Short description of the embodiments

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

The present disclosure discloses a dental securing device that includes a connector 300 for a missing tooth and two security parts 500 includes. The security part 500 includes a toothpaste part 700 which fits the adjacent teeth and a tooth gap snap-in part 800 that snaps into the tooth gap. An end of the tooth fitting 700 is with the tooth gap snap-in part 800 connected, and the other end is connected to the connecting part 300 connected to the missing tooth. It should be noted that the adjacent teeth may be the teeth adjacent to the missing tooth portion (eg, the first adjacent tooth and the second adjacent tooth in the embodiment) or the teeth (eg, the third adjacent tooth or the fourth adjacent tooth ) may be adjacent to the teeth adjacent to the missing tooth portion or may include both types of teeth (eg, including the first adjacent tooth and the third adjacent tooth, or including the second adjacent tooth and the fourth adjacent tooth). Of course, variants can also be included. For example, in one embodiment, three teeth may be near the missing tooth portion. The tooth gap mentioned above is the natural tooth gap. In the event that there is no natural tooth space or the natural tooth space is too narrow to fit the gullet snap-in portion, the edge of the adjacent tooth may be slightly abraded to form a gap. Such minor abrasion does not severely damage the healthy tooth, so it is not painful to the patient. The above-mentioned fitting operation may be a partial fitting, and the snapping operation may be a partial snapping or clamping.

In one embodiment, for ease of description, two securing parts may comprise a first securing part and a second securing part. As in 8th is shown, the adjacent teeth can have a first adjacent tooth 701 , a second neighbor tooth 702 , a third neighbor tooth 703 , a fourth neighbor tooth 704 , a fifth neighbor tooth 705 and a sixth neighbor tooth 706 include. If other neighboring teeth are present, these teeth can be arranged according to this rule. The tooth gap may be a first tooth gap 801 , a second tooth gap 802 , a third tooth gap 803 and a fourth tooth gap 804 include. If other tooth spaces are present, these gaps can be arranged according to this rule. The toothpaste part 700 may include a first toothpaste part, a second toothpaste part, a third toothpaste part, a first and third toothpaste part, a second and fourth toothpaste part, etc. Since the shapes and configurations of these adjacent teeth, gullets and tooth parts are similar to those described in this embodiment, no further description will be provided.

In order that the dental prosthesis body is reliably secured, the shape of the sectional surface of one end of the gullet snap part that is far away from the toothpaste part is a curve shape. The curved part 8100 may contact the surface of the tooth to distribute a portion of the force applied to the denture body to a healthy tooth.

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 for casting the dental device using an alloy (eg, titanium alloy) for teeth and alloys or precious metals intended for teeth and dielectric ceramic powders is well known to those skilled in the art and thus will not be described any more.
