Description

Background Art Technical Field

[0002] The present disclosure relates to dental components and methods of aligning dental components.

[0003] Prior art

[0004] A dental restoration system may include components such as dental implants, intermediate components such as abutments, and prostheses such as crowns or bridges. Impressions or scans of implant sites may be used to record information about implants in a patient's mouth to help manufacture the prostheses and / or intermediate components. In some cases, a coping (e.g., an impression coping or scan body) may be used in conjunction with a dental implant or intermediate component to help record the position and orientation of the implant or intermediate component in the patient's mouth.

[0005] For implants and / or abutments having non-circular interfaces or external shapes, it may be necessary to know the rotational position of the lower component so that the upper component can be registered (e.g., aligned) with the lower component. In other words, it is possible to align the non-circular interface or external shape of the upper component with the non-circular interface or external shape of the lower component. For some components, such as dental bridges, mating with the lower non-circular component may be complicated because non-engaging surfaces may also need to be provided that may allow for a certain "gap" between the dental bridge and the lower component. Summary of the invention

[0006] Various 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 an underlying component (e.g., an intermediate component or an implant) but can still be oriented and aligned with the underlying component.

[0007] In certain embodiments, a system may be configured to record a position and orientation of a dental component. The system may include a top cover and a replica. The top cover may include an anti-rotation feature configured to cooperate with an anti-rotation feature of a dental component. The top cover may also include an orientation feature configured to communicate the orientation of the dental component. The replica may include a first anti-rotation feature corresponding to the anti-rotation feature of the dental component. The replica may also include a second anti-rotation feature that does not correspond to the anti-rotation feature of the dental component.

[0008] In some cases, the cap can include an impression cap configured to be embedded in an impression medium to record the position and orientation of the dental component. In some cases, the cap can include a scan volume configured to be scanned to record the position and orientation of the dental component.

[0009] In various embodiments, the top cover may include an outer surface having an orientation feature. The top cover may also include an inner surface having an anti-rotation feature. In some cases, the orientation feature and / or the anti-rotation feature of the top cover may include a protrusion, a recess, a pin or a groove.

[0010] In some cases, the second anti-rotation feature of the replica can be positioned on the first anti-rotation feature of the replica. In some cases, the second anti-rotation feature of the replica can be positioned on a surface configured to mate with an adjacent component. The adjacent component can include a cap, 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.

[0011] 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 a dental implant.

[0012] In various embodiments, the system can be configured to align a dental component with another dental component. The dental component can have a non-circular external cross-sectional interface. For example, the non-circular external cross-sectional interface can include a triangular elliptical or quadrangular elliptical interface. In some embodiments, the system can also include another dental component. The other dental component can be configured to cooperate 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.

[0013] In certain embodiments, a method of manufacturing a second dental component configured to align with a first dental component in a patient's mouth may be provided. The method may include mating a replica with a coping. The coping may have an orientation feature that has been recorded relative to the first dental component to communicate the position and orientation of the first dental component in the patient's mouth. The replica may include a first anti-rotation feature that corresponds to the anti-rotation feature of the first dental component. The replica may also include a second anti-rotation feature that does not correspond to the anti-rotation feature of the first dental component. The method may also include forming a model of at least a portion of the patient's mouth adjacent to the replica mated with the coping. The method may also include unmating the coping from the replica. The method may also 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.

[0014] In various embodiments, the method can further include engaging the top cap with the first dental component. The top cap can include an anti-rotation feature configured to engage with an anti-rotation feature of the first dental component. The method can further include recording an orientation feature of the top cap engaged with the first dental component to record a position and orientation of the first dental component. The method can further include separating the top cap from the first dental component.

[0015] 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.

[0016] In some methods, the first dental component and the second dental component can have a non-circular external cross-sectional interface. For example, the non-circular external cross-sectional interface can include a triangular elliptical or quadrangular elliptical interface.

