Although advances have been made in recent years for the treatment of specific dental diseases, the actual delivery of dental treatment remains a manually intensive process. Accordingly, there is a need for methodology for automating dental treatment.
The existing dental treatment apparatuses or systems are unable to achieve automated dental treatment, e.g., automated tooth cutting. The existing apparatuses or systems rely on vision systems (e.g., human vision, real-time images of the teeth) for carrying out dental treatment, and there are major technical challenge(s) and regulatory risk(s) associated with automation of the vision-based dental treatment methods. Further, automation attempts utilizing expensive robotic arms can put the price point to above $100K for the dental treatment system(s) and are unlikely to be approved for full automation by the FDA due to the large working envelope in which its arms could cause damage. Thus, there is an urgent and unmet need for automating dental treatment with cost-effective, safe, and reliable apparatuses and systems. Also, one of the applications herein is to cut the teeth for crowns (cutting teeth themselves), not for dental drilling in surgery (drilling bore holes into bone for dental implants).The present disclosure relates to apparatuses, systems and methods for automating dental treatment.

Unlike existing systems and methods for dental surgery locating, the systems and methods here eliminate the need for fiducial tracking through optical means and rely on mechanical coupling mechanism(s) for accurate, reliable, and efficient dental positioning, e.g., identical positioning of teeth relative to the system for dental treatment during two different patient visits. In some embodiments, the tooth clamp herein provide anchoring for irrigation and/or suction apparatuses that are also used in automated dental treatment.

The novel features of the disclosure are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present disclosure will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the disclosure are utilized, and the accompanying drawings of which:
Many existing dental treatment apparatuses and systems are not capable of automated dental treatment, e.g., automated tooth cutting. Existing apparatuses and systems experience a major technical challenge and regulatory risks rely towards automated dental treatment due to the large working envelope of possible damage. Thus, there is an urgent and unmet need for automating dental treatment with cost-effective, safe, and reliable apparatuses and systems. As such, provided herein, are devices and systems for cutting teeth for crowns or dental drilling in surgery. The present disclosure relates to apparatuses, systems and methods for automating dental treatment.
In some embodiments, the present disclosure herein includes a tooth clamp which connects a computer numerical control (CNC) directed system to one or more teeth of the subject. In some embodiments, the tooth clamps disclosed herein are fabricated based on surface data of teeth of the subject. In some embodiments, the tooth clamp includes a specifically fabricated surface that mates to the surface of the tooth of the subject. Such a tooth clamp acts to retain teeth, protect soft tissue of the subject, provide positional reference to the CNC, and provide an identical positional environment of the teeth relative to the CNC at different time points. Unlike existing systems and methods for dental surgery locating, the systems and methods here eliminate the need for fiducial tracking through optical means by relying on mechanical coupling mechanism(s) for accurate, reliable, and efficient dental positioning, e.g., identical positioning of teeth in two different visits relative to the system for dental treatment. In some embodiments, the tooth clamp herein provide anchoring for irrigation and/or suction apparatuses that are also used in automated dental treatment. In some embodiments, the apparatus, systems, and methods herein includes dental adhesives, irrigation, suction, protection of the soft tissue that can work in combination with the tooth clamp or alone by themselves to facilitate automated dental treatment.
Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
As used herein, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Any reference to “or” herein is intended to encompass “and/or” unless otherwise stated.
As used herein, the term “about” refers to an amount that is near the stated amount by 10%, 5%, or 1%, including increments therein.
The term “subject” as used herein refers to a human patient in need of dental treatment or a human control subject.
As used herein, the term “about” in reference to a percentage refers to an amount that is greater or less the stated percentage by 10%, 5%, or 1%, including increments therein.
As used herein, the phrases “at least one”, “one or more”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B, or C” and “A, B, and/or C” means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.

Further, per
In some embodiments, the automated dental drill 10 further includes a translational drive assembly 36 which drives end effector 88 along the three or more directions. The translational drive assembly 36 can comprise three or more translational drives that move an end effector 88 in three or more directions: z-direction drive 38, y-direction drive 40, and x-direction drive 42. Each of the z-direction drive 38, the y-direction drive 40, and the x-direction drive 42 can be actuated by a stepper drive, piezoelectric drive, servomotor drive, or any combination thereof. Each of the z-direction drive 38, the y-direction drive 40, and the x-direction drive 42 can be a stepper drive, piezoelectric drive, servomotor drive, or any combination thereof. A coupler 44 can be used to couple the movement of the three translational drives to cutting drive support 18 and end effector 88.
