Description

TECHNICAL FIELD

The present technology relates to dental appliances for treating teeth and associated systems and methods.

BACKGROUND

A common objective in orthodontics is to move a patient's teeth to positions where the teeth function optimally and aesthetically. To move the teeth, the orthodontist may begin by obtaining multiple scans and/or impressions of the patient's teeth to determine a series of corrective paths between the initial positions of the teeth and the desired ending positions. The orthodontist then fits the patient to one of two main appliance types: braces or aligners.

Traditional braces consist of brackets and an archwire placed across a front side of the teeth, with elastic ties or ligature wires to secure the archwire to the brackets. In some cases self-ligating brackets may be used in lieu of ties or wires. The shape and stiffness of the archwire as well as the archwire-bracket interaction governs the forces applied to the teeth and thus the direction and degree of tooth movement. To exert a desired force on the teeth, the orthodontist often manually bends the archwire. The orthodontist monitors the patient's progress through regular appointments, during which the orthodontist visually assesses the progress of the treatment and makes manual adjustments to the archwire (such as new bends) and/or replaces or repositions brackets. The adjustment process is both time consuming and tedious for the patient and more often than not results in patient discomfort for several days following the appointment. Moreover, braces are not aesthetically pleasing and make brushing, flossing, and other dental hygiene procedures difficult.

Aligners comprise clear, removable, polymeric shells having cavities shaped to receive and reposition teeth to produce a final tooth arrangement. Aligners offer patients significantly improved aesthetics over braces. Aligners do not require the orthodontists to bend wires or reposition brackets and are generally more comfortable than braces. However, unlike braces, aligners cannot effectively treat all malocclusions. Certain tooth repositioning steps, such as extrusion, translation, and certain rotations, can be difficult or impossible to achieve with aligners. Moreover, because the aligners are removable, success of treatment is highly dependent on patient compliance, which can be unpredictable and inconsistent.

Lingual braces are an alternative to aligners and traditional (buccal) braces and have been gaining popularity in recent years. Two examples of existing lingual braces are the Incognito™ Appliance System (3M United States) and INBRACE® (Swift Health Systems, Irvine, California, USA), each of which consists of brackets and an archwire placed on the lingual, or tongue side, of the teeth. In contrast to traditional braces, lingual braces are virtually invisible, and, unlike aligners, lingual braces are fixed to the patient's teeth and force compliance. These existing lingual technologies, however, also come with several disadvantages. Most notably, conventional lingual appliances still rely on a bracket-archwire system to move the teeth, thus requiring multiple office visits and painful adjustments. For example, lingual technologies have a relatively short inter-bracket distance, which generally makes compliance of the archwire stiffer. As a result, the overall lingual appliance is more sensitive to archwire adjustments and causes more pain for the patient. Moreover, the lingual surfaces of the appliance can irritate the tongue and impact speech, and make the appliance difficult to clean.

Therefore, a need exists for improved orthodontic appliances.

II. Installation Units

Various embodiments of the present technology comprise orthodontic devices, such as installation units, configured to facilitate installation of an orthodontic appliance, one or more brackets, and/or a platform in a patient's mouth. In some embodiments, the present technology comprises an installation unit configured to hold an orthodontic appliance, brackets, and/or a platform in a desired position and/or orientation relative to the patient's teeth during installation of the orthodontic appliance, brackets, and/or platform. Unlike conventional indirect bonding trays (IDBs) that guide installation of brackets only, the installation units of the present technology are configured to support simultaneous installation of two or more of an orthodontic appliance, brackets, and a platform. Various examples of installation units of the present technology are described with regard to FIGS. 2A-7B.

FIGS. 2A and 2B are top and bottom views of an installation unit 200 of the present technology, shown coupled to an orthodontic appliance 250. The installation unit 200 is configured to temporarily hold the orthodontic appliance 250 in a desired position relative to the patient's dentition during installation of the orthodontic appliance 250. As shown, the installation unit 200 may comprise a body portion 202 and a plurality of connection portions 204 carried by the body portion 202 and configured to detachably couple to the orthodontic appliance 250. In some embodiments the connection portions 204 comprise grooves or recesses in the body portion 202. Additionally or alternatively, the connection portions 204 may comprise arms extending away from the body portion 202. The installation units described herein may be configured of any suitable material including, but not limited to a plastic, a rubber, a metal, a composite material, or the like, or combinations thereof. The installation units may be formed by any suitable manufacturing process including, but not limited to molding, 3D printing, machining, and others.

