Description

[Technical Field]

[0001] This disclosure relates to the field of restorative dentistry. This disclosure relates to a method for preparing dental prostheses and related scannable temporary abutments. [Background technology]

[0002] Odontia, or tooth absence, is a global public health problem. Odontia can result from biological disease processes, such as tooth decay, periodontal disease, trauma, and oral cancer. Odontia is associated with several comorbidities that can significantly impact an individual. As expected life expectancy increases, it is likely to continue to have a high prevalence in the future. Full arch implant prostheses are widely used in restorative dentistry to restore smiles in patients with odontia and / or partial odontia.

[0003] Digital technology is being introduced in restorative dentistry to provide accurate digital implant impressions. During the reconstruction of fixed implants and before the fabrication of prosthetic prototypes, full arch impressions can be performed using digital scanning. That is, multiple intraoral scans can be performed to determine the three-dimensional implant position and contour of the temporary prosthesis. However, superimposing multiple datasets generated by multiple scans to create a model of the temporary prosthesis presents a significant challenge. This stems from the lack of a stable intraoral reference point when performing the scans. Certain techniques, including the use of self-adhesive alignment markers, scan posts, and / or surgical fixation pins, have been described to overcome this obstacle.

[0004] However, the proposed techniques are cumbersome. They require numerous intraoral scans and interventions on the patient because they necessitate the placement of alignment markers and / or surgical pins, followed by the need to perform multiple scans to obtain a good digital image of the patient's mouth, and finally, the alignment markers and / or surgical pins are removed and the temporary prosthesis is inserted. Self-adhesive alignment markers are simply placed on unfixed soft tissue, and therefore they may move between scans, potentially making the images unusable / inaccurate, requiring the dentist to redo scans and increasing the time the patient has to spend in the dental chair. Surgical pins are difficult for scanners to detect due to their reflective surface, and therefore increase the number of scans required to obtain a usable image. This is time-consuming and uncomfortable for patients with odontopathy and / or partial odontopathy.

[0005] Other methods are known for performing intraoral scans to generate models of the jaws of odontoid patients. For example, Marini et al. (J. Prosthotontics, 2021, 0, 1) describe a method for performing a first soft tissue scan using a scan body mounted on a scan post configured to accept a long scannable screw. Once the first scan is complete, the long scannable screw and scan post are removed. A temporary abutment is then placed, and a temporary denture is attached and secured to this temporary abutment with the long scannable screw, and a second scan is performed on the temporary denture. After the second scan is performed, the scannable screw is removed and replaced with a conventional prosthetic screw, and then the temporary prosthesis can be provided to the patient. Any removal and insertion of devices such as the scan body, temporary abutment, and prosthetic screw requires intraoral intervention on the patient, which is time-consuming, uncomfortable for the patient, and may damage the surface of the patient's soft tissues that have not yet healed, potentially requiring a longer healing time before the final prosthesis can be provided. [Overview of the project]

[0006] Therefore, there is a need for methods and devices for preparing dental prostheses that can mitigate, alleviate, or address existing shortcomings, provide a shorter and more accurate method for preparing dental prostheses, enhance patient comfort, and reduce the time patients spend in the dental chair.

[0007] A method for preparing dental prostheses is disclosed. The method includes placing a plurality of temporary abutments, each having a scannable member, on a dental implant. The method includes performing a first scan of the plurality of temporary abutments, each having a scannable member. The method includes placing a temporary prosthesis on a dental implant using the plurality of temporary abutments, each having a scannable member. The method includes performing a second scan of the temporary prostheses placed on the plurality of temporary abutments, each having a scannable member. The method includes generating a model of the final prosthesis based on the first and second scans using computer-aided design (CAD) software.

[0008] A scannable temporary abutment for determining the position of a dental implant is disclosed. The scannable temporary abutment comprises a temporary abutment and a scannable member, the scannable temporary abutment being configured to be attached to a dental implant.

[0009] A kit is disclosed comprising a scannable member and screws for securing the scannable member to a temporary abutment.

[0010] The advantage of this disclosure is that it is possible to increase the accuracy and speed of the scanning method while reducing the time the patient spends in the chair. By placing a scannable temporary abutment, such as a temporary abutment equipped with a scannable component, on the dental implant, the scan can be performed on the same temporary abutment used to secure the temporary prosthesis to the dental implant. Therefore, additional alignment markers, scan posts and / or surgical fixation pins are no longer required, resulting in less stress on the patient's soft tissue and thus faster soft tissue healing. Thus, the additional step of replacing the alignment markers, scan posts and / or surgical fixation pins with the temporary abutment after the scan is performed becomes unnecessary, and thus the number of steps in the overall method can be reduced. By using a scannable temporary abutment, the scannable component can be removed after the scan is performed, leaving the temporary prosthesis on the dental implant. This reduces the number of intraoral interventions required for the preparation of the dental prosthesis and reduces damage to the patient's soft tissue caused by attaching and removing components during scanning. Furthermore, scanners used to perform scanning, such as scanning devices, can be disturbed by soft tissue during scanning of odontopathy and / or partial odontopathy, potentially leading to errors in image stitching during scanning. This disclosure overcomes this problem by allowing the scanner to be guided by the morphology of the temporary prosthesis teeth, thus enabling faster image stitching with higher accuracy and less deviation. Consequently, additional scanning and / or additional post-processing of scanned images may be reduced or no longer required, further shortening the time required to prepare the temporary prosthesis model and the final dental prosthesis. Moreover, the use of temporary dentures in this method allows for better preparation and fitting of the final prosthesis. Temporary dentures can be used to evaluate aesthetics and voice.If temporary dentures do not fit well with the tissue, or if the required aesthetic or occlusal adjustments are minor, these can be addressed directly on the prototype during treatment, and the modified prototype can then be rescanned as a reference for the fabrication of the final prosthesis. The time efficiency of this method can be economically beneficial to all parties involved (i.e., the patient, dentist, dental clinician, and clinical laboratory).

[0011] The above and other features and advantages of this disclosure will be readily apparent to those skilled in the art through a detailed description of the following examples with reference to the accompanying drawings. [Brief explanation of the drawing]

[Figure 13] This block diagram shows an exemplary computer-controlled manufacturing tool as described in this disclosure. [Modes for carrying out the invention]

[0013] Various examples and details are described below, with reference to the drawings where applicable. Note that the drawings may or may not be drawn to scale, and that elements of similar structure or function are represented by the same reference numerals throughout the drawings. Note that the drawings are intended solely to facilitate the explanation of the examples. They are not intended to be an exhaustive description of this disclosure or a limitation on the scope of this disclosure. Furthermore, the illustrated examples do not necessarily have all the embodiments or advantages shown. Embodiments or advantages described in relation to a particular example are not necessarily limited to that example and may be implemented in any other example, even if not shown or explicitly described as such.

