Description

Technical Field

[0001] The utility model relates to an implant base capable of increasing friction retention and bonding, and belongs to the technical field of oral dental implants. Background Art

[0002] The implant abutment is an auxiliary device for implants in dental restorations. After the implant is surgically implanted, the implant abutment will also be permanently attached to the implant through surgery. The doctor generally installs the implant on the patient's dental bone. After healing is complete, the implant abutment is installed on the implant, and then the crown is bonded to the implant abutment through adhesives to achieve dental implantation.

[0003] However, the existing implant abutment and crown are only bonded by adhesives. Since the surface of the connection between the implant abutment and the crown is relatively smooth, the adhesion and gripping force of the adhesive on the surface of the implant abutment are insufficient. When people bite for a long time, the implant abutment and the crown are prone to relative slippage, causing the crown to loosen and dislocate.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an implant abutment with increased friction retention and bondable structure, which solves the problem that in the prior art, the implant abutment and the crown are bonded only by adhesives, and because the surface of the connection between the implant abutment and the crown is relatively smooth, the adhesion and gripping force of the adhesive on the surface of the implant abutment are insufficient. When people bite for a long time, the implant abutment and the crown are prone to relative slippage, resulting in loose and dislocated crowns.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a friction-retaining and bondable implant base, comprising a base, the base comprising a base connected to the implant and a connector for bonding to the crown, a plurality of protrusions and ridges being staggered and arranged at equal intervals along the circumferential direction on the connector, and grooves being formed between adjacent protrusions and ridges, an annular filling groove being provided at the bottom of the connector, and an annular fastening groove being provided at the top of the connector.

[0007] By adopting the above technical solution, when the staff needs to install a dental crown, they first connect the base to the implant, then apply the adhesive on the surface of the connector, and then snap the crown that matches the shape of the connector into the connector. As the crown is gradually snapped in, the adhesive is evenly and fully filled between the crown and the connector, thereby achieving a tight connection between the connector and the crown, and then realizing a tight connection between the implant and the crown through the implant base.

[0008] The arrangement of the protrusions, ridges and grooves allows the cross section of the connector to form an irregular cross section, thereby effectively preventing the crown from rotating after the crown is installed. In addition, the arrangement of the protrusions, ridges and grooves also increases the contact area between the crown and the connector, which not only increases the friction between the crown and the connector, but also makes the crown more firmly bonded after the adhesive is coated on the surface of the connector. When the crown is installed, the opening of the filling groove and the fastening groove allows a larger space between the crown and the connector to fill the adhesive. On the one hand, more adhesive can provide a better bonding effect, making the crown more firmly bonded. On the other hand, when the adhesive solidifies in the fastening groove and the filling groove and is bonded to the crown, the protrusion can limit the solidified adhesive, making it more difficult for the crown to be pulled out of the connector axially, thereby making the connection between the crown and the connector more stable, thereby avoiding relative slippage between the implant base and the crown, thereby effectively preventing the crown from shaking, dislocating or even falling off.

[0009] In addition, the bumps and ridges are arranged at equal intervals and their cross-sectional shapes are respectively fan-shaped and rectangular, which increases the contact area between the connector and the crown and allows the adhesive to be more evenly applied to the surface of the connector, thereby making the bonding between the crown and the connector more uniform and firm.

[0010] The utility model is further configured as follows: a pre-grinding body is fixed on the top of the connecting body, and scale lines are arranged on the pre-grinding body.

[0011] By adopting the above technical solution, when the staff needs to install the implant base on the implant, since the gum heights of the implants at different positions of the tooth bone are different, the staff can adjust the height of the pre-ground body so that after the crown is installed on the connector, the connector will not be exposed outside the gums due to being higher than the gums, thereby affecting the aesthetics of the implant. At the same time, the scale lines set on the pre-ground body allow the staff to adjust the pre-ground body layer by layer according to the scale, thereby facilitating the production of a matching crown.

