Embodiment 1

[0039] The present invention provides a kind of Maryland bridge body manufacturing method, please refer to figure 1 , figure 1 Shown is the flow chart of the preferred embodiment of Maryland bridge body manufacturing method of the present invention, and described method comprises the following steps:

[0040] S100. Acquire three-dimensional data in the patient's mouth, the three-dimensional data in the patient's mouth includes three-dimensional data of missing teeth and three-dimensional data of natural teeth located on both sides of the missing teeth. The missing tooth is the gap left by the loss of natural teeth, which is called missing position in the denture restoration industry, that is, the space left after the loss of natural teeth, the three-dimensional data of natural teeth located on both sides of the missing teeth refers to the The three-dimensional data of the two natural teeth adjacent to the missing tooth; in actual use, the three-dimensional data in the patient...

Embodiment 2

[0054] The present invention also provides a Maryland bridge, please refer to figure 2 and image 3 , figure 2 A structural representation of a Maryland bridge body provided by the present invention; image 3 It is a schematic diagram of the use state of a Maryland bridge body provided by the present invention. The Maryland pontic comprises: abutment base 100, wing edge 200 and foundation pile 300; specifically, the abutment base 100 is used to be set in missing teeth; the wing edge 200 is connected to both sides of the abutment base 100, and The abutment base 100 forms a bridge-like structure, and the wing 200 is provided with fitting grooves 210. The fitting grooves 210 match the surfaces of the natural teeth facing the inside of the oral cavity on both sides of the missing tooth, and can be used in actual use. Adhesive is set in the fitting groove to keep the connection with the natural tooth, and the foundation pile 300 is arranged on the top of the abutment base 100 ...

Embodiment 3

[0063] The present invention also provides a prosthetic tooth, including a crown 400 , which also includes the above-mentioned Maryland pontic, wherein the crown is arranged on the foundation pile 300 .

[0064] In the embodiment of the present invention, please refer to Figure 4 , Figure 4 It is a structural schematic diagram of a prosthetic denture provided by the present invention. When the three-dimensional data in the patient's mouth is obtained, a plaster model that restores the internal situation of the oral cavity will also be produced based on the three-dimensional data, and the completed Maryland bridge will be worn on the position of the missing tooth of the plaster model to form a whole for subsequent use. The instrument scans the whole body to obtain the restored 3D data, which is imported into the computer to form a 3D model, and the crown is designed on the foundation pile 300 of the Maryland Bridge in the 3D model, and the 3D model of the crown can be obtain...

Abstract

The invention discloses a Maryland bridge body manufacturing method, a Maryland bridge body and a repaired false tooth. The method comprises the following steps: acquiring intraoral three-dimensional data of a patient, wherein the intraoral three-dimensional data of the patient comprise three-dimensional data of a missing tooth and three-dimensional data of natural teeth located at the two sides of the missing tooth; generating three-dimensional data of the Maryland bridge body according to the three-dimensional data of a position of the missing tooth and the three-dimensional data of the natural teeth located at the two sides of the missing tooth; and printing the Maryland bridge body according to the three-dimensional data of the Maryland bridge body. According to the Maryland bridge body manufacturing method, the Maryland bridge body and the repaired false tooth, through acquiring the intraoral three-dimensional data of the patient, generating the three-dimensional data of the Maryland bridge body according to the three-dimensional data of the position of the missing tooth and the three-dimensional data of the natural teeth located at the two sides of the missing tooth, and printing the Maryland bridge body according to the three-dimensional data of the Maryland bridge body, the Maryland bridge body can be accurately attached to inner sides of the natural teeth with destroying the natural teeth, and completeness of the natural teeth is guaranteed.

Description

technical field [0001] The invention relates to the technical field of oral prosthesis production, in particular to a manufacturing method of a Maryland pontic, a Maryland pontic and a prosthetic denture. Background technique [0002] Dentures, also known as prosthetic dentures, are called "Maryland pontics". They are a type of dentures and are mostly used to repair a single missing tooth. After the natural tooth is missing, there will be a gap left, which is called missing position in the industry. There is no support at the bottom of the missing position. When doing this kind of restoration, many choose implant restoration, but implant surgery has certain medical risks, and patients may not be able to accept it. Therefore, In the prior art, a Maryland pontic is installed in the missing position, and the denture can be repaired without surgery. This Maryland pontic needs to be overlapped on two adjacent natural teeth to make the pontic stable in the missing position. Howev...
