Description

[Technical field]

[0001] SUMMARY The present disclosure relates to dental components and methods for aligning dental components. [Background technology]

[0002] 2. Description of Related Art A dental prosthetic system can include components such as dental implants, intermediate components such as abutments, and prostheses such as crowns and bridges. An impression or scan of the implant site can be used to record information about the implant in the patient's mouth and aid in the manufacture of the prosthesis and / or intermediate component. In some cases, a coping (e.g., an impression coping or scan) can be mated with the dental implant or intermediate component to help record the position and orientation of the implant or intermediate component in the patient's mouth.

[0003] For implants and / or abutments having a non-circular interface or contour, it may be desirable to know the rotational position of the base component so that the upper component can be registered (e.g., aligned) to the base component. In other words, to allow the non-circular interface or contour of the upper component to be aligned to the non-circular interface or contour of the base component. For some components, such as bridges, it may also be desirable to provide non-engaging surfaces that can allow for some "play" between the bridge and base components, which can complicate mating with the non-circular base component. Summary of the Invention

[0004] A variety of dental components are provided. Systems and methods for aligning dental components are also provided. In some embodiments, the systems and methods can be used to create an upper component (e.g., a crown or bridge) that does not engage with a base component (e.g., an intermediate component or an implant), but can still be aligned with the orientation of the base component.

[0005] In certain embodiments, the system can be configured to record the position and orientation of the dental component. The system can include a coping and a replica. The coping can include an anti-rotation feature configured to mate with an anti-rotation feature of the dental component. The coping can also include an orientation feature configured to communicate an orientation of the dental component. The replica can include a first anti-rotation feature that corresponds to the anti-rotation feature of the dental component. The replica can also include a second anti-rotation feature that does not correspond to the anti-rotation feature of the dental component.

[0006] In some cases, the coping may include an impression coping configured to be embedded in an impression medium to record the position and orientation of the dental component. In some cases, the coping may include a scanner configured to be scanned to record the position and orientation of the dental component.

[0007] In various embodiments, the coping can include an outer surface that includes an orientation feature. The coping can also include an inner surface that includes an anti-rotation feature. In some cases, the orientation feature and / or the anti-rotation feature of the coping can include a protrusion, indentation, pin, or groove.

[0008] In some cases, the second anti-rotation feature of the replica can be disposed on the first anti-rotation feature of the replica. In some cases, the second anti-rotation feature of the replica can be disposed on a surface configured to mate with an adjacent component. The adjacent component can include a coping, an abutment, and / or a prosthesis. In some cases, the first anti-rotation feature and / or the second anti-rotation feature of the replica can include a protrusion, a recess, a pin, or a groove.

[0009] In some embodiments, the system can further include a dental component. The dental component can include a dental implant or an adapter configured to mate with the dental implant.

[0010] In various embodiments, the system can be configured to align the dental component with another dental component. The dental component can have a non-circular outer cross-sectional boundary. For example, the non-circular outer cross-sectional boundary can include a three-ellipse or four-ellipse boundary. In some embodiments, the system can further include another dental component. The other dental component can be configured to mate with the second anti-rotation feature of the replica but not with the first anti-rotation feature of the replica. The other dental component can include an abutment and / or a prosthesis.

[0011] In certain embodiments, a method of manufacturing a second dental component configured to align with the first dental component in a patient's mouth can be provided. The method can include mating a replica with a coping. The coping can have an orientation feature recorded with respect to the first dental component to communicate a position and orientation of the first dental component in the patient's mouth. The replica can include a first anti-rotation feature that corresponds to the anti-rotation feature of the first dental component. The replica can further include a second anti-rotation feature that does not correspond to the anti-rotation feature of the first dental component. The method can also include forming a model of at least a portion of the patient's mouth adjacent the replica mated with the coping. The method can also include disengaging the coping from the replica. The method can further include creating the second dental component such that the second dental component is configured to mate with the second anti-rotation feature of the replica but not with the first anti-rotation feature of the replica.

[0012] In various embodiments, the method may further include mating the coping with the first dental component. The coping may include an anti-rotation feature configured to mate with an anti-rotation feature of the first dental component. The method may further include recording an orientation feature of the coping mated with the first dental component to record a position and orientation of the first dental component. The method may also include disengaging the coping from the first dental component.

[0013] In some methods, the orientation features are recorded by embedding the orientation features in an impression medium. In some methods, the orientation features are recorded by scanning the orientation features.

