Description

Technical area

The present invention relates to a technology for dental restoration and more particularly to a dental device and a dental prosthesis comprising such a safety device.

background

Teeth are important organs for humans to chew food and absorb nutrients, and also to have a beautiful face and to support pronunciation. In practice, however, partial edentulousness or isolated edentulousness, which is caused by advancing age and different dental diseases, the physical health as well as the pronunciation ability of each patient and senior citizen strongly. For this reason, it is continuously being investigated how the missing teeth can be restored. In the case where the missing tooth has a good tooth, the usual restoration procedure is as follows: grinding and polishing the healthy teeth on the two sides of the section 400 with missing tooth by 50% to form a cone and use the cone as a base tooth; Making a corresponding denture body 200 and its securing device, wherein the securing device is a connecting part 300 for the missing tooth and a security part 500 that with the connecting part 300 connected to the missing tooth includes; and during the restoration treatment insertion of the denture body 200 and its securing device to the base 100 , 1 - 4 show the case where a tooth is missing. However, in cases where several teeth have been lost and some healthy teeth have remained, for example, when only 3-5 teeth are left in an old man, the conventional method has the following disadvantages. Since there are few base teeth, the base teeth should withstand very large forces, and if the tooth on one side of the base teeth is used for chewing food, the base tooth can move under the very large forces, so that the base tooth can be damaged. Therefore, there is a need to offer a solution for restoring teeth in such cases.

Summary of the invention

The present invention provides a dental device and a dental prosthesis which can solve at least part of the above problems.

According to one embodiment of the present invention, there is provided a dental securing device comprising: a connecting part, a securing part and an alveolar ridge fitting part, wherein the alveolar ridge fitting part fits to the alveolar ridge and is connected to the connecting part.

Alternatively, there are two alveolar ridge fittings, and they are located on two sides of the security part to be connected to the security part, respectively.

Alternatively, the alveolar crest fitting part has a saddle shape.

Alternatively, the alveolar crest fitting part has a multi-saddle shape.

Alternatively, the cut surface of the alveolar ridge fitting has an inverted "U" shape.

Alternatively, the connection part further comprises an extension part corresponding to the connection part.

According to another aspect of the present invention, there is provided a dental prosthesis comprising any one of the above-mentioned tooth securing devices and a dental prosthesis body, wherein the dental securing device is connected to the dental prosthesis body.

The dental safety device and the dental prosthesis according to the present invention have alveolar crest fittings. During dental restoration treatment, the alveolar crest fittings are connected to the upper crest of the dental beds to disperse the chewing force and avoid the left / right movement of the fitting parts. The present invention replaces the conventional active restorative body with a fixed restorative body, thereby improving the comfort of chewing food.

Short description of the embodiments

Hereinafter, the embodiments of this invention will be described in detail with reference to the accompanying drawings.

For a simple understanding show 5 and 6 a diagram of a dental prosthesis, comprising the inventive dental safety device.

The present disclosure discloses a dental securing device that includes a connector 300 , a security part 500 and an alveolar ridge fitting 700 past the alveolar ridge and with the connecting part 300 is connected.

It should be noted that the word "pass" herein may include a partial fit.

The present invention will be described below with reference to various embodiments.

Embodiment 1

Assuming that a patient has three front teeth, in this case, the dental securing device comprises a connecting part, a securing part and an alveolar crest fitting part, which fits on the alveolar crest and is connected to the connecting part. There are two alveolar ridge fittings and they are located on two sides of the security part to be connected to the security part respectively. In the dental restoration treatment, a base tooth made using a conventional method can be used to interact with the dental prosthesis according to the present invention. The denture can be used on the base tooth and a dental bed. During the dental restoration treatment, the alveolar crest fittings are connected to the upper crest of the beds to disperse the chewing force and avoid the left / right movement of the fittings. Therefore, the base tooth can be protected from damage. It should be noted that the three front teeth may be adjacent teeth or three teeth that are not adjacent to each other. In another embodiment, more healthy teeth, about 4-8 teeth, may be present. In other embodiments, the healthy teeth may be in a different portion of the mouth. It should be noted that these examples are not intended to limit the present invention. Other examples that are within the scope of the present invention will not be described further.

The alveolar crest fitting may have a saddle shape, and the saddle shape conforms to the shape of the dental beds for better securement. If more denture body is required, the alveolar crest fitting may have a multi-saddle shape.

In one embodiment, the intersection of the alveolar crest fitting may have an inverted "U" shape (in 7 shown). The two sides of the inverted "U" shape run down to facilitate insertion of the denture, and the two sides of the inverted "U" shape snap in with the dental beds. At the beginning of a restoration treatment, the two sides of the inverted "U" shape are connected to the dental beds.

For better security, the connecting part also includes an extension part 600 which contacts the dental beds corresponding to the connecting part. The dental beds corresponding to the connecting part mentioned herein designate dental beds which are connected in use to the connecting part. The extension part is connected to the dental beds, whereby a part of the chewing force is distributed.

The present invention also includes a dental prosthesis comprising the above-mentioned dental safety device and a dental prosthesis body, wherein the dental safety device is connected to the dental prosthesis body.

Note that the sectional view is a sectional view in the situation of 5 and along the line is AA. The front teeth can be understood as incisors and lateral incisors.

The dental safety device and the dental prosthesis according to the present invention have alveolar crest fittings. During dental restoration treatment, the alveolar crest fittings are connected to the upper crest of the dental beds to disperse the chewing force and avoid the left / right movement of the fitting parts. The present invention replaces the conventional active restorative body with a fixed restorative body, thereby improving the comfort of chewing food. In order to reduce the cost and still ensure the function of the dental prosthesis, the dental securing device is cast using teeth-specific alloy, alloy and precious metal intended for teeth, and dielectric ceramic powders, or the dental securing device will be toothed using one Cast alloy and dielectric ceramic powders, or the dental device is cast using a precious metal and ceramic dielectric powders. The process of casting the dental device using an alloy (eg, titanium alloy) intended for teeth and alloy or precious metal intended for teeth, and dielectric ceramic powders is well known to those skilled in the art and thus will not be described any more.

It should be noted that the above embodiments are only examples of the present invention and are not intended to limit the present invention, and that those skilled in the art could devise alternative embodiments within the scope defined in the claims. In the claims, any reference numerals in parentheses do not limit the claims. The words "comprising" do not exclude the possible elements and steps not shown in the claims. The words "a", "an", "an" do not exclude multiple elements. The words first, second, third etc. do not restrict the order, but are merely used to make an element visible.
