Morphology and Mechanical Properties of Thermoplastic Polyurethane/Colemanite Composites
Ferhat ?en,Seyfullah Madakba?,Emre Ba?turk,Memet Vezir Kahraman 한국고분자학회 2017 폴리머 Vol.41 No.6
The aim of this study was to improve thermal stability, mechanical and surface properties of thermoplastic polyurethane (TPU) with the addition of colemanite. The TPU/colemanite composites having various ratios of TPU and colemanite were prepared. The chemical structure of the prepared composites was investigated by Fourier transform infrared spectroscopy (FTIR). Thermal properties of the samples were evaluated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Mechanical properties of the samples were characterized with stress-strain test. Hydrophobicity of the samples was determined by the contact angle measurements. Moreover, the surface morphology of the samples was investigated by a scanning electron microscopy - energy dispersive spectrometer mapping (SEMEDS). Finally, the obtained results prove that the prepared composites have good thermal, mechanical and surface properties and that they can be used in many applications such as the electronic devices, materials engineering and other emergent.

Purpose: Despite the high success rates of endosseous dental implants, their placement is restricted according to the height and volume of bone available. The use of short or mini dental implants could be one way to overcome this limitation. Thus, this study aimed to compare standard, short, and mini dental implants with regard to associated clinical pa¬rameters and peri-implant crevicular fluid (PICF) levels of cathepsin-K (CTSK), RANK ligand (RANKL), and osteoprotegerin (OPG), after prosthodontic loading. Methods: A total of 78 non-submerged implants (Euroteknika, Aesthetica+2, Sallanches, France) were installed in 30 subjects (13 male, 17 female; range, 26–62 years) who visited the clinic of the Periodontology Department, Faculty of Dentistry, Selcuk University. Sam¬pling and measurements were performed on the loading date (baseline) and 2, 14, and 90 days after loading. Assessment of the peri-implant status for the implant sites was per¬formed using the pocket probing depth (PPD), modified plaque index, modified gingival in¬dex, modified sulcular bleeding index, and radiographic signs of bone loss. PICF samples collected from each implant were evaluated for CTSK, RANKL, and OPG levels using the ELISA method. Keratinized tissue and marginal bone loss (MBL) were also noted. Results: Clinical parameters statistically significantly increased in each group but did not show statistical differences between groups without PPD. Although implant groups showed a higher MBL in the upper jaw, only the standard dental group demonstrated a statistically significant difference. At 90 days, the OPG:sRANKL ratio and total amounts of CTSK for each group did not differ from baseline. Conclusions: Within the limitations of this study, both short and mini dental implants were achieving the same outcomes as the standard dental implants in the early period after loading.
