The present disclosure relates to dental prosthetic devices and, more particularly, to a dental implant or portion thereof, and other dental prosthetic devices, including one or more sensors for monitoring the dental implant, the portion of the dental implant, or the other dental prosthetic device.
Dental implants 10 are typically simple, non-electronic devices, including an anchor portion 20 (in some instances, comprising two or more components such as a screw portion and an abutment received by the screw portion) made of titanium or some other standard biocompatible material, and a prosthetic portion 30 (e.g., a crown) received by the anchor portion 20 (or the abutment component thereof) made of metal (such as stainless steel, gold, or an alloy), porcelain-fused-to-metal, a resin, or a ceramic (see, e.g.,
The implanted dental implant may also be subjected to various forces during the service life of the implant. For example, the dental implant may experience forces from chewing, grinding/bruxation at night, jaw clenching, etc. In some instances, the magnitude of the force(s) may damage the dental implant (the prosthetic portion, the anchor portion, the interface between the anchor portion and the prosthetic portion and/or the interface between the anchor portion and the jawbone). In other instances, repeated cycles of force(s) of a certain magnitude may lead to fatigue damage to the prosthetic portion, the anchor portion, the interface between the anchor portion and the prosthetic portion, and/or the interface between the anchor portion and the jawbone. In instances of damage to the implanted dental implant, remedying of the damage often involves entire replacement of the dental implant.
As such, there exists a need for a dental implant capable of indicating whether the dental implant has been properly implanted in the patient's jawbone, and whether the patient's jawbone has accepted and properly osseointegrated the anchor portion. Moreover, there exists a need for a dental implant capable of indicating the various force(s) experienced by the dental implant in service such that possible damage to the dental implant can be investigated and remedied prior to failure. In addition, there exists a need for dental implant capable of monitoring force(s) and force cycle(s) experienced by the dental implant such that remedial action before failure can be taken prior to the dental implant reaching fatigue limits or end of service life.
The above and other needs are met by aspects of the present disclosure which includes, without limitation, the following example embodiments and, in one particular aspect, provides a dental prosthetic device, comprising an anchor portion and a sensor device arranged to be engaged with the anchor portion.

These and other features, aspects, and advantages of the present disclosure will be apparent from a reading of the following detailed description together with the accompanying drawings, which are briefly described below. The present disclosure includes any combination of two, three, four, or more features or elements set forth in this disclosure, regardless of whether such features or elements are expressly combined or otherwise recited in a specific embodiment description herein. This disclosure is intended to be read holistically such that any separable features or elements of the disclosure, in any of its aspects and embodiments, should be viewed as intended, namely to be combinable, unless the context of the disclosure clearly dictates otherwise.
It will be appreciated that the summary herein is provided merely for purposes of summarizing some example aspects so as to provide a basic understanding of the disclosure. As such, it will be appreciated that the above described example aspects are merely examples and should not be construed to narrow the scope or spirit of the disclosure in any way. It will be appreciated that the scope of the disclosure encompasses many potential aspects, some of which will be further described below, in addition to those herein summarized. Further, other aspects and advantages of such aspects disclosed herein will become apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the described aspects.
Having thus described the disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all aspects of the disclosure are shown. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the aspects set forth herein; rather, these aspects are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
In some aspects, the sensor device 400 is, for example, a force sensor. In particular aspects, the force sensor is disposed between the anchor portion 200 and the prosthetic portion 300, within the prosthetic portion 300, or on a surface of the prosthetic portion 300. In such arrangements, the force sensor is arranged to measure a force imparted to the prosthetic portion 300, whether the force is imparted to the surface thereof, through the body of the prosthetic portion 300, to the interface between the prosthetic portion 300 and the anchor portion 200, or to the anchor portion 200 by way of the prosthetic portion 300. In other aspects, the sensor device 400, in the configuration of a force sensor, is engaged with the anchor portion 200 and arranged to measure a force imparted to the anchor portion 200.
In some instances, the anchor portion 200 defines external threads adapted to threadedly engage a structure such as, for example, the jaw of the patient in a previously-formed borehole. In such instances, the force sensor 420 is engaged with or is otherwise in communication with the external threads and is arranged to measure a threading force engaging the anchor portion 200 with the structure. Such an arrangement can measure, for example, whether the anchor portion 200 is securely seated in the jawbone upon being implanted, whether the anchor portion 200 is progressing toward or has attained suitable osseintegration with the jawbone, and/or whether the threads of the anchor portion 200 have loosened or otherwise may be indicating an endpoint of service life.
