Dental implant assembly and its abutment

This creation relates to a dental implant component and its abutment, in particular to the use of a resilient abutment structure to prevent relative rotation between the implant and the abutment, and the tolerance between the locking bar and the abutment locking channel Gap, a dental implant component and its abutment that overcomes the problem of combined interference between the implant and the abutment due to a misalignment error.

Dental implant technology originated in the Middle Ages, when ancient Egyptians and South Americans used polished ivory and wood as dentures. Since the 19th century, people have tried to use different materials as dentures, which contain gold, platinum, ceramics and cobalt-chromium-molybdenum alloys. By the end of the twentieth century, dental implant technology had matured and there are now more than 200 dental implant systems.

Referring to the first figure, the first figure shows a schematic cross-sectional view of one of the dental implant components provided by the prior art. As shown in the figure, in the dental implant operation of a dental implant component PA1 which is now known, an implant PA11 is usually implanted first into a alveolar bone PA2 (shown in the third figure). After a few months, after the bones are fully developed and the implant PA11 is firmly locked to the alveolar bone PA2, the dentist will base the abutment by inserting the locking screw PA13 through a base channel PA121 of the abutment PA12. PA12 locks into implant implant PA11, one of the implant screw holes PA111, and depends on the patient's tooth knot The configuration determines the shape of the crown that is fixed to the base PA12.

However, the dental implant component PA1 provided by the prior art is a delicate component, which is a few millimeters. Referring to the second drawing, the second drawing shows a schematic cross-sectional view of a dental implant component having a tolerance abutment channel provided by the prior art. As shown in the figure, when the base station PA12' is fabricated, as long as the abutment path PA121' located in the base station PA12' has a slight angular or positional deviation, after a locking screw PA13 passes through the abutment passage PA121' The implant screw hole PA111, which is not allowed to be positioned in the implant PA11, often causes the locking screw PA13 to lock the abutment PA12' to the implant PA11.

Please refer to the third figure. The third figure shows a schematic cross-sectional view of the state in which the three abutments are locked together with three offset implants in the dental implant assembly provided by the prior art. As shown, when the patient needs to perform multiple adjacent implant operations, the dentist first implants three implants PA11, PA11a, and PA11b into the alveolar bone PA2. After the recovery period, the three bases PA12, PA12a, and PA12b connected to each other by the bridge PA3 are locked together in the implants PA11, PA11a, and PA11b.

However, when the dentist performs a dental implant operation, the implants PA11, PA11a, PA11b are implanted into the alveolar bone PA2 by the aid of the guide plate. However, even with the aid of tools, when the dentist manually implants the implants PA11, PA11a, and PA11b into the alveolar bone PA2, it is still difficult to avoid the positional deviation caused by human factors or the angular deviation of 1 to 2 degrees. Human error, thus causing the implants PA11, PA11a, PA11b to be non-parallel to each other when implanted into the alveolar bone PA2. At the same time, since the bases PA12, PA12a, and PA12b are connected by the bridge PA3, they cannot be adjusted. The relative position or angle between the respective base stations PA12, PA12a, PA12b. Under the limitations of the above-mentioned various conditions, when the denture is installed, it is often difficult to simultaneously connect the bases PA12, PA12a, and PA12b together by the bridge PA3 due to the non-parallelism between the implants PA11, PA11a, and PA11b. It is also difficult to simultaneously insert the implants PA11, PA11a, and PA11b into the implants PA11, PA11a, and PA11b and connect them to the bases PA12, PA12a, and PA12b which are integrally connected by the bridge PA3.

Zoom in on the schematic.

Please refer to the fourth to sixth figures. The fourth figure shows a three-dimensional assembly diagram of the dental implant component provided by the first embodiment of the present invention. The fifth figure shows the dental implant component provided by the first embodiment of the present creation. 3D exploded view; the sixth figure shows an exploded view of the AA section of the dental implant component provided by the first embodiment of the present invention. As shown, the present invention provides a dental implant component 1 disposed on a alveolar bone 2 (shown in FIG. 11). The dental implant component 1 includes an implant 11, a base 12 and a lock. element 13.

The implant 11 is further provided with an extracorporeal thread portion 111 for screwing the implant 11 to the alveolar bone 2. The implant body 11 defines a tapered limiting slot 112 defined by a limiting slot wall 1121. The tapered limiting slot 112 has an implant central axis L1. Preferably, the tapered limiting slot 112 is a polygonal tapered limiting slot. In the first embodiment, it is a hexagonal tapered limiting slot, and the polygonal tapered limiting slot is, for example, a pentagonal tapered limiting slot. With the octagonal tapered limit groove, the embodiment is too numerous to mention, so no more details are given.

