Embodiment 1

[0070] This embodiment provides a new type of facebow, including a face mask frame 1. The face mask frame 1 is in the shape of a cross. Two brackets can be used to connect into a cross-shaped structure, or four brackets can be used to splice into a cross-shaped structure, or an integrated The formed cross-shaped structure can be a standard cross-shaped structure or a cross-shaped structure. This embodiment adopts an integrally formed cross-shaped structure, as shown in Figures 1 and 2. The four brackets of the cross-shaped face mask frame 1 correspond to the nose, chin, left face and right face of the patient's face respectively. At the corresponding position, it is enough to realize that the face mask frame 1 is similar to a mask to cover the facial area corresponding to the oral cavity. The face mask frame 1 is provided with a connector 2 for connecting the fork or the bracket, which is detachably connected, preferably the connector 2 is arranged at the center of the cross-s...

Embodiment 2

[0073] As a further improvement on the basis of Example 1, the groove 3 for accommodating the radio-resistant gutta-percha can be a continuous cross-shaped groove. In this embodiment, a plurality of mutually independent grooves are regularly distributed along the cross-shaped trend on the face mask frame 1 to form a cross, and the notch shape of each groove 3 is a polygonal structure; further preferably, the notch of the groove 3 The shapes include triangles and quadrilaterals, and the grooves 3 whose notch shape is triangular and the grooves 3 whose notch shape is quadrilateral are distributed alternately, as figure 1 shown.

Embodiment 3

[0075] Further improvement on the basis of Example 2, the outer surface of the face mask frame 1 is also provided with a plurality of protrusions 4, and all the protrusions are distributed along the cross-shaped array of the face mask frame 1, showing a city wall structure; and Each of the four supports of the face mask frame 1 is provided with two rows of protrusions 4, such as figure 2 mentioned.

Abstract

The invention discloses novel facebow and application thereof. The novel facebow comprises a cross-shaped face hood bracket, wherein a connecting piece used for being connected with a combined fork ora combined denture is arranged on the face hood bracket; and grooves used for accommodating a radio-resistant dental adhesive are formed in the outer surface of the face hood bracket and in the cross-shaped direction. According to the multifunctional digital facebow, three-dimensional information of the face and dentition of a patient is accurately and rapidly acquired, a virtual patient is constructed, and the relation of teeth, gum gingiva and lips of the patient are displayed in an omnibearing manner; meanwhile, virtual jaw relationship transfer is completed, and the important effect for guiding prosthesis manufacture and doctor-patient communication is achieved. The facebow is convenient to use and light, and discomfort of the patient is reduced; and besides, digital data obtained byfitting can be imported into design software of dental prosthetic restoration, the prosthesis is manufactured in a CAD / CAM manner, and a finished product is consistent with the design.

Description

technical field [0001] The invention relates to the technical field of oral restoration and implantation, in particular to a novel facebow and its application. Background technique [0002] In the clinical process of oral restoration and implantation, in order to make the restoration more accurate and effective, it is often necessary to transfer the positional relationship between the patient's upper and lower dentition and the temporomandibular joint to the jaw frame to simulate the patient's oral situation and guide the design of the restoration and making. [0003] The jaw frame can be divided into simple jaw frame, semi-adjustable jaw frame and fully adjustable jaw frame. Since the simple jaw frame can only simulate simple opening and closing movements, it is difficult to obtain good restoration results for complex patients. For the semi-adjustable jaw frame and the fully adjustable jaw frame, it is necessary to use the face bow to transfer the patient's maxillary denti...
