09:15 Piezoelectricity of biopolymers and Wolff’s law in bone
 
  • Following the initial work on wood and bone in 1950’s, the study of piezoelectricity has been developed for biopolymers, polysaccharide, protein, and DNA, and optically active polymers such as poly-L-lactic acid.
  • Recent studies using Piezoresponse Force Microscope have revealed piezo-, pyro-, and ferro- electricity in various biopolymers.
  • Wolff’s law states that bone grows best to support the external stress.
  • It is once assumed that the electrical current due to the piezoelectricity in collagen might be the triggering signal.

10:15 Direct and indirect cell death induced by magnetic hyperthermia
 
  • The use of magnetic nanoparticles (MNPs), when incorporated into cells, provides a way for cell death due to energy supply by the electromagnetic fields under irradiation with radiofrequency waves; this is the field of magnetic hyperthermia (MHT).
  • In vitro cell models show that biodistribution of the nanoparticles constitutes a key factor for the existence of additional Indirect mechanisms that induce cell death of unloaded MNPs cells.
  • This indirect effect exists when the induced cell death occurs without increasing the macroscopic temperature of the cell culture under MHT.
  • This points to a new understanding of relevant biological and molecular mechanisms that trigger the cell death and it paves the way for new cancer therapies based on the use of non-ionizing radiation and nanotechnology as MHT.

11:15 Guided Bone Regeneration in Implant Dentistry
 
  • About 50% of dental implants are placed at sites with bone deficiencies and require therefore a bone augmention procedure.
  • Guided bone regeneration (GBR) is a technique used since 1988 to augment missing bone.
  • While a membrane serves as a physical barrier to keep away soft connective tissue, a bone filler provides mechanical support for the membrane and has many other functions.
  • Autologous bone and bone substitute materials, which are used as bone fillers, have very different properties.

11:45 Unraveling the Biophysical Cues in Cellular Organization
 
  • The differentiation and organization of cells during development occurs under the influence of spatially and temporally controlled soluble signal gradients
  • Macromolecules possess mechanical properties and structure and these attributes are postulated to play an important role in tailoring the biophysical aspects of a cellular environment.

16:15 Resilient Bio-ceramics: Fracture and Reliability of Teeth and Dental Ceramics
 
  • Full ceramic partial dentures are aesthetic and bio-inert replacements, and a widely-accepted standard of care in dentistry nowadays, despite being rather brittle
  • Zirconia ceramics have a superior fracture-resistance than other ceramics due to the so-called transformation toughening mechanism.
  • Based on structure-function relationships we develop hierarchically structured ceramic compounds with the aim to increase their fracture toughness.

16:45 Improvement of wear testing methods for preclinical evaluate of joint implants
 
  • Decades ago wear was identified as one of the major reasons for long term failure of bearing implant designs.
  • Wear testing methods were developed since the introduction of modern joint implants to simulate their wear behavior preclinically.
  • The evolution of these testing methods during the last decade leads to complex simulations of high physiological demands.
  • The intension thereby is to avoid previously observed clinical failure modes and to evaluate material and design improvements of modern implants.

17:15 Titanium Casting and rapid prototyping
 
  • Titanium investment casting performed with the lost wax process meets the standards and demands of modern technology.
  • Cast parts guarantee an optimized use of material, give the ability to create complicated parts, a high level of precision, low wall thicknesses as well as a high level of cost savings on each part.
  • The ideal areas of application for investment castings are those where complicated inside contours, under cuts, hollow structures or bent surfaces cannot be produced or are too complicated to produce with other technologies.
  • Titanium cast parts from Rapid-Prototyping-Models meet the market’s demand for products manufactured to customer specifications within time and cost constraints.

18:00 Public Lecture: Materials and Structural Integrity: Milestone Aircraft Case Histories and Continuing Developments
 
  • Milestone aircraft accidents are discussed with respect to the integrity of conventional metallic structures.
  • These accidents have been especially influential and have caused paradigm shifts in structural integrity design and management.
  • Nowadays, developments in structural integrity have to include the implications of using new alloys, composites, and hybrid structures combining the respective advantages of metallic materials and composites.
