23 Jul Design production method of dental implantation repair individual tray
Abstract
The invention relates to a design production method of a dental implantation repair individual tray. The design production method comprises: preparing an initial impression, and filling a plaster model; scanning the initial impression or plaster model; transferring the scanning data into a reverse engineering software, and extracting the cloud data of the tissue surface points inside the initial impression mucous membrane folding line; filling the inverted concave region; uniformly amplifying 2-3 mm along the data surface normal direction to obtain a virtual tray inner surface; uniformly thickening 2 mm along the virtual tray inner surface normal direction; reserving an impression rod penetrating hole on the surface of the tray in the implant corresponding region; designing a maxillary virtual tray handle and a mandibular virtual tray handle; and carrying out boundary fusion on the virtual tray inner surface data, the outer surface data and the handle data, storing in the STL format, and producing the edentulous personalized impression tray having the resin material through 3D printing equipment. According to the present invention, the produced dental implantation repair individual tray using the digital designing can replace the traditional hand-made production, and the precision of the opening implantation impression is easily improved.
