Problems solved by technology

[0004] The inventors found that the current method of adhesive-retained implant dentures also has deficiencies, such as the problem of adhesive residues, which may cause peri-implantitis; when repairing adhesive-retained implant dentures, use Appropriate methods to reduce or eliminate residual adhesive around implant dentures are necessary
At present, the most widely used adhesive-removing agent models are mostly silicone rubber or self-curing resin. Their disadvantage is that a suitable model must be designed for each denture, which can only be used once and is cumbersome, and the operation efficiency is relatively low. Low

Embodiment 1

[0033] In a typical implementation of the present disclosure, such as figure 1 As shown, an abutment substitute for dental crown cement is proposed.

[0034] It mainly includes cylinder 1, sliding pair and base. There are multiple cylinders with different diameters. Multiple cylinders are set coaxially in sequence according to the diameter. The adjacent cylinders are matched by sliding pairs so that the cylinders can Sliding toward reciprocating; the cylinder with the largest diameter is located at the outermost, and it is equipped with a base 5, which is used to facilitate the user to hold and place the device as a whole; to improve the efficiency and ease of operation when removing excess adhesive.

[0035] After all the cylinders are nested in order according to their diameters, a structure in which the first cylinder, the second cylinder, the third cylinder... One end is located in the second cylinder, and the other end sticks out of the second cylinder. When an external ...

Embodiment 2

[0056] In another typical implementation of the present disclosure, such as figure 1 As shown, a working method of abutment replicas for dental crown cements is proposed.

[0057] Include the following steps:

[0058] When the crown is bonded, the cement is placed in the crown drill hole;

[0059] Insert the small-diameter cylindrical end of the abutment replica into the drill hole of the crown filled with cement;

[0060] Gradually push the abutment model, so that the cylinder gradually fills the crown drill hole according to the diameter, until the next level cylinder cannot enter the drill hole;

[0061] During the cylinder filling process, the excess adhesive in the crown drill hole overflowed, and the abutment model was removed to leave an appropriate amount of adhesive in the crown drill hole;

[0062] The crown is installed in the patient's oral cavity by bonding and fixing it.

[0063] A section of spring is sheathed on each slide bar, which is in a free state at t...

Abstract

The invention provides an abutment substitute for a dental crown adhesive and a working method, and relates to the field of dental implants; the abutment substitute comprises a plurality of cylinderswhich are coaxially sleeved in sequence from inside to outside, wherein the adjacent cylinders are matched through sliding pairs; the sliding pairs are used for enabling the cylinders to axially movealong the adjacent cylinders, and the plurality of cylinders form a stepped shaft structure with variable axial length, thereby adapting to dental crown drill holes with different diameters; a steppedshaft-shaped telescopic structure is formed through a multi-stage sleeved cylinder structure, and the dental crown drill holes with different sizes are adapted by utilizing the diameter change of different sleeves, so that redundant adhesive in the dental crown drill holes is extruded in advance, and the adhesive is prevented from overflowing when the adhesive is fixed to an oral cavity bonding fixing position.

Description

technical field [0001] The disclosure relates to the field of dental implants, in particular to an abutment model for crown adhesive and a working method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Implant dentures have become a routine treatment option for repairing defective or missing dentition. The retention methods of implant fixed dentures can be divided into adhesive retention and screw retention. Adhesive-retained implant dentures are easy to operate clinically, and are closer to fixed restorations of natural teeth; compared with screw-retained implant dentures, it is easier to obtain passive seating of the crown; and the cost of clinical treatment is lower. Because there is no screw opening on the occlusal surface, it has good aesthetic effect, and it is not easy to loosen or break the screw, so it has better therapeutic e...
