Abstract
(EN)
Provided is an implant surgery guiding method capable of guiding placement position, direction and depth of a fixture, and the like to an operator by using an image during implant surgery. The guiding method comprises the steps of: (a) generating a three-dimensional oral cavity image of a patient; (b) designing a target arrangement state including a target position and a target direction of the implant fixture on the basis of the three-dimensional intraoral image; (c) attaching an oral cavity marker including a first pattern to the jawbone of the patient or the body around the same, determining a spatial relationship between the dental marker and the jawbone, attaching a handpiece marker including a second pattern to a handpiece of a dentist, and determining a spatial relationship between the handpiece marker and a handpiece; and (d) tracking the movement of the dental marker and the handpiece marker, estimating the positions and directions of the jawbone and the handpiece on the basis of change in positions and directions of the dental marker and the handpiece marker, and displaying, on a screen, a jawbone image portion and a handpiece image portion in which real-time change in position/direction of the jawbone and the handpiece are reflected.

L'invention concerne un procédé de guidage de chirurgie d'implant apte à guider la position, la direction et la profondeur de placement d'un dispositif de fixation, et analogues, à un opérateur à l'aide d'une image pendant une chirurgie d'implant. Le procédé de guidage comporte les étapes consistant : (a) à générer une image de cavité buccale tridimensionnelle d'un patient ; (b) à concevoir un état d'agencement cible comprenant une position cible et une direction cible du dispositif de fixation d'implant sur la base de l'image intrabuccale tridimensionnelle ; (c) à fixer un marqueur de cavité buccale comprenant un premier motif à l'os de la mâchoire du patient ou au corps autour de ce dernier, à déterminer une relation spatiale entre le marqueur dentaire et l'os de la mâchoire, à fixer un marqueur de pièce à main comprenant un second motif à une pièce à main d'un dentiste, et à déterminer une relation spatiale entre le marqueur de pièce à main et une pièce à main ; et (d) à suivre le mouvement du marqueur dentaire et du marqueur de pièce à main, à estimer les positions et les directions de l'os de la mâchoire et de la pièce à main sur la base d'un changement des positions et des directions du marqueur dentaire et du marqueur de pièce à main, et à afficher, sur un écran, une partie d'image d'os de la mâchoire et une partie d'image de pièce à main reflétant un changement en temps réel de la position/direction de l'os de la mâchoire et de la pièce à main.
