Title
(EN) ADAPTIVE ORTHODONTIC TREATMENT
(FR) TRAITEMENT ORTHODONTIQUE ADAPTATIF
Abstract
(EN) A processing device receives image data of an actual condition of a patient's dental arch at an intermediate stage of a multistage orthodontic treatment plan. The processing device compares the image data of the actual condition of the patient's dental arch to a planned condition of the patient's dental arch for the intermediate stage. The processing device identifies one or more clinical signs that the actual condition of the patient's dental arch has a deviation from the planned condition of the patient's dental arch for the intermediate stage of the multi-stage orthodontic treatment plan based on a result of the comparing. The processing device determines one or more probable root causes for the deviation based on the one or more clinical signs. The processing device additionally determines one or more corrective actions for the multi-stage orthodontic treatment plan based on the one or more probable root causes.
(FR) L'invention concerne un dispositif de traitement qui reçoit des données d'image d'un état réel de l'arcade dentaire d'un patient à une étape intermédiaire d'un plan de traitement orthodontique à plusieurs étapes. Le dispositif de traitement compare les données d'image de l'état réel de l'arcade dentaire du patient à un état désiré de l'arcade dentaire du patient pour l'étape intermédiaire. Le dispositif de traitement identifie un ou plusieurs signes cliniques indiquant que l'état réel de l'arcade dentaire du patient s'écarte de l'état désiré de l'arcade dentaire du patient pour l'étape intermédiaire du plan de traitement orthodontique à plusieurs étapes sur la base d'un résultat de la comparaison. Le dispositif de traitement détermine une ou plusieurs causes profondes probables de l'écart sur la base du ou des signes cliniques. Le dispositif de traitement détermine en outre une ou plusieurs actions correctives du plan de traitement orthodontique à plusieurs étapes sur la base de la ou des causes profondes probables.
