A tooth moving method using a three-dimensional printer according to the present invention comprises the steps of: scanning a patients oral cavity using an oral scanner a dental terminal performing an orthodontic treatment by using the scanned oral-cavity data a server transmitting, to a three-dimensional printer, orthodontic data relating to the patients tooth or teeth that underwent the orthodontic treatment, and the three-dimensional printer generating and outputting an orthodontic model generating transparent orthodontic braces by vacuum pressing a transparent synthetic resin plate into the orthodontic model by means of a vacuum mould coating transparent silicone onto areas where the transparent orthodontic braces make contact with the gums and teeth a coating device receiving from the server, via a communication unit, information about the age, gum state or bad teeth of the patient the coating device coating Hexamedine Solution onto the transparent orthodontic braces if the patient has gum disease the coating device coating a fluorine solution onto the transparent orthodontic braces if the patient has a bad tooth. Embodiments of the present invention may provide a tooth moving system and method using a three-dimensional printer whereby bad teeth are prevented by covering the inside of a synthetic plate with fluorine, and gum inflammation is prevented by covering the inside of the synthetic plate with Hexamedine.Selon linvention, un procédé de déplacement de dent faisant appel à une imprimante tridimensionnelle comprend les étapes suivantes consistant à : balayer la cavité buccale dun patient à laide dun dispositif de balayage par voie orale effectuer, par un terminal dentaire, un traitement orthodontique à laide des données de cavité buccale balayée transmettre, par lintermédiaire dun serveur, à une imprimante tridimensionnelle, des données orthodontiques concernant la dent ou les dents du patient qui a subi le traitement orthodontique, et générer et délivrer
