Polyetheretherketone (PEEK) has been suggested as an alternative to replace titanium as a dental implant material. However, PEEK's bioactivity and osseointegration are debatable. This review has systematically analyzed studies that have compared PEEK (or PEEK-based) implants with titanium implants so that its feasibility as a possible replacement for titanium can be determined. The focused question was: “Are the bioactivity and osseointegration of PEEK implants comparable to or better than titanium implants?” Using the key words “dental implant,” “implant,” “polyetheretherketone,” “PEEK,” and “titanium” in various combinations, the following databases were searched electronically: PubMED/MEDLINE, Embase, Google Scholar, ISI Web of Knowledge, and Cochrane Database. 5 in vitro and 4 animal studies were included in the review. In 4 out of 5 in vitro studies, titanium exhibited more cellular proliferation, angiogenesis, osteoblast maturation, and osteogenesis compared to PEEK; one in vitro study observed comparable outcomes regardless of the implant material. In all animal studies, uncoated and coated titanium exhibited a more osteogenic behavior than did uncoated PEEK, while comparable bone-implant contact was observed in HA-coated PEEK and coated titanium implants. Unmodified PEEK is less osseoconductive and bioactive than titanium. Furthermore, the majority of studies had multiple sources of bias; hence, in its unmodified form, PEEK is unsuitable to be used as dental implant. Significantly more research and long-term trials must focus on improving the bioactivity of PEEK before it can be used as dental implant. More comparative animal and clinical studies are warranted to ascertain the potential of PEEK as a viable alternative to titanium.

Bone Response

Introduction: Dental implants have become more common treatment for replacing missing teeth. Titanium and zirconia have been widely applied as dental implant material because of their excellent biocompatibility and biomechanics properties. However, they are lack of biologically active surface that encourages osseointegration and their mechanical properties significant different from enamel and dentin value. Carbonate apatite Ca10(PO4)x(CO3)y(OH)z  comprises a chemical composition closer to bone and enamel. Calcium phosphate are widely used as biomaterials, their osteoconductive and osteoinductive properties have shown beneficial effect on bone osteogenesis. Geopolymers are ceramic-like inorganic polymers, they have excellent mechanical properties, bioactivity, biocompatibility, suitable for hard tissue prostheses, and environmentally friendly. The aim of the study was to evaluate the initial bone healing in geopolymer-carbonated apatite (CHA) nanocomposites. Methods: Geopolymer-CHA nanocomposites samples were prepared in cylinder of 3 mm diameter and 6 mm thickness and placed in the tibia of eight healthy male breeding New Zealand white rabbits weighing 3.0 to 3.5 kg and 6 month aged. Experimental subjects were randomly assigned to 2 groups for evaluating initial bone healing capability around samples to 14 and 28 days histomorphologically. Wilcoxon test was performed and p<0.05 was considered statistically significant, Minitab software version 13 was used. Result:Granulation tissue, woven, and lamellar bone were analyzed. Day 14 revealed a reactive bone formation, which was characterized by granulation tissue, fibroblasts were in an organized extracellular collagen matrix, osteoblast that directly laid out woven bone contained of immature osteoids, and immature osteocytes were observed. The formation of dense fibrocollagen connective tissue that would be the cartilage, osteoblasts, osteoids, and osteocytes showed more mature while woven bone became denser at day 28.Conclusion: Geopolymer-CHA nanocomposites was a potential dental implant material from mechanical and biological properties point of view.Keywords: Histomorphologically, initial bone response, geopolimer-carbonated apatite nanocomposites, dental implant material

Commercially pure titanium (cpTi) is widely used as dental implant material although it was found that titanium exhibited high modulus of elasticity and the lower corrosion tendency in oral environment. Niobium(Nb) was chosen for this study as an alternative to cpTi implant material due to its bioinert behavior and good elastic modulus and moderate cost in addition to corrosion resistance. This study was done to evaluate the effect of biomimetic coating on the surface properties of the commercially pure titanium and niobium implants by in vitro and in vivo experiments. The in vitro study was involved etching the samples of each material in HCl then soaking in 10M NaOH aqueous solution. These samples were then immersed in a 5 times concentrated simulated body fluid for 14 days. Scanning Electron Microscope, Energy Dispersive X-ray, and X-Ray Diffraction tests were done to analyze surface changes. The in vivo study was done by the implantation of screw-shaped implants (two from each material, uncoated and the other was biomimetically coated) in the tibias of New Zealand rabbits. After 2 and 4 weeks of healing period, 20 rabbits were sacrificed for each period. A removal torque was done for ten animals in each group, whereas the other ten were used for histological testing and histomorphometric analysis with optical microscope.The in vitro experiments showed that the use of 14 days immersion in a concentrated simulated body fluid produced a layer of calcium phosphate on metal surfaces. The removal torque values and new bone formation were increased significantly in Nb than Ti, in coated than uncoated screws, and in 4 weeks than 2 weeks healing periods. The Nb implants had better biomechanical and biological properties than the commercially pure titanium implants and can be used as an alternative dental implant.
