Method of producing adaptive element for dental implantation

A method for producing an adaptive element for dental implantation, comprising steps of:

• obtaining, by a scanning equipment, images of a target tooth of a patient;
• creating, by a processing device, a three-dimensional (3D) virtual model of the target tooth based on the images of the target tooth, the 3D virtual model of the target tooth including a crown part and a root part connected to the crown part;
• obtaining, by the processing device, a boundary curve between the crown part and the root part on the 3D virtual model of the target tooth;
• defining, by the processing device, a cutting line on the root part of the 3D virtual model of the target tooth in a manner that the cutting line is perpendicular to a vertical axis of the 3D virtual model of the target tooth and is spaced apart from the boundary curve;
• extracting, by the processing device, a sub-model from the 3D virtual model of the target tooth, with reference to the boundary curve and the cutting line;
• by the processing device, forming a tubular model from the sub-model by removing all that corresponds to the crown part and by hollowing out the sub-model such that the tubular model has a predetermined thickness in radial directions transverse to the vertical axis;
• and
• producing, by a 3D forming equipment, the adaptive element according to the tubular model,
• wherein the step of defining a cutting line includes:
• defining, as the cutting line, a line that is parallel to and spaced apart by a predetermined distance from a tangent line touching a reference point of the boundary curve and that is perpendicular to the vertical axis, wherein the reference point is an extremity of the boundary curve of the 3D virtual model along the vertical axis.
