[0047] A dental system 100 with a baseline so that a digital three-dimensional teeth model can be combined with an anatomical location and a plane analysis of the human body, as illustrated in FIGS. 2 to 12, includes an acquisition unit 110, an analysis unit 120, and a control unit 130.

[0048] The acquisition unit 110 is formed to be held by an anodontia patient or a partial anodontia patient in a mouth to acquire a tooth height or tooth distance of the anodontia patient or the partial anodontia patient.

[0049] The acquisition unit 110 acquires data acquired by a facial scanner, three-dimensional data acquired by a dental CT, and digital three-dimensional data acquired by scanning teeth of a plaster model, respectively.

[0050] The acquisition unit 110 is combined with an anatomically ideal location by the control unit 130 when moving to the anatomically ideal location together with the analysis unit 120 to be described below.

[0051] The acquisition unit 110 is configured by a base surface 111, a connection surface 112, a holding surface 113, and a scan protrusion surface 114.

[0052] The base surface 111 becomes a reference by crossing vertical and horizontal lines or surfaces.

[0053] In detail, the base surface 111 is formed in a vertical and horizontal shape, that is, a cross shape and provided at a constant interval with the holding surface 113 to be held by the anodontia patient in the mouth.

[0054] The base surface 111 always becomes a reference in an anatomically ideal location so that the acquisition unit 110 including the connection surface 112, the holding surface 113 and the scan protrusion surface 114 may be rapidly placed at an accurate location even if the acquisition unit 110 is moved to another location.

[0055] In the related art, there is a disadvantage that it takes a lot of time and the work is inconvenient when the acquisition unit 110 is placed at the anatomically ideal location without a separate reference when acquiring the tooth height or the tooth distance of the anodontia patient or the partial anodontia patient.

[0056] The acquisition unit 110 is combined with the analysis unit 120 to be described below through the base surface 111 of the acquisition unit 110 and a base surface 121 of the analysis unit 120 so as not to be misaligned with each other.

[0057] In the present disclosure, it is exemplified that the base surface 111 is formed in a cross shape to be a reference so that the acquisition unit 110 including the base surface 111 is rapidly placed at the accurate location, but the base surface 111 may be modified to other shapes as long as being a reference so that the acquisition unit 110 including the base surface 111 is rapidly placed at the accurate location.

[0058] The connection surface 112 is connected with a cross center of the base surface 111 in a bar shape.

[0059] In detail, the connection surface 112 is formed in a quadrangular bar shape so that one end is connected with a cross center of the base surface 111.

[0060] The connection surface 112 is formed in the quadrangular bar shape, but may be modified in other shapes such as a cylindrical shape so long as the connection surface 112 may maintain a distance between the base surface 111 and the holding surface 113.

[0061] The connection surface 112 maintains the distance between the base surface 111 and the holding surface 113 and is formed to be longitudinally adjusted in multi stages and the like according to the anodontia patient or the partial anodontia patient to adjust the distance between the base surface 111 and the holding surface 113.

[0062] The holding surface 113 has a hemispherical shape and is connected to one end corresponding to the one end of the connection surface 112 connected with the base surface 111 so as to be held by a maxillary gum and a mandibular gum of the anodontia patient or the remaining maxillary teeth and the remaining mandibular teeth of the partial anodontia patient in the mouth.

[0063] The holding surface 113 has a hemispherical shape, in which a round portion of the hemispherical shape is located at a lip portion of the anodontia patient or the partial anodontia patient and a straight portion thereof is located inside the mouth of the patient.

[0064] Grooves are formed on upper and lower surfaces of the holding surface 113, respectively, and when the patient holds the holding surface 113, a filling material such as silicone harmless to the human body is introduced into the groove.

[0065] A plurality of scan protrusion surfaces 114 is formed to protrude from the holding surface 113.

[0066] Specifically, the plurality of scan protrusion surfaces 114 is formed to protrude from the hemispherical holding surface 113, that is, an outer circumference of the round portion or formed to protrude in a direction of the base surface 111.

[0067] Among the scan protrusion surfaces 114, one end of the scan protrusion surface formed to protrude in the direction of the base surface 111 is exposed out of the patient's mouth to be accurately scanned.

[0068] The scan protrusion surface 114 is formed in a cylindrical shape or a square pillar shape, and a plurality of hemispherical protrusions 114a is formed on an outer circumference of the cylindrical shape or the square pillar shape.

[0069] In the related art, when scanned using a scanner, that is, an oral scanner, the scan protrusion surface cannot be accurately scanned due to a planar shape.

[0070] Accordingly, in the present disclosure, the hemispherical protrusion 114a is formed on the outer circumference of the scan protrusion surface 114 so as to be accurately scanned.

[0071] In the present disclosure, it is exemplified that the scan protrusion surfaces 114 are arranged in different shapes from each other such as the cylindrical shape and the square pillar shape, but in some cases, the scan protrusion surfaces 114 may be arranged in only the cylindrical shape or only the square pillar shape, that is, only the same shape.

[0072] A vertical protrusion surface 115 is included in the acquisition unit 110 and formed vertically in front of the upper surface of the holding surface 113 to be held by the maxillary gum of the anodontia patient so as to be fitted to a facial center line of the anodontia patient.

[0073] The vertical protrusion surface 115 is included in the acquisition unit 110 and formed vertically in front of the upper surface of the holding surface 113 to be held by the maxillary gum of the anodontia patient or the remaining maxillary teeth of the partial anodontia patient so as to be fitted to a facial center line of the anodontia patient.

