DENTAL OPTIC DEVICE AND USES THEREOF

CROSS-REFERENCE TO RELATES APPLICATIONS

[0001] This application claims priority benefit to U.S. Provisional Application No. 62/547,355, filed August 18, 2017, and U.S. Provisional Application No. 62/635,258, filed February 26, 2018, the contents of each of which are incorporated by reference herein in their entirety.

TECHNICAL FIELD

[0002] The present invention provides dental devices that attach to at least one tooth or other dental work of a first arch and provide a hands-free intraoperative platform for attachment of, e.g., optical devices. In some aspects, the present invention provides dental optic devices that attach to at least one tooth or other dental work of a first arch and provide hands-free intraoperative

visualization of at least one area of a second arch opposing the first arch. The present invention further provides systems comprising a dental device disclosed herein and methods of performing a dental procedure using such a dental device.

BACKGROUND OF THE INVENTION

[0003] Obtaining the proper intraoperative visualization necessary to perform procedures on posterior dentition of the mandible and maxilla has long been a challenge due to space constraints of the oral cavity and the angles necessary to view certain anatomical features. For example, performing a root canal on a 2^nd or 3^rd molar involves obtaining visualization near the back of the oral cavity as well the deep interior pulp chambers of each root of the molar.

[0004] Methods for obtaining intraoperative visualization of the posterior dentition include altering body postures of both patient and practitioner from a comfortable and/or resting posture, requiring dental practitioners to perform procedures with constrained body posture, and/or indirect visualization through the use of a mirror held by a dental practitioner. These methods may lead to a lack of constant intraoperative visualization of the working area (e.g., surgical area or field), which can extend the length of a procedure and deleteriously impact the ability to precisely conduct the procedure. Furthermore, adjusting the patient's and/or dental practitioner's body posture may lead to discomfort, fatigue, and frustration. For example, dental practitioners frequently strain their necks, backs, and eyes when attempting to visualize the posterior dentition of their patients, which may lead to a shortened dental career.

[0005] Indirect intraoperative visualization through the use of a mirror held by a dental practitioner is a common method for conducting posterior dentition procedures. However, use of a mirror for visualization may block access for tools necessary to conduct a procedure and/or occupy the hand of dental practitioner that could otherwise be used to more effectively conduct the procedure.

[0006] Intraoral camera devices are used in the dental practice to improve oral cavity visualization. For example, wand-type intraoral camera devices are used to view and photograph existing conditions of the oral cavity, but their design does not provide a tool suitable for intraoperative use, and as such their use is generally limited to collection of pre-operative images for patient counseling and/or procedure preparation. See U.S. Patent No. 7,086,859. Other examples of intraoral camera devices include camera/dental tool integration, e.g., a camera attached to a dental drill. See U.S. Patent No. 5,049,070. While such a tool may be useful in providing limited visualization during drilling, it may not provide imaging when the tool is not in use and also may suffer from poor image stability due to operation of the tool as well as concomitant utilization of irrigation during the procedure.

DETAILED DESCRIPTION OF THE INVENTION

[0045] The present invention provides dental devices comprising a first attachment head, a second attachment head, and a connector operable connecting the first attachment head and the second attachment head, wherein the connector is configured so that the first attachment head and the second attachment head contact opposite axial surfaces of at least one tooth in a first arch. In some embodiments, the dental devices of the present invention comprise a first attachment head and/or a second attachment head further comprising a first camera configured to provide visualization of at least a first area of a second arch opposing the first arch. [0046] The dental devices disclosed herein comprise elements for attaching the dental device to at least one tooth or other dental work (e.g., bridges, false teeth) situated in a first dental arch of a patient, thereby providing a stable, self-holding platform, which, in some embodiments, comprises at least one camera, and optionally lighting equipment, for visualization of a second, opposing dental arch. The dental devices disclosed herein may be used for hands-free visualization of a working area (e.g., a surgical area) on or around a dental arch during a dental procedure. Use of the disclosed dental devices may allow dental practitioners, such as dentists, endodontists,

prosthodontists, and other specialists, to maintain constant direct intraoperative visual access of the working area, thus improving the ability to provide effective, efficient, and consistent treatment of the posterior dentition.

[0047] The dental devices of the present invention may be attached to at least one tooth or other dental work situated in either the maxillary and mandibular posterior dentition. For example, visualization of a working area in the maxillary posterior dentition is achieved by attachment of a dental device of the present invention to at least one tooth or other dental work situated in the mandibular posterior dentition. The same dental device may also be placed on at least one tooth or other dental work situated in the maxillary posterior dentition to observe a working area in the mandibular posterior dentition. Furthermore, proper placement of the dental devices of the present invention may provide direct intraoperative visualization of the working area and maximize space for instrumentation access to the working area.

[0048] Dental devices disclosed herein comprising two or more cameras may provide additional video feeds useful for a dental practitioner to more completely observe and assess the working area during a procedure. Systems disclosed herein comprising such a dental device and a viewing device may allow a dental practitioner to simultaneously view all video feeds or toggle between the video feed from each camera in order to achieve maximum visibility of the working area during a procedure. Furthermore, the dental practitioner can obtain still frame photos from video feed(s) from the dental devices.

