Subtractive computer-aided design and manufacturing technique is revolutionary in dentistry providing lots of advantages such as accuracy, time and labour saving, prevention of cross-infection. Because this technique causes waste of more materialthan used for the final restoration, it has high cost. Requirement of cost reduction led to development of additive manufacturing technique. This technique supplants traditional subtractive computer aided design and manufacturing technique enabling manuf...

Auricular, nasal, orbital, and surrounding defects prevent people fitting into society and sometimes cause psychological problems for the patients. Facial prostheses help the patient to get better psychologically and join the social life. For natural appearance, facial prostheses are required to be similar with surrounding skin with regard to color and translucency. The aim of this study is the visual evaluation of computer aided digital method used for color matching between silicone facial pro...

Facial prostheses offer an alternative treatment which improves quality of life for the patients with auricular, orbital, and nasal defects. Silicone elastomers used for fabrication of facial elastomers are required to be similar with surrounding skin with regard to color and translucency, and hardness. The aim of this study is to evaluate the effect of facial prosthetic silicone elastomer thickness on the translucency and hardness of the material. Disk shaped silicone elastomer specimens 15 mm ...

The present study is based on the analysis of the differential treatment granted to microenterprises, small businesses and individual microentrepreneurs, treated as small businesses,in the acquisition of direct, indirect, autarchic and foundational Public Administration. The constitutional principle of isonomy, which guarantees this treatment, and the ways its effectiveness is sought through the 7 (seven) existing mechanisms that privilege small companies in the bidding process are analyzed. Fur...

The complex biomechanics and morphology of the femur proximal epiphysis are presented. This specific region in human femur is characterized by a high flexibility compared to that of other primates, since evolved lighter and longer due to the human verticalposition and more balanced loading. The nature and fine morphology of the femur head and its structural behavior have been investigated. Isotropic and orthotropic trabecular structures, which are not present in other primates, have been associa...

All synthetic and natural materials to be used in biomedical applications that involve the contact with human body need to be investigated for their physical and chemical modification induced by the human physiological fluids contact and sorption. The development and testing in human physiological equivalent fluids of new hybrid biomaterials are presented. The role of water and its equilibrium modification in the human physiology is discussed and the swelling and sorption behavior in the physiol...