[0012] The utility model is further configured as follows: the base comprises a fixed abutment seat in a truncated cone shape with a larger upper portion and a smaller lower portion, and a plug-in seat with a polygonal cross-section is fixed on the abutment seat. Preferably, the polygon is a regular hexagon.

[0013] By adopting the above technical solution, the abutment seat with a truncated cone shape and a larger top and a smaller bottom is easy for the staff to install, and the plug-in seat with a polygonal cross-section makes it impossible for the plug-in seat to rotate after it is inserted into the implant due to the limiting effect of the polygonal cross-section on the plug-in seat, thereby making the connection between the implant base and the implant more stable.

[0014] The utility model is further configured as follows: a first chamfer is arranged on the top of the connector along a circumferential direction, and a second chamfer is arranged on the bottom of the connector.

[0015] By adopting the above technical solution, under the guiding effect of the second chamfer, the connector is easier to insert into the implant, and under the guiding effect of the first chamfer, the crown is easier to fit into the connector.

[0016] The beneficial effects of the utility model are as follows: the arrangement of the protrusions, ridges and grooves makes the cross section of the connector form a special-shaped cross section, so that after the crown is installed, the crown can be effectively prevented from rotating. In addition, the arrangement of the protrusions, ridges and grooves also increases the contact area between the crown and the connector, which not only increases the friction between the crown and the connector, but also makes the crown more firmly bonded after the adhesive is coated on the surface of the connector; wherein, when the crown is installed, the opening of the filling groove and the fastening groove makes there be a larger space between the crown and the connector to fill the adhesive, on the one hand, more adhesive can provide a better bonding effect, so that the crown is more firmly bonded; on the other hand, when the adhesive is solidified in the fastening groove and the filling groove and bonded to the crown, the protrusion can limit the solidified adhesive, making it more difficult for the crown to be pulled out of the connector axially, thereby making the connection between the crown and the connector more stable, thereby avoiding the relative slippage between the implant base and the crown, thereby effectively preventing the crown from shaking, dislocating or even falling off.

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0027] like Figure 1 and Figure 5 As shown, an implant base with increased friction retention and bondable, includes a base 1, the base 1 includes a base 2 connected to the implant and a connector 3 for bonding to the crown, a plurality of protrusions 4 and ridges 5 are staggered and arranged at equal intervals along the circumferential direction on the connector 3, and grooves 7 are formed between adjacent protrusions 4 and ridges 5, an annular filling groove 6 is opened at the bottom of the connector 3, and an annular fastening groove 14 is opened at the top of the connector 3.

[0028] When the staff needs to install a dental crown, they first connect the base 2 to the implant, then apply the adhesive on the surface of the connector 3, and then snap the dental crown that matches the shape of the connector 3 into the connector 3. As the dental crown is gradually snapped in, the adhesive is evenly and fully filled between the dental crown and the connector 3, thereby achieving a tightening connection between the connector 3 and the dental crown, and then realizing a tightening connection between the implant and the dental crown through the implant base.

[0029] The arrangement of the protrusion 4, the ridge 5 and the groove 7 makes the cross section of the connector 3 form a special-shaped cross section, so that after the crown is installed, the crown can be effectively prevented from rotating. In addition, the arrangement of the protrusion 4, the ridge 5 and the groove 7 also increases the contact area between the crown and the connector 3, which not only increases the friction between the crown and the connector 3, but also makes the crown more firmly bonded after the adhesive is applied to the surface of the connector 3; wherein, when the crown is installed, the filling groove 6 and the fastening groove 14 are opened, so that there is a larger space between the crown and the connector 3. The space is filled with adhesive. On the one hand, more adhesive can provide better bonding effect, making the crown bonded more firmly; on the other hand, when the adhesive is solidified in the fastening groove 14 and the filling groove 6 and bonded together with the crown, the protrusion 4 can limit the solidified adhesive, making it more difficult for the crown to be pulled out of the connector 3 axially, thereby making the connection between the crown and the connector 3 more stable, thereby avoiding relative slippage between the implant base and the crown, and effectively preventing the crown from shaking, dislocating or even falling off.

