Abstract
It is provided an equipment for treatment of a person, wherein the equipment is configured to achieve a target denture geometry characterized by a target denture plane (3), the target denture plane lying parallel to an internal ear line (11) through a left internal ear point (7) and a right internal ear point (9) of the person. Further, a manufacturing method is provided.
Claims18
A method, the method comprising:
- measuring a left internal ear point of a person, wherein the left internal ear point is a location beyond a left eardrum of a left ear towards the interior of the left ear;
- measuring a right internal ear point of the person, wherein the right internal ear point is a location beyond a right eardrum of a right ear towards the interior of the right ear;
- defining an internal ear line through the left internal ear point and the right internal ear point;
- defining a chewing base plane for the person, the chewing base plane lying parallel to the internal ear line;
- and
- defining an auxiliary plane based on one or more of
- (i) a left triangle plane of a left triangle defined by the left internal ear point, the right internal ear point, and a left eye point of a left eye, and
- (ii) a right triangle plane of a right triangle defined by the left internal ear point, the right internal ear point, and a right eye point of a right eye,
- wherein the internal ear line lies within the auxiliary plane, and
- wherein the auxiliary plane is rotated around a rear rotation axis being parallel to the internal ear line about an angle between 11° and 17° downwards to obtain the chewing base plane,
- wherein the rear rotation axis is obtained by:
- constructing a connecting line intersecting the internal ear line in a middle between the left internal ear point and the right internal ear point and intersecting an eye line in the middle between the left eye point and the right eye point;
- obtaining a connection length of the connecting line between the internal ear line and the eye line;
- and
- extending the connecting line in a rear direction by between 1.7 and 2.3 times the connection length, wherein an end of the extended connecting line defines a position of the rear rotation axis;
- generating data defining the chewing base plane to characterize a configuration of an equipment for the treatment of the person, such that applying the equipment to the person achieves a target denture geometry characterized by the chewing base plane;
- supplying said data defining the chewing base plane to a manufacturing system;
- and
- manufacturing the equipment for the treatment of the person based on said data defining the chewing base plane using the manufacturing system, wherein applying the equipment to the person achieves the target denture geometry.