[0014] This disclosure provides a method for improving the quality of a model and patient comfort during the process. A method for preparing a dental prosthesis is disclosed. The method may be performed by a dental prosthesis manufacturing system. The dental prosthesis manufacturing system may comprise a scanner, such as an intraoral scanner, and a computer-controlled manufacturing tool, such as a 3D printer, a lathe, and / or a casting machine. The scanner may comprise a memory circuit, a processor circuit, an imaging circuit, and an interface. The computer-controlled manufacturing tool may comprise a memory circuit, a processor circuit, and an interface. The method includes placing a plurality of scannable temporary abutments, such as a plurality of temporary abutments each comprising a scannable member, onto each dental implant. A dental implant is a medical device surgically implanted in the jaw of a person with odontopathy and / or partial odontopathy, such as a person who is missing one or more teeth, to restore the person's ability to chew or appearance. A dental implant provides support for an artificial tooth, such as a prosthesis, crown, bridge, or denture. The temporary abutment is configured to fix the temporary prosthesis to the dental implant. A temporary abutment can be understood as an abutment configured to fix a temporary prosthesis to a dental implant for a limited period of time, until the final prosthesis is ready to be placed in the patient's jaw. In other words, a temporary abutment is not configured to be permanently fixed to a dental implant. A temporary abutment is configured to remain in the mouth of an odontoid and / or partially odontoid patient when the temporary prosthesis is in place. A temporary prosthesis can be understood as a temporary prosthesis configured to be placed on a dental implant for a limited period of time, such as until the final prosthesis is manufactured.

[0015] In one or more exemplary methods, arranging a plurality of temporary abutments, each having a scannable member, includes arranging the plurality of temporary abutments on each dental implant, and subsequently arranging the plurality of scannable members on each temporary abutment. In one or more exemplary methods, arranging a plurality of temporary abutments, each having a scannable member, includes arranging the scannable member on each temporary abutment of the plurality of temporary abutments. In one or more exemplary methods, arranging the scannable member on each temporary abutment of the plurality of temporary abutments includes screwing the scannable member to each temporary abutment. In one or more examples, the scannable member may have a first occlusal surface configured to occlude with a second occlusal surface of the temporary abutment. The first occlusal surface may be a first thread, such as an internal or external thread, configured to screw into a corresponding second thread in the temporary abutment. The second occlusal surface may be a second thread. In one or more examples, the scannable member may be configured to accept a screw. The screw may be configured to screw into the temporary abutment. The scannable member may, for example, have a through-hole (such as a lumen) for receiving the screw. The screw may be a prosthetic screw configured to secure the temporary prosthesis to the dental implant without interfering with the patient's fitting of the temporary prosthesis. The prosthetic screw may be configured not to protrude outward from the temporary abutment when the temporary abutment is secured to the dental implant using the screw.

[0016] In one or more exemplary methods, arranging each scannable member on each of the multiple temporary abutments includes clipping the scannable member onto each temporary abutment.

[0017] In one or more exemplary methods, the scannable member may be an integral part of the temporary abutment. Therefore, the method may include arranging multiple temporary abutments, each having an integrated scannable member, on a dental implant. In one or more exemplary methods, the dental implant may be a dental implant placed in the patient's mouth.

[0018] The method includes performing a first scan of a plurality of temporary abutments, each having a scannable member. The first scan is performed to obtain information about one or more dental implants, such as reference coordinates for one or more dental implants, which may be provided to computer-aided design (CAD) software and / or computer-aided manufacturing (CAM) software. The first scan may be a three-dimensional (3D) scan. The first scan may be performed using an intraoral scanner. The intraoral scanner can scan the plurality of scannable members to generate information indicating the location of one or more dental implants in the mouth of a patient with odontopathy and / or partial odontopathy. During the first scan, a first dataset is provided. The first dataset may show implant reference coordinates, as well as one or more of the morphologies of the jawbone of a patient with odontopathy and / or partial odontopathy, for example, the morphologies of the maxilla and / or mandible of a patient with odontopathy and / or partial odontopathy.

[0019] In one or more exemplary methods, performing a first scan includes acquiring first scan data, such as a first dataset, showing a plurality of scanlable temporary abutments, each having a scanlable member, positioned on each dental implant. The first scan data can be acquired using a scanner, such as a scanning device. In one or more examples, the scanner, such as a scanning device, comprises memory circuitry, processor circuitry, imaging circuitry, and interfaces. The scanner may be configured to perform any of the methods disclosed herein. In other words, the scanner may be configured to perform a first scan, for example, using imaging circuitry and / or memory circuitry, to acquire first scan data showing a plurality of scanlable temporary abutments, each having a scanlable member, positioned on each dental implant.

[0020] In one or more exemplary methods, the method involves placing a temporary prosthesis on a dental implant using a plurality of temporary abutments, each having a scannable member. Preferably, the plurality of temporary abutments do not need to be removed to place the temporary prosthesis. A temporary prosthesis is a temporary dental device that replaces one or more missing teeth or covers a tooth defect. In other words, a temporary prosthesis can be a set of tooth replacements. A temporary prosthesis is a prosthesis that can be used temporarily by a patient until a final prosthesis, such as a permanent prosthesis that provides better fit and greater comfort than a temporary prosthesis, is manufactured. Temporary prostheses are configured to be worn for a limited time, such as to bridge a gap from the removal of the patient's actual teeth until the completion of the final prosthesis. Final prostheses have better durability and are configured to be worn for several years. Temporary and / or temporary prostheses may be one or more of implants, crowns, bridges, dentures, and veneers. In one or more exemplary prostheses, the temporary prosthesis can be removable or permanently fixed in the mouth of a patient with odontopathy and / or partial odontopathy. In one or more exemplary methods, placing the temporary prosthesis on a dental implant involves embedding multiple temporary abutments into the temporary prosthesis. The multiple temporary abutments may be embedded into the temporary prosthesis by gluing and / or cementing the temporary abutments to the temporary prosthesis or by other means.

[0021] A temporary prosthesis may be placed on a dental implant by providing a temporary prosthesis, such as a temporary denture, which has a pre-formed hole that is sufficiently large and positioned so that the temporary prosthesis can be inserted on top of multiple temporary abutments. The temporary prosthesis may have one hole for each temporary abutment. In one or more exemplary methods, the position of the hole in the temporary prosthesis may be determined based on information indicating the position of one or more dental implants, such as implant reference coordinates obtained from a first scan. In one or more exemplary methods, the position of the hole may be obtained from a dental impression made before the implant was inserted into the patient's mouth. The temporary abutments and the temporary prosthesis are then mounted together, and the hole may be closed with an adhesive, most preferably a temporary adhesive, such as glue, or a cement, such as temporary cement.