[0030] In addition, the bumps 4 and the ridges 5 are arranged at equal intervals and their cross-sectional shapes are respectively fan-shaped and rectangular, which increases the contact area between the connector 3 and the crown and allows the adhesive to be more evenly applied to the surface of the connector 3, thereby making the bonding between the crown and the connector 3 more uniform and firm.

[0031] In one embodiment, if Figure 6 As shown, the filling groove 6 is spirally opened on the outer peripheral wall of the connecting body 3.

[0032] In another embodiment, if Figure 7 As shown, a plurality of filling grooves 6 of different heights are opened on the outer peripheral wall of the connector 3 along the circumferential direction.

[0033] In another embodiment, if Figure 8 As shown, a plurality of filling grooves 6 are obliquely opened on the outer peripheral wall of the connector 3 .

[0034] The above three ways of opening the filling groove 6 all allow for a larger space between the crown and the connector 3 to be filled with adhesive, thereby making the bonding between the crown and the connector 3 more stable. In addition, after the adhesive solidifies to form a block, the connection between the crown and the connector 3 is more stable due to the limiting effect of the adhesive block.

[0035] like Figure 1 As shown, a pre-grinding body 8 is fixed on the top of the connecting body 3 , and scale lines 9 are arranged on the pre-grinding body 8 .

[0036] When the staff needs to install the implant base on the implant, since the gum heights of different positions of the implant in the tooth bone are different, the staff can adjust the height of the pre-grinded body 8 so that after the crown is installed on the connector 3, the connector 3 will not be exposed outside the gums due to being higher than the gums, thereby affecting the aesthetics of the implant. At the same time, the scale lines 9 set on the pre-grinded body 8 allow the staff to adjust the pre-grinded body 8 layer by layer according to the scale, thereby facilitating the production of a matching crown.

[0037] like Figure 3 and Figure 4 As shown, the base 2 includes a fixed abutment seat 11 in a truncated cone shape with a larger upper portion and a smaller lower portion, and a plug-in seat 12 with a polygonal cross section is fixed on the abutment seat 11, preferably, the polygon is a regular hexagon. The truncated cone-shaped abutment seat 11 with a larger upper portion and a smaller lower portion is convenient for installation by the staff, and the plug-in seat 12 with a polygonal cross section makes it impossible for the plug-in seat 12 to rotate after the plug-in seat 12 is inserted into the implant, due to the limiting effect of the polygonal cross section on the plug-in seat 12, thereby making the connection between the implant base and the implant more stable.

[0038] like Figure 2As shown, a chamfer 10 is provided at the top of the connector 3 along a circumferential direction, and a chamfer 2 13 is provided at the bottom of the socket 12. Under the guidance of the chamfer 2 13, the socket 12 is easier to insert into the implant, and under the guidance of the chamfer 10, the crown is easier to fit into the connector 3.

[0039] Working principle:

[0040] When the staff needs to install the crown, first, under the guidance of the chamfer 13 and the abutment seat 11, the plug-in seat 12 is inserted into the implant, and the base 2 and the implant are connected by bolts. Then, according to the gum height of the implant location, the height of the pre-ground body 8 is adjusted layer by layer according to the scale line 9, and then the adhesive is applied to the surface of the connector 3. Specifically, the connector 3 includes a plurality of protrusions 4 and ridges 5 arranged at equal intervals and staggered in the circumferential direction, and grooves 7 formed between adjacent protrusions 4 and ridges 5, an annular filling groove 6 opened at the bottom of the connector 3, and an annular fastening groove 14 opened at the top of the connector 3. Therefore, the staff can, with the assistance of the guiding effect of the chamfer 10, smoothly insert the crown that matches the height of the pre-ground body 8 and the shape of the connector 3 into the connector 3. As the crown is gradually inserted, the adhesive is evenly and fully filled between the crown and the connector 3, thereby achieving the effect of a fastened connection between the connector 3 and the crown, and then realizing a fastened connection between the implant and the crown through the implant base.

[0041] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