[0017] In some cases, the first dental component can be a dental implant or an adapter configured to mate with a dental implant.

[0018] In some embodiments, creating the second dental component can include creating an abutment and / or a prosthesis.

[0019] In certain embodiments, the replica can be configured to transfer the orientation of the first dental component to the second dental component. The replica can include an outer surface having a first anti-rotation feature and a second anti-rotation feature. In some embodiments, the first anti-rotation feature corresponds to the anti-rotation feature of the first dental component, and the second anti-rotation feature does not correspond to the anti-rotation feature of the first dental component.

[0020] In some embodiments, the replica can be configured to cooperate with the anti-rotation feature of the coping to replicate the position and orientation of the first dental component.

[0021] In some cases, the replica may be configured to mate with the second dental component via the second anti-rotation feature of the replica but not via the first anti-rotation feature of the replica.

[0022] In some cases, the first anti-rotation feature and / or the second anti-rotation feature of the replica may include a protrusion, a recess, a pin, or a groove.

[0023] In certain embodiments, the multi-unit prosthesis can be configured to align with the dental component. The multi-unit prosthesis can include an anti-rotation feature. In some cases, the anti-rotation feature can be configured to mate with an anti-rotation feature of a replica of the dental component. In some cases, the anti-rotation feature of the prosthesis can be configured not to mate with the anti-rotation feature of the dental component. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 1 is a schematic diagram of an exemplary dental component and an exemplary workflow. One or more of the dental components may provide a system and / or method for aligning dental components. One of the components may be a lower component, such as a component implanted in a patient's mouth. As an example, the lower 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 to be coupled (directly or indirectly) to the lower 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 a non-circular external cross-sectional interface (e.g., a triangular elliptical interface, a quadrangular elliptical interface, etc.) and / or a multi-unit prosthesis (e.g., a dental bridge) that also has a non-circular external cross-sectional interface.

[0051] As an overview, the system 1 (and / or workflow) may include any one or more of the following components: a lower component 10, a top cover 20, a replica 30, and / or an upper component 40. The system 1 may include any one, two, three, or all four components, alone or in combination with other components. In some cases, the system 1 may be configured to record the position and orientation of the lower component 10. The lower component 10 may have an anti-rotation feature 11. In some embodiments, the system 1 may include a top cover 20. The top cover 20 may include an anti-rotation feature 21 configured to cooperate with the anti-rotation feature 11 of the lower component 10. The top cover 20 may also include an orientation feature 23 configured to communicate the orientation of the lower component 10. In some embodiments, the system 1 may include a replica 30 (e.g., configured to replicate the position and orientation of the lower component 10). The replica 30 may 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 lower component 10, while the second anti-rotation feature 32 does not correspond to the anti-rotation feature 11 of the lower component 10. Thus, the first anti-rotation feature 31 of the replica 30, but not the second anti-rotation feature 32, may be configured to cooperate with the anti-rotation feature 21 of the top cover 20. 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 cooperate with the second anti-rotation feature 32 of the replica 30, but not with the first anti-rotation feature 31 of the replica 30. In use, the orientation of the lower component 10 may be transmitted to the replica 30 via the anti-rotation feature 21 of the top cover 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 lower component 10. However, since the upper component 40 does not cooperate with the first anti-rotation feature 31 of the replica 30, the upper component 40 also does not cooperate with the first anti-rotation feature 11 of the lower component 10. Thus, a "gap" may also be provided between the lower component 10 and the upper component 40.

[0052] Each component will now be described in more detail.

