Definitions
- the present invention generally relates to orthodontic appliances, more particularly to a system of orthodontic appliances for the comprehensive treatment of malocclusions, which allows for the application of substantially statically determinate forces and moments to generate controlled and predictable orthodontic correction of a malocclusion.
- Malocclusion of the dentition and jaws are commonly seen in the general population. While the degree or severity may vary from person to person, it is estimated that roughly two out of every three individuals suffer from malocclusions of some type. Malocclusions are generally corrected to improve aesthetics, restore normal oral function, establish improved relationships of the teeth in their bony housing and gum tissue. These measures generally result in better oral health. Malocclusions manifest themselves in three reference planes of space namely the transverse, the vertical and the sagittal plane of space. Some common malocclusions include crowded or misaligned teeth, cross bite, deep bite, open bite, overjet, under bite, etc. Over the years a number of strategies have evolved to treat the malocclusions. For instance, crowding is commonly managed by creating space in the dental arches.
- This may be achieved by extraction of selected teeth or by non-extraction approaches which may involve shaving of teeth, to reduce their size, in order to fit them in the dental arches or expansion of the teeth or advancing the teeth forward or pushing the back teeth further back to create space to correct the crowding.
- Brackets and arch wires and aligners are engaged into bracket slots with the brackets bonded to the teeth, and since they distort elastically, as the arch wires recover to their original shape, they create forces that trigger a biological response to move the teeth.
- These brackets may be placed on the front of the teeth i.e. labial surfaces located on exposed visible surfaces of teeth or lingual surfaces that are located on the back or inner surfaces of teeth. The location of brackets on the teeth and bends in the arch wire determine the magnitude and direction of forces applied on the teeth.
- elastically deformable elements such as coil springs, elastomeric chains may also be deployed at key locations to provide additional forces to move teeth
- Aligners are removable plastic shells that cover the entire surface of teeth and their action is commonly coupled with attachments bonded on teeth. The shells are distorted elastically when they engage the teeth and as they recover their programmed shape they create forces to move teeth.
- U.S. Pat. No. 5,431,562 to Andreiko et al. describes a computerized, appliance-driven approach to orthodontics.
- first certain shape information of teeth is acquired.
- a uniplanar target arch form is calculated from the shape information.
- the shape of customized bracket slots, the bracket base, and the shape of an orthodontic arch-wire, are calculated in accordance with a mathematically-derived target archform.
- the goal of the Andreiko et al. method is to give more predictability, standardization, and certainty to orthodontics by replacing the human element in orthodontic appliance design with a deterministic, mathematical computation of a target archform and appliance design.
- the '562 patent teaches away from an interactive, computer-based system in which the orthodontist remains fully involved in patient diagnosis, appliance design, and treatment planning and monitoring.
- U.S. Pat. No. 6,632,089 to Rubbert discloses an interactive, software-based treatment planning method to correct a malocclusion.
- the method can be performed on an orthodontic workstation in a clinic or at a remote location such as a lab or precision appliance manufacturing center.
- the workstation stores a virtual three-dimensional model of the dentition of a patient and patient records.
- the virtual model is manipulated by the user to define a target situation for the patient, including a target archform and individual tooth positions in the archform.
- Parameters for an orthodontic appliance such as the location of orthodontic brackets and resulting shape of a customized orthodontic archwire, are obtained from the simulation of tooth movement to the target situation and the placement position of virtual brackets.
- the effective use of a customized archwire is limited to a single stage of orthodontic treatment namely finishing.
- bracket wire systems and aligners are largely unknown and indeterminate and can only be controlled to a very limited extent. This commonly results in unpredictable and unintended for large tooth movements such as space closure, expansion, constriction, root correction, distalization, intrusion, extrusion or jaw position correction. Furthermore, many of these devices cannot be used concurrently to control various tooth movements or jaw positioning simultaneously in a predictable way. Additionally, these devices do not easily lend themselves to adjustment in appliance features to generate predictable forces to provide controlled and predictable orthodontic correction.
