Description

Adjustable sleeve crown and mounting method thereof

Technical Field

The invention relates to the field of false teeth, in particular to an adjustable socket crown and an installation method thereof.

Background

The telescopic crown is a fixed-movable combined prosthesis. The coping is a double-layered crown having a high degree of tightness, in which an inner crown is fixed to an abutment and an outer crown is placed in a denture, and the denture is fixed by a frictional force generated by the close fit between the inner and outer crowns.

At present, the fixed friction that produces between the sleeve crown through inside, outside the hat carries out the maintenance, but the sleeve crown uses after the long time, because often contact between inside and outside the hat for the contact surface between inside and outside the hat from before comparatively crude become comparatively smooth, thereby make and take place relative slip easily between the inside and outside the hat, make and can't carry out the maintenance between the inside and outside hat, lead to droing of outer hat, finally influence the use of outer hat.

Disclosure of Invention

Aiming at the problem that the outer crown is easy to separate in the prior art, the invention aims to provide an adjustable sleeve crown which has the advantages that the outer crown is not easy to fall off, is more stable and is simple to mount.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following provides a detailed description of the present invention with reference to examples and drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1, an adjustable socket crown includes an abutment 1 placed in a gum, the abutment 1 being ground into a cylindrical shape from an original tooth. The outer side of the abutment 1 is provided with an inner crown 2 in a bonding mode, the inner crown 2 is fixed with the abutment 1 through an oral cavity adhesive 10, and anouter crown 3 is sleeved on the outer side of the inner crown 2.

The inner surface of the inner crown 2 is provided with afrosted layer 9, and anoral adhesive 10 is arranged between thefrosted layer 9 and the abutment 1. The contact area of theoral cavity adhesive 10 and the abutment 1 is increased through thefrosted layer 9, so that the inner crown 2 is firmer after being installed.

The top end of theouter crown 3 is provided with a through hole 4, the through hole 4 is positioned at the eccentric position of the top surface of theouter crown 3 and vertically penetrates through theouter crown 3, apositioning needle 5 penetrates through the through hole 4, thepositioning needle 5 is an elastic metal rod, the diameter of thepositioning needle 5 is 0.6mm-0.8mm, and the optimal diameter is 0.7 mm. The through hole 4 facilitates the later passage of thepositioning pin 5 through theouter crown 3.

Thepilot pin 5 includes integrativemain pole portion 51 andkink 52 that sets up, and the angle betweenmain pole portion 51 and thekink 52 is obtuse angle or right angle,main pole portion 51 joint in interior hat 2 with between theouter hat 3, theouter recess 6 withmain pole portion 51 joint adaptation is seted up to interior 2 outer walls of hat, theinner groovy 7 withmain pole portion 51 joint adaptation is seted up to interior 2 inner walls of hat. The space formed by theinner groove 7 and theouter groove 6 facilitates the insertion of thepositioning pin 5, and simultaneously reduces the gap between the inner crown 2 and theouter crown 3 in the process that themain rod part 51 of thepositioning pin 5 compresses the inner crown 2 and theouter crown 3.

Thebending part 52 is welded on the top surface of theouter crown 3 by laser welding, and the top surface of theouter crown 3 is provided with aslot 8 for embedding thebending part 52. The bendingpart 52 is clamped in the clampinggroove 8, so that the false tooth is more natural and the use is not influenced.

As shown in fig. 2, a method for installing an adjustable collet crown includes the steps of:

in step one (S10), the abutment 1 and the peripheral gingiva are cleaned by the mouth cleaner. The sanitation before installation is ensured by cleaning.

In step two (S20), the coping 2 is fixed to the outer side of the abutment 1 by theoral adhesive 10. The inner crown 2 needs to be provided with anouter groove 6 during the moulding process. The inner crown 2 is fixed outside the abutment 1 in a bonding way, so that the installation is stable and the abutment cannot shake.

And step three (S30), theouter crown 3 is sleeved outside the inner crown 2. Theouter crown 3 needs to be provided with aninner recess 7 during the moulding process. Theouter crown 3 is sleeved on the inner crown 2, and theinner groove 7 is opposite to theouter groove 6.

And step four (S40), thepositioning pin 5 penetrates through theouter crown 3 from the through hole 4, and themain rod part 51 of thepositioning pin 5 is clamped between theouter groove 6 of the inner crown 2 and theinner groove 7 of theouter crown 3. The inner crown 2 and theouter crown 3 are pressed tightly by thepositioning needle 5, and theouter crown 3 is prevented from loosening.

Step five (S50), the bendingpart 52 of thepositioning pin 5 is clamped in the clampinggroove 8 of theouter crown 3, and the bendingpart 52 is welded in the clampinggroove 8; thebent portion 52 is fixed to the top surface of theouter crown 3 by means of laser welding. The laser welding operation is convenient and fast, the accuracy is high, and the welding between the bendingpart 52 and theouter crown 3 is firmer.

Step six (S60), theouter crown 3 is cleaned by the mouth washer. Theouter crown 3 is cleaned again after being installed, and the sanitation after installation is guaranteed.

The working principle and the beneficial effects of the invention are as follows:

the crown 2 is fixed in the 1 outside bonding of abutment, and the 2 outside covers of crown hasouter crown 3, and thelocation needle 5 is installed in pegging graft on theouter crown 3, and themobile jib portion 51 joint oflocation needle 5 is between theouter recess 6 of the inner groovy 7 ofouter crown 3 and inner crown 2, and thekink 52 oflocation needle 5 welds in dying in the draw-ingroove 8 ofouter crown 3.

After theouter crown 3 covers on the inner crown 2, compress tightly the inner crown 2 and theouter crown 3 through thepilot pin 5, the laminating ofouter crown 3 and inner crown 2 is inseparabler, and then makes the frictional force increase betweenouter crown 3 and the inner crown 2, has avoided the droing thatouter crown 3 probably appears.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
