Direct Metallization Using Surface Modification of Thermosetting Polyphenylene Ether Resin Laminate.

Evaluation of polyphenylene ether ether sulfone/nanohydroxyapatite nanofiber composite as a biomaterial for hard tissue replacement

The present work is aimed at investigating the mechanical and in vitro biological properties of polyphenylene ether ether sulfone (PPEES)/nanohydroxyapatite (nHA) composite fibers. Electrospinning was used to prepare nanofiber composite mats of PPEES/nHA with different weight percentages of the inorganic filler, nHA. The fabricated composites were characterized using Fourier transform infrared ...

Randomized controlled split-mouth clinical trial of direct laminate veneers with two micro-hybrid resin composites.

OBJECTIVES This randomized, split-mouth clinical study evaluated the survival rate of direct laminate veneers made of two resin-composite materials. METHODS A total of 23 patients (mean age: 52.4 years old) received 96 direct composite laminate veneers using two micro-hybrid composites in combination with two adhesive resins (Ena-Bond-Enamel HFO: n=48, Clearfil SE Bond-Miris2: n=48). Enamel w...

کاتالیزورهای co-fe-resol/sio2و fe-mn-resol/sio2 با استفاده از روش ساده و ارزان قیمت همرسوبی تهیه شدند. از رزین پلیمری resol در فرآیند تهیه کاتالیزور استفاده شد.

Direct laminate veneers with resin composites: two case reports with five-year follow-ups.

AIM The aim of this report is to present five-year follow-ups of two different applications for the use of direct laminate resin-based composite veneers to improve esthetics. BACKGROUND Defects in the maxillary anterior teeth, such as enamel hypoplasia and peg lateral, can present esthetic challenges. Furthermore, a treatment plan that can be completed in a single appointment is highly desira...
