METHOD FOR MANUFACTURE OF INDIVIDUAL IMPLANT FOR SKULL BONE DEFECTS REPLACEMENT Russian patent published in 2018 - IPC A61F2/28 

FIELD: medicine.

SUBSTANCE: three-dimensional computer modelling of the required implant geometry is performed on a three-dimensional computer skull model directly in the area of the defect, which it must cover. The necessary structure, fixing holes and orientation marking of the implant sides are modelled. Three-dimensional printing of the implant using a three-dimensional printer by direct laser sintering or electron beam melting of fine titanium powder or its alloys is performed. Thermal treatment of the implant is carried out by smooth heating up to 500-1000°C in a vacuum or argon atmosphere with exposure at the required temperature from 1 to 6 hours, depending on the required physico-mechanical properties, phased ultrasonic cleaning in distilled water, neutral, alkaline and acidic media and repeated washing in an ultrasonic bath with distilled water for 30-60 minutes are performed.

EFFECT: method allows to create an implant with sufficient strength and precisely corresponding to the individual features of the skull structure of the patient.