[0014] In some methods, the first dental component and the second dental component can have a non-circular outer cross-sectional boundary. For example, the non-circular outer cross-sectional boundary can include a three-ellipse or four-ellipse boundary.

[0015] In some cases, the first dental component can be a dental implant or an adapter configured to mate with a dental implant.

[0016] In some embodiments, creating the second dental component may include creating an abutment and / or a prosthesis.

[0017] In certain embodiments, the replica can be configured to communicate an orientation of the first dental component to the second dental component. The replica can include an outer surface including a first anti-rotation feature and a second anti-rotation feature. In some embodiments, the first anti-rotation feature corresponds to an anti-rotation feature of the first dental component and the second anti-rotation feature does not correspond to an anti-rotation feature of the first dental component.

[0018] In some embodiments, the replica can be configured to mate with an anti-rotation feature of the coping to replicate the position and orientation of the first dental component.

[0019] In some cases, the replica can be configured to mate with the second dental component via a second anti-rotation feature of the replica, but not via a first anti-rotation feature of the replica.

[0020] In some cases, the first anti-rotation feature and / or the second anti-rotation feature of the replica may include a protrusion, a depression, a pin, or a groove.

[0021] In certain implementations, the multi-unit prosthesis can be configured to align with the dental component. The multi-unit prosthesis can include anti-rotation features. In some cases, the anti-rotation features can be configured to mate with anti-rotation features of a replica of the dental component. In some cases, the anti-rotation features of the prosthesis can be configured not to mate with anti-rotation features of the dental component. [Brief description of the drawings]

[0023] FIG. 1 is a schematic diagram of an exemplary dental component and an exemplary workflow. One or more dental components may be provided with a system and / or method for aligning the dental components. One of the components may be a base component, such as a component implanted in a patient's mouth. By way of example, the base component may be a dental implant or an intermediate component (e.g., an adapter) coupled to a dental implant. Another component may be an upper or lower component coupled (directly or indirectly) to the base component. For example, the upper component may be an abutment, a prosthesis, or a prosthesis coupled to an abutment. The exemplary systems and methods may be advantageously used to align dental components having non-circular outer cross-sectional boundaries (e.g., tri-ellipse boundaries, tetra-ellipse boundaries, etc.) and / or multi-unit prostheses (e.g., bridges) also having non-circular outer cross-sectional boundaries.

[0024] In summary, the system 1 (and / or workflow) can include any one or more of the following components: a base component 10, a coping 20, a replica 30, and / or an upper component 40. The system 1 can include any one, two, three, or all four components alone or in combination with other components. In some cases, the system 1 can be configured to record the position and orientation of the base component 10. The base component 10 can have an anti-rotation feature 11. In some embodiments, the system 1 can include a coping 20. The coping 20 can include an anti-rotation feature 21 configured to mate with the anti-rotation feature 11 of the base component 10. The coping 20 can also include an orientation feature 23 configured to communicate the orientation of the base component 10. In some embodiments, the system 1 can include a replica 30 (e.g., configured to replicate the position and orientation of the base component 10). The replica 30 can include a first anti-rotation feature 31 and a second anti-rotation feature 32. The first anti-rotation feature 31 may correspond to the anti-rotation feature 11 of the base component 10, while the second anti-rotation feature 32 does not correspond to the anti-rotation feature 11 of the base component 10. Thus, the first anti-rotation feature 31 may be configured to mate with the anti-rotation feature 21 of the coping 20, unlike the second anti-rotation feature 32 of the replica 30. In some embodiments, the system 1 may include an upper component 40 (e.g., an abutment and / or a prosthesis). The upper component 40 may include an anti-rotation feature 42 configured to mate with the second anti-rotation feature 32 of the replica 30, but not with the first anti-rotation feature 31 of the replica 30. During use, the orientation of the base component 10 may be communicated to the replica 30 via the anti-rotation feature 21 of the coping 20 and to the upper component 40 via the second anti-rotation feature 32 of the replica 30.Thus, the upper component 40 (and / or any component coupled to the upper component 40) may be aligned with the base component 10. However, because the upper component 40 does not mate with the first anti-rotation feature 31 of the replica 30, the upper component 40 also does not mate with the first anti-rotation feature 11 of the base component 10. Thus, "play" may be provided between the base component 10 and the upper component 40.

[0025] Each of the components is described in further detail below.