[0022] In one or more exemplary methods, placing a temporary prosthesis on a dental implant may include removing a scannable member and / or temporary abutment from the dental implant after a first scan has been performed. The temporary abutment may then be fixed to the temporary prosthesis by inserting the temporary abutment into a pre-formed hole in the temporary prosthesis and fixing the temporary abutment to the temporary prosthesis using, for example, an adhesive, such as glue, or cement, preferably temporary glue or cement. The temporary prosthesis may have a pre-formed hole large enough to receive the temporary abutment. The location of the hole in the temporary prosthesis may be determined based on information indicating the location of one or more dental implants, such as implant reference coordinates obtained from the first scan. In one or more exemplary methods, the location of the hole may be obtained from a dental impression made before the implant was inserted into the patient's mouth. The hole in the temporary prosthesis may then be closed with an adhesive, such as glue or cement. After the temporary abutment is fixed to the temporary prosthesis, the temporary prosthesis can be fixed to the dental implant using the temporary abutment and fastening means such as dental screws.

[0023] This method includes performing a second scan on a temporary prosthesis placed on multiple temporary abutments, each having a scannable member, in order to obtain implant reference coordinates for the morphology of the temporary prosthesis. The second scan has the advantage of increasing the number of data points collected by the scanner during the first scan and is used as a reference scan for the model of the final prosthesis. In fact, during the first scan of the mouth of anodontoid and / or partially anodontoid patients, it is difficult for the scanner to collect data points for soft tissue, so the scanner mainly maps the soft tissue and collects data points related to multiple temporary abutments, each having a scannable member, in order to obtain implant reference coordinates. During the second scan, a second dataset is generated that serves as a basis for designing the model of the final prosthesis. The second dataset includes data showing multiple temporary abutments, each having a scannable member, in order to obtain implant reference coordinates and the landscape of the temporary prosthesis, and thus provides an accurate model of the final prosthesis. The second dataset may show one or more implant reference coordinates, as well as the morphology of the temporary prosthesis, such as the morphology of the maxillary and / or mandibular temporary prosthesis. By using the same type of temporary abutment for both the first and second scans, the risk of the scannable component not being positioned in the same location during the first and second scans can be reduced and / or eliminated. Furthermore, all collected data points can be used to design the final prosthesis and correct any misalignment or problems observed during the scanning of the temporary denture, without requiring additional intraoral or extraoral scans, in order to provide the patient with a high-quality final prosthesis.

[0024] In one or more exemplary methods, performing a second scan includes acquiring second scan data, such as a second dataset, showing a plurality of temporary prostheses arranged on a plurality of temporary abutments, each having a scannable member. The second scan data can be acquired using a scanner, such as a scanning device. The scanner can be configured to perform a second scan, for example, using an imaging circuit and / or memory circuit, to acquire second scan data showing a plurality of temporary prostheses arranged on a plurality of temporary abutments, each having a scannable member.

[0025] This method includes generating a model of a final prosthesis based on a first scan based on first scan data or a first dataset, etc., and a second scan based on second scan data or a second dataset, etc. In one or more exemplary methods, the model of the final prosthesis may be generated using computer-aided design (CAD) software. The CAD software may be embodied in the form of executable logic routines (e.g., lines of code, software programs, etc.) stored in a non-temporary computer-readable medium (e.g., the scanner's memory circuit) and executed by the scanner's processor circuit. In one or more exemplary methods, generating the model includes aligning the position of each scannable member from the first scan with the position of each corresponding scannable member from the second scan. In other words, generating the model may include superimposing the corresponding scannable members from the first and second scans. The model may include information necessary to manufacture high-precision dental prostheses specifically tailored to the oral morphology of patients with odontopathy and / or partial odontopathy, such as information on the position of implants and / or existing prostheses, such as temporary prostheses, and, where possible, information on soft tissue. This allows for the provision of a final prosthesis with an accurate fit to the patient's oral morphology (and subsequently mounted on a dental implant) without the need to perform multiple trial fits to test and fit the occlusion of the dental prosthesis. Thus, the risk of having to remake the dental prosthesis can be reduced. Furthermore, the fit of the dental prosthesis can be made more accurate, thereby improving the wearing comfort of patients with odontopathy and / or partial odontopathy. In one or more exemplary methods, the scanner may be configured to generate a model of the final prosthesis, for example, by running CAD software using, for example, a processor circuit, to generate the final model based on first scan data or a first data set and second scan data or a second data set. In one or more exemplary methods, the scanner may be configured to superimpose scan data showing corresponding scannable members from the first scan and the second scan.

[0026] In one or more exemplary methods, the method includes manufacturing a final prosthesis, such as a final denture, based on a digital model of the final prosthesis. The final prosthesis can be manufactured by one or more techniques known to those skilled in the art, such as milling, casting, additive manufacturing such as 3D printing, turning, and casting. In one or more exemplary methods, manufacturing the final prosthesis includes transmitting manufacturing instructions for manufacturing the final prosthesis to a computer-controlled manufacturing tool, such as a 3D printer, a turning machine, and / or a casting machine, for example, via a scanner interface. The manufacturing instructions may include data indicating a model of the final prosthesis. The computer-controlled manufacturing tool may be configured to receive manufacturing data from the scanner, for example, via an interface of the computer-controlled manufacturing tool, and to store the manufacturing instructions in a memory circuit of the computer-controlled manufacturing tool, for example. In one or more exemplary methods, the computer-controlled manufacturing tool may be configured, for example, by a processor circuit of the computer-controlled manufacturing tool to execute the manufacturing instructions for manufacturing the final prosthesis, such as manufacturing.

[0027] In one or more exemplary methods, the method includes removing (e.g., separating) each scannable member from each of the multiple temporary abutments. In one or more exemplary methods, for example, if the scannable members are screwed to the temporary abutments, removal includes unscrewing and removing each scannable member from each of the multiple temporary abutments. In one or more exemplary methods, for example, if the scannable members are clipped onto the temporary abutments, removal includes unclipping and removing each scannable member from each of the multiple temporary abutments. In one or more exemplary methods, for example, if the scannable members are integral with the temporary abutments, removal includes machining the scannable members of each temporary abutment. The scannable members can be machined away from each temporary abutment by cutting and / or grinding the scannable members of each temporary abutment.

