Abstract:

The project proposes the design, obtaining, and characterization of multifunctional chitosan and collagen sponge-type bioactive dressings with essential oils.

The motivation of the chosen topic resides in the fact that these types of bioactive dressings can be useful for treating superficial wounds such as acne or eschar,

reducing inflammation, a fact demonstrated by various experimental testing methods. Multifunctional bioactive dressings with essential oils are non-invasive

products and can be seen as a good option for people who have adverse reactions to conventional antibiotics.

Abstract:

Main objective of the project is the development of one composite coatings with polymer-based (cellulose acetate, collagen, polylactic acid or chitosan) reinforced with Mg and Mg-substituted hydroxyapatite particles, for biodegradable implants made by Mg-Ca alloy, followed by in vitro cell based tests for evaluating biocompatibility and osseointegration activity. Obtained coated implants will be characterized not just from structural and morphological point of view, but also for mechanical properties and surface properties. Several specific tests for evaluation of the osseointegration will be performed, like study of coating hydrolysis at physiological pH, degradation compounds, flows and proteins retention. After the chosen of best coating material for osseointegration, a commission constituted by independent experts will validate the proposed experimental model. The project objectives are totally feasible, due to the previous experience and results obtained by the project leader and his research team, as well as the equipment available for synthesis, characterization and testing. The project results will be innovative and relevant in relation to the national and international state of the art because the final composite coatings is a new solution from materials point of view, and new coated biodegradable implant will have a better osseointegration, controlled biodegradability and proper mechanical properties during degradation process, like a magic bone (MAGICBONE).

Biocompatible coatings for enhanced bond strength of ceramic to metal in dental restorations Call name: Joint Applied Research Projects - PCCA-2011 call, Type 2

Abstract:

The main scientific objective of this project is to obtain a new variety of high bond nanostructured coatings, based on nc-MeN/a-Si3N4 and nc-MeON/a-Si3N4 nanocomposites (nc-nanocrystalline, a-amorphous, Me – metal (Ti, Zr, Cr or Al), N – nitrogen, O - oxygen), in mono, multilayered and graded structures, with good hardness, high adhesion to metallic and ceramic substrates, low internal stress, high resistance against wear, corrosion and oxidation, high fracture toughness, good biocompatibility to tooth and to oral environment.

In the present project we propose to enhance bond strength of ceramic to metal in dental restorations by inserting novel biocompatible nanocomposite coatings between the metal and ceramics, by means of the cathodic arc technique:

- nanocomposite single layer coatings (nc – MeSiN or nc – MeSiON), where Me is Ti, Zr, Cr or Al,

- nanocomposite mutilayer coatings (nc – MeSiN/MeN and nc – MeSiON /MeN),

- nanocomposite graded MeN/MeSiN/MeSiON coatings.

The scientific expectation is that such coatings enhance the adhesion of ceramic to metallic substrates (NiCr or CoCr alloys), leading to longer service life of the dental restoration. Also, the proposed coatings would effectively prevent the adverse oxidation of NiCr and CoCr alloys and would ensure good biocompatibility in oral environment, having colours close to natural teeth. The great challenges of the project are to obtain a high bond of ceramic to metal and dental restorations with color closed to natural teeth.