In other instances, in addition to or in an alternative to the force sensor 420 engaged with the external threads of the anchor portion 200, the anchor portion 200 may be arranged to include a wall 430 defining an internal channel (e.g., an internal hollow channel extending along the length of the anchor portion 200), and a force sensor 440 can be arranged to be engaged with the wall 430 within the internal channel and is further arranged to measure forces imparted to the anchor portion 200. A force sensor 440 arranged in this manner may indicate, for example, a bending moment exerted on the anchor portion 200.
In some aspects, the sensor device 400 is a contact sensor 460 (e.g., a force sensor, a pressure sensor, a touch sensor, and/or suitable surface sensor) engaged with a surface of the prosthetic portion 300 and is arranged to sense external contact with the prosthetic portion 300. A contact sensor 460 arranged in such a manner on a surface of the prosthetic portion 300 can indicate, for example, locations of occlusion across the surface that allows the prosthetic portion 300 to be adjusted, re-shaped, etc. in order to minimize or eliminate the localized occlusion.
In other aspects, the sensor device 400 is a force sensor or a contact sensor 480 engaged with the anchor portion 200 or the prosthetic portion 300, or otherwise disposed between the anchor portion 200 and the prosthetic portion 300. The force/contact sensor 480 arranged in this manner can indicate, for example, the security of the connection between the anchor portion 200 and the prosthetic portion 300, force(s) experienced by the anchor portion 200 by way of the prosthetic portion 300, and/or the number of times that a threshold force is experienced by the anchor portion 200 and/or the prosthetic portion 300 by way of force(s) experienced by the prosthetic portion 300.
In some aspects, the dental prosthetic device 100 further comprises a power source 500 arranged in electrical communication with the sensor device 400, and disposed within the anchor portion 200. In other aspects, particularly where the dental prosthetic device 100 comprises the anchor portion 200 and the prosthetic portion 300, the power source 500 is arranged in electrical communication with the sensor device 400, and disposed within the anchor portion 200, within the prosthetic portion 300, or between the anchor portion 200 and the prosthetic portion 300. In particular instances, the power source 500 is configured and arranged to as to have an extended service life, or to be capable of generating electrical power, without the power source 500 requiring recharging from an external source or without replacement of the power source 500 in the dental prosthetic device 100. For example, in such instances, the power source 500 can be arranged to generate electrical power in response to vibration or movement (e.g., while the patient is chewing). In other instances, the power source 500 can include a battery 520, as well as a charging device 540 in electrical communication with and configured to charge/recharge the battery 520, wherein the charging device 540 may be configured and arranged to generate electrical power for charging/recharging the battery 520, in response to vibration or movement. The power source 500 is therefore arranged to provide electrical power at least to the sensor device 400.
In other aspects, the dental prosthetic device 100 can include at least a transmitter 600 in communication with the sensor device 400 and with the power source 500. In particular instances, the transmitter 600 is housed by or otherwise engaged with the anchor portion 200. In other instances, the transmitter 600 is housed by or otherwise engaged with the anchor portion 200, with the prosthetic portion 300, or between the anchor portion 200 and the prosthetic portion 300. In such instances, the transmitter 600 is arranged to transmit data collected from the sensor device 400 away from the dental prosthetic device 100. For example, the data can be transmitted from the dental prosthetic device 100 to a receiver 700 at a discrete/separate analysis station such that the data can be analyzed in regard to parameter(s) sensed by the particular type(s) of sensor(s) included in the sensor device 400. For example, the transmitter 600 can be configured and arranged to transmit the data via Bluetooth, Near-Field Communication (NFC), WiFi, or any other suitable wireless or contactless communication method, wherein the communication with the receiver 700 requires the receiver 700 to be appropriately configured to communicate with the transmitter 600 and receive the data therefrom.
In some aspects, the transmitter 600 is configured to implement a communication modality such as, for example, NFC, inductive data transmission, electromagnetic data transmission, ultrasonic data transmission, or other suitable protocol, wherein the transmitter 600 is electrically powered or is active on a limited basis (e.g., on demand or at selected time intervals) in order to reduce power requirements. For example, the transmitter 600 configured for NFC data transmission can normally be in sleep mode or otherwise in a dormant state (e.g., not transmitting data and not otherwise consuming power from the power source 500). However, when brought into proximity to a receiver 700 similarly configured for NFC and to initiate contactless communication (e.g., a contactless communication modality) therebetween, the proximity between the transmitter 600 and the receiver 700 wakens or otherwise activates the transmitter 600 for the receiver 700 to capture sensor data therefrom, thereby reducing, minimizing, or eliminating the power requirement for the transmitter 600 from the power source 500.
