PROCÉDÉ DE FABRICATION D'UNE SUSPENSION DE ZIRCONE PERMETTANT DE FORMER UNE SURFACE POREUSE SUR UN IMPLANT ET UNE COURONNE EN CÉRAMIQUE, ET PROCÉDÉ DE FABRICATION D'IMPLANT L'UTILISANT
The present invention relates to a method for manufacturing a zirconia slurry for forming a porous surface on a ceramic implant and crown, and a method for manufacturing an implant using the same. According to the present invention, a predetermined ball mill device is used to obtain a zirconia slurry having a nano-particle size in an improved method compared to existing methods. Also, the zirconia slurry produced by the improved method is applied to a specific object and dried to form a porous surface and thereby actively enhance the bonding force between an abutment and a crown or between a laminate and a tooth of a patient, and maximize the biointegration of an implant itself. Thus, the contact surface between the implant material and bone tissue is improved by enabling bone fiber tissue of the alveolar bone to permeate into the implant and grow. More specifically, the method is characterized by comprising: a zirconia crushing step (S10) for putting zirconia, a foaming agent and an organic binder into a ball mill device, and crushing same while stirring； a carbon powder oxidation step (S20) for heating zirconia powder mixed with the foaming agent to 1200 to 1800°C, oxidizing such that the concentration of carbon powder is 10 to 40 wt%, and forming a porous surface on each particle； and a degreasing process step (S30) for removing the organic binder added to the mixture, while preparing a zirconia solution by adding a dispersing agent and a solvent to the zirconia powder having the porous surface.La présente invention concerne un procédé de fabrication d'une suspension épaisse de zircone permettant de former une surface poreuse sur un implant et une couronne en céramique, et un procédé de fabrication d'un implant l'utilisant. Selon la présente invention, un dispositif de broyeur à boulets prédéterminé est utilisé afin d'obtenir une suspension épaisse de zircone ayant une taille de nanoparticules dans un procédé amélioré par rapport aux procédés existants.
