Description
Technical Field
The invention relates to the technical field of oral repair, in particular to an open-faced preformed dental crown and a using method thereof.
Background
Dental diseases such as dental caries or pulpitis are common cases in oral diagnosis and treatment, filling treatment is generally adopted for dental caries treatment, materials such as resin or glass ions are mostly adopted for restoring the appearance of a tooth body, and the pulpitis needs to restore the appearance of the tooth body through filling treatment after root canal treatment. The affected teeth after the tooth treatment often have the defects of poor filling body fixing position, easy falling, increased tooth brittleness, easy fracture and the like, so the subsequent permanent repair treatment, namely a cast crown or a porcelain crown and the like, is needed. Similar tooth body treatment is similarly adopted for decayed teeth, pulpitis and the like of deciduous teeth of children, and because the deciduous teeth of the children fall off and are replaced during the 6-13 years old and the permanent repair process is complicated and expensive, the permanent repair is not carried out after the filling treatment is carried out on the deciduous teeth generally. However, a considerable part of treated deciduous teeth will remain in the mouth of the child for a long time, and transitional repair is still necessary to avoid the deciduous teeth filling body from falling off or the teeth from being fractured after treatment.
The existing restoration method of the deciduous teeth adopts a pre-crown forming technology, wherein the pre-crown forming technology refers to a preformed metal finished crown, the shape of the preformed metal finished crown simulates the appearance of the deciduous teeth, and the preformed metal finished crown is more attractive. The existing pre-crown forming technology is relatively complex to operate, and the filling body is required to be firstly carried out on the tooth to restore the tooth appearance, and then the pre-crown forming restoration can be carried out. The traditional pre-crown has the following disadvantages in clinical application: the formed occlusal surface is difficult to adjust and occlude, easy to wear through and long in adjusting and occluding time.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present invention, it should be understood that if there are terms such as "upper", "middle", "lower", "left", "right", etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the drawings, it is only for convenience of describing the present invention and simplifying the description, but not for indicating or implying that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, so that the terms describing the positional relationships in the drawings are only used for illustrative purposes and are not to be construed as limitations on the present patent, and specific meanings of the terms may be understood by those skilled in the art according to specific situations.
An embodiment is shown with reference to fig. 1 to 3.
An open-face preformed dental crown comprises a crown body 1 and a crown face 2 buckled on a tooth, wherein the crown body 1 and the crown face 2 are of an integrally formed structure and are formed by punching and molding 0.2mm stainless steel sheets by a continuous die, the crown face 2 is positioned at the upper end of the crown body 1, the crown face 2 is provided with an opening 3, the opening 3 is positioned in the center of the crown face 2, the opening 3 can complete the restoration process of an affected tooth in one step, namely, the affected tooth is directly tried on and bonded after a carious tissue is removed, then dental light-cured resin materials are filled in the opening 3 to form an occlusal surface, and then the occlusion is adjusted. Because the occlusion high point of the preformed occlusal surface of the pre-coronal pre-forming in the prior art is difficult to adjust, the early occlusion contact and the occlusion wound are easily caused, but the opening 3 of the invention has no occlusal surface and only needs to be filled with dental light-cured resin material to recover the occlusal surface, thereby avoiding the generation of the occlusion high point and the difficult occlusion adjustment.
The crown surface 2 is horizontally narrowed from outside to inside, which plays a role of holding the affected teeth, and the inverted support can also prevent the crown body 1 from sinking and causing periodontal injury. The invention does not imitate the occlusion shape of deciduous teeth, so the thickness of the crown body 1 is thinner, the neck edge 6 of the crown body 1 is narrowed and thinned, the appearance of the neck edge of the crown body 1 is convenient to adjust, and the size of the model of the invention can be selected to wear by measuring the size of the affected teeth.
Specifically, the crown body 1 is in the shape of a tooth with a convex middle part, the crown body 1 is hollow and is communicated with an opening 3, the crown body 1 is connected with the crown surface 2 through an arc 4, and the crown surface 2 is further provided with an inverted support 5. The number of the reverse buckles 5 is 2 to 4, and preferably the number of the reverse buckles 5 is 2. The inverted bracket 5 is buckled on the upper end surface of the tooth to prevent the crown body 1 from sinking and causing periodontal injury.
In particular, the crown body 1 covers the outside of the tooth. The neck edge 6 of the crown body 1 narrows from outside to inside and becomes thin. The inverted support (5) is attached to the occlusal surface of the teeth.
According to different sizes of teeth, the invention can be designed into different models to meet the requirements of different tooth sizes.
