Embodiment Construction

[0022] Such as Figure 1-Figure 4 Shown is the movable bridge type dental post of the present invention, which is used to indirectly fix the denture crown (not shown) on the tooth bed 9 with the missing tooth 7 to be restored, and the missing tooth 7 to be restored has the residual root 5; The invented movable bridge type dental post for the denture includes the post base 1, the fixed pin 2, the movable pin 3, among which:

[0023] The size of the dental post base 1 is adapted to the inner cavity of the denture crown for assembly in the denture crown, the post base 1 serves as the core of the denture crown, so that the denture crown is stably sleeved on the outer surface of the dental post base 1;

[0024] Pile base 1 is a bridge body with a bridge structure, and the piers at the bottom of both sides of the bridge are fixed pins 2 and movable pins 3; specifically, fixed pins 2 are vertically arranged on the bottom side of the dental pile base 1. The other side of the base 1 relati...

Abstract

The invention discloses a movable bridge type tooth pile for a false tooth, which comprises a tooth pile matrix, a fixed pin and a movable pin. The size of the tooth pile matrix is adaptive to an inner cavity of a false tooth crown for being assembled in the false tooth crown; the fixed pin is vertically arranged at one side of the bottom of the tooth pile matrix; a pin hole vertically running through the tooth pile matrix is formed in the other side of the tooth pile matrix, which is opposite to the fixed pin; the pin hole is used for inserting the movable pin and the movable pin is longer than the pin hole; a tooth residual root is provided with a first positioning hole and a second positioning hole in advance; the fixed pin is connected with the first positioning hole by a safety pin from one side of the bottom of the tooth pile matrix; the movable pin then is inserted into the pin hole from the top of the tooth pile matrix, until the bottom end of the movable pin penetrates through the pin hole and is connected with the second positioning hole by a safety pin. According to the movable bridge type tooth pile for the false tooth, which is disclosed by the invention, independent mounting of the false tooth crown in a to-be-repaired tooth missing position can be implemented, so that full-crown repair carried out after part of tooth body tissues of healthy teeth at both sides of a missed tooth are abraded is avoided; moreover, the safety pins at both ends are assembled with a core, so that stability of a false tooth mounting structure can be kept; under the assisting action of an adhesive, the structure can be more stable.

Description

Technical field [0001] The invention relates to a denture fixing device for human oral restoration, in particular to a denture movable bridge type dental post. Background technique [0002] Dentures are commonly referred to as "false teeth", and dentures mean teeth that perform "duty" for humans. Medically, it is a general term for restorations made after partial or all of the upper and lower teeth are missing. Dentures are divided into fixed dentures and movable dentures. The fixed dentures are supported by healthy teeth on both sides of the missing teeth to fix the dentures in the oral cavity. It is suitable for a small number of missing teeth, intermittent missing teeth, and the remaining teeth are in good health. During the restoration, the healthy teeth on both sides of the missing tooth should be restored with a full crown after part of the tooth tissue is removed. [0003] In the installation of fixed teeth, the bonding between the porcelain crown and the residual root of ...
