Bonding to Different PEEK Compositions: The Impact of Dental Light Curing Units

This study investigated the impact of different light curing units (LCUs) for the polymerization of adhesive system visio.link (VL) on the tensile bond strength (TBS) of different PEEK compositions. For TBS measurements, 216 PEEK specimens with varying amounts of TiO2 (PEEK/0%, PEEK/20%, PEEK/>30%) were embedded, polished, air abraded (Al2O3, 50 µm, 0.4 MPa), conditioned using VL, and polymerized using either a halogen LCU (HAL-LCU) or a LED LCU (LED-LCU) for chairside or labside application, respectively. After thermocycling (5000×, 5/55 °C), TBS was measured, and fracture types were determined. Data was analyzed using a 2-way ANOVA followed by Tukey–HSD, Kruskal–Wallis H and Mann–Whitney U tests as well as a Chi2-test and a Ciba–Geigy table (p < 0.05). Globally, the light curing units, followed by PEEK composition, was shown to have the highest impact on TBS. The HAL-LCUs, compared to the LED-LCUs, resulted in a higher TBS for all PEEK compositions—without significant differences between chairside and labside units. Regarding the different PEEK compositions, PEEK/20%, compared to PEEK/0%, resulted in a higher TBS when both, HAL-LCUs or LED-LCUs were used for labside application. In comparison with PEEK/>30%, PEEK/20% resulted in a higher TBS after using HAL-LCU for labside application. No significant differences were found between PEEK/0% and PEEK/>30%. HAL-LCU with PEEK/20% for labside application showed a higher TBS than HAL-LCU with PEEK/20% for chairside application, whereas LED-LCU with PEEK/>30% for chairside application showed a higher TBS than LED-LCU with PEEK/>30% for labside application.

“…Quite apart from their use in assay techniques, bioactive nanomaterials have been actively examined for potential future medical treatments and so rapidly did interest in the potential of the new technology develop that it has gave rise to a new field called nanomedicine [130]. Possible applications range from promoting growth of new bone tissue on joint implants [131] to targeted photodynamic therapy of certain cancers [132,133]. Some clinical trial treatments have been conducted, such as the use of a nanoparticle‐based drug Rexin G to treat chemotherapy‐resistant pancreatic tumours [134], and Abraxane, which is now approved for treating certain cancers, as the adverse side effects of Taxol (placlitaxel) are reduced by formulating it with nanoalbumen [135].…”

A few nanoparticle dispersions have been produced for centuries, but it is mainly during the past decade that they have been extensively developed for an amazing range of end uses, some in textile dyeing and finishing but more particularly in a technology now referred to as photonics. The developments in this field are reviewed with particular reference to improved, energy‐saving illuminants, computer and television displays, solar panels and digital communications. Fluorescent nanoparticles, which are now widely employed for sophisticated biomedical diagnostic testing (and possibly in future for treating the diseases themselves), are also described. Many nanoproducts are of almost molecular size and potentially very reactive, which has raised fears about possible, as yet unknown, environmental hazards. This review summarises the results of certain individual toxicity trials and the extensive joint programmes planned in both Europe and America.

“…In fact, several studies on bone implants have revealed positive effect of nanophase surface on osteoblasts. [4][5][6][7][8][9][10][11][12] It is now generally recognized that a nanoscale surface can promote osteoblasts adhesion, proliferation, and function. 4 6 9-13 A systematic investigation on the influence of nanoeffect and also chemistry in cellular experiments can thus help to optimize the chemical composition and surface design of orthopedic materials.…”

The cellular biocompatibility of two types of nanophase hydroxyapatites including nanophase standard hydroxyapatite (n-HA) and nanophase calcium deficient hydroxyapatite (n-CDHA) synthesized by a wet chemical method were assessed using primary cultured osteoblasts. Cytotoxicity of both materials was investigated with L929 cell line. The MTT method was used to evaluate the proliferation of osteoblasts on the third day and ALP activity assay was carried out on the fifth day. SEM was used to observe the morphology of the osteoblasts on the third day. Two types of nanophase hydroxyapatite both showed no cytotoxicity. Higher cell proliferation was observed on n-CDHA than n-HA. At the same time, cells spread more actively on the n-CDHA group. The ALP level of n-CDHA was also significantly higher on the former. Our results show that the n-CDHA is more suitable for osteoblasts growth and is also helpful for ALP synthesis.