[0028] A scannable temporary abutment for determining the position of a dental implant is disclosed, comprising a temporary abutment and a scannable member. The temporary abutment is an abutment used in the fabrication of a temporary prosthesis. The temporary abutment can be a temporary abutment known to those skilled in the art, for example, the temporary abutment may be cylindrical in shape. The temporary prosthesis may be glued or cemented onto the temporary abutment (e.g., using temporary glue or cement), or the temporary abutment may be incorporated into the temporary prosthesis. The scannable member is a member designed to provide accurate scanning results. In other words, the scannable member can be configured to be detectable by a scanner, such as a scanning device (e.g., an intraoral scanner or a dental scanning wand), which can accurately match the parameters of the digital scannable member to physical parameters. The parameters may be one or more of the height, width, length, and shape of the scannable member. As is done in known systems, using different devices to mount scannable screws for different scans, such as scan posts and temporary abutments, can introduce errors between scans. For example, scannable screws may not be at the same height relative to the dental implant during scanning, as the height depends on how deeply the scannable screw is screwed into the scan post in the first scan and into the temporary abutment in the second scan. The height may also depend on the size, such as the depth of the screw channel in the scan post and temporary abutment used throughout the workflow. Variations in height can also lead to differences in scan landscaping and stitching. Differences in the abutments used, such as between scan posts and temporary abutments, can also lead to differences in the angle of the abutment relative to the dental implant, which can also create differences in mapping.A scannable temporary abutment according to one or more examples disclosed herein has the advantage of allowing easy positioning, removal, and repositioning of a scannable member onto the temporary abutment, or integration with the temporary abutment. Furthermore, the position and height of the scannable member are fixed by the temporary abutment, improving the coordination and overlap of two scans compared to known systems where both the scan post and the scannable member (e.g., scannable screw) must be moved between scans. The scannable temporary abutment according to this disclosure is configured for use in both scans where the temporary prosthesis is not placed on the dental implant and scans where the temporary prosthesis is placed on the dental implant, thereby reducing the risk that the scannable member will not be positioned at the same height and / or angle relative to the dental implant in two scans. The scannable temporary abutment according to this disclosure is configured to be attached to a dental implant. The dental implant may be a dental implant placed in the oral cavity, for example, in the jawbone, of a patient with odontopathy and / or partial odontopathy. A scannable temporary abutment can be understood as a temporary abutment that comprises a scannable member or is configured to accept a scannable member. Scannable can be understood as being detectable by a scanner, such as an intraoral scanner, in order to generate a dataset for CAD modeling of the scannable member and / or temporary abutment.

[0029] In one or more exemplary scannable temporary abutments, the scannable member has a substantially cylindrical shape and / or cylindrical shape. Substantial cylindrical shape can be understood as the main shape of the scannable member being cylindrical, but including one or more notches or protruding sections. The scannable member may include a top surface, a base surface, and a side surface. The side surface may connect the top surface and the base surface. The base surface may be the bottom surface. The top surface may be the surface that faces away from the dental implant when the scannable member is placed on the dental implant via the temporary abutment. The top surface may be the surface that faces the dental implant when the scannable member is placed on the dental implant via the temporary abutment.

[0030] In one or more exemplary scannable temporary abutments, the scannable member includes a position indicator configured to be detectable by a scanner, such as an intraoral scanner. The position indicator may be a surface different from an adjacent surface. The position indicator may be a plane, such as a facet. The plane may extend from the top surface of the scannable member to the side surface of the scannable member at a first angle with respect to the longitudinal axis of the scannable member. By adding a position indicator to the scannable member, the shape of the scannable member can be made asymmetrical, which can improve the detectability of the scannable member by a scanner compared to a solution using a scannable screw. The scanner may be configured to perceive and / or detect the angle of the position indicator, and this angle may be used as a coordinate for aligning the scan dataset. The side surface of the scannable member may be the envelope surface of the scannable member, for example, a cylindrical scannable member. The position indicator is a plane of the scannable member, such as a facet inclined with respect to the side surface, and is, for example, a plane having a normal axis positioned at a first angle with respect to a longitudinal axis, such as the longitudinal central axis of the scannable member. The first angle can be greater than 0° and less than 90° such that the plane is not parallel to either the top or the side.

[0031] In one or more exemplary scannable temporary abutments and / or scannable members, the position indicator is L-shaped. The position indicator may be a notch in the body of the scannable member such that a surface, such as a first surface of the position indicator, is parallel to the longitudinal axis of the scannable member. In one or more examples, a second surface of the position indicator may be substantially perpendicular to the first surface, such as substantially perpendicular to the longitudinal axis of the scannable member.

[0032] In one or more exemplary scannable members, the surface of the scannable member may be treated to reduce surface reflectivity, such as surface light reflectivity. The surface of the scannable member can be treated by etching, for example, by using an etching method. Thus, in one or more exemplary scannable members, the scannable member includes an etched surface. The surface of the scannable member may be etched to increase surface roughness. By increasing the roughness of the scannable member, the treated surface may be less reflective than the untreated surface, thus improving the scannability of the scannable member. This can reduce reflected light from the scanner, which could otherwise adversely affect the scanning results and prevent the scanner from providing an accurate image of the object being scanned. Scannability can be understood as how well the scannable member can be detected by the scanner. A device with poor scannability may not be detectable by the scanner or may provide poor scanning results, such as poor image quality, by introducing disturbances to the scanner during scanning. A device with good scannability may be easily detectable by the scanner or may provide good scanning results, such as good image quality.

[0033] In one or more exemplary scannable temporary abutments, the temporary abutment and / or scannable member may be made of metal, metal alloy, composite material and / or polymer. In one or more exemplary scannable temporary abutments, the temporary abutment and / or scannable member may be made of, for example, polyether ether ketone (PEEK) or polyvinyl alcohol (PVA).

[0034] In one or more exemplary scannable temporary abutments, the temporary abutment and / or scannable member may be made of metal or a metal alloy, for example, the temporary abutment and / or scannable member may be made of titanium and / or a titanium alloy. In one or more exemplary temporary abutments, titanium may be surface-treated to increase surface roughness. The advantage of treating the surface of the scannable temporary abutment and / or scannable member is that the surface roughness can be increased, and therefore the surface reflectivity can be reduced, thereby improving scanability. By increasing surface roughness, it is possible to reduce reflected light from the scanner, which could otherwise negatively affect the scanning results and prevent the scanner from providing an accurate image of the object being scanned. When a metal surface is smoothed, light from the scanner may be reflected off the metal surface and returned to the scanner, which could obscure the scanning results, and the scanner may not be able to create an accurate image of the object being scanned. Non-metallic materials such as composite materials and / or polymers have the advantage of having low reflectivity and / or non-reflectivity on their surfaces, and therefore less light is reflected back to the scanner, thus improving the scannability of temporary abutments and / or scannable members.

[0035] In one or more exemplary scannable temporary abutments, the scannable member comprises a base, such as a base section, configured to clip onto the temporary abutment. The base of the scannable member may be configured to receive the temporary abutment in one or more exemplary scannable temporary abutments. The base of the scannable member may include a hollow portion, such as a cavity, which can clip onto the temporary abutment by receiving the temporary abutment within the hollow portion.

[0036] The scannable member may have an outer diameter in the range of 4.0 to 4.8 mm, for example, in the range of 4.2 to 4.6 mm. The scannable member may have a length in the range of 2.4 to 5.2 mm, such as the longitudinal extension of the scannable member.

[0037] In one or more exemplary scannable members, the scannable member may include a first projection, also known as a clip-on projection, configured to engage with a temporary abutment. The first projection may be configured to be inserted into a cavity, such as a through-hole at the top of the temporary abutment. The first projection may be located at the base, such as a base section of the scannable member, or it may extend in the longitudinal direction of the scannable member. The first projection may be hollow or solid. The size and shape of the first projection can be selected such that it is supported radially or otherwise by one or more side walls of a cavity, such as a through-hole, of the temporary abutment. The first projection may have an outer diameter equal to the inner diameter of the cavity, such as a through-hole. In one or more exemplary scannable members, the scannable member may include a plurality of projections, such as a first projection and a second projection, configured to engage with a temporary abutment. In other words, the scannable member may include one or more projections configured to engage with an abutment, such as one or more clip-fastening projections. The second projection may have the same or similar characteristics as the first projection, e.g., size and shape. One or more projections, such as the first and / or second projections, may extend radially around at least a portion of the outer circumference of the base of the scannable member. In other words, the projections may be radial projections.