[0053] In some embodiments, the system 1 may include a lower component 10. The lower component 10 may be a component that is at least partially implanted below the gum line in the patient's mouth. Therefore, the lower component 10 is not limited to a component coupled to the patient's lower jaw, but may be coupled to the patient's upper jaw. In some embodiments, the lower component 10 may be a dental implant or an intermediate component (e.g., an adapter or abutment) configured to cooperate with the dental implant (e.g., directly or indirectly). The lower component 10 may have an anti-rotation feature 11, which is, for example, configured to cooperate with another component (e.g., engage or shift) to reduce and / or prevent rotational movement between components. The anti-rotation feature 11 is not particularly limited in quantity. For example, the anti-rotation feature 11 of the lower component 10 may have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. anti-rotation features, or may have a series of anti-rotation features formed by these values ​​(e.g., from 1 to 10 features, etc.).

[0054] exist Figure 1 , the anti-rotation feature 11 is disposed on the outer surface of the lower component 10. However, the anti-rotation feature 11 may be disposed on the inner surface of the lower component 10. In some cases, the anti-rotation feature 11 may be disposed on both the outer surface and the inner surface of the lower component 10. The anti-rotation feature 11 is also not particularly limited in shape and size. In the case where an anti-rotation feature 11 includes more than one anti-rotation feature, 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, etc. In Figure 1 In the example shown in , the anti-rotation feature 11 of the lower assembly 10 includes two anti-rotation features (eg, two protrusions) that can cooperate with the top cover 20 .

[0055] In some embodiments, the system 1 may include a top cover 20. Figure 1 , the top cover 20 has an anti-rotation feature 21 configured to cooperate with the anti-rotation feature 11 of the lower component 10. By cooperating with the anti-rotation feature 11 of the lower component 10, the top cover 20 can communicate (and / or transfer) the position and orientation of the lower component 10 to another component (e.g., via the anti-rotation feature 21). The anti-rotation feature 21 of the top cover 20 can be complementary to the anti-rotation feature 11 of the lower component. Figure 1In the example shown in , the anti-rotation feature 21 (e.g., two recesses) of the top cover 20 can cooperate with the anti-rotation feature 11 (e.g., two protrusions) of the lower component 10. Since the anti-rotation feature 21 of the top cover 20 can be complementary to the anti-rotation feature 11 of the lower component 10, similar to the lower component 10, the anti-rotation feature 21 of the top cover 20 is not particularly limited in number. For example, the anti-rotation feature 21 of the top cover 20 may include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. anti-rotation features, or may have a series of anti-rotation features formed by these values ​​(e.g., from 1 to 10 features, etc.).

[0056] The anti-rotation feature 21 may be disposed on the inner surface of the top cover 20 (e.g., if the anti-rotation feature 11 of the lower component 10 is on the outer surface of the lower component 10), on the outer surface of the top cover 20 (e.g., if the anti-rotation feature 11 of the lower component 10 is on the inner surface of the lower component 10), or on both the inner and outer surfaces of the top cover 20 (e.g., if the anti-rotation feature 11 of the lower component 10 is on both the outer and inner surfaces of the lower component 10). Figure 1 , the anti-rotation feature 21 of the top cover 20 is disposed on the inner surface (e.g., to cooperate with the anti-rotation feature 11 on the outer surface of the lower component 10). The anti-rotation feature 21 is also not particularly limited in shape and size. In the case where the anti-rotation feature 21 includes more than one anti-rotation feature, 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 21 may include a protrusion, a recess, a pin, a groove, a snap-fit ​​feature, etc. As described herein, the top cover 20 may communicate the position and orientation of the lower component 10 by cooperating with the anti-rotation feature 11 of the lower component 10 (e.g., via the anti-rotation feature 21).

[0057] The top cover 20 may also include an orientation feature 23. The orientation feature 23 may be configured to provide orientation of the top cover 20 so that the position and orientation of the lower component 10 can be captured, for example, in a recording medium. In some cases, the top cover 20 may include a stamp top cover. The stamp top cover may be configured to be embedded in the stamp medium (in Figure 1 In step 1B, the top cover 20 is schematically represented by the reference numeral 25 to record the position and orientation of the lower component 10. The stamp top cover can be a transfer type or a pick-up type top cover. The stamp medium can be any of the stamp media known in the art or to be developed. For example, the stamp medium may include a curable resin. In some cases, the top cover 20 may include a scanning body. The scanning body may be configured to be scanned to record the position and orientation of the lower component 10. The scanning body can be scanned using any technology known in the art or to be developed. For example, the scanning body can be optically scanned. As another example, the scanning body can be mechanically scanned.

