METHOD FOR DESIGNING CUSTOMIZED IMPLANTS FOR PATIENTS WITH BONE DEFECTS AND SERVER FOR PROVIDING THEREOF

Absstract of: WO2025239593A1

A method for designing a patient-customized implant for a bone defect site comprises the steps of: extracting, by a processor, a 3D image of a bone defect site; designing a 3D shape-based implant on the basis of the extracted 3D image of the bone defect site; calculating the direction and magnitude of partial loads received when the designed 3D shape-based implant is inserted into the bone defect site; designing, on the basis of the direction and magnitude of the partial loads, porosity of the designed 3D shape-based implant, the shape of solid metal, and the degree of porosity; and displaying, to a user, the designed 3D shape-based implant on the basis of the determined porosity, shape of solid metal, and degree of porosity.

치과 기구의 자동 마킹을 위한 기법

Absstract of: MX2025011659A

The present disclosure discusses techniques for marking a dental appliance. A dental model and dental appliance are positioned onto a conveyor tray, which is transported to a scan station. The dental model and conveyor tray each include an identifying code. The scan station includes a camera and barcode reader to read the identifying codes on the dental model and conveyor tray, and these codes are associated with one another. The conveyor tray then moves to a marking station where a barcode reader reads the code on the conveyor tray, and then marks the dental appliance with the appropriate marking.