[0038] In one or more exemplary scannable members, the base may include grooves such as body clipping grooves or body connecting grooves for receiving base clipping projections. The body can be releasably connected to the base by inserting the body into the base until the base clipping projection engages with the body clipping groove. In one or more exemplary scannable members, the base of the scannable member may include an insert, which is positioned on the inner surface of the base and configured to engage with the body away from the scannable member. The insert may be a matrix, for example, a matrix made of polymer, which includes grooves for receiving base clipping projections of the body. The base clipping projection may be hollow or solid. The size and shape of the base clipping projection can be selected so that the base clipping projection is supported by one or more side walls of the base. The base clipping projection may have, for example, an outer diameter equal to the inner diameter of the base.

[0039] In one or more exemplary scannable members, the scannable member may include a tool receptacle, such as a screw channel, located on the upper surface of the body of the scannable member. The tool receptacle may be configured to accept a tool, such as a screwdriver, to facilitate connection between the scannable member and the abutment, such as when inserting the scannable member into the cavity of the abutment. The tool receptacle may have a star shape, such as a Torx shape, a hexagonal shape, a Phillips shape, a grooved socket shape, a wing shape, such as a three-wing shape, a square shape, and / or a clutch shape.

[0040] In one or more exemplary scannable temporary abutments, the base of the scannable member comprises a plurality of plates or wings configured to engage with the temporary abutment. The scannable member may comprise, for example, two, three, four, or five plates. The plurality of plates may extend longitudinally from the base of the scannable member. The plurality of plates may be configured to be inserted into a cavity, such as a through hole at the top of the temporary abutment. When inserted into the cavity of the temporary abutment, the plurality of plates may be configured to exert a radial force on the temporary abutment to secure the scannable member to the temporary abutment. The plurality of plates may be uniformly distributed on the base of the scannable member. In one or more exemplary scannable temporary abutments, each of the plurality of plates may be positioned on a first projection of the scannable member.

[0041] In one or more exemplary scannable temporary abutments, the temporary abutment and the scannable member may be configured to create a shape fit, such as by creating a mechanical fit. The temporary abutment may have, for example, one or more recesses located on the surface of a cavity. The one or more recesses may be configured to receive one or more projections located radially outward on the scannable member, such as on a plate of the scannable member. Thus, the scannable member can be clipped onto the temporary abutment by inserting the scannable member into the temporary abutment until the projections of the scannable member engage with the recesses of the temporary abutment. Correspondingly, in one or more exemplary scannable temporary abutments, the temporary abutment may have projections and the scannable member may have recesses. The mutually engaging projections and recesses can further provide tactile feedback to the user of the scannable member, such as a dentist attaching the scannable member to the temporary abutment, indicating that the scannable member is properly seated on the temporary abutment. This ensures that the scannable member is properly seated on the temporary abutment and therefore positioned in the same location for each scan. This guarantees that the position of the scannable member is the same in all scans and therefore allows for proper alignment of images from multiple scans to create a model.

[0042] In one or more exemplary scannable temporary abutments, the base of the scannable member includes a magnet, such as a first magnet, configured to magnetically connect the scannable member to the temporary abutment. In one or more exemplary scannable temporary abutments, the temporary abutment may be made of a magnetic material that attracts the magnet of the scannable member. In one or more exemplary scannable temporary abutments, the temporary abutment may include a magnet, such as a second magnet having the opposite pole to the magnet placed on the scannable member, thereby attracting and securing the scan body to the temporary abutment. Thus, the scannable member can be configured to magnetically clip onto the temporary abutment, such as magnetically attracting and securing the scannable member to the temporary abutment. The magnetic material and / or the first magnet engaging with the second magnet can provide tactile feedback to the user of the scannable member (e.g., a dentist) indicating that the scannable member is properly seated on the temporary abutment.

[0043] In one or more exemplary scannable temporary abutments, the scannable member is configured to be screwed onto the temporary abutment. In one or more examples, the scannable member may have through holes configured to receive screws for securing the scannable member to the temporary abutment.

[0044] In one or more examples, the scannable member may have threads for screwing the scannable member into a temporary abutment. The scannable member may, for example, have external threads, and the temporary abutment may have internal threads configured to receive the external threads of the scannable member. Correspondingly, in one or more exemplary scannable temporary abutments, the scannable member may have internal threads, and the temporary abutment may have external threads configured to receive the internal threads of the scannable member.

[0045] In one or more exemplary scannable temporary abutments, the scannable temporary abutment, such as an assembly of the temporary abutment and a scannable member, has a length selected such that when the temporary prosthesis is fixed to the dental implant via the temporary abutment, the scannable member is approximately the same length as the tooth apex of the temporary prosthesis. In another example, the length of the scannable temporary abutment may be selected such that when the temporary prosthesis is fixed to the dental implant via the temporary abutment, the scannable member protrudes above the temporary prosthesis. The length may be, for example, in the range of 5 to 20 mm, for example in the range of 8 to 14 mm, for example in the range of 10 to 13 mm, for example in the range of 11.5 mm.

[0046] A kit is disclosed comprising a scannable member and screws for securing the scannable member to a temporary abutment.

[0047] The solutions provided in this disclosure are described in more detail below with reference to the drawings. The drawings are schematic and simplified for clarity and merely illustrate details that aid in understanding this disclosure, while other details are omitted. Throughout, the same reference numerals are used for identical or corresponding parts.

[0048] Figure 1 is a flowchart illustrating an exemplary method for preparing a dental prosthesis according to the present disclosure. In one or more exemplary methods, the method includes step S101 of placing a plurality of scannable temporary abutments, such as a plurality of temporary abutments each having a scannable member, onto a dental implant. The scannable temporary abutments can be screwed onto the dental implant, and the scannable members can then be placed on the temporary abutments.

[0049] Step S101, which involves arranging a plurality of scannable temporary abutments, each having a scannable member, may, in one or more exemplary ways, include step S101A, which involves arranging the scannable members on each of the temporary abutments of the plurality of scannable temporary abutments.

[0050] In one or more exemplary methods, for example, if a scannable member is configured to be screwed onto a scannable temporary abutment, step S101A of positioning the scannable member onto each of the scannable temporary abutments of a plurality of temporary abutments includes step S101AA of screwing the scannable member onto each of the scannable temporary abutments.

[0051] In one or more exemplary methods, for example, if the scannable members are configured to be clipped onto scannable temporary abutments, step S101A of positioning each of the scannable members onto each of the scannable temporary abutments of a plurality of scannable temporary abutments includes step S101AB of clipping the scannable members onto each scannable temporary abutment.

