    Description

    FIELD OF THE INVENTION



    [0001] The present invention relates generally to an abutment system for a dental implant system. More particularly, the present invention relates to a dental implant having an upper surface that is coded to provide details about the dental implant.

    BACKGROUND OF THE INVENTION



    [0002] The dental restoration of a partially or wholly edentulous patient with artificial dentition is typically done in two stages. In the first stage, an incision is made through the gingiva to expose the underlying bone. An artificial tooth root, in the form of a dental implant, is placed in the jawbone for osseointegration. The dental implant generally includes a threaded bore to receive a retaining screw for holding mating components thereon. During the first stage, the gum tissue overlying the implant is sutured and heals as the osseointegration process continues.

    [0003] Once the osseointegration process is complete, the second stage is initiated. Here, the gingival tissue is re-opened to expose an end of the dental implant. A healing component or healing abutment is fastened to the exposed end of the dental implant to allow the gingival tissue to heal therearound. It should be noted that the healing abutment can be placed on the dental implant immediately after the implant has been installed and before osseointegration. In some situations, the osseointegration step and gingival healing steps have been combined into a one-step process. Alternatively, instead of a healing abutment, a temporary abutment may be used to support a temporary prosthesis and also serves the purpose of shaping the gingiva above the dental implant, just like a healing abutment.

    [0004] In more recent years, scanning technologies have been used to aid in the development of permanent prostheses. The scanning technologies are used to locate the underlying dental implant to which the final prosthesis is supported, as well as the adjacent soft tissue, the adjacent dentition, and the opposing dentition. The present disclosure is directed to a coding system on the dental implant that provides information that can be acquired via an intra-oral scan to gain information about the underlying implant. US2004/0191727 discloses an implant having a body for inserting into the bone, having indicia used to facilitate the orienting of the implant so that the distal and mesial sides assume desired orientations in the patient's jaw bone.

    SUMMARY OF THE INVENTION



    [0005] The invention relates to a dental implant according to claim 1. Advantageous features of the invention are defined in the dependent claims. Described is a dental implant for insertion into bone within a patient's mouth comprises an implant body and a scannable code. The body includes a bone-engaging exterior surface, an anti-rotational feature for non-rotationally mating with an abutment, and an upper region. The upper region includes an upper surface for engaging the abutment. The scannable code on the upper surface provides information concerning an angular orientation of the anti-rotational feature and a size dimension of the dental implant.

    [0006] Also described is a dental implant for insertion into bone within a patient's mouth, comprising an implant body and a scannable code. The body includes a bone-engaging exterior surface, an anti-rotational feature for non-rotationally mating with an abutment, and an upper region. The upper region includes an upper surface for engaging the abutment. The scannable code on the upper surface provides information concerning the dental implant. The information including at least two features of the dental implant

    [0007] Further described is a method of using a dental implant that has been placed in bone within the mouth of a patient. The method comprises (i) scanning the mouth including an upper surface of the dental implant so as to acquire scan data corresponding to a scannable code on the upper surface, (ii) developing a virtual model of at least a portion of the mouth of the patient, and (iii) using the scan data to locate a virtual implant within the virtual model.

    DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS



    [0011] Referring to FIGS. 1 and 2, a dental implant 10 includes a bore 12 with an anti-rotational section 14 and a threaded section 16. The anti-rotational section 14 is shown as a hexagonal socket, although several other types of anti-rotational features (both internal and external) can be used on the dental implant 10. The upper portion of the dental implant 10 includes a table 20, which is an upper surface (e.g., the uppermost surface for dental implants with an internal connection) that engages an abutment that is mated with the dental implant 10. The abutment would be held on the dental implant 10 via a screw that engages the threaded section 16 of the dental implant 10.

    [0012] FIGS. 3A-3C illustrate a scannable code on the upper surface 20 of the dental implant 10. The scannable code is a radially extending marker 22 that is used to provide information related to the dental implant 10. The radially extending marker 22 can also be of different lengths to provide additional information. For example, the radially extending marker 22a having a first length (FIG. 3A) can be indicative of a first feature of the dental implant, the radially extending marker 22b having a second length (FIG. 3B) can be indicative of a second feature of the dental implant, and the radially extending marker 22c having a third length (FIG. 3C) can be indicative of a third feature of the dental implant. For example, each of the markers 22a, 22b, 22c can indicate the location of one flat of the anti-rotational section 14 so that the implant's angular orientation and, hence, the angular orientation of the anti-rotational section 14 is known. The length of the radially extending markers 22a, 22b, and 22c may indicate a dimension of the implant, such as its length or diameter of the upper surface 20. In short, the radially extending markers 22a, 22b, and 22c are codes that are indicative of one or more features of the dental implant 10.