[0049] Elements of dental devices of the present invention will now be described in more detail, including: (1) elements for attaching a dental device to at least one tooth situated in a first arch; (2) elements for visualization of posterior dentition; and (3) elements for power sourcing and connectivity to the dental device. [0050] In some embodiments described herein, the dental devices of the present invention may be described via angles of various elements, as measured on an imaginary latitudinal perpendicular plane and/or an imaginary longitudinal perpendicular plane, relative to a first imaginary surface of a first imaginary right rectangular prism (see, e.g., FIG. ID). As used herein, an imaginary latitudinal perpendicular plane, e.g. , a first imaginary latitudinal perpendicular plane, refers to a plane that is perpendicular to a first imaginary surface and a second imaginary surface of an imaginary right rectangular prism and perpendicular to a center longitudinal axis of an attachment head of a dental device, wherein the first imaginary surface is substantially parallel with the occlusal surface of the attachment head of the dental device, wherein the first imaginary surface comprises an edge that is parallel with the center longitudinal axis of the attachment head of the dental device, and wherein the imaginary latitudinal perpendicular plane contacts opposite edges of the first imaginary surface and the second imaginary surface at points equidistant from respective edges of the first imaginary surface and the second imaginary surface that are parallel to the imaginary latitudinal perpendicular plane. For imaginary latitudinal perpendicular planes, 0° is in line with the outside edge (e.g. , edge that is away from the axial side of an attachment head) of a first imaginary surface that is parallel with the center longitudinal axis of an attachment head of a dental device and substantially in line with an occlusal side of the attachment head (see, e.g., FIG. ID). As used herein, an imaginary longitudinal perpendicular plane, e.g., a first imaginary longitudinal perpendicular plane, refers to a plane that is perpendicular to a first imaginary surface and a second imaginary surface of an imaginary right rectangular prism and parallel to a center longitudinal axis of an attachment head of a dental device, wherein the first imaginary surface is substantially parallel with the occlusal surface of the attachment head of the dental device, wherein the first imaginary surface comprises an edge that is parallel with the center longitudinal axis of the attachment head of the dental device, and wherein the imaginary longitudinal perpendicular plane contacts opposite edges of the first imaginary surface and the second imaginary surface at points equidistant from respective edges of the first imaginary surface and the second imaginary surface that are parallel to the imaginary longitudinal perpendicular plane. For imaginary longitudinal perpendicular planes, 0° is in line with the front edge (e.g., opposite the side of the attachment head that engages a connector) of first imaginary surface that is perpendicular with the center longitudinal axis of an attachment head of a dental device and substantially in line with an occlusal side of the attachment head (see, e.g., FIG. ID)

In some embodiments, the interproximal fixation element comprises an interproximal contact element, wherein the interproximal contact element is latitudinally situated on a first axial side of a first attachment head, and wherein the interproximal contact element is configured to contact an axial surface of at least one tooth at or near an interproximal surface of the at least one tooth. In some embodiments, the interproximal contact element is a portion of the same material constituting an interproximal fixation element. In some embodiments, the interproximal contact element is a different material than an interproximal fixation element. [0058] In some embodiments, the edge of the interproximal contact element is substantially aligned about -80° to about -120°, such as about -90° to about -120°, about -95° to about -120°, about -95° to about -1 10°, and about -90° to about -100°, as measured on a first imaginary latitudinal perpendicular plane, relative to a first imaginary surface of an imaginary right rectangular prism. In some embodiments, the edge of the interproximal contact element is substantially aligned about -80°, about -85°, about -90°, about -95°, about -100°, about -105°, about -1 10°, about -1 15°, or about -120°, as measured on a first imaginary latitudinal perpendicular plane, relative to a first imaginary surface of an imaginary right rectangular prism.

[0059] In some embodiments, the interproximal contact element comprises a gingival embrasure engagement element, wherein the gingival embrasure engage element is on a distal portion of the interproximal contact element relative to an occlusal side of the first attachment head. In some embodiments, the gingival embrasure engagement element is configured to engage a gingival embrasure. In some embodiments, the gingival embrasure engagement element is the same material as the interproximal contact element. In some embodiments, the gingival embrasure engagement element is the same material as the interproximal fixation element. In some embodiments, the gingival embrasure engagement element is a different material than the interproximal fixation element. In some embodiments, the gingival embrasure engagement element is an antimicrobial material compatible with autoclave sterilization. In some embodiments, the gingival embrasure engagement element is a non-intrusive material that minimizes impingement of gingiva. In some embodiments, the gingival embrasure engagement element is a soft plastic, a silicone, or a rubber.

[0060] In some embodiments, the first attachment head comprises a dentition recess situated on an axial side.

In some embodiments, the first dentition recess and the second dentition recess are configured to follow axial surfaces of at least one tooth in an arch. In some embodiments, the first dentition recess and the second dentition recess are configured to follow axial surfaces of at least two adjacent teeth in an arch.

[0061] In some embodiments, the elements of a first attachment head useful for stabilizing the dental devices of the present invention to at least one tooth situated in a dental arch (e.g. an interproximal fixation element, an interproximal contact element, a gingival embrasure engagement element, a dentition recess) are situated to provide attachment of the dental device to the dental arch and to increase the distance from the occlusal side of the first attachment head to a second dental arch to which the dental device is not attached, relative to the distance from the occlusal surfaces of dentition in the dental arch to which a dental device is attached. In some embodiments, the elements of a first attachment head useful for stabilizing the dental devices of the present invention to at least one tooth situated in a dental arch (e.g. an interproximal fixation element, an

interproximal contact element, a gingival embrasure engagement element, a dentition recess) are situated to provide attachment of the dental device to the dental arch and to place the occlusal side of the first attachment head in line with or below (i.e., more apically situated) the occlusal surfaces of dentition in the dental arch to which a dental device is attached.