The body portion 202 is configured to be temporarily secured to one or more of the patient's teeth during installation of the orthodontic appliance 250. In some embodiments, the body portion 202 is configured to fit onto one or more (or a plurality of) teeth in a patient's jaw (an upper jaw or a lower jaw). In certain examples, the body portion 202 may have a shape that corresponds to the entire set of teeth in one of the patient's jaws. For example, the body portion 202 may have an arch shape (or partial arch shape) of an intraoral scan or a dental impression formed of the patient's jaw. Accordingly, the body portion 202 may include a recess 208 (visible in FIG. 2B) for receiving all or a portion of one or more (or all) of the teeth in a patient's jaw, when installed, so that the installation unit 200 may be secured relative to a patient's jaw. In particular examples, the body portion 202 is formed from an actual impression or computer rendition of the patient's teeth, so that the body portion 202 fits the patient's teeth in a customized manner. In other examples, the body portion 202 may be configured to fit a plurality of patients (and not customized for a particular patient). For example, various installation unit sizes can be made, to fit a large portion of the public, without requiring a customized body portion 202 for each patient.

The connection portions 204 may be integral with the body portion 202 or may be separate components that are coupled to the body portion. The connection portions 204 may comprise one or more hooks, tabs, fingers or the like, located or extending along the inward-facing surface of the arch shape (for installing an appliance on the inner or lingual surface of a patient's teeth). In other examples, the body portion 202 of the installation unit 200 may include a similar plurality of connection portions (such as, but not limited to hooks, tabs, fingers or the like) located or extending along the outward-facing surface of the arch shape (for installing an appliance on the outer or buccal surface of a patient's teeth).

In some embodiments, the connection portions 204 are configured for retaining temporary wire or tie members 206 that temporarily secure the appliance 250 to the body portion 202 of the installation unit 200. In other examples, the connection portions 204 may be configured with slots or receptacles to receive and temporarily retain brackets and/or arms or other portions of the appliance in a friction fit or snap fitting arrangement. For example, the installation unit 200 may be configured with a plurality of connection portions 204 corresponding in number to the number of arms extending from the rigid bar of the appliance 250 (or corresponding in number to the number of bracket connectors on the appliance 250). As shown in FIG. 2A, the appliance 250 may be coupled to the installation unit 200, by a plurality of wires or ties 206, where each wire or tie 206 couples an arm or a bracket connector of the appliance 250 to a respective one of the connection portions 204 of the installation unit 200 (for example, by twisting or tying the wire or tie around or through the arm or bracket connector and around or through the connection portion). In this manner, the appliance 250 may be held by the installation unit 200, during an installation procedure (for installing the appliance onto a patient's teeth).

More specifically, an installation process may include forming or selecting an appliance 250 and forming or selecting an installation unit 200 to correspond to the patient's teeth in that jaw (for example, to match an impression of a patient's teeth) and to correspond to an appliance. After forming the appliance 250, each of the bracket connectors on the appliance may be connected to a corresponding bracket. In addition, the appliance (with the brackets connected) may be secured to the connection portions 204 of the installation unit 200, by wire ties (or other suitable tie structure, or other temporary connection mechanism). The appliance may be secured to the connection portions 204 directly, or indirectly via securement of the brackets to the connection portions 204. Then, the installation unit 200 (with the appliance 250 and brackets attached) can be fitted (placed) on a patient's teeth. In certain examples, the arms of the appliance 250 extend through slots or gaps between adjacent connection portions 204 (such as, but not limited to between hooks, tabs, fingers or the like), located or extending along the arch shape, such that the brackets that are already connected with bracket connectors on the appliance arms are arranged adjacent respective teeth, when the installation unit 200 is fitted (placed) on the patient's teeth. Then, the brackets may be bonded to respective teeth, while the installation unit 200 (holding the appliance 250) is on the patient's teeth. Once the brackets are bonded to the patient's teeth, the appliance 250 may be freed from the installation unit 200 (for example, by untying or cutting the wire or ties), and the installation unit 200 may be removed, while leaving the appliance 250 connected to the brackets in place on the patient's teeth.

In particular examples, the appliance 250 is secured to the installation unit 200 at a position that locates the appliance 250 at its proper installation location on the patient's jaw, when the installation unit 200 is fitted onto the patient's teeth (and the teeth are received within the recess 202a). Therefore, once the installation unit 200 (with the appliance 250 attached) is placed on the patient's teeth, the appliance 250 is automatically aligned with the patient's teeth, in a position for connecting to the brackets on the patient's teeth. In several embodiments, including any of the installation unit embodiments discloses herein, the installation unit is configured to retain an orthodontic appliance while the orthodontic appliance is in an OTA. As such, when the installation unit is removed from the patient's mouth after the orthodontic device is secured to the patient's teeth, the orthodontic appliance immediately applies a repositioning force to the teeth.

