Definitions
- the present invention is related to an improved method to correct orthodontic malocclusions. It includes a first phase employing traditional molar orthodontic appliances such as bands, wires and the like. A second phase employs a plastic tray which exerts orthodontic correcting forces to treat the malocclusion.
- Orthodontics relates to creating space and moving the teeth within that space traditionally with appliances, wires, and some form of ligation.
- the lay word used is braces. This is a highly labor intensive system requiring frequent reactivations by the orthodontist to adjust the wires.
- These braces are mounted to the teeth using an adhesive/acid system that is uncomfortable for some adult patients and time consuming for the practitioner. It is also expensive.
- Align Technology introduced treating patients, mainly adults, with a computer designed series of plastic trays. These trays take the original impression of the patient's teeth and use a digital database to create an actual mold of the teeth and then advance that mold's information to create a series of trays that attempt to treat the patient's malocclusion without braces. This has proven very expensive and time consuming, as it requires the long lead times to start treatment and it takes the plastic trays a long period of time to affect tooth movement. Busy adults have to be patient and carefully follow the regimen and the orthodontist/manufacturer many times has to recreate the series of trays as they need a mid-course correction due to either non- compliance or errors in the computer assumptions. Align, the original inventor of digital aligners, actually patented mid-course corrections and insurance when treatment is started. While the patient has virtually invisible treatment, it may take years to complete and generally involves a big compromise when compared to traditional treatment.
- an appliance such as the Pendex as shown in Figure 1 can be used to expand the maxillary arch width while maintaining the anteriors with a clear passive tray.
- the expansion as shown above allows great space to be gained so that less enamel reduction and easier repositioning of the anterior teeth to the prescribed ideal finish may be more easily and predictably maintained.
- the quad helix has been proven for decades to be useful to expand unnaturally narrow arches, especially younger females. After phase one with the quad helix, the digital model and the case will have most obstructions removed for path analysis and the quad helix is virtually impossible to see.
- Palatal arch bars and their sheathes are very simple devices to rotation and distallize molars creating large amounts of space to allow the pre-molars to freely drift posteriorly while holding the anteriors in a passive clear tray during Phase I.
- Lingual arches used on the mandibular behind the teeth, are connected to the molar band and used to upright the anterior teeth while placing gentle pressure to promote dental alveolar lateral growth.
- no lower plastic tray is used until Phase II and again there will be greater space to use while making the digital prescriptive trays for Phase II.
- a two-phase method of orthodontically correcting maloccluded teeth that includes: A first phase aesthetic treatment regimen that begins with traditional molar orthodontic appliances and therapy to rotate, align, intrude and/or level the molar area. Path analysis via a CAD/CAM to see if stripping is needed and where it is best applied based on tooth width and arch width. A clear retaining tray is made to control the balance of teeth during Phase One.
- This invention concerns an improved method of aesthetically treating more patients using a two-phase treatment plan. It starts with an impression or digital scan of the patient's teeth and bite registration being sent digitally to a 3-D modeler such as OrthoCAD where a digital model of the teeth and their relationship are established. Millimeters of crowding are determined and the type of malocclusion analyzed to chart the following process.
- Bands or acrylic plates as indicated are applied to the posterior molars and mechanics used to derotate, intrude, torque, expand, and/or upright the molars, creating the space for at least one tooth's worth of space in each arch. This will allow better treatment with the plastic activators on the anteriors without fixed appliance therapy and anchorage for better retention after treatment.
- Figure 1 is a perspective view of one embodiment of a traditional molar orthodontic appliance useful in the practice of the present invention.
- Figure 2 is a perspective view of another embodiment of a traditional molar orthodontic appliance useful in the practice of the present invention.
- Figure 3 is a perspective view of another embodiment of a traditional molar orthodontic appliance useful in the practice of the present invention.
- Figure 4 is a perspective view of another embodiment of a traditional molar orthodontic appliance useful in the practice of the present invention.
- Figure 5 is a perspective view of a tray useful as a retainer or as one of a series of aligner trays used in the practice of the present invention. Detailed Description of the Invention
- Phase I Phase I will last 2-6 months. Records will be kept of the individual tooth and arch width measurements before the stripping and after. Again, digital 3-D simulation can perform path analysis and the ideal amount of space needed and where it can be gained. Between stripping of anteriors and rotation of molars, it's possible that extraction of teeth on marginal cases can be avoided.
- a final tray such as tray (10) in Figure 5 is formed for all the teeth after the bands have been removed and placed to finalize correction and begin retention. [0022] Generally, this process is to address the millions of adults that are at or near Class I or Class II Division I molar relationships and have crowded anteriors. Also, many patients that already completed orthodontic treatment in their youth and simply need to correct unattractive rotations could benefit from this system.
