Description

Tooth removal guide, tooth removal device and dental prosthesis

The present invention relates to a tooth deletion guide device used to delete a tooth, and in particular, a tooth deletion guide device capable of deleting a tooth more precisely with less tooth removal amount than before, a tooth deletion device including the same, and a dental prosthesis suitable thereto It is about.

In general, in order to repair a lost tooth, it is common to remove a tooth used as a preparation tooth and attach a crown to the tooth preparation deleted by a metal material or a ceramic material and connect and fix it with an artificial tooth.

A typical example of such a conventional prosthesis is a crown bridge. If the nerve of the tooth used as abutment is alive, most of the tooth is removed under anesthesia. At this time, a temporary tooth is worn to protect the dimension of the deleted tooth (the nerve of the tooth) and prevent the tooth from moving until the final prosthesis is removed. Even if the crown is removed to prevent the tooth from moving, and if the pulp is alive, a temporary tooth is provided to protect the pulp. In the case of deleting a part of the tooth in order to prosthetic aesthetic prosthesis, the restoration is temporarily performed on the deleted area.

In the case of the tooth removal for the conventional crown, crown bridge, laminate, splint, etc., the quality of the deletion was inevitably caused by the skill of the operator. And the type and extent of deletion required by the prosthesis could not be accurately determined. In some cases, too many hemorrhoids may be removed, resulting in neurotherapy or hypersensitivity after the final prosthesis restoration. However, minimally deleted prostheses can be free in many ways. In the present invention, in most cases, the enamel of the tooth is mostly preserved, so it is not necessary to repair the temporary tooth. In addition, the pain suffered by the patient is relatively reduced, and in most cases, it can be deleted without anesthesia. In addition, the medical time is also much reduced.

In this regard, the inventors of the present invention through the Republic of Korea Patent Publication 2012-0053457 (name of the invention: tooth deletion guide device), the induction device support that is fixed to the teeth in the form of covering the part or all of the teeth, gums or alveolar bone, and teeth Tooth removal guide device including a tooth removal guide for guiding a cutting machine for deletion has been developed.