[0026] In some embodiments, the system 1 may include a base component 10. The base component 10 may be a component that is at least partially implanted below the gum line of the patient's mouth. Thus, the base component 10 is not limited to a component that is coupled to the patient's mandible, but may be coupled to the patient's maxilla. In some embodiments, the base component 10 may be a dental implant or an intermediate component (e.g., an adapter or an abutment) configured to mate (e.g., directly or indirectly) with a dental implant. The base component 10 may have an anti-rotation feature 11 configured to mate (e.g., engage or index) with another component, for example, to reduce and / or prevent rotational movement between the components. The number of anti-rotation features 11 is not particularly limited. For example, the anti-rotation feature 11 of the base component 10 may have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. anti-rotation features, or a range of numbers formed by such values ​​(e.g., 1 to 10 features, etc.).

[0027] In FIG. 1 , the anti-rotation feature 11 is disposed on the outer surface of the base component 10. However, the anti-rotation feature 11 may be disposed on the inner surface of the base component 10. In some examples, the anti-rotation feature 11 may be disposed on both the outer and inner surfaces of the base component 10. The number and size of the anti-rotation feature 11 are not particularly limited. When an anti-rotation feature 11 includes multiple anti-rotation features, one of the anti-rotation features may be the same as another of the anti-rotation features, or one of the anti-rotation features may be different from another of the anti-rotation features. The anti-rotation feature 11 may include a protrusion, a recess, a pin, a groove, a snap-fit ​​feature, and the like. In the example shown in FIG. 1 , the anti-rotation feature 11 of the base component 10 includes two anti-rotation features (e.g., two protrusions) that can mate with the coping 20.

[0028] In some embodiments, the system 1 may include a coping 20. Referring to FIG. 1, the coping 20 has an anti-rotation feature 21 configured to mate with the anti-rotation feature 11 of the base component 10. By mating with the anti-rotation feature 11 of the base component 10, the coping 20 may transmit (and / or communicate) the position and orientation of the base component 10 to another component (e.g., via the anti-rotation feature 21). The anti-rotation feature 21 of the coping 20 may complement the anti-rotation feature 11 of the base component. In the example shown in FIG. 1, the anti-rotation feature 21 of the coping 20 (e.g., two recesses) may mate with the anti-rotation feature 11 of the base component 10 (e.g., two protrusions). Since the anti-rotation feature 21 of the coping 20 may complement the anti-rotation feature 11 of the base component 10, as well as the anti-rotation feature 21 of the base component 10, the number of the anti-rotation features 21 of the coping 20 is not particularly limited. For example, the anti-rotation features 21 of the coping 20 can include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. anti-rotation features, or can have a range of numbers of anti-rotation features formed by such values ​​(e.g., 1 to 10 features, etc.).

[0029] The anti-rotation feature 21 can be located on the inner surface of the coping 20 (e.g., when the anti-rotation feature 11 of the base component 10 is on the outer surface of the base component 10), the outer surface of the coping 20 (e.g., when the anti-rotation feature 11 of the base component 10 is on the inner surface of the base component 10), or on both the inner and outer surfaces of the coping 20 (e.g., when the anti-rotation feature 11 of the base component 10 is on both the outer and inner surfaces of the base component 10). In FIG. 1 , the anti-rotation feature 21 of the coping 20 is located on the inner surface (e.g., to mate with the anti-rotation feature 11 on the outer surface of the base component 10). The number and size of the anti-rotation feature 21 are not particularly limited. When the anti-rotation feature 21 includes multiple anti-rotation features, one of the anti-rotation features can be the same as another of the anti-rotation features, or one of the anti-rotation features can be different from another of the anti-rotation features. The anti-rotation features 21 may include protrusions, indentations, pins, grooves, snap-fit ​​features, etc. As described herein, by mating with the anti-rotation features 11 of the base component 10, the coping 20 may communicate the position and orientation of the base component 10 (e.g., via the anti-rotation features 21).

[0030] The coping 20 may also include an orientation feature 23. The orientation feature 23 may be configured to provide an orientation for the coping 20 such that the position and orientation of the foundation component 10 may be captured, for example, in a recording medium. In some cases, the coping 20 may include an impression coping. The impression coping may be configured to be embedded in an impression medium (schematically represented by reference 25 in step 1B of FIG. 1) to record the position and orientation of the foundation component 10. The impression coping may be a transfer or pick-up type coping. The impression medium may be any known in the art or yet to be developed. For example, the impression medium may include a curable resin. In some cases, the coping 20 may include a scanning body. The scanning body may be configured to be scanned to record the position and orientation of the foundation component 10. The scanning body may be scanned using any technique known in the art or yet to be developed. For example, the scanning body may be scanned optically. In other examples, the scanning body may be scanned mechanically.