Moreover, the receiver 700 at the analysis station can be arranged and configured, for example, in conjunction with an application running on a mobile device, or a suitable computer program product executed on a computer device having a processor and a memory storing executable instructions executable by the processor for performing the data analysis. Based on the parameter(s) being monitored by the sensor device 400, the application on the mobile device and/or the computer program product on the computer device can be arranged/configured to actuate an alarm or other suitable warning if a parameter sensed by the sensor device 400 is outside of threshold limit(s) such that appropriate remedial action can be taken (e.g., an alert can be actuated in the event of the anchor portion 200 loosening in the jawbone, or when an incident of concern (e.g., excessive force sensed) has been detected).
In some instances, the dental prosthetic device 100 according to various aspects may further include a receiver 650 in addition to the transmitter 600, wherein the receiver 650 may be configured and arranged to receive incoming signals, for example, for actuating various components within the dental prosthetic device 100. For example, in some aspects, a reservoir 800 is arranged to contain a medicament, and a dispensing device 900 is arranged in communication with the reservoir 800 and arranged and configured to dispense the medicament from the reservoir 800 away from the dental prosthetic device 100. The reservoir 800 and the dispensing device 900 can be disposed within the anchor portion 200. In other aspects where the dental prosthetic device 100 includes a prosthetic portion 300, each of the reservoir 800 and the dispensing device 900 can be disposed within the anchor portion 200, within the prosthetic portion 300, or between the prosthetic portion 300 and the anchor portion 200. In such an arrangement, the dispensing device 900 can be arranged in communication with the receiver 650, and to be responsive to an actuation signal received via the receiver 650 to release the medicament from the reservoir 800 and outwardly of the dental prosthetic device 100. For example, the medicament can be released from the reservoir 800 into the patient's bloodstream upon the dispensing device 900 receiving an actuation signal via the receiver 650. In some instances, instead of or in addition to a medicament, the reservoir 800 can contain, for example, nanoscale bioelectronics which can be released into the patient's bloodstream, as necessary, so as to facilitate, for example, blood analysis (e.g., cancer screening) or other biological/chemical function.
In other aspects, the dental prosthetic device 100 can include a controller 1000 instead of or in addition to the receiver 650. The controller 1000 can include a timer, appropriate logic, or communication provisions with the receiver to generate an actuation signal to the dispensing device 900 for releasing the medicament, bioelectronics, and/or other substance (e.g., an anesthetic) into the patient's bloodstream. In some instances, the controller 1000 is arranged and configured to receive and analyze data from the sensor device 400, and then to take appropriate action based upon the data analysis or to then transmit the data and/or analysis of that data outwardly of the dental prosthetic device 100 via the transmitter 600.
Another aspect of the present disclosure is directed to a method of forming a dental prosthetic device having a prosthetic portion arranged to be engageable with an anchor portion. Such a method comprises, for example, engaging a sensor device with an anchor portion of the dental prosthetic. In other aspects, such a method comprises engaging a sensor device with an anchor portion of the dental prosthetic, with the prosthetic portion of the dental prosthetic, or between the prosthetic portion engaged with the anchor portion. Other method aspects associated with the forming of such a dental prosthetic device are readily evident from the disclosure of such a device as otherwise provided herein.
In light of ever-increasing miniaturization of various sensors (e.g., force-measuring film sensors) and other electronic components, aspects of the present disclosure provide an enhanced dental implant/prosthetic device that incorporates these miniaturized sensors and other miniaturized electronic components into the device so as to provide an active, “intelligent” device capable or sensing, monitoring, analyzing, and remedying conditions that can occur during the service life of the device.
Aspects of the dental prosthetic device according to the disclosure are thus capable of indicating whether the dental implant has been properly implanted in the patient's jawbone, and whether the patient's jawbone has accepted and properly osseointegrated the anchor portion. Other aspects of the dental prosthetic device are also capable of indicating the various force(s) experienced by the dental implant in service such that possible damage to the dental implant can be investigated and remedied prior to failure, and allow for the monitoring force(s) and force cycle(s) experienced by the dental implant such that remedial action before failure can be taken prior to the dental implant reaching fatigue limits or end of service life.
