Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) analysis were examined. Shear bond strength (SBS) and interface characteristics were also evaluated after the specimens were bonded with resin materials. Two-way ANOVA analysis revealed significance on two main effects and interactions. Tukey's multiple comparisons test showed that the SBS of resin composite on PEEK were the highest in the group etched with 98% sulfuric acid and bonded with Heliobond ® (p<0.05). All pretreatments produced similar spectra of FTIR patterns. SEM demonstrated porosities and pitting from chemical etching, which suggested a significant influence on the adhesion between PEEK and resin materials.

“…Unlike metal, PEEK is biocompatible and has a natural tooth-colored appearance, hence its widespread use in implants, provisional abutments, implant supported bars, or clamp materials in the field of removable dental prostheses and maxillary obturator prostheses [9][10][11]. PEEK also offers an alternative to orthodontic wires for reasons of improved aesthetics, allergies to metals, and interference of metals with TC [10].…”

“…The biocompatibility, flexural bone modulus, resistance to cracking, ease of polishing, and machinability of PEEK-OPTIMA (reinforced poly-ether-etherketone), allows its use as a material in the palatal section of maxillary obturator prostheses in patients with large oral-nasal defects [9].…”

“…To achieve good bioactivity, many modifications for pure PEEK have been proposed [1,[3][4]9,14,[17][18][19][20][21][22]. It has been suggested that the incorporation of nanosized particles, such as hydroxyfluorapatite (n-FHA), could inhibit bacterial adhesion and accelerate bacterial death, in order to reduce the risk of peri-implantitis [14][15][16][17][18][19][20][21][22].…”

“…The material has also been used in orthopedic implants, and may be ideal for articulating implants. In the area of dentistry, CFR-PEEK is used in the palatal section of maxillary obturator prostheses in patients with large oral-nasal defects [1,[3][4]9,19]. The high fatigue resistance and toughness of CFR-PEEK could minimize the risk of implant fracture [20].…”

Introduction: Thermoplastic polymers have many potential uses in medicine and dentistry as an alternative to the commonly used titanium. Due to several advantages of these materials, metal-free restorations are performing an important role in current medical therapies. The aim of this review was to evaluate Polyetheretherketone (PEEK) as an alternative material to titanium in medical and dental clinical cases. Methods:Original scientific articles published in Medline-Pubmed database were electronically searched to accomplish the objectives of the study. Only articles published in English were included from 2000 to present using a variety of keywords in combination. The studies relevant to our review were analysed and compared. Conclusions:The literature suggests that PEEK offers an alternative to titanium, especially in cases of orthopaedics and trauma. Its properties make it an interesting material in oral implantology to be performed with CAD-CAM. Further studies are required to obtain sufficient scientific evidence to enable its uses as a permanent material.

Functionalized Cortical Bone‐Inspired Composites Adapt to the Mechanical and Biological Properties of the Edentulous Area to Resist Fretting Wear

et al. 2023

Dental implants with long‐term success of osseointegration have always been the goal, however, difficulties exist. The accumulation of fretting damage at the implant–bone interface often gets overlooked. Commonly used titanium is approximately 7‐fold harder and stiffer than cortical bone. Stress shielding caused by the mismatching of the elastic modulus aggravates fretting at the interface, which is accompanied by the risk of the formation of proinflammatory metal debris and implant loosening. Thus, the authors explore functionalized cortical bone‐inspired composites (FCBIC) with a hierarchical structure at multiple scales, that exhibit good mechanical and biological adaptivity with cortical bone. The design is inspired by nature, combining brittle minerals with organic molecules to maintain machinability, which helps to acquire excellent energy‐dissipating capability. It therefore has the comparable hardness and elastic modulus, strength, and elastic‐plastic deformation to cortical bone. Meanwhile, this cortical bone analogy exhibits excellent osteoinduction and osseointegration abilities. These two properties also facilitate each other to resist fretting wear, and therefore improve the success rate of implantation. Based on these results, the biological–mechanical co‐operation coefficient is proposed to describe the coupling between these two factors for designing the optimized dental implants.