    [0013] FIGS. 4A-4C illustrate a second type of scannable code on the upper surface 20 of the dental implant 10. The scannable code is a circumferentially extending marker 24 that is used to provide information related to the dental implant 10. The circumferentially extending marker 24 can also be of different lengths to provide additional information. For example, the circumferentially extending marker 24a having a first length (360 degrees in FIG. 4A) can be indicative of a first feature of the dental implant, the circumferentially extending marker 24b having a second length (90 degrees in FIG. 4B) can be indicative of a second feature of the dental implant, and the circumferentially extending marker 24c having a third length (180 degrees in FIG. 4C) can be indicative of a third feature of the dental implant. Of course, the circumferential length can be broken down in terms of 30-degree segments or 60-degree segments, as opposed to the 90-degree segments suggested by FIGS. 4A-4C. The length of the circumferentially extending markers 24a, 24b, and 24c may indicate a dimension of the implant, such as its length or diameter of the upper surface 20. The circumferentially extending markers 24a, 24b, and 24c can also be used to identify the central axis of the implant 10 because each would have a radius of curvature that is centered around the central axis. Hence, the circumferentially extending markers 24a, 24b, and 24c help define the coordinate system used for the prosthetic restoration. In short, the circumferentially extending markers 24a, 24b, and 24c are codes that are indicative of one or more features of the dental implant 10.

    [0014] FIGS. 5A-5B illustrate the use of a combination of the radially extending markers 22 on FIG. 3 and the circumferentially extending markers 24 of FIG. 4 that are used to provide information related to the dental implant 10. The circumferentially extending markers 24 may indicate a first dimension of the implant, such as its diameter, while the radially extending markers 22 can be indicative of a second dimension of the implant, such as its length. Additionally, each of the radially extending markers 22 can indicate the location of one flat of the anti-rotational section 14 so the implant's angular orientation and, hence, the angular orientation of the anti-rotational section 14 is known. In short, the combination of the circumferentially extending markers 24 and radially extending markers 22 present a code that is indicative of one or more features of the dental implant 10.

    [0015] The circumferentially extending markers 24 and radially extending markers 22 can be placed on the upper surface in several ways. For example, they can be etched or printed (e.g. laser etching or laser printing) on the upper surface 20 or they may developed by a micro-grooving process.

    [0016] Of course, other types and shapes of information markers are possible on the upper surface 20 of the dental implant 10. For example, FIG. 6 illustrates the use of a bar-code marker 26 that can provide several detailed pieces of information once the scanning system has read the code on the bar-code marker 26. The information markers could include discrete scannable symbols, such as a "+" symbol, a "-" symbol, a "o" symbol, and a "Δ" symbol (etched or printed on the upper surface). Additionally, the presence or absence of each discrete symbol can be thought of as "1" or a "0" in a certain location on the upper surface 20, such that the orientations markers present, as a group, a code that is akin to a binary code of 1's and 0's. The unique code for each implant would be used to identify it. Any of these codes can be used in conjunction with or in combination with the markers 22 and 24 of FIGS. 3-5.

    [0017] In addition to the aforementioned information regarding the implants, the codes can also provide the location of the table 20 (the uppermost surface) of the implant 10, the type of implant (e.g. its type of internal connection), the type of implant including its bone-interfacing surface technology (e.g., acid-etched, grit-blasted, nano-etched, nanoparticles, etc.), the basic catalog information, and the implant manufacturer's identity. Additionally, various markers or symbols (e.g., an arrow marker or diamond marker) can be added to the upper surface to identify one of the flat surfaces of the anti-rotation feature 14. Also, the scannable code can be used to indicate if the implant 10 is of a type that is normally platform-switched (e.g., an implant 10 that has a slight bevel at its periphery on the upper surface 20, where the abutment does not engage the bevel and may be diametrically smaller than the max diameter of the upper surface 20).

    [0018] Other types of coded systems could be used instead of the system that is discussed with reference to FIGS. 3-6. For example, the same symbol at different locations on the surface of the upper surface 20 could identify the unique implant 10. For example, the upper surface 20 of the implant 10 can be segmented into twelve regions, wherein each 30° segment has a geometrical pie shape, like hour segments on a clock. A single orientation line is present at one angular location, e.g., at 12 o'clock, and is used for locating the anti-rotational surface of the underlying implant 120 as well as setting the circumferential order of the twelve segments. A single type of information marker (e.g., a "Δ" symbol) can be placed at one of the twelve segments on the top surface, with each of the twelve segments corresponding to one of twelve possible implants 10 having a known size (length and diameter). Of course, the discrete locations can be more or less than twelve, depending on the number that is needed. And, the discrete locations may include different radially spaced locations, and not just circumferentially spaced locations. Yet further, a combination of discrete locations and specific types of symbols can increase the potential number of options (i.e., a "+" symbol at circumferential segment #1 of 12 is implant "A", but a "Δ" symbol at circumferential segment #1 of 12 is implant "B"). Accordingly, the location of a single type (or multiple types) of information marker within one of several distinct locations on the upper surface 20 provides a coded system to identify the underlying implant 10, and the scanning process can easily identify the information marker and its location.