[0031] The orientation feature 23 can include protrusions, indentations, pins, grooves, and the like. In some cases, the orientation feature 23 can include an edge of the coping 20. For example, in the example shown in FIG. 1, the coping 20 has an orientation feature 23 that includes an edge of an outer surface. In some cases, if the base component 10 has an outer cross-sectional boundary that is not circular (e.g., non-circular), the orientation feature can be the outer cross-sectional shape, e.g., a three-ellipse boundary, a four-ellipse boundary. In various embodiments, the coping 20 can have an outer surface that includes the orientation feature 23. In some embodiments, the coping 20 can have an inner surface that includes the orientation feature 23. In some examples, the orientation feature 23 of the coping 20 can be located on both the outer surface and the inner surface. As described herein, the coping 20 can communicate the position and orientation of the base component 10 in a recording medium and / or to another component, such as a replica 30.

[0032] With continued reference to FIG. 1 , the system 1 may include a replica 30. The replica 30 may be configured to replicate the position and orientation of the base component 10 and / or communicate the orientation of the base component 10 to the upper component 40. For example, the replica 30 may include a first anti-rotation feature 31. The first anti-rotation feature 31 may correspond to the anti-rotation feature 11 of the base component 10. Thus, the first anti-rotation feature 31 of the replica 30 may be configured to mate with the anti-rotation feature 21 of the coping 20 to replicate the position and orientation of the base component 10 of the coping 20. Because the first anti-rotation feature 31 of the replica 30 may correspond to the anti-rotation feature 11 of the base component 10, the number, shape, and / or size of the first anti-rotation feature 31 are also not particularly limited. Also, similar to the anti-rotation feature 11 of the base component 10, the first anti-rotation feature 31 of the replica 30 can be located on the exterior surface, the interior surface, or both the exterior and interior surfaces of the replica 30. The first anti-rotation feature 31 can include protrusions, dimples, pins, grooves, snap-fit ​​features, and the like.

[0033] The replica 30 may also include a second anti-rotation feature 32. The number, shape, and / or size of the second anti-rotation feature 32 are not particularly limited. Also, the second anti-rotation feature 32 of the replica 30 may be located on the outer surface, the inner surface, or both the outer surface and the inner surface of the replica 30. The second anti-rotation feature 32 may include a protrusion, a recess, a pin, a groove, a snap-fit ​​feature, and the like. In FIG. 1, the second anti-rotation feature 32 of the replica 30 does not correspond to the anti-rotation feature 11 of the base component 10 and therefore does not mate with the anti-rotation feature 21 of the coping 20. As shown in FIG. 1, the second anti-rotation feature 32 of the replica 30 may extend from the first anti-rotation feature 31. In some cases, the second anti-rotation feature 32 may be located on the first anti-rotation feature 31. In some cases, the second anti-rotation feature 32 may be located separately from the first anti-rotation feature 31. For example, the second anti-rotation feature 32 may be disposed on a surface configured to mate with an adjacent component (eg, the coping 20, the upper component 40, etc.).

[0034] By mating with the anti-rotation feature 21 of the coping 20 (e.g., via the first anti-rotation feature 31) and with the upper component 40 (e.g., via the second anti-rotation feature 32), the replica 30 can communicate the orientation of the base component 10 to the upper component 40. Thus, the upper component 40 can be aligned with the base component 10. In other words, if the upper component 40 and the base component 10 each have an outer cross-sectional boundary surface that is not a circle (e.g., non-circular), the outer cross-sectional boundary surfaces of both non-circular shapes (e.g., non-circular) can be aligned. For some upper components 40, e.g., multi-unit prostheses such as bridges, it may be desirable to provide a non-engagement surface that can allow some "play" between the upper component 40 and the base component 10. In some such cases, as described with respect to upper component 40, a first anti-rotation feature 31 of replica 30 (corresponding to anti-rotation feature 11 of base component 10) may be configured not to mate with upper component 40.

[0035] For example, with continued reference to Figure 1, the upper component 40 can be a component that is coupled to the base component 10 and configured to be implanted above the gum line in a patient's mouth. Thus, the upper component 40 can be a component that is coupled to the patient's mandible or maxilla. In some embodiments, the upper component 40 can be an abutment and / or a prosthesis (e.g., a single or multi-unit prosthesis).