[0052] The method includes step S103 of performing a first scan of a plurality of scannable temporary abutments 20, each having a scannable member 10 positioned on each dental implant.

[0053] In one or more exemplary methods, step S103 of performing a first scan includes step S103A of acquiring first scan data showing a plurality of scannable temporary abutments, each having a scannable member, positioned on each dental implant. The first scan data may be acquired using a scanner 40.

[0054] An exemplary method of step S103, in which a first scan is performed, will be described in more detail with reference to Figure 1B. The first scan can be performed using a scanner, such as an intraoral scanner. The scanner 40 can scan a plurality of scannable members 10 to generate information indicating the location of one or more dental implants in the mouth of a patient with odontopathy and / or partial odontopathy. During the first scan, a first data set is generated. The first data set may show implant reference coordinates, as well as one or more of the morphologies of the jawbone of a patient with odontopathy and / or partial odontopathy, such as the morphologies of the maxilla and / or mandible of a patient with odontopathy and / or partial odontopathy. The first scan may be performed before any prostheses, such as temporary prostheses, are placed in the patient's mouth. In one or more exemplary methods, the first scan may provide information about the patient's soft tissues. The method includes step S105, in which a temporary prosthesis is placed on a dental implant using a plurality of temporary abutments, each having a scannable member. After the first scan is performed, a temporary prosthesis can be placed on the dental implant, and a second scan including the temporary prosthesis can be performed. In one or more exemplary methods, the step S105 of placing the temporary prosthesis on the dental implant may include the step S105A of embedding a plurality of temporary abutments into the temporary prosthesis. The plurality of temporary abutments may be embedded into the temporary prosthesis by gluing and / or cementing the temporary abutments to the temporary prosthesis (for example, using temporary glue and / or temporary cement).

[0055] The method includes step S107 of performing a second scan on a plurality of temporary prostheses placed on a plurality of temporary abutments, each having a scannable member.

[0056] In one or more exemplary methods, step S107 of performing a second scan includes step S107A of acquiring second scan data, such as a second dataset, showing temporary prostheses placed on a plurality of temporary abutments, each having a scannable member. The second scan data may be acquired using a scanner, such as a scanning device.

[0057] An exemplary method of performing the second scan in step S107 will be described in more detail with reference to Figure 1C. The second scan can be performed using a scanner 40, such as an intraoral scanner. The scanner 40 can scan the prosthesis 50 together with a plurality of scannable temporary abutments 20, each having a scannable member 10, to generate information indicating the position of the prosthesis 50 relative to one or more dental implants. During the second scan, a second dataset is generated. The second dataset may show one or more implant reference coordinates, as well as the morphology of the prosthesis 50, such as the morphology of the maxillary and / or mandibular prosthesis.

[0058] In one or more exemplary methods, the method includes step S108 of removing each scannable member from each of the temporary abutments of a plurality of temporary abutments. In one or more exemplary methods, step S108 of removing each scannable member includes step S108A of unscrewing each scannable member from each of the temporary abutments of a plurality of temporary abutments. This may be the case, for example, when the scannable member is screwed to the temporary abutment.

[0059] In one or more exemplary methods, step S108 for removing each of the scannable members includes step S108B for removing each of the scannable members from the clips on each of the temporary abutments of a plurality of temporary abutments. This may be the case, for example, when the scannable members are clipped to the temporary abutments.

[0060] In one or more exemplary methods, for example, if a scannable member is integrated with a temporary abutment, step S108 for removing each of the scannable members includes step S108C for machining the scannable member away from its respective temporary abutment. Each scannable member can be machined away from its respective temporary abutment by cutting and / or grinding the scannable member away from the temporary abutment. The scannable member may be machined away from the temporary abutment to a first distance from the top surface of the scannable member. The first distance may be selected so that the remaining length of the temporary abutment does not protrude above the dental prosthesis attached to the temporary abutment, for example, beyond the dental prosthesis in the longitudinal direction of the temporary abutment. The machining step S108C may be performed intraoral or extraoral. In other words, in one or more exemplary methods, each scannable member may be machined away from the corresponding temporary abutment while the temporary abutment is positioned on the dental implant. In one or more examples, the temporary abutment can be removed from the dental implant before the scannable component is machined off from the temporary abutment.

[0061] This method includes a step S109 of generating a model of the final prosthesis based on a first scan and a second scan using CAD software. In one or more exemplary methods, the model generation step S109 includes aligning the position of each scannable member from the first scan with the position of each corresponding scannable member from the second scan, such that the position of each scannable member and / or temporary abutment in the first scan overlaps with the corresponding, for example, the same scannable member and / or temporary abutment in the second scan. In other words, the model generation step S109 may include superimposing the corresponding scannable members from the first scan and the second scan.

[0062] In one or more exemplary methods, the method includes a step S111 of manufacturing a final prosthesis based on a model of the final prosthesis. The final prosthesis may be manufactured using CAM software based on a model created by CAD software. Step S111 of manufacturing the final prosthesis may include one or more of additive manufacturing such as milling, 3D printing, turning, and casting.

[0063] Figures 2A to 2C show scannable members 10 configured to be placed on a temporary abutment, according to one or more first examples of the present disclosure. The scannable members 10 shown in Figures 2A to 2C have a cylindrical shape. An exemplary scannable member 10 comprises an upper end 11, a base end 12A (such as a first base end 12A), and a side 13. The base end may be located on the base 12 of the scannable member 10. The side 13 may connect the upper end 11 and the first base end 12A. The side 13 may vary in size from the upper end 11 to the base end 12A, such that the base 12 has a different diameter from the upper end 11. The upper end 11 may include the upper surface of the scannable member 10, such as the surface that faces away from the dental implant when the scannable member 10 is placed on the dental implant via the temporary abutment. The upper end 11 is the end of the scannable member that faces away from the dental implant when the scannable member 10 is placed on the dental implant via the temporary abutment. The base end 12A of the scannable member 10 may be a bottom surface, such as the surface that faces the dental implant when the scannable member 10 is placed on the dental implant via a temporary abutment.

[0064] Figure 2A shows a side view of a first exemplary scannable member 10. The first exemplary scannable member 10 may have a stepped shape in the longitudinal direction, and in particular, the side 13 may have a stepped shape. In this specification, a stepped shape means that the diameter of the scannable member may change along the longitudinal direction of the scannable member. The first exemplary scannable member may have a first diameter D1 toward the upper end 11, a second diameter D2 toward the base end 12A, and a length L. The first diameter D1 may be in the range of 4.0 to 4.8 mm, for example, 4.2 to 4.6 mm. The second diameter D2 may be in the range of 3.4 to 3.8 mm, for example, 3.6 mm. The length L may be in the range of 2.4 to 5.2 mm.