In other examples, the installation unit 200 may be used to install the appliance, after the brackets have been bonded to the patient's teeth. In such examples, the appliance 250 is secured to the installation unit 200 (by wire, other tie structures, or other temporary connection mechanism as described herein). In addition, each bracket is bonded to a respective tooth. Then, the installation unit 200 (with the appliance secured thereto) is placed or fitted onto the patient's teeth. The bracket connector elements on the appliance are then secured to the brackets and the wire, ties or other temporary connection mechanisms are released or removed, to release the appliance from the installation unit 200, while the appliance 250 is secured to the patient's teeth. Then, the installation unit 200 may be removed (slipped off of the patient's teeth), while the appliance 250 remains connected to the patient's teeth.

FIG. 3A is a top view of an installation unit 300 configured in accordance with several embodiments of the present technology, shown secured to an orthodontic device and positioned on a model of a patient's lower jaw. The installation unit and orthodontic device, as assembled, are referred to herein as an “installation unit assembly.” In FIG. 3A, the orthodontic device comprises an orthodontic assembly (i.e., orthodontic appliance 350 coupled to brackets) coupled to a platform 360. Additionally or alternatively, as discussed herein, the installation unit 300 may be configured to hold or facilitate installment of other orthodontic devices.

FIGS. 3B, 3C, 3D, and 3E are top, bottom, top right, and top left views, respectively, of the installation unit assembly shown in FIG. 3A. The platform 360 may be configured to engage or secure an orthodontic appliance (such as orthodontic appliance 350) to a maxilla or a mandible bone of a patient. As shown in FIGS. 3B-3E, for example, the appliance 350 includes platform connection arms 352 configured to be selectively coupled to a platform (such as platform 360). In some embodiments, the platform 360 comprises an annular body 361, one or more anchorage device connector elements 362, and one or more appliance connector elements 364.

In other examples, some or all of the anchorage device connector elements may extend outward, or one or more of the appliance connector elements may extend inward, relative to the annular shape of the body.

Each of the anchorage device connector elements 362 is configured to hold a permanent anchorage device or a temporary anchorage device (TAD). In certain examples, the anchorage device connector elements 362 may correspond to the TAD holders described in U.S. patent application Ser. No. 15/370,704 (Publ. No. 2017/0156823) (for example, at reference numbers 812, 904 or 1012 in that application). The anchorage device connector elements 362 allow a clinician to secure the annular body 361 of the platform 360 to a patient's palate using one or more anchoring devices such as, but not limited to screws, TADs or other suitable anchorage device that extend into the patient's palate (soft and hard tissue). In certain examples, each anchorage device connector element 362 may have an opening (e.g., an opening in an annular extension) through which a screw, TAD or other anchor device may extend. In other examples, other suitable anchorage device connector element configurations may be employed for receiving or holding a screw, TAD or other anchor device.

Each of the appliance connector elements 364 of the platform 360 is configured to be selectively connected with a respective platform connection arm on an appliance (such as arms 352 of orthodontic appliance 350). Each appliance connector element 364 may have a configuration corresponding to any of the brackets (or female connector elements) described herein or in U.S. patent application Ser. No. 15/370,704 (Publ. No. 2017/0156823). Each platform connection arm 352 may have a configuration corresponding to any of the bracket connectors (or male connector elements) described herein or in U.S. patent application Ser. No. 15/370,704 (Publ. No. 2017/0156823). In some examples, each appliance connector element 364 and each platform connection arm 352 may have any other suitable configuration for selectively connecting and disconnecting from each other.

In some embodiments, the recess has a shape configured to substantially conform to at least an occlusal surface of the one or more teeth. The individual shells may be coupled to one another by a plurality of bridges 312, each extending between adjacent shells. In some instances it may be preferable to have individual shells and/or retention portions for each of the teeth being engaged by the installation unit and that are connected by narrow bridges. Such a configuration requires less material and covers less of the patient's mouth than a larger shell that covers more of the patient's teeth and gingiva (for example as shown in FIGS. 2A and 4A), thus improving visibility of the patient's mouth and dentition for the clinician. In some embodiments, the retention portion 314 may have other suitable configurations, such as one or more bands configured to fit over the one or more reference teeth. In some embodiments, the retention portion comprises an arch or partial arch shape corresponding to a dental impression of the patient's jaw. In particular examples, the retention portion 314 (whether a plurality of discrete portions or a continuous member) is formed from an actual impression or computer rendition of the patient's teeth, so that the retention portion 314 fits the patient's teeth in a customized manner. In other examples, the retention portion 314 may be configured to fit a plurality of patients (and not customized for a particular patient). For example, various installation unit sizes can be made, to fit a large portion of the public, without requiring a customized retention portion 314 for each patient.

The first connection portions 304 are configured to detachably couple to a bracket and/or an orthodontic appliance, such as orthodontic appliance 350, to hold and retain the appliance 350 in place relative to the patient's jaw during installation of the appliance 350.