[0036] Through the transfer of orientation between the components, the upper component 40 can be configured to align with the base component 10. For example, the first anti-rotation feature 31 of the replica 30 can correspond to the anti-rotation feature 11 of the base component 10, and the upper component 40 can be configured to mate with the second anti-rotation feature 32 of the replica 30. In some cases, the base component 10 and the upper component 40 can have a non-circular outer cross-sectional interface, e.g., a three-ellipse interface, a four-ellipse interface, etc. In some cases (e.g., when the upper component 40 is an intermediate component such as an abutment), a prosthesis can be manufactured to mate with the upper component 40 such that the prosthesis can align with the base component 10. As described herein, the upper component 40 can be a multi-unit (or multi-tooth) prosthesis (e.g., a bridge) or one or more abutments that can be coupled to a multi-unit prosthesis. In some cases, the multi-unit prosthesis can include an anti-rotation feature 42. The anti-rotation feature 42 can be configured to mate with the second anti-rotation feature 32 of the replica 30. On the other hand, the anti-rotation feature 42 can be configured not to mate with the first anti-rotation feature 31 of the replica 30 that corresponds to the anti-rotation feature 11 of the base component 10. Thus, the multi-unit prosthesis can be configured to contact the base component 10, but "play" about at least one axis is permitted between the multi-unit prosthesis and the base component 10.

[0037] As an example of a workflow, a base component 10 can be placed in the patient's mouth. A coping 20 (e.g., an impression coping or a scan) can be positioned to mate with the base component 10 (see step 1A of FIG. 1). In some cases, an anti-rotation feature 21 of the coping 20 can mate with an anti-rotation feature 11 of the base component 10. An orientation feature 23 of the coping 20 mated with the base component 10 can be recorded to record the position and orientation of the base component 10 relative to its environment (i.e., adjacent teeth and soft tissues). The coping 20 can be disengaged from the base component 10. A replica 30 can be mated with the coping 20 (see, e.g., a recording medium, 1 of step 1B). The orientation feature 23 can be recorded with respect to the base component 10 to communicate the position and orientation of the base component 10 in the patient's mouth. A model 55 of at least a portion of the patient's mouth can be formed adjacent the replica 30 mated with the coping 20. The coping 20 (e.g., with the recording medium 25) can be disengaged from the replica 30, leaving the replica 30 in the model (see step 1C in FIG. 1). The upper component 40 (e.g., an abutment and / or a prosthesis) can be created such that the upper component 40 can mate with the second anti-rotation feature 32, but not with the first anti-rotation feature 31 of the replica 30 (see step 1C in FIG. 1). In this example, the first anti-rotation feature 31 of the replica 30 can correspond to the anti-rotation feature 11 of the base component 10, so that the upper component 40 is also not mated with the anti-rotation feature 11 of the base component 10. The upper component 40 can mate with the second anti-rotation feature 32 of the replica 30, but can be configured not to mate with the base component 10, because the base component 10 does not have a feature corresponding to the second anti-rotation feature 32.Once manufactured, the upper component 40 can be disengaged from the replica 30 and placed in an aligned but unengaged state on the base component 10 (see step 1D of FIG. 1).

[0038] 2-11 show other exemplary dental components and / or systems 100 that may include any one or more of the following components: a base component 110, a coping 120, a replica 130, and / or an upper component (e.g., an abutment and / or a prosthesis) 140. FIG. 2 shows an exemplary base component 110 having an anti-rotation feature 111 (e.g., three protrusions). The base component 110 has a non-circular profile. FIG. 3 shows an exemplary coping 120 having an anti-rotation feature 121 (e.g., three recesses) that may mate with the anti-rotation feature 111 of the base component 110 shown in FIG. 2. The exemplary coping 120 also includes an orientation feature 123 disposed opposite the anti-rotation feature 121. The orientation feature 123 may take the form of a non-circular profile. FIG. 4 shows an exemplary system 100 that may include one of the following components: an exemplary base component 110 and / or an exemplary coping 120. Figure 4 shows a cross-section of the base component 110 shown in Figure 2 coupled with the coping 120 shown in Figure 3. In Figure 4, the anti-rotation feature 111 (e.g., three protrusions) on the outer surface of the base component 110 mates with the anti-rotation feature 121 (e.g., three recesses) on the inner surface of the coping 120 such that the non-circular contour of the base component 110 aligns with the non-circular contour of the coping 120. In other words, the relative positions between the anti-rotation feature and the non-circular contour of the base component, and between the anti-rotation feature and the non-circular contour of the coping 120 are defined such that when the anti-rotation feature 111 of the base component 110 mates with the anti-rotation feature 121 of the coping 120, their respective non-circular contours align.