The limiting groove wall 1121 includes a tapered groove wall portion 11211 and an abutting portion 11212. The tapered groove wall portion 11211 is a polygonal limiting groove wall (hexagonal limiting groove wall), but in practice, a conical limiting groove wall can also be used instead. The abutting engagement portion 11212 has an abutting engagement angle A1 with the implant central axis L1. In addition, the implant 11 further has a planting locking hole 113 extending from the tapered limiting slot 112 along the implant and the central axis L1, and the implant locking hole 113 is a screw hole.

The base 12 is coupled to the implant 11 and includes a tapered limiting portion 121, an elastic abutting portion 122 and a crown setting portion 123. A base locking passage 1211 is defined in the tapered limiting portion 121 along a central axis L2 of the base, and the base locking passage 1211 has a passage diameter D2. It is worth mentioning that the tapered groove wall portion 11211 is substantially in place and accommodates the tapered limiting portion 121 because the tapered limiting portion 121 has a tapered limit substantially matching the tapered limiting slot 112. Outer wall 1212.

In order to cooperate with the polygonal tapered limiting groove and the tapered groove wall portion 11211, the tapered limiting portion 121 is a polygonal pyramid having a polygonal pyramid structure. a limiting portion or a conical limiting portion of a conical structure. Wherein, the cooperation of the polygonal tapered limiting groove and the polygonal tapered limiting portion can effectively prevent relative rotation between the base 12 and the implant 11. In the first embodiment, the polygonal tapered limit portion is a hexagonal tapered limit portion, and the polygonal tapered limit portion is, for example, a pentagonal tapered limit portion and an octagonal tapered limit portion, which are implemented by There are countless examples, so I won’t repeat them. In addition, the tapered limiting outer wall 1212 has a limiting wall inclination angle A21 with the base central axis L2.

The elastic abutting top portion 122 includes a plurality of elastic abutting structures 1221 extending from the tapered limiting portion 121 and a plurality of end elastic abutting structures 1222 respectively connected to one end of the elastic abutting structure 1221 , and each elastic abutting structure 1221 is the top shrapnel of each other. The end elastic abutting structure 1222 is for increasing the friction between the base 12 and the implant 11, thereby preventing relative rotation between the base 12 and the implant 11.

The elastic abutting structure 1221 and the base central axis L2 have an abutting inclination angle A221 smaller than the limit wall inclination angle A21. In the sixth figure, the abutment inclination angle A221 is the abutment central axis L2 and the elastic abutment. The angle between the outer walls of the structure 1221. In more detail, the abutting engagement angle A1 is greater than the abutment inclination angle A221 such that the resilient abutting structure 1221 abuts against the abutting engagement portion 11212. In addition, the end elastic abutting structure 1222 and the base central axis L2 have an end structure inclination angle A222, and the end structure inclination angle A222 is greater than the abutment inclination angle A221. Therefore, the end resilient abutment structure 1222 has the effect of assisting the guiding base 12 to more easily enter the tapered limiting slot 112. In the sixth diagram, the end structure inclination angle A222 is the angle between the abutment central axis L2 and the outer wall of the end elastic abutment structure 1222. Further, the crown setting portion 123 is coupled to the elastic abutting portion with respect to the tapered stopper portion 121. The other end of the portion 122 extends out.

The locking element 13 includes a locking head 131 and a locking rod 132. The locking head 131 has a locking head diameter D31, and the locking head diameter D31 is larger than the channel diameter D2, so that the locking head 131 can be caught in one of the locking passages 12111 of the abutment locking passage 1211 without entering the abutment. Locking channel 1211.

The locking rod body 132 extends from the locking head 131 and is fixed to the implant 11 through the base locking channel 1211 , so that the base 12 is fixed to the implant 11 by the locking component 13 , and The locking rod body 132 has a rod diameter D32, and the rod body diameter D32 is smaller than the passage diameter D2, and a tolerance gap G is formed between the base locking passage 1211 and the locking rod body 132 (the display is shown in the eighth figure). ).

The channel diameter D2 is about 1.05 to 1.3 times the diameter D32 of the rod. For example, if the diameter D32 of the rod is 2 mm, the diameter D2 of the passage ranges from about 2.1 mm to 2.6 mm, because the embodiment is innumerable. So, so no more details. In addition, a locking thread portion 1321 is disposed at one end of the locking rod body 132 away from the locking head 131. The locking element 13 is screwed to the implant locking hole 113 by the locking thread portion 1321. That is, the locking rod body 132 is locked to the implant locking hole 113.