    [0019] In addition to the unique codes being defined by symbols or markings, the codes for defining the dimensions of the healing cap 24 can be presented in the form of different colors (or combinations thereof) that define one or more features of the dental implant. Because the resolution and the photo-realistic data capture of the current intra-oral scanning systems and method has improved, these colors markers can be readily identified, such that the identification of implant 10 can be achieved. Accordingly, intra-oral scanning of the implant 10 may capture scan data corresponding to a unique combination of color(s), symbol(s), and/or other markings from the implant that serves as a code (or part of a code) for identifying the particular implant 10.

    [0020] Further, because the data acquisition capabilities of current intra-oral scanning systems and methods has improved, the upper surface of the implant 10 can be scanned and shape-matched to help identify the implant to its diametric dimension. In other words, the actual diametric size of the upper surface 20 serves as part of the information that is used to identify the implant 10. The location of any information marker on the upper surface 20 relative to the scanned circumference of the upper surface 20 provides an informational combination that can be matched against library of implants to identify the specific implant 10 that has been scanned. The markers (e.g., a "Δ" symbol or a "o" symbol or a circumferentially extending markers) can have the same size on all diametric sizes of the implants, such that the relative dimensions of the information marker to each implant's diameter is different, which assists with the shape-matching algorithm.

    [0021] Alternatively, the scanning can rely on less than the entire upper surface 20 of the implant, such as when the gingiva begins to grow slightly over the implant 10. Hence, the markers may all reside within a radial distance that is less than 90%, 80%, or 75% of the overall diameter so that their ability to be viewed (i.e., scanned) within the scanning process is unimpeded.

    [0022] In one method, after the dental implant 10 has been installed, a clinician may immediately scan the mouth and dental implant 10. Or, the implant 10 and mouth may be scanned to identify the conditions in the patient's mouth after the gingival tissue has healed around a healing abutment or temporary prosthesis. In this situation, the healing abutment or temporary prosthesis is removed prior to the scanning process, which reveals the subgingival contour leading down to the implant's upper surface 20. The scan data achieved in the scanning process includes the adjacent gingival tissue and, possibly, teeth. The scan data is used to develop a virtual model, which is typically displayed on a computer display. The scan data corresponding to the scannable code on the implant 10 is used to identify the type of dental implant and place a virtual implant at the correct position in the virtual model. The virtual implant may only need to be a portion of the actual implant, such as its upper surface and its anti-rotational feature. The virtual model is used to develop a patient-specific custom abutment and, possible an overall prosthesis that includes the abutment. In summary, a patient-specific custom abutment (and an overall prosthesis, which may include a patient-specific custom abutment) can be developed based on the information derived from the scannable code that produces (i) geometric and locational information for the implant 10 relative to the adjacent soft tissue structures and teeth (or a tooth) and (ii) the angular orientation of the implant's anti-rotational feature 14. Again, the intra-oral scanning may take place before, during, or after the gingival-healing period. Stated differently, the scannable code on the implant 10 provides information related to the prosthetic restoration's interface coordinate system, the seating diameter of the implant 10, the type of connection to the prosthesis, and the orientation of the anti-rotational connection -- all of which are helpful in the virtual design process that is used in making a patient-specific custom abutment and the overall prosthesis.

    [0023] While the illustrated embodiments have been primarily described with reference to the development of a patient-specific abutment for a single tooth application, it should be understood that the present invention is also useful in multiple-tooth applications, such as bridges and bars for supporting full or partial dentures. In those situations, the patient-specific abutment would not necessarily need a non-rotational feature for engaging the underlying implant(s) because the final prosthesis would also be supported by another structure in the mouth (e.g., one or more additional underlying implants), which would inherently achieve a non-rotational aspect to the design. In any event, using a scanning process to obtain the necessary information about the emergence profile shape of the gingiva and the dimensional and/or positional information for the implant(s) (via information markers in the temporary prosthetic assembly) can lead to the development of an aesthetically pleasing multiple-tooth system.

    [0024] While the present invention has been described with reference to one or more particular embodiments, those skilled in the art will recognize that many changes may be made thereto without departing from the scope of the present invention, which is set forth in the claims that follow.