The automated dental drill 10 can also include a clamp connector 46 that attaches to the tooth clamp. The tooth clamp 48 can be attached to a subject's mouth about a tooth to be treated. The clamp connector 46 can be attached to a support system 50 which can be fixed to dental drill housing 12. The clamp 48 can be fabricated from scanned data of the target teeth's position and topography. The clamp 48 can reposition teeth to their original scanned position to correct for relative movement between scanning and clamping when placed on the teeth of the patient prior to cutting a given tooth. The translational drive assembly 36 can be zeroed to the clamp 48 before cutting. The translational drive assembly 36 can be mechanically coupled to the clamp 48 during cutting. In some embodiments, the tooth clamp 48 can be a 3D printed or molded clam-shell structure having internal surfaces that mate with the teeth in an ultrahigh precision fashion. During cutting, the end effector (e.g., the drill or laser) can cut through the plastic of the clamp to access the tooth material beneath. Since several teeth are held simultaneously by the tooth clamp internal surfaces, movement of the teeth is reduced during cutting.
In some embodiments, the automated dental drill 10 further includes a cantilever arm 50 and one or more gimbals 52, 54, 56 that allow passive positioning and support of the automated dental drill. The cantilever arm 50 can be anchored to a support structure 58 (e.g., a wall, cart, ceiling, floor, dental chair, etc.).
In some embodiments, the patient-specific jaws 701A 701B and the first surface 701A 701B are fabricated custom for each patient. In some embodiments, the first surface 701A 701B is generated at least partly based on three-dimensional surface data of one or more teeth of the subject. As a non-limiting example, teeth surface data is provided by a surface scanning system (such as but not limited to a Dentsply Sirona CEREC or Align Technologies intraoral scanning device). This teeth surface information can then be translated into a 3D model of the teeth, with a specific region picked for use based on the procedure (for one tooth or many teeth). In some embodiments, the 3D model of the teeth is then paired digitally with 3D models of standard-sized rigid material (e.g. plastic such as PEEK, Polycarbonate, Acrylic, etc., metal, polymer, etc) (whether a single stock size or a range). The overlap of 3D tooth model and standard-sized pieces can then be locked at a pre-determined position, and a fabrication method can be determined. In some embodiments, the fabrication method includes one or more of: three-dimensional printing, molding, casting, computer numerical control (CNC) machining, and/or machining with a toolpath Such method can be used to create cutaways in the standard sized pieces, and then the patient-specific jaws 701A 701B can be generated after removal of the cutaways. In some embodiment, fabrication of the jaws can be done either at the dental clinic where the diagnostics and treatment take place using in-house fabrication method (e.g., casting, CNC machining, or 3D printing), or alternatively at an external lab or centralized fabrication facility.
In some embodiments, fixation points on the tooth clamp 700 acts to secure a number of suction ports 702. In some embodiments, the suction ports 702 are configured for allowing removal of debris and cooling/flushing water curing or after tooth cutting. In some embodiments, the suction ports functions together with equipment(s) including but not limited to mechanisms to provide negative pressure within. Additional accessories can be added to equipment that provides negative pressure in the dental office. In some embodiments, the accessories include custom end orifices to couple the suction ports 702 to portions of the tooth clamp 700, along with necessary branching mechanisms such that one suction device can be made into several orifices to engage with the tooth clamp. In some embodiments, the suction ports 702 are configured to connect to more than one orifice located at different portions of the clamp. The suction ports can be attached on the one or more frames, the one or more jaws, the one or more teeth of the subject, or a combination thereof In some embodiments, the suction ports include flexible materials such as plastic, polymer, rubber, silicone, or the like. In some embodiments, the tooth clamp 700 includes one or more irrigation orifices. Such irrigation orifices can be located at or close to a distal end (the end that is closer to the subject than a proximal end) of the system configured for a dental procedure. In some embodiments, the one or more irrigation orifices are located to surround a tooth cutting or tooth drilling burr of the system. In some embodiments, the one or more irrigation orifices are located to allow passage of a laser beam used for tooth cutting or tooth drilling. In some embodiments, lasers and water irrigation can be consolidated in a coaxial fashion, whether overlapping or annular in cross section.
In some embodiments, such suction ports are the same as existing dental suction ports. In some embodiments, the irrigation orifices include a cross-section that is substantially circular. In some embodiments, the irrigation orifices include a cross-section that is of any arbitrary geometrical shapes, non-limiting examples of such shapes include oval, diamond, square, star, etc. In some embodiments, such irrigation orifices are the same as existing dental suction ports.
In some embodiments, the frames are of a single standard size or a range of standard sizes to allow for high volume fabrication prior to custom patient-specific jaw fabrication.