[0039] FIG. 5 illustrates an exemplary replica 130 configured to replicate the position and orientation of a base component (e.g., the base component 110 shown in FIG. 2). The replica 130 has a first anti-rotation feature 131 that can correspond to an anti-rotation feature of the base component (e.g., the anti-rotation feature 111 of the base component 110 shown in FIG. 2). The anti-rotation feature 131 of the replica 130 shown in FIG. 5 and the anti-rotation feature 111 of the base component 110 shown in FIG. 2 are both in the shape of three protrusions, even though there may be differences in the exact shapes. For example, although the outlines appear to be the same, the first anti-rotation feature 131 of the replica 130 may include a recessed portion in the center of the protrusion. As shown in FIG. 5, the replica 130 may also have a second anti-rotation feature 132. The second anti-rotation feature 132 may extend from the first anti-rotation feature 131 and may differ in shape and / or size from the first anti-rotation feature 131. FIG. 6 illustrates an exemplary upper component 140 (e.g., an abutment) having anti-rotation features 142 (e.g., three indentations) that can mate with a replica's second anti-rotation feature (e.g., replica 130 second anti-rotation feature 132 shown in FIG. 5). FIG. 7 illustrates an exemplary system 100 that can include one of the following components: an exemplary replica 130 and / or an exemplary upper component 140. FIG. 7 illustrates a cross-section of replica 130 shown in FIG. 5 coupled with upper component 140 shown in FIG. 6. In FIG. 7, anti-rotation features 142 (e.g., three indentations) on the inner surface of upper component 140 mate with second anti-rotation features 132 (e.g., three protrusions) on the outer surface of replica 130 such that the non-circular contour of the upper component aligns with the non-circular contour of replica 130.

[0040] In other words, the relative position between the anti-rotation feature of the upper component 140 and the non-circular outline and the relative position between the second anti-rotation feature of the replica 120 and the non-circular outline are defined such that when the anti-rotation feature 142 of the upper component 140 mates with the second anti-rotation feature 132 of the replica 130, their respective non-circular outlines are aligned.

[0041] 8 shows another cross section of the exemplary replica 130 shown in FIG. 5 coupled with the exemplary upper component 140 shown in FIG. 6. However, the first anti-rotation feature 131 (e.g., three protrusions) on the outer surface of the replica 130 does not mate with the inner surface of the upper component 140 (e.g., feature 141). In some cases, the feature 141 (e.g., three recesses) of the upper component 140 can have a larger size (e.g., compared to the first anti-rotation feature 131 of the replica 130), or the first anti-rotation feature 131 of the replica 130 can have a smaller size compared to feature 141. Because the first anti-rotation feature 131 of the replica (which can correspond to the anti-rotation feature 111 of the base component 110) does not mate with the upper component 140, the anti-rotation feature 111 of the base component 110 also does not mate with the upper component 140. Figure 9 illustrates a cross-section of the exemplary base component 110 shown in Figure 2 mated with the exemplary upper component 140 shown in Figure 6. The anti-rotation features 111 (e.g., three protrusions) on the outer surface of the base component 110 do not mate with the features 141 (e.g., three recesses) on the inner surface of the upper component 140.

[0042] FIG 10 shows another cross section of the example base component 110 shown in FIG 2 mated with the example upper component 140 shown in FIG 6. FIG 11 shows a longitudinal cross section of the example base component 110 shown in FIG 2 mated with the example upper component 140 shown in FIG 6. As shown in FIG 10 and 11, the anti-rotation feature 111 of the base component 110 does not reach the anti-rotation feature 142 of the upper component 140. FIG 11 also shows that the anti-rotation feature 111 on the outer surface of the base component 110 does not mate with the feature 141 on the inner surface of the upper component 140.

