20080254201 | Method for Preparing Endosseous Implants with Zircon Dioxide Coating - The method includes the following steps: formulation of liquid, non-gelled and stable precursors by solvolysis of ZV (IV) compounds; precursor deposition on endosseous implant surface; thermal treatment to achieve film densification, in the presence of oxygen, of a complex formed by the said endosseous implant and precursor, to obtain on the implant surface a thin nanocrystalline zirconium dioxide film. | 10-16-2008 |
20090005880 | Method for Preparing Endosseous Implants Anatase Titanium Dioxide Coating - The method includes the following steps: formulation of liquid, non-gelled and stable precursor by solvolysis of Ti(IV) compounds; precursor deposition on endosseous implant surface; thermal treatment to achieve film densification, in the presence of oxygen, of a complex formed by the above mentioned endosseous implant and precursor, to obtain on the implant surface a thin film of nanocrystalline titanium dioxide with good mechanical and chemical stability. The complex above, under a persistent W irradiation modify its surface status conferring a sensible increasing of wettability chemical and biological decontamination. | 01-01-2009 |
20090035376 | Stem cells obtained from pulp of deciduous or permanent teeth and of dental germ, able to produce human bone tissue - In this invention is described a method that foresees the isolation of a new subpopulation of stem cells derived form dental pulp, whose differentiation is osteoblasts lead to the subsequent production and employment of a bone tissue, called LAB (Living Autologous Bone). Specifically, the invention describes: 1) the isolation of stem cells from the pulp of deciduous and permanent teeth and of dental germs, obtained from human subjects; 2) the growth of these cells in vitro, under specific conditions that allow the isolation of a cellular sub-population, which, after differentiation in osteoblasts, is able to produce in vitro an extracellular matrix, identical to that detectable in bone tissue; 3) the use of this selected and differentiated cell population in order to produce autologous bone tissue in vitro, containing vital osteoblasts; 4) the preservation of the LAB under conditions which guarantee cellular vitality; 5) the use of the LAB in donor patients to reconstruct bone tissue, as required in the daily practice in dentistry, maxillo-facial surgery and orthopedics. | 02-05-2009 |