[0065] Therefore, the side surface 13 of the scannable member 10 may comprise a first section 13A located at the upper end 11 and a second section 13B located at the base end 12A. The second section 13B of the side surface 13 can be understood herein as the base 12. The first section 13A and the second section 13B of the side surface may be connected via a third section 13C, such as an inclined section. The third section 13C may have a first diameter D1 at the end connected to the first section 13A and a second diameter D2 at the end connected to the second section 13B. The exemplary scannable member 10 shown in Figures 2A to 2C may further comprise a position indicator 15 (not shown in Figures 2A to 2C), such as an inclined surface. In one or more exemplary scannable members, the position indicator 15 may be an inclined surface extending from the upper surface 11 of the scannable member 10 to the side surface 13 of the scannable member 10. The side surface 13 of the scannable member 10 may be the enveloping surface of the scannable member 10, for example, a cylindrical scannable member 10. The inclined surface 15 is a surface of the scannable member 10 that is inclined with respect to the side surface 13, such as being positioned at a certain angle with respect to the upper surface 11 of the scannable member 10.

[0066] Figure 2B shows a cross-sectional view of an exemplary first scannable member 10 along the cutting line AA shown in Figure 2A. The exemplary first scannable member is hollow and includes, for example, a through hole 14 extending through the center of the scannable member 10 in the longitudinal direction of the scannable member 10. The through hole 14 may be configured to receive a screw for securing the scannable member 10 to a temporary abutment. The base end 12A of the scannable member 10 may be configured to receive the temporary abutment. The hollow portion of the scannable member, such as the through hole 14, may have a different diameter at the base end 12A than at the upper end 11. The scannable member may be attached to a temporary abutment by inserting the temporary abutment into the through hole at the base end 12A of the scannable member 10 so that the scannable member is clipped to the temporary abutment. Thus, the scannable member 10 can be clipped onto a temporary abutment by receiving the temporary abutment in the hollow portion of the scannable member 10.

[0067] Figure 2C shows a perspective view of the first scannable member 10, which is an example of Figures 2A and 2B.

[0068] Figures 3A to 3E show scannable members 10 configured to be positioned on a temporary abutment, according to one or more second examples of the present disclosure. The exemplary scannable member 10 shown in Figures 3A to 3E comprises a base, such as a proximal end 12A, configured to clip onto the temporary abutment. The proximal end 12A of the scannable member 10 may have projections 16 protruding from the proximal end 12A, such as the surface of the proximal end 12A of the scannable member 10. The base of the scannable member 10 comprises a plurality of fins 17 configured to engage with the temporary abutment. The plurality of fins 17 may be positioned on the projections 16 or may form the projections 16. The scannable member 10 may comprise two, three, four, or five fins 17. The plurality of fins 17 may extend longitudinally from the proximal end 12A of the scannable member 10. The multiple fins 17 may be configured to be inserted into a cavity at the top of the temporary abutment, such as within the portion of the temporary abutment distal to the dental implant, when the temporary abutment is placed on the dental implant. The cavity may be, for example, a through-hole in the scannable temporary abutment. When inserted into the cavity of the temporary abutment, the multiple fins 17 may be configured to exert force radially on the temporary abutment in order to secure the scannable member to the temporary abutment. The multiple fins may be, for example, spring-loaded. The multiple fins 17 may be uniformly distributed at the base of the scannable member 10, such as being arranged at an angular distance of 360° / N (where N is the number of fins 17). The exemplary second scannable member 10 shown in Figures 3A to 3E has a substantially cylindrical shape. The scannable member 10 may have a diameter D1 in the range of 4.0 to 4.8 mm, for example, in the range of 4.2 to 4.6 mm, and its length L may be in the range of 2.4 to 5.2 mm.

[0069] Figure 3A shows a side view of the scannable member 10 as seen from the base end 12A of the scannable member 10. The exemplary scannable member 10 shown in Figure 3A comprises four thin plates arranged in a circular configuration. The plates are positioned at 90° angular distances from each other, but other configurations can be used. Figure 3B shows a side view of the scannable member 10 as seen from a direction perpendicular to the longitudinal axis of the scannable member 10. As can be seen, the thin plate 17 protrudes from the base end 12A of the scannable member 10. The thin plate may be located on the protrusion 16.

[0070] The scannable member 10 may be configured to create a shape fit with the temporary abutment. The scannable member 10 may have one or more protrusions 17A, such as radial projections, positioned radially outward on a thin plate of the scannable member 10, which are configured to engage with one or more recesses located on the surface of the cavity of the temporary abutment. Thus, the scannable member can be clipped onto the temporary abutment by inserting the scannable member into the temporary abutment until one or more radial projections 17A of the scannable member 10 engage with the recesses of the temporary abutment. Figure 3C shows a cross-sectional view of an exemplary second scannable member 10 along the cutting line BB shown in Figure 3B. The exemplary second scannable member is solid, such as having a solid core. Figure 3D shows a side view of the scannable member 10 as seen in the direction of the top surface 11 of the scannable member 10. Figure 3E shows a perspective view of the second scannable member 10, which is an example of those shown in Figures 3A to 3D.

[0071] Figures 4A to 4E show scannable members 10 configured to be positioned on a temporary abutment, according to one or more third examples of the present disclosure. The exemplary scannable members 10 shown in Figures 4A to 4E are similar to the scannable members according to one or more second examples shown in Figures 3A to 3E, except that the scannable member 10 includes a position indicator 15. According to one or more third exemplary scannable members, the position indicator 15 is a plane having a normal axis positioned at a first angle with respect to a longitudinal axis, such as the longitudinal central axis of the scannable member 10. The position indicator 15 is configured to be detectable by a scanner, such as an intraoral scanner. In the exemplary scannable members shown in Figures 4A to 4E, the position indicator 15 extends from the top surface 11 of the scannable member 10 toward the side surface 13 at a first angle with respect to the longitudinal axis of the scannable member 10. Thus, the plane extending along the plane 15 intersects the longitudinal axis and / or the side surface 13. The first angle can be greater than 0° and less than 90° such that the plane is not parallel to either the top surface 11 or the side surface 13. By providing a position indicator 15 on the scannable member 10, the detectability of the scannable member 10 by the scanner, such as the detectability of the orientation of the scannable member 10, can be improved. By improving the detectability of the scannable member 10, the image processing required to generate a model by aligning the first scan and the second scan, such as by superimposing the first scan and the second scan, can be reduced.

