METIM – Design of a Methodology and its Verification for the Measurement of Selected Parameters of Ti Implants in the Manufacturing Process
Návrh metodiky a jej overenie pre meranie vybraných parametrov Ti implantátov vo výrobnom procese
Program: APVV
Duration: 1.7.2023 – 30.6.2027
Project leader: RNDr. Hain Miroslav, PhD.
Annotation: The project focuses on the development and application of measurement and non-destructive testing methods inthe manufacturing of titanium dental implants. Dental implants are medical devices that have to comply with thetechnical requirements given by regulation of the European Parliament and Council EU 2017/745 from 5 Apr 2017.Under this regulation, among other obligations, the manufacturer must ensure that these devices are safe andeffective and do not compromise the clinical condition or patients safety. The dental implants should also meet ahigh level of health and safety protection, taking into account the generally accepted state of the art in science andtechnology. In this project we will address the requirements related to the design and manufacturing and inparticular: the compatibility of the different parts of the device, the influence of processes on the properti es of thematerials, the mechanical properties of the materials used such as strength, ductility, resistance to wear andfatigue, the properties of the surfaces, and confirmation that the device meets all defined physical specifications aswell as the identification of contaminants in the manufacturing process. To ensure these requirements, we intend touse state-of-the-art measurement methods such as X-ray microtomography (microCT), scanning electronmicroscopy (SEM), optical measurement of surface roughness, SQUID magnetometry. Since the abovemeasurement methods are time consuming and do not allow their full application in the production, the solution willalso include the design of effective methods of statistical quality control, which will be applied at the manufacturerof dental titanium implants MARTIKAN, s.r.o. The objectives of the proposed project correlate with the Researchand Innovation Strategy for Smart Specialisation of the Slovak Republic 2021-2027 (SK RIS3 2021+), while theyaffect two defined domains, namely Innovative Industry for the 21st Century and Healthy Society.
CT modeling and morphological analysis of the postcranial region of extinct and current lizards and their relatedness based on new morphological data
CT modelovanie a morfologická analýza postkraniálneho regiónu vyhynutých i súčasných jašterov a ich príbuznosť založená na nových morfologických dátach
Program: VEGA
Duration: 1.1.2021 – 31.12.2023
Project leader: RNDr. Hain Miroslav, PhD.
Annotation: The cranio-cervical and brachial regions, together with the limbs, are not only really important, but all their partsform well-described modular units that can provide a model system for assessing interactiontheir individual functions, their development and phylogenetic history on the morphology of adults. Their understanding withusing a new approach that integrates detailed morphological analysis with modern computer methods(biomechanical simulations, 3D morphometry and iodine enhanced CT imaging of soft tissues, phylogeneticanalysis) is therefore crucial. Due to the different lifestyles and the extreme range of sizes and morphologiesbody, squamates provide an ideal model group for detailed integrated cranio-cervical studies,more or less complete loss or reduction of limbs and braids allow to examine the relationship between anatomy,functional morphology, phylogenetic position, lifestyle and development. The study will focus on today\’s,but also fossil lizards (eg from the Messel locality in Germany).
