Abstract
In a measuring technique used to restore a tooth with an employment of an implant structure, it is desirable to precisely determine the direction and position of bonding points in which a prosthesis is attached to the implant structure at the time of curing the tooth by of the implant structure. Upon precisely measuring the direction and position of bonding points in which a prosthesis is attached to the implant structure, measurement points are provided with the bonding points, and are taken a picture by a camera. In the picture thus taken, shape and position of the measurement points are measured by an image processor device by way of illustration so as to measure the positional relationship of the bonding points of the implant structure which is embedded in a human jaw.
Claims16
A measuring device comprising:
- implant structures adapted to be embedded into a patient's law, wherein said implant structures comprise bonding portions for securing a prosthesis to the implant structures;
- measuring objects provided on said bonding portions, respectively;
- a camera device which concurrently photographs specified shapes of said measuring objects;
- and a control device comprising:
- a read-out device which reads the specified shapes and a positional relationship of the measuring objects photographed by the camera device;
- and
- a calculator device which calculates a direction of each of the measuring objects based on the specified shapes read by the read-out device and which measures a positional relationship of the bonding portions based on the positional relationship of the measuring objects read by the read-out device.
A method of measuring a direction and positional relationship of bonding portions provided on implant structures, said method comprising the steps of:
- concurrently photographing specified shapes of measuring objects, provided on respective bonding portions of corresponding implant structures embedded in a human jaw, by means of a camera device;
- measuring the specified shapes and positional relationship of the measuring objects photographed by the camera device so as to determine the direction of each of the bonding portions based on the shapes of the measuring objects photographed by the camera device;
- and
- determining the positional relationship of the bonding portions based on the positional relationship of the measuring objects photographed by the camera device.