[0072] Figures 5A to 5F show scannable temporary abutments 20 according to one or more examples of the present disclosure. An exemplary scannable temporary abutment 20 comprises a scannable member 10. In the exemplary scannable temporary abutments shown in Figures 5A to 5F, the scannable member 10 is integral with the scannable temporary abutment 20 (e.g., integral with the temporary abutment 20). In one or more exemplary scannable temporary abutments, the scannable member may be separate from the temporary abutment and may be configured to be clipped to or screwed to the temporary abutment. The scannable temporary abutment 20 has a base section 21 including a base end 21A, an intermediate section 22, and an upper end 23. The intermediate section 22 may be located between the upper end 23 and the base section 21. The intermediate section 22 of the exemplary scannable temporary abutment 20 has a cylindrical shape. The base section 21 of the scannable temporary abutment 20 is configured to be positioned on a dental implant. The scannable temporary abutment 20 may be configured to be fixed to a temporary prosthesis for securing the temporary prosthesis to the dental implant. The scannable temporary abutment 20 may be fixed to the temporary prosthesis 20 by gluing and / or cementing the temporary abutment 20 to the temporary prosthesis 20. To ensure that the temporary prosthesis is securely fixed to the scannable temporary abutment 20, the intermediate section of the temporary abutment may include one or more longitudinal fixing means 24 to prevent the temporary prosthesis from sliding along the temporary abutment 20 in the longitudinal direction of the temporary abutment 20. The longitudinal fixing means 24 may be recesses and / or protrusions, such as grooves or ridges, located on the outer surface of the intermediate section. When a temporary prosthesis is bonded to a scannable temporary abutment by means of glue and / or cement bonding, the adhesive, such as glue and / or cement, engages with the longitudinal fixing means and thus can prevent the temporary prosthesis from moving in the longitudinal direction.In the exemplary scannable temporary abutment 20 shown in Figures 5A, 5C, and 5F, the longitudinal fixing means 24 is a groove positioned around the outer circumference of the intermediate section 22 of the scannable temporary abutment 20. The scannable member 10 may be positioned in the upper section of the scannable temporary abutment 20.

[0073] Figure 5D shows a cross-sectional view of an exemplary fourth scannable temporary abutment 20 along the cutting line DD shown in Figure 5B. As seen in Figure 5D, the exemplary scannable temporary abutment 20 is hollow, including having a through hole 25. The through hole 25 may extend from the upper end 11 of the scannable member 10 to the base end 21A of the scannable temporary abutment 20. The through hole 25 may be configured to receive a screw for fixing the scannable temporary abutment 20 to a dental implant. The through hole 25 may have a first section 25A having a first diameter, a second section 25B having a second diameter, and a third section 25C having a third diameter. The first section 25A of the through hole 25 may be located in the base section 21 of the temporary abutment 20 and may be configured to receive a dental implant. A third section 25C of the through-hole 25 may extend from the upper end 11 of the scannable member 10 to an intermediate section 22 of the scannable temporary abutment 20. The third section 25C may be configured to receive a screw and a screwdriver for tightening the screw. A second section 25B of the through-hole 25 may be located between the first section 25A and the third section 25C of the through-hole 25. The second section 25B of the through-hole 25 may have a smaller diameter than the first section 25A and the third section 25C of the through-hole, so that the contact surface 26 for the screw inserted into the third section 25C of the through-hole 25 is created by the material surrounding the second section 25B of the through-hole 25. When the screw is tightened into the dental implant, the screw exerts a force on the contact surface 26 that secures the scannable temporary abutment 20 to the dental implant.

[0074] The scannable temporary abutment 20 and the integrated scannable member 10 can be made of a metal or metal alloy, such as titanium or a titanium alloy. In one or more exemplary scannable temporary abutments, titanium may be surface-treated to increase its roughness. Increasing the material roughness can make the scannable temporary abutment 20 scannable and / or improve its scannability. Surface treatment of the scannable temporary abutment 20 and / or scannable member 10 can reduce the reflectivity of the metal surface. The surface of the scannable temporary abutment 20 and / or scannable member 10 may be treated to reduce surface reflectivity, such as surface light reflectivity. The surface of the scannable temporary abutment 20 and / or scannable member 10 can be treated by etching, for example, using an etching method. Therefore, in one or more exemplary scannable members, the scannable temporary abutment 20 and / or scannable member 10 include an etched surface. This reduces reflected light from the scanner, which could otherwise negatively affect the scanning results and prevent the scanner from providing an accurate image of the object being scanned. When smoothing a metal surface, light from the scanner may be reflected off the metal surface, potentially preventing the scanner from creating an accurate image of the object being scanned.

[0075] In one or more exemplary scannable temporary abutments, the scannable temporary abutment 20, such as an assembly of the temporary abutment 20 and the scannable member 10, has a length L in the range of 5 to 14 mm. STAThe scanning temporary abutment 20 may have a length such that the scanning member 10 protrudes above the temporary prosthesis when the temporary prosthesis is fixed to the dental implant via the temporary abutment. The scanning member 10 may have a diameter D1 in the range of 4.0 to 4.8 mm, for example, in the range of 4.2 to 4.6 mm, and a length L in the range of 2.4 to 5.2 mm. Although not disclosed in Figures 5A to 5F, the integrated scanning member 10 may also include a position indicator 15, as disclosed in Figures 4A to 4E, in one or more exemplary scanning temporary abutments 20.

The exemplary scannable temporary abutments 20 shown in Figures 6A to 6D correspond to the scannable temporary abutments 20 shown in Figures 5A to 5F, except that the scannable member is not an integral part of the scannable temporary abutment 20. The upper end 23 of the exemplary scannable temporary abutments 20 in Figures 6A to 6D is instead configured to receive and / or secure one of the exemplary scannable members shown in Figures 2A to 4E. The exemplary scannable temporary abutments 20 may be configured to receive and / or secure the scannable member 10 by clipping or screwing it to the scannable temporary abutment 20. The scannable member 10 may be inserted into a third section 25C of a through hole 25 of a scannable temporary abutment 20 and may be secured by a screw and / or a shape fit of a first projection and / or a plurality of fins that engage with the inside of the through hole 25. In one or more exemplary scannable temporary abutments, the inner surface of the through hole 25 is provided with threads configured to engage with a screw for securing the scannable member 10 to the scannable temporary abutment 20 and / or threads configured to engage with threads provided on the scannable member 10. The scannable member 10 may, for example, have external threads, and the scannable temporary abutment 20 may have internal threads configured to receive the external threads of the scannable member 10. Correspondingly, in one or more exemplary scannable temporary abutments 20, the scannable member 10 may have internal threads, and the scannable temporary abutment 20 may have external threads configured to receive the internal threads of the scannable member 10.

[0077] In one or more exemplary scannable temporary abutments, the scannable temporary abutment 20 includes a magnet configured to engage with a magnet positioned on the scannable member 10 for securing the scannable member 10 to the scannable temporary abutment 20. The magnet of the scannable temporary abutment 20 has opposite poles to the magnet positioned on the scannable member 10, thereby allowing the scannable member 10 to be attracted to and secured to the scannable temporary abutment 20.

[0078] Figures 7A–7C show a kit comprising a scannable member 10 and a screw 30. The scannable member 10 may be clipped onto the screw 30, such as on top of the screw 30. The scannable member 10 may be, for example, the scannable member 10 shown in Figures 2A–2C, 3A–3E and / or Figures 4A–4E. A through-hole 14 extending through the center of the scannable member 10 can provide access to a screwdriver. Thus, a screwdriver can access the screw 30, for example, the screw head 31, through the hole at the top of the scannable member 10 to fasten the screw to and / or unfasten the screw from the scannable temporary abutment 20. In one or more exemplary kits, the kit may also comprise a scannable temporary abutment 20.