[0058] Orientation feature 23 may include a protrusion, a recess, a pin, a groove, etc. In some cases, orientation feature 23 may include an edge of top cover 20. For example, in Figure 1 In the example shown in , the top cover 20 has an orientation feature 23 including an edge of the outer surface. In some cases where the lower component 10 has a non-circular (e.g., non-circular) external cross-sectional interface, the orientation feature can be an external cross-sectional shape, such as a triangular elliptical interface, a quadrangular elliptical interface, etc. In various embodiments, the top cover 20 may have an outer surface including the orientation feature 23. In various embodiments, the top cover 20 may have an inner surface including the orientation feature 23. In some cases, the orientation feature 23 of the top cover 20 may be set on both the outer surface and the inner surface. As described herein, the top cover 20 can communicate the position and orientation of the lower component 10 in the recording medium and / or to another component, such as a replica 30.

[0059] Continue to refer Figure 1 , the system 1 may include a replica 30. The replica 30 may be configured to replicate the position and orientation of the lower component 10 and / or transfer the orientation of the lower 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 lower component 10. Therefore, the first anti-rotation feature 31 of the replica 30 may be configured to cooperate with the anti-rotation feature 21 of the top cover 20 to replicate the position and orientation of the lower component 10 in the top cover 20. Since the first anti-rotation feature 31 of the replica 30 may correspond to the anti-rotation feature 11 of the lower component 10, the first anti-rotation feature 31 is not particularly limited in number, shape and / or size. Also similar to the anti-rotation feature 11 of the lower component 10, the first anti-rotation feature 31 of the replica 30 may be disposed on the outer surface, the inner surface, or both the outer surface and the inner surface of the replica 30. The first anti-rotation feature 31 may include a protrusion, a recess, a pin, a groove, a snap-fit ​​feature, etc.

[0060] The replica 30 may further include a second anti-rotation feature 32. The second anti-rotation feature 32 is not particularly limited in number, shape, and / or size. Likewise, the second anti-rotation feature 32 of the replica 30 may be disposed 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, etc. Figure 1 In the embodiment, the second anti-rotation feature 32 of the replica 30 does not correspond to the anti-rotation feature 11 of the lower component 10, and therefore does not cooperate with the anti-rotation feature 21 of the top cover 20. Figure 1, the second anti-rotation feature 32 of the replica 30 can extend from the first anti-rotation feature 31. In some cases, the second anti-rotation feature 32 can be positioned on the first anti-rotation feature 31. In some cases, the second anti-rotation feature 32 can be positioned separately from the first anti-rotation feature 31. For example, the second anti-rotation feature 32 can be positioned on a surface configured to mate with an adjacent component (e.g., with the top cover 20, the upper component 40, etc.).

[0061] The replica 30 can transfer the orientation of the lower component 10 to the upper component 40 by cooperating with the anti-rotation feature 21 of the top cover 20 (e.g., via the first anti-rotation feature 31) and cooperating with the upper component 40 (e.g., via the second anti-rotation feature 32). Therefore, the upper component 40 can be aligned with the lower component 10. In other words, if the upper component 40 and the lower component 10 each have a non-circular (e.g., non-circular) external cross-sectional interface, the two non-circular (e.g., non-circular) external cross-sectional interfaces can be aligned. For some upper components 40, such as multi-unit prostheses such as dental bridges, it may be necessary to provide non-engaging surfaces that can allow a certain "gap" between the upper component 40 and the lower component 10. For some such cases, as will be described with respect to the upper component 40, the first anti-rotation feature 31 of the replica 30 (which corresponds to the anti-rotation feature 11 of the lower component 10) can be configured not to cooperate with the upper component 40.

