Embodiments provide a method and a device for processing a three-dimensional oral cavity model. The disclosed method for processing a three-dimensional oral cavity model comprises the operations of: acquiring scan data obtained by scanning a target object; generating a border of a base on the basis of the scan data; acquiring a gingival area from the scan data; and generating and connecting a mesh between the gingival area and the border of the base, and generating a mesh different from the mesh at a position corresponding to the palate so as to obtain teeth model data. Des modes de réalisation concernent un procédé et un dispositif de traitement d'un modèle tridimensionnel de cavité buccale. Le procédé de traitement d'un modèle de cavité buccale tridimensionnelle divulgué comprend les opérations consistant à : acquérir des données de balayage obtenues par balayage d'un objet cible ; générer une limite d'une base sur la base des données de balayage ; acquérir une zone gingivale à partir des données de balayage ; générer et connecter un maillage entre la zone gingivale et la bordure de la base et générer un maillage différent du maillage à une position correspondant au palais de façon à obtenir des données de modèle de dents. 실시예들에 따라 삼차원 구강 모델 처리 방법 및 장치가 개시된다. 개시된 삼차원 구강 모델을 처리하는 방법은, 대상체를 스캔함으로써 얻어진 스캔 데이터를 획득하는 동작,상기 스캔 데이터를 기반으로 베이스의 테두리를 생성하는 동작,상기 스캔 데이터로부터 치은 영역을 획득하는 동작, 상기 치은 영역과 상기 베이스의 테두리 사이에 메쉬를 생성하여 연결하되, 입천장에 대응하는 위치에 상기 메쉬와 다른 메쉬를 생성함으로써 치아 모형 데이터를 획득하는 동작을 포함한다.