- an orthodontic appliance in one aspect, includes an elongated receptacle and an elongated member telescopically extending from the receptacle and adapted to couple to one or more teeth.
- the orthodontic appliance includes an elastic coupled to the elongated member and configured to move the elongated member towards the elongated receptacle. Further, a movement of the elongated member relative to the elongated receptacle facilitates—repositioning of one or more teeth.
- an orthodontic appliance comprising a first telescopic assembly including a first elongated receptacle coupled to one or more first teeth and a first elongated member telescopically extending from the first elongated receptacle and adapted to couple one or more second teeth.
- the first telescopic assembly further including a first elastic member attached to the first elongated member and the first elongated receptacle, and is adapted to move the first elongated member toward the first elongated receptacle.
- the orthodontic appliance includes a second telescopic assembly having a second elongated receptacle coupled to one or more third teeth and a second elongated member telescopically extending from the second elongated receptacle and adapted to couple one or more fourth teeth.
- the second telescopic assembly further including a second elastic member attached to the second elongated member and the second elongated receptacle, and is adapted to move the second elongated member toward the second elongated receptacle.
- an orthodontic appliance in yet another aspect, includes a telescopic assembly having an elongated receptacle and an elongated member telescopically extending from the receptacle, and adapted to couple to one or more teeth.
- the telescopic assembly further including an elastic member coupled to the elongated member and configured to urge the elongated member towards the elongated receptacle.
- a movement of the elongated member relative to elongated receptacle facilitates a first movement of one or more teeth.
- the orthodontic appliance also has an attachment member coupled to the telescopic assembly and is configured to facilitate a second movement of the one or more teeth.

Abstract
Description
- This application is a non-provisional application corresponding to the pending provisional application No. 62/722,319, filed Aug. 24, 2018. This application is also related to applications titled “Patient-Centered System and Methods for Total Orthodontic Care Management and “Modular Aligner Devices and Method for Orthodontic Treatment incorporated by reference herein.
- The present invention generally relates to orthodontic appliances, more particularly to a system of orthodontic appliances for the comprehensive treatment of malocclusions, which allows for the application of substantially statically determinate forces and moments to generate controlled and predictable orthodontic correction of a malocclusion.
- Malocclusion of the dentition and jaws are commonly seen in the general population. While the degree or severity may vary from person to person, it is estimated that roughly two out of every three individuals suffer from malocclusions of some type. Malocclusions are generally corrected to improve aesthetics, restore normal oral function, establish improved relationships of the teeth in their bony housing and gum tissue. These measures generally result in better oral health. Malocclusions manifest themselves in three reference planes of space namely the transverse, the vertical and the sagittal plane of space. Some common malocclusions include crowded or misaligned teeth, cross bite, deep bite, open bite, overjet, under bite, etc. Over the years a number of strategies have evolved to treat the malocclusions. For instance, crowding is commonly managed by creating space in the dental arches. This may be achieved by extraction of selected teeth or by non-extraction approaches which may involve shaving of teeth, to reduce their size, in order to fit them in the dental arches or expansion of the teeth or advancing the teeth forward or pushing the back teeth further back to create space to correct the crowding.
- Commonly known treatment methodologies include use of brackets and arch wires and aligners. Arch wires are engaged into bracket slots with the brackets bonded to the teeth, and since they distort elastically, as the arch wires recover to their original shape, they create forces that trigger a biological response to move the teeth. These brackets may be placed on the front of the teeth i.e. labial surfaces located on exposed visible surfaces of teeth or lingual surfaces that are located on the back or inner surfaces of teeth. The location of brackets on the teeth and bends in the arch wire determine the magnitude and direction of forces applied on the teeth. Furthermore, elastically deformable elements such as coil springs, elastomeric chains may also be deployed at key locations to provide additional forces to move teeth Aligners are removable plastic shells that cover the entire surface of teeth and their action is commonly coupled with attachments bonded on teeth. The shells are distorted elastically when they engage the teeth and as they recover their programmed shape they create forces to move teeth.