Please refer to the seventh to ninth drawings. The seventh figure shows a three-dimensional schematic diagram of the dental implant component and the crown provided by the first embodiment of the present invention before being assembled. The eighth figure shows the first embodiment of the present creation. The schematic diagram of the dental implant component and the crown provided before the assembly; the ninth figure shows the profile of the dental implant component and the crown provided by the first embodiment of the present invention. As shown, in the ideal state When the implant is implanted, a crown 31 is placed in the crown setting portion 123. When the base 12 is coupled to the implant 11, the elastic abutting structure 1221 will be smaller than the limit wall inclination angle A21 (shown in the sixth figure) because of the abutment inclination angle A221 (shown in the sixth figure), and the cone-shaped limit The position portion 121 first abuts against the limiting groove wall 1121. More precisely, the resilient abutment structure 1221 will abut against the abutment mating portion 11212, thereby inhibiting relative rotation between the abutment 12 and the implant 11.

It is worth mentioning that, in the plurality of elastic abutting structures 1221, there are six elastic abutting structures 1221 corresponding to the six corners of the hexagonal tapered limiting slots, which are abutted against the top matching portion 11212. The six corners, the friction between the six elastic abutting structures 1221 and the abutting mating portions 11212 to suppress relative rotation between the abutment 12 and the implant 11 are most pronounced.

Please refer to the tenth figure. The tenth figure shows a schematic cross-sectional view of the abutment locking channel with the tolerance of the dental implant component provided by the first embodiment of the present invention. In general, when manufacturing the implant 11 and the base 12, there are inevitably some manufacturing tolerances. The so-called manufacturing tolerances are likely to also include a misalignment error E present between the implant central axis L1 and the abutment central axis L2. Even if the misalignment error E exceeds a tolerance range, the locking rod body 132 can pass through the abutment locking channel 1211 through the tolerance gap G, thereby being fixed to the implant 11. Since the locking lever 132 can be finely adjusted in position or angle in the tolerance gap G, the locking member 13 can be smoothly locked into the implant locking hole 113. The tolerance gap G allows the locking rod 132 to be adjusted for angular deflection of 0 to 30 degrees. Having explained in more detail, because of the tolerance gap G between the abutment locking channel 1211 and the locking element 13, the axial direction of the locking rod 132 is achieved when the locking rod body 132 is in the abutment locking channel 1211. Abutment center axis L2 can have a maximum of 30 degrees Tolerance angle. Here, in the tenth figure, the misalignment error E is caused by the slight tilting of the abutment locking passage 1211 to the left (counterclockwise direction) when the base 12 is manufactured. However, the offset error E can be an angular offset error. Simply put, the base locking channel 1211 is too skewed and the angle is offset from the center axis L2 of the base. In addition, the offset error E may also be a positional offset error, that is, the base locking channel 1211 is not opened at an ideal position, and the position is offset from the center axis L2 of the base.

Please refer to the eleventh and twelfth drawings. The eleventh figure shows the cross-sectional view of the implant-fitted bridge with the error of the plurality of dental implant components provided by the second embodiment of the present invention. The second figure shows a partial enlarged view of the B area of the eleventh figure. As shown in the figure, when the dentist implants the three implants 11, 11a, 11b into the alveolar bone 2, it is difficult to avoid human error during implantation, and thus the three implants 11, 11a, 11b cannot be used. Positioned at ideal positions and angles, causing them to be non-parallel to each other.

In the eleventh figure, the implants 11, 11a, 11b are not parallel to each other, wherein the implant 11 is slightly tilted toward the counterclock, and the implant 11b is slightly inclined toward the clock, thereby causing the implant 11 and the base 12 Another type of misalignment error occurs between the implant 11b and the base 12b. When the three bases 12, 12a, 12b connected by the bridge 32 are locked to the implants 11, 11a, 11b, the bases 12, 12a, 12b each have a tolerance gap G, Ga, Gb, The three locking elements 13, 13a, 13b can be finely adjusted in the tolerance gaps G, Ga, Gb, respectively, and finally smoothly locked into the implant locking holes 113, 113a, 113b.

In summary, in the case of a single-toothed dental implant component, A frictional force is generated between the elastic abutting structure and the abutting engagement portion, and a structural fitting condition of the rotational interference between the six corners of the elastic abutting structure and the hexagonal tapered limiting groove; Therefore, the relative rotation between the implant and the base can be effectively suppressed.

In the case of a multi-toothed dental implant component, when there is a misalignment error between the central axis of the implant and the central axis of the abutment, the locking element can be angled and positioned by the tolerance gap in the abutment locking channel. Fine adjustment, you can smoothly lock the implant locking hole. Therefore, when implanting a multi-toothed dental implant component at the same time, the tolerance gap of each dental implant component can reduce the influence of the misalignment error of each implant, so that the locking component can be smoothly locked into the implant locking. hole. In addition, the elastic deformation of the elastic abutting structure and the guiding of the end elastic abutting structure enable the plurality of abutments connected by the bridge to be smoothly combined with the plurality of implants. Therefore, a plurality of implants connected by a bridge can simultaneously lock a plurality of implants, or a plurality of bases joined together by a bridge can be taken out from a plurality of implants at the same time.