In some embodiments, the coupling points on the patient-specific jaws provides fixation of the tooth clamp to the system, e.g., ADD system, such that all degrees of freedom are substantially zero. In some embodiments, relative movement of the tooth clamp to the system during a dental procedure is within that of clinically acceptable thresholds. In some embodiments, the coupling points provides fixation such that the maximal relative movement of the tooth clamp with respect to the system is substantially zero. In some embodiments, such fixation can allow the system to enclose the tooth clamp and ensure that debris is contained within the tooth clamp. In some embodiments, such fixation advantageous allows the suction port 702 to effectively and efficiently remove any rinsed material and excess flushing water. In some embodiments, the system performs a dental treatment or procedure with the tooth clamp attached thereon. For example, the dental drilling head within the ADD can execute a cut to the desired tooth. Once the operation is complete, the ADD can be removed from the tooth clamp, and the tooth clamp can then be removed from the teeth of the patient, allowing the clinician to complete their work on the target tooth/teeth.
In some embodiments, the tooth clamp can be installed onto the teeth through clamping force directed either through screw leverage, material elastic force (analogous to traditional tooth clamp), tensioned band force via screw leverage (see traditional dental band clamp), or any other applicable means to squeeze the two frame/patient-specific jaws in a parallel and opposing fashion, e.g., along the Y-axis, to clamp the exterior of the target region of teeth.
In some embodiments, the tooth clamp is installed onto the teeth through adhesive force using an adhesive applied on the one or more jaws. In some embodiments, the adhesive is at least partly on the first surface. Such adhesive force can be activated by an initial clamping force, squeezing force or the like to allow sufficient contact of the adhesive with the tooth surfaces. The initial force can be removed after the adhesive force has taken place.
In some embodiments, the coupling points, the jaw(s), the frame(s), or a combination thereof includes rigid or semi-rigid material(s). In some embodiments, the rigid material(s) include one or more of: plastic, composite, metal, glass, porcelain, rubber, and alloy. In some embodiments, the rigid material(s) include one or more of: polyether ether ketone (PEEK), polycarbonate, and acrylic.
In some embodiments, the tooth clamp disclosed herein that can be used along with the system for dental procedures allows for a datum to be set for machining. The tooth clamp can act to couple the ADD system's coordinates to that of the dental anatomy, thereby allowing the ADD system to track where it is in reference to the teeth. Therefore, the tooth clamp can allow a common datum to be set between the two systems, a datum can be an origin by which a common (Cartesian, cylindrical, spherical, etc.) coordinate system is set.
In some embodiments, the datum is provided through coupling the system to known points on the frames and tracking known points through the tooth clamp to a known position on a given tooth, within an acceptable tolerance derived from the process of creating the dental clamp. Thus, the one or more jaws can provide positional reference during a dental procedure. In some embodiments, the one or more jaws provide an identical positional environment of the one or more teeth relative to the system at different time points. In some embodiments, this advantageously ensures that as between the time when teeth are scanned and the operation takes place, teeth can move, but the tooth clamp can reposition the teeth to their previously scanned position as the patient-specific jaws are fabricated to match the geometries and positions of the teeth when they are scanned.
As seen in
In some embodiments, the sensors 902 are optical. In some embodiments, the sensors 902 determine the current dimensions of the tooth using machine-vision (image analysis). In some embodiments, the sensors 902 use optical-coherence tomography to determine the current dimensions of the tooth. In some embodiments, the sensors 902 use speckle interferometry to determine the current dimensions of the tooth. In some embodiments, the sensors 902 use ultrasound to determine the current dimensions of the tooth. In some embodiments, the current dimensions of the tooth as determined by the sensors 902 are compared to the surgical plan to determine the progress of the dental procedure.
In some embodiments, the current dimensions of the tooth as determined by the sensors 902 are compared to prior dimensions of the tooth to determine the rate of tissue removal. In some embodiments, the prior dimensions of the tooth are determined using previous measurements by the sensors 902 during the same procedure. In some embodiments, the prior dimensions of the tooth are determined using prior measurements of the tooth performed using other means which will be apparent to those knowledgeable in the art. As a non-limiting example, teeth surface data is provided by a surface scanning system (such as but not limited to a Dentsply Sirona CEREC or Align Technologies intraoral scanning device).
In some embodiments, the current and past dimensions of the tooth are used to control the cutting speed of the automated dental drill (ADD) for optimal tissue removal. In some embodiments, the rate of tissue removal (as determined by current and past dimensions of the tooth) is used to distinguish healthy tissue from unhealthy tissue. As a non-limiting example, dense tooth material will cut or ablate at a lower rate than caries. In some embodiments, the rate of tissue removal (as determined by current and past dimensions of the tooth) is used to distinguish gingiva from tooth. In some embodiments, the spatial distribution of tissue-removal rate is used to determine the extent of tissue to be removed, and determine the progress and completion of the procedure.
In some embodiments, the determination of procedural progress or completion, as determined using the tissue-removal rate, is performed using an automated control system. As a non-limiting example, the automated control system can be implemented using a computer. As another non-limiting example, the automated control system can be implemented using a microcontroller. As a third non-limiting example, the automated control system can be implemented using a Field-Programmable Gate Array (FPGA).