[0074] The vertical protrusion surface 115 is formed on the upper surface of the holding surface 113 in a cylindrical shape to be in contact with a portion where the maxillary gum is first contacted.

[0075] The vertical protrusion surface 115 is formed on the upper surface of the holding surface 113 to fit a center line of the patient's face, and in some cases, may be formed even on a lower surface of the holding surface 113.

[0076] When the acquisition unit 110 is held by the anodontia patient or the partial anodontia patient, a filling material such as silicone harmless to the human body is filled in an empty space between the acquisition unit 110 and the gums of the anodontia patient or the remaining teeth of the partial anodontia patient.

[0077] Since the filling material is filled in the empty space between the acquisition unit 110 and the gums of the anodontia patient or the remaining teeth of the partial anodontia patient, the acquisition unit 110 is not moved to acquire accurately the tooth height, the tooth distance, or the like of the patient.

[0078] The acquisition unit 110 is fabricated to have a different height by measuring an average height due to a different unique height for each patient.

[0079] The analysis unit 120 is disposed at a maxillary landmark or a mandibular landmark of the anodontia patient or the partial anodontia patient to analyze an occlusal plane of the anodontia patient or the partial anodontia patient.

[0080] The analysis unit 120 consists of a base surface 121, a center surface 122, and an occlusal surface 123.

[0081] The base surface 121 becomes a reference by crossing vertical and horizontal lines or surfaces.

[0082] In detail, the base surface 121 is formed in a vertical and horizontal shape, that is, a cross shape and always becomes a reference in an anatomically ideal location so that the analysis unit 120 including the center surface 122 and the occlusal surface 123 may be rapidly placed at an accurate location even if the analysis unit 120 is moved to another location.

[0083] In the present disclosure, it is exemplified that the base surface 121 is formed in a cross shape to be a reference so that the analysis unit 120 including the base surface 121 is rapidly placed at the accurate location, but the base surface 121 may be modified to other shapes as long as being a reference so that the analysis unit 120 including the base surface 121 is rapidly placed at the accurate location.

[0084] The base surface 121 includes a form capable of analyzing a landmark in the mouth of the patient, and a form capable of analyzing an occlusal plane and a horizontal line connecting a vertical center line of the face and pupils of eyes out of the mouth of the facial skin or skull, and the mandible of the human body.

[0085] The center surface 122 is connected with the base surface 121 so that one surface is disposed at an arch center which is a landmark of the anodontia patient or the partial anodontia patient.

[0086] The center surface 122 is elongated in a longitudinal direction and one end of the center surface 122 is disposed at a maxillary or mandibular arch center (middle line) which is a landmark of the anodontia patient or the partial anodontia patient.

[0087] The occlusal surface 123 is connected with the center surface 122, in which the occlusal surfaces 123 are disposed at both sides based on the center surface 122 to be connected to each other, and the occlusal surface 123 is disposed on an occlusal plane of the anodontia patient or the partial anodontia patient.

[0088] The occlusal surface 123 is elongated in a longitudinal direction and one end and the other end thereof are formed to be curved orthogonally in an upper direction.

[0089] The center of the occlusal surface 123 of which one end and the other end are formed to be curved orthogonally in the upper direction is connected with the center surface 122, and one end and the other end formed to be curved orthogonally in the upper direction are connected with the center surface 122 in parallel with each other.

[0090] Referring to FIG. 7, when viewed from the side surface of the anodontia patient, the occlusal surface 123 refers to an anatomical base in which a connection line of maxillary and mandibular teeth coincides with or is 15° inclined with a connection line of the ear and the nose (CAMPER'S PLANE) or the ear and the eye bag (FRANKFURT PLANE).

[0091] That is, the occlusal plane of the anodontia patient is configured at the same angle and the same form as an anatomical component that can be easily analyzed.

[0092] The acquisition unit 110 and the analysis unit 120 are combined with each other around the base surface 111 of the acquisition unit 110 and the base surface 121 of the analysis unit 120.

[0093] When the acquisition unit 110 is first placed at an anatomically ideal location of the anodontia patient, the analysis unit 120 is integrally combined with the acquisition unit 110 through the base surface 121.

[0094] The digital three-dimensional teeth model of the anodontia patient or the partial anodontia patient is fabricated in advance and consists of maxillary teeth and mandibular teeth and consists of a maxillary teeth and gum unit and a mandibular teeth and gum unit to be controlled to each other through the base surface 121 of the analysis unit 120, and has a form of a female pattern and a male pattern so that a base portion of the maxillary teeth and the mandibular teeth and the upper surface portion of the gum may be coupled to each other.

[0095] The teeth model of the anodontia patient or the partial anodontia patient is classified according to a form and a size of the arch and a dental shape, and a plurality of arch forms and dental shapes are output when the teeth model is output as an image.

[0096] The analysis unit 120 is fabricated to have different occlusal planes by measuring an average occlusal plane by varying a unique occlusal plane for each anodontia patient.

[0097] The control unit 130 is connected to the acquisition unit 110 and the analysis unit 120, respectively to control the acquisition unit 110 and the analysis unit 120 to be modularized simultaneously or selectively.

[0098] The control unit 130 controls the modularization temporarily to adjust the movement due to an unexpected event in the process of moving the acquisition unit 110 and the analysis unit 120 to an anatomically ideal location.

[0099] Hereinabove, the present disclosure has been described with reference to preferred exemplary embodiments, but the technical idea of the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that modifications or changes can be made within the appended claims, and these modifications or changes will belong to the appended claims.