[0062] For example, continue to refer to Figure 1 , the upper component 40 can be a component configured to be coupled to the lower component 10 and implanted above the gum line in the patient's mouth. Therefore, the upper component 40 can be a component coupled to the patient's lower jaw or upper jaw. In some embodiments, the upper component 40 can be an abutment and / or a prosthesis (e.g., a single or multi-unit prosthesis).

[0063] By directional transfer between components, the upper component 40 can be configured to align with the lower component 10. For example, the first anti-rotation feature 31 of the replica 30 can correspond to the anti-rotation feature 11 of the lower component 10, and the upper component 40 can be configured to cooperate with the second anti-rotation feature 32 of the replica 30. In some cases, the lower component 10 and the upper component 40 can have a non-circular external cross-sectional interface, for example, a triangular elliptical interface, a quadrangular elliptical interface, etc. In some cases (for example, where the upper component 40 is an intermediate component such as an abutment), a prosthesis can be manufactured to couple with the upper component 40 so that the prosthesis can be aligned with the lower component 10. As described herein, the upper component 40 can be a multi-unit (or multi-tooth) prosthesis (for example, a dental bridge), or can be one or more abutments that can be coupled to a multi-unit prosthesis. In some such cases, the multi-unit prosthesis can include an anti-rotation feature 42. The anti-rotation feature 42 can be configured to cooperate with the second anti-rotation feature 32 of the replica 30. On the other hand, the anti-rotation feature 42 can be configured to not cooperate with the first anti-rotation feature 31 of the replica 30 corresponding to the anti-rotation feature 11 of the underlying component 10. Thus, the multi-unit prosthesis can be configured to contact the underlying component 10 but allow a "gap" between the multi-unit prosthesis and the underlying component 10, at least about one axis.

[0064] As an example of workflow, the lower assembly 10 may be placed in the patient's mouth. A cap 20 (eg, an impression cap or scan body) may be positioned with the lower assembly 10 (see Figure 1 , at step 1A). In some cases, the anti-rotation feature 21 of the top cover 20 may mate with the anti-rotation feature 11 of the lower component 10. The orientation feature 23 of the top cover 20 that mates with the lower component 10 may be recorded to record the position and orientation of the lower component 10 relative to its environment (i.e., adjacent teeth and soft tissue). The top cover 20 may be separated from the lower component 10. The replica 30 may be engaged with the top cover 20 (e.g., with a recording medium, see 1, at step 1B). The orientation feature 23 may be recorded relative to the lower component 10 to convey the position and orientation of the lower component 10 in the patient's mouth. A model 55 of the patient's mouth adjacent to at least a portion of the replica 30 that mates with the top cover 20 may be formed. The top cover 20 (e.g., with the recording medium 25) may be separated from the replica 30, thereby leaving the replica 30 in the model (see Figure 1 , at step 1C). The upper component 40 (eg, abutment and / or prosthesis) may be created so that the upper component 40 may cooperate with the second anti-rotation feature 32 of the replica 30 instead of the first anti-rotation feature 31 (see Figure 1, at step 1C). In this example, since the first anti-rotation feature 31 of the replica 30 may correspond to the anti-rotation feature 11 of the lower component 10, the upper component 40 also does not cooperate with the anti-rotation feature 11 of the lower component 10. Although the upper component 40 can cooperate with the second anti-rotation feature 32 of the replica 30, since the lower component 10 does not have a feature corresponding to the second anti-rotation feature 32, the upper component 40 can be configured not to cooperate with the lower component 10. After the upper component 40 is manufactured, it can be separated from the replica 30 and placed on the lower component 10, aligned but not engaged (see Figure 1 , at step 1D).