- U.S. Pat. No. 5,431,562 to Andreiko et al. describes a computerized, appliance-driven approach to orthodontics. In this method, first certain shape information of teeth is acquired. A uniplanar target arch form is calculated from the shape information. The shape of customized bracket slots, the bracket base, and the shape of an orthodontic arch-wire, are calculated in accordance with a mathematically-derived target archform. The goal of the Andreiko et al. method is to give more predictability, standardization, and certainty to orthodontics by replacing the human element in orthodontic appliance design with a deterministic, mathematical computation of a target archform and appliance design. Hence the '562 patent teaches away from an interactive, computer-based system in which the orthodontist remains fully involved in patient diagnosis, appliance design, and treatment planning and monitoring.
- More recently, in the late 1990's Align Technologies began offering transparent, removable aligning devices as a new treatment modality in orthodontics. In this system, a plaster model of the dentition of the patent is obtained by the orthodontist and shipped to a remote appliance manufacturing center, where it is scanned with a laser. A computer model of the dentition in a target situation is generated at the appliance manufacturing center and made available for viewing to the orthodontist over the Internet. The orthodontist indicates changes they wish to make to individual tooth positions. Later, another virtual model is provided over the Internet and the orthodontist reviews the revised model, and indicates any further changes. After several such iterations, the target situation is agreed upon. A series of removable aligning devices or shells are manufactured and delivered to the orthodontist. The shells, in theory, will move the patient's teeth to the desired or target position.
- U.S. Pat. No. 6,632,089 to Rubbert discloses an interactive, software-based treatment planning method to correct a malocclusion. The method can be performed on an orthodontic workstation in a clinic or at a remote location such as a lab or precision appliance manufacturing center. The workstation stores a virtual three-dimensional model of the dentition of a patient and patient records. The virtual model is manipulated by the user to define a target situation for the patient, including a target archform and individual tooth positions in the archform. Parameters for an orthodontic appliance, such as the location of orthodontic brackets and resulting shape of a customized orthodontic archwire, are obtained from the simulation of tooth movement to the target situation and the placement position of virtual brackets. However, the effective use of a customized archwire is limited to a single stage of orthodontic treatment namely finishing.
- Additional limitations with the both the bracket wire systems and aligners are that the force system created are largely unknown and indeterminate and can only be controlled to a very limited extent. This commonly results in unpredictable and unintended for large tooth movements such as space closure, expansion, constriction, root correction, distalization, intrusion, extrusion or jaw position correction. Furthermore, many of these devices cannot be used concurrently to control various tooth movements or jaw positioning simultaneously in a predictable way. Additionally, these devices do not easily lend themselves to adjustment in appliance features to generate predictable forces to provide controlled and predictable orthodontic correction.
- In light of the discussion above, there is required an orthodontic appliance system that does not suffer from above mentioned deficiencies.

- It is an objective of the present invention to develop an orthodontic appliance system that include a basic framework with extensions that can be used for space closure, intrusion, root correction, distal movement, expansion, constriction extrusion, alignment, retention and stabilization and jaw position correction. These movements can be performed concurrently or in tandem or staged and sequenced in a manner to provide the most safe, reliable, efficient, and effective care for a patient. In several embodiments, the basic framework is envisaged to include longitudinal, arch shaped and transverse components that may be attached to teeth or the bone of a patient using relatively fixed semi fixed or removable means. The components may include solid and/or tubular bent portions and be combined with each other using several attachment mechanisms. In such scenarios, the framework with its associated members will act as a passive (non-force applying) structure and will be adapted to receive other active elements/member that are capable of force applications. These active elements may include structure that are capable of at least partial elastic or elastomeric deformation. Also, it is envisaged that an orthodontic appliance designed for one region of the teeth (such as buccal, lingual or occlusal) may be implementable to another region with very basic modifications without departing from the scope of the invention. Referring to figures now, the invention will be explained in more detail.
