مقدمه وهدف : میزان موفقیت مواد بکار رفته در جراحی های بالا بردن کف سینوس ماگزیلا و همچنین ثبات ایمپلنت های قرار گرفته در این نواحی همواره مطرح است لذا این مطالعه با هدف مقایسه ارتفاع استخوان و میزان ثبات ایمپلنت های کاشته شده به طور همزمان با جراحی بالا بردن کف سینوس ماگزیلا با استفاده از مواد bio-oss و nanobone با استفاده از آنالیز فرکانس انعکاسی و تصاویر cbct بود. مواد و روشها : در ابتدا بیم...
Bio-hybrid artificial organs are an attractive concept to restore organ function through precise biological cooperation with surrounding tissues in vivo. However, in bio-hybrid artificial organs, an artificial organ with fibrous connective tissues, including muscles, tendons and ligaments, has not been developed. Here, we have enveloped with embryonic dental follicle tissue around a HA-coated d...
• The design method based on Voronoi was proposed to mimic the characteristics of cancellous bone in human body. Ceramic Digital light processing (DLP) adopted satisfy forming requirements irregular scaffolds. compressive strength scaffolds can be increased by 30% through regulation irregularity. Cell experiments confirmed that structural changes also had influence biocompatibility Ideal requir...
Scanning probe microscope-enabled nanoindentation is increasingly reported as a means to assess the mechanical properties of nanoscale, compliant material volumes such as polymeric films and bio-membranes. It has been demonstrated experimentally that the Hertzian contact model developed for linear elastic materials of semi-infinite thickness fails to accurately predict the nominal elastic modul...
OBJECTIVES Our study aimed to examine not only the incidence but also the impact of noise from two types of total hip replacement articulations: ceramic-on-ceramic and ceramic-on-polyethylene. METHODS We performed a case-controlled study comparing subjective and objective questionnaire scores of patients receiving a ceramic-on-ceramic or a ceramic-on-polyethylene total hip replacement by a si...
Tuning of ion-release capability from bio-ceramic-polymer composites for enhancing cellular activity
A novel hybrid process combining robocasting and starch-consolidation method, enabling the fabrication of ceramic scaffolds with porosity as high 85%, is developed applied to zirconia. This enables a precise control volume size porosity. It also allows its hierarchization over 4 decades length scales up three families: i – macroscopic, from 100 µm 2 mm controlled by design, ii micronic, 70 thro...