Figure 2 An exemplary lower level component 110 is shown having anti-rotation features 111 (eg, three protrusions). The lower level component 110 has a non-circular outer shape. Figure 3 An exemplary cap 120 is shown having an anti-rotation feature 121 (eg, three recesses) that may be used with Figure 2 The exemplary top cover 120 further includes an orientation feature 123 disposed on a side opposite to the anti-rotation feature 121. The orientation feature 123 may be in the form of a non-circular outer shape. Figure 4 An exemplary system 100 is shown, which may include one of the following components: an exemplary lower level component 110 and / or an exemplary top cover 120 . Figure 4 Shown with Figure 3 The top cover 120 shown in FIG. Figure 2 A cross section of the lower assembly 110 is shown in FIG. Figure 4 , the anti-rotation feature 111 (e.g., three protrusions) on the outer surface of the lower component 110 cooperates with the anti-rotation feature 121 (e.g., three recesses) on the inner surface of the top cover 120 so that the non-circular outer shape of the lower component 110 is aligned with the non-circular outer shape of the top cover 120. In other words, the relative position between the anti-rotation feature and the non-circular outer shape of the lower component and the relative position between the anti-rotation feature and the non-circular outer shape of the top cover 120 are defined so that when the anti-rotation feature 111 of the lower component 110 cooperates with the anti-rotation feature 121 of the top cover 120, their respective non-circular outer shapes are aligned.

[0066] Figure 5 An exemplary replica 130 is shown, which is configured to replicate an underlying component (e.g., Figure 2The replica 130 has a first anti-rotation feature 131, which may correspond to the anti-rotation feature of the lower component (e.g., Figure 2 10). The anti-rotation feature 111 of the lower component 110 is shown in FIG. Figure 5 The anti-rotation feature 131 and Figure 2 The anti-rotation features 111 of the lower component 110 shown in FIG. 1 are all in the shape of three protrusions, although the exact shape may be different. For example, the external shape may look similar, while the first anti-rotation feature 131 of the replica 130 may include a recessed portion located in the center of the protrusion. Figure 5 As shown in FIG. 1 , 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 be different from the first anti-rotation feature 131 in shape and / or size. Figure 6 An exemplary upper component 140 (eg, a base) is shown having an anti-rotation feature 142 (eg, three recesses) that can be coupled to a second anti-rotation feature of a replica (eg, Figure 5 The second anti-rotation feature 132 of the replica 130 shown in FIG. Figure 7 An exemplary system 100 is shown, which may include one of the following components: an exemplary replica 130 and / or an exemplary upper component 140 . Figure 7 Shown with Figure 6 The upper assembly 140 shown in FIG. Figure 5 A cross section of a replica 130 is shown in FIG. Figure 7 In the embodiment, the anti-rotation features 142 (e.g., three recesses) on the inner surface of the upper component 140 cooperate with the second anti-rotation features 132 (e.g., three protrusions) on the outer surface of the replica 130 so that the non-circular outer shape of the upper component is aligned with the non-circular outer shape of the replica 130.

[0067] In other words, the relative position between the anti-rotation feature and the non-circular outer shape of the upper component 140 and the relative position between the second anti-rotation feature and the non-circular outer shape of the replica 120 are defined so that when the anti-rotation feature 142 of the upper component 140 is mated with the second anti-rotation feature 132 of the replica 130, their respective non-circular outer shapes are aligned.

[0068] Figure 8 Shown with Figure 6 The exemplary upper assembly 140 shown in FIG. Figure 5140 . 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 (e.g., feature 141) of the upper component 140. In some cases, the feature 141 (e.g., three recesses) of the upper component 140 may 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 may have a smaller size than the feature 141. Since the first anti-rotation feature 131 of the replica (which may correspond to the anti-rotation feature 111 of the lower component 110) does not mate with the upper component 140, the anti-rotation feature 111 of the lower component 110 does not mate with the upper component 140 either.