[0043] 12A-12D show other exemplary dental components and / or systems that may include any one or more of the components. FIG. 12A shows an exemplary base component 210 having anti-rotation features 211 (e.g., three protrusions). FIG. 12B shows an exemplary coping 220. The coping 220 may include anti-rotation features 221 (e.g., three recesses) configured to mate with the anti-rotation features 211 of the base component 210. In this example, the coping 220 also includes a cut-free 222 to avoid engagement with a second anti-rotation feature 232 of the replica. The coping 220 may also include orientation features 223 (e.g., protrusions and recesses). The orientation features 223 may provide orientation for the coping 220 such that the position and orientation of the base component 210 may be captured during mating.

[0044] FIG. 12C illustrates an exemplary replica 230 configured to replicate the position and orientation of the base component 210 illustrated in FIG. 12A. The replica 230 has a first anti-rotation feature 231 (e.g., three protrusions) that corresponds to the anti-rotation feature 211 of the base component 210. The replica 230 can also have a second anti-rotation feature 232 (e.g., three smaller protrusions or pins). In this example, the second anti-rotation feature 232 is located at the first anti-rotation feature 231. FIG. 12D illustrates an exemplary upper component 240. The upper component 240 has an anti-rotation 242 (e.g., three indentations) that cannot mate with the first anti-rotation feature 231 (e.g., feature / surface 241) of the replica 230, but can mate with the second anti-rotation feature 232.

FIG. 13A shows an exemplary base component 310 having anti-rotation features 311 (e.g., three protrusions). FIG. 13B shows an exemplary coping 320. The coping 320 may include anti-rotation features 321 (e.g., three recesses) configured to mate with the anti-rotation features 311 of the base component 310. The coping 320 may also include orientation features 323 (e.g., protrusions and recesses). FIG. 13C shows an exemplary replica 330 configured to replicate the position and orientation of the base component 310 shown in FIG. 13A. The replica 330 has a first anti-rotation feature 331 that corresponds to the anti-rotation feature 311 of the base component 310. The replica 330 may also have a second anti-rotation feature 332 (e.g., a smaller protrusion or pin). In this example, the second anti-rotation feature 332 is located on a surface configured to mate with an adjacent component (e.g., coping, abutment, prosthesis, etc.). The coping 320 of FIG. 13B does not include an additional anti-rotation feature to mate with the second anti-rotation feature 332 of the replica 330 shown in FIG. 13C. FIG. 13D illustrates an exemplary upper component 340. The upper component 340 has an anti-rotation 342 (e.g., a recess) that can mate with the second anti-rotation feature 332 of the replica 330. The upper component 340 does not mate with the first anti-rotation feature 331 (e.g., feature / surface 341) of the replica 330.

[0046] 14A-14G show other exemplary dental components and / or systems 400 that may include any one or more of the components. FIG. 14A shows an exemplary base component 410 having anti-rotation features 411 (e.g., three protrusions). FIG. 14B shows an exemplary coping 420. The coping 420 may include anti-rotation features 421 (e.g., three recesses) configured to mate with the anti-rotation features 411 of the base component 410. The coping 420 may also include orientation features 423 (e.g., protrusions and recesses). FIG. 14C shows an exemplary replica 430 configured to replicate the position and orientation of the base component 410 shown in FIG. 14A. The replica 430 has a first anti-rotation feature 431 (e.g., three protrusions) that corresponds to the anti-rotation feature 411 of the base component 410. The replica 430 may also have a second anti-rotation feature 432. In this example, the second anti-rotation feature 432 is a grooved surface configured to mate with an adjacent component (e.g., a coping, abutment, prosthesis, etc.). The coping 420 of FIG. 14B does not include an additional anti-rotation feature to mate with the second anti-rotation feature 432 of the replica 430 shown in FIG. 14C. FIG. 14D shows an exemplary upper component 440. The upper component 440 has an anti-rotation 442 that cannot mate with the first anti-rotation feature 431 (e.g., feature / surface 441) of the replica 430, but can mate with the second anti-rotation feature 432.

[0047] FIG 14E shows the example replica 430 shown in FIG 14C mated with the example upper component 440 shown in FIG 14D. FIG 14F shows a cross section of the example replica 430 mated with the example upper component 440 shown in FIG 14E. FIG 14G shows another cross section of the example replica 430 mated with the example upper component 440 shown in FIG 14E. As shown in FIGS 14F and 14G, the second anti-rotation feature 432 of the replica 430 can be configured to mate with the anti-rotation feature 442 of the upper component 440. However, the upper component 440 (e.g., surface / feature 441) does not mate with the first anti-rotation feature 431 of the replica 430.
