Technical Field

The disclosure relates to the field of dental implants, in particular to an abutment substitute for a dental crown adhesive and a working method.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Implant dentures have become a common treatment option for repairing defects or missing dentition, and the retention of implant-fixed dentures can be divided into adhesive retention and screw retention. The bonding retention implant denture is simple and convenient in clinical operation and is closer to the fixation and repair of natural teeth; passive seating of the crown is more easily achieved than with a screw retained implant prosthesis; the clinical treatment cost is lower. Because the occlusal surface of the artificial tooth has no screw hole, the artificial tooth has good aesthetic effect, is not easy to loosen or damage the screw and has better treatment effect in clinical practice.

The inventors have found that the current approach of adhering a retention implant denture is also deficient, such as it presents adhesive residue problems that can lead to peri-implantitis; in bonded-retention implant denture repairs, it is necessary to use appropriate methods to reduce or eliminate residual adhesive around the implant denture. At present, most widely used adhesive removing substitutes are silicone rubber or self-setting resin, and the defects are that a suitable substitute is designed for each denture, the denture can be used only once and is relatively complex, and the operation efficiency is low.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide an abutment substitute for a dental crown adhesive and a working method thereof.

The first purpose of the disclosure is to provide an abutment substitute for a dental crown adhesive, which adopts the following technical scheme:

the dental crown drilling device comprises a plurality of cylinders which are coaxially sleeved from inside to outside in sequence, wherein adjacent cylinders are matched through a sliding pair, the sliding pair is used for enabling the cylinders to axially move along the adjacent cylinders, and the plurality of cylinders form a stepped shaft structure with variable axial length and are used for adapting to dental crown drilling holes with different diameters.

Further, the diameters of the cylinders are different, and the interiors of the cylinders are sequentially communicated along the axial direction.

Furthermore, the outer wall of any cylinder is attached to the inner wall of the adjacent cylinder sleeved outside the cylinder.

Further, the sliding pair comprises a sliding rod and a sliding block matched with the sliding rod, and the sliding rod and the sliding block are respectively installed on two adjacent cylinders and used for enabling one cylinder to slide relative to the other cylinder along the axial direction.

Further, the slide rod is installed inside the cylinder with the larger diameter in the two adjacent cylinders, the slide block is installed at the end of the other cylinder, and the arrangement direction of the slide rod is parallel to the axis of the cylinder.

Further, the sliding pair is matched with an elastic piece for pushing the sliding block to enable any cylinder to protrude out of the interior of the cylinder adjacent to the sliding block.

Further, each cylinder is matched with at least one sliding rod, and when one cylinder is matched with a plurality of sliding rods, the sliding rods are uniformly arranged relative to the axis of the cylinder.

Further, the cylinder with the largest diameter is matched with a base for receiving the external force to drive the axial expansion and contraction of the cylinder.

A second object of the present disclosure is to provide a working method of an abutment model for a crown cement, comprising the steps of:

inserting the small-diameter cylindrical end of the abutment model into the dental crown drill hole filled with the adhesive;

gradually pushing the abutment to substitute the model, so that the cylinder is gradually filled into the dental crown drill hole according to the diameter until the next-stage cylinder cannot enter the drill hole;

in the process of filling the cylinder, excessive adhesive in the dental crown drill hole overflows, and the abutment substitute is removed to ensure that a proper amount of adhesive remains in the dental crown drill hole;

the dental crown is arranged in the oral cavity of the patient and is fixed in place by adhesion.

Further, different cylinders are compatible with different sized crown bores.

Compared with the prior art, the utility model has the advantages and positive effects that:

(1) the dental crown drilling tool is filled into a dental crown drilling hole by adopting a multi-stage sleeved telescopic structure, and the volume of a sleeve entering the dental crown drilling hole is increased along with continuous pushing, so that the dental crown drilling hole can be more properly filled, and redundant adhesive overflows, thereby avoiding the problem of peri-implantitis caused by the overflow and residual of the adhesive when the dental crown is arranged in an oral cavity adhesion fixing position;

(2) the elastic piece is matched with the sliding pair, when external force is not applied, the elastic piece pushes the cylinder out to form a multi-stage stepped shaft structure, when the multi-stage stepped shaft structure is used, the multi-stage stepped shaft structure is gradually contracted from the small-diameter cylinder end, so that the cylinder with the gradually increased diameter gradually enters the drill hole, the gradual extrusion of the adhesive is realized, the uniform distribution of the adhesive remained on the drill hole of the dental crown is ensured, and the subsequent adhesive effect is improved;

(3) the base is configured on the largest cylinder, so that a user can conveniently hold the base, and the efficiency and the operation convenience in removing the redundant adhesive are improved.
