The bracket bases are positioned on a lingual surface and/or a facial surface of the teeth. Each bracket base includes a first surface, a second surface, and at least one first interlocking element. The first surface is rigidly attached to the lingual surface and/or the facial surface of the teeth. The second surface opposes the lingual surface and/or the facial surface of the teeth. The first interlocking element is attached to and positioned in a direction substantially perpendicular to or parallel to the second surface of each bracket base. The brackets include at least second interlocking element that interlocks with the first interlocking element. The arch wire is inserted through a slot channel of each bracket. The bracket and the arch wire are infused and rigidly anchored within enclosing layers. ## Claims ### Claim 1 An orthodontic bracket and wire system detachably attachable to teeth for guiding alignment of teeth of one of an upper jaw and a lower jaw of a patient, said orthodontic bracket and wire system comprising: a plurality of bracket bases configured to be positioned on one or more of a lingual surface and a facial surface of said teeth, each of said bracket bases comprising: a first surface configured to attach rigidly to each of said one or more of said lingual surface and said facial surface of said teeth; a second surface configured to oppose said each of said one or more of said lingual surface and said facial surface of said teeth; and at least one first interlocking element configured to detachably attach to said second surface of said each of said bracket bases and positioned in one of a direction substantially perpendicular to and a direction substantially parallel to said second surface of said each of said bracket bases; a plurality of brackets, each of said brackets comprising at least one second interlocking element configured to interlock with said at least one first interlocking element of said each of said bracket bases in said one of said direction substantially perpendicular to and said direction substantially parallel to said second surface of said each of said bracket bases, said each of said brackets further comprising a slot channel passing through said each of said brackets; at least one arch wire configured to be inserted through said slot channel of said each of said brackets on said one or more of said lingual surface and said facial surface of said teeth and extending from a molar region on a first side to a molar region on a second side of a dental arch; said at least one arch wire and said brackets coated with a hard plastic material and infused within one or more of an inner lingual side and an inner facial side of enclosing layers for rigidly anchoring said at least one arch wire and said brackets within said inner lingual side and said inner facial side of said enclosing layers, wherein said enclosing layers comprise: a soft enclosing layer extending from said lingual surface to said facial surface of said teeth, wherein said soft enclosing layer is elastic; and a hard enclosing layer enclosing said soft enclosing layer and extending from said lingual surface to said facial surface of said teeth, wherein said hard enclosing layer is rigid. ### Claim 2 (depends on 1) The orthodontic bracket and wire system of claim 1, wherein said slot channel is configured with a predefined cross section to accommodate said arch wire configured with said predefined cross section, wherein said predefined cross section is one of a rectangular cross section and a circular cross section. ### Claim 3 (depends on 1) The orthodontic bracket and wire system of claim 1, further comprising a primary frame wire traversing from said facial surface to said lingual surface of said teeth through cusps of said teeth, wherein said primary frame wire is configured to secure and anchor to said teeth said brackets that are interlocked to said bracket bases. ### Claim 4 (depends on 3) The orthodontic bracket and wire system of claim 3, wherein said primary frame wire is made of one of a metal wire and a fiberglass wire. ### Claim 5 (depends on 4) The orthodontic bracket and wire system of claim 4, wherein said primary frame wire is coated with a color that matches one of said teeth and gums. ### Claim 6 (depends on 4) The orthodontic bracket and wire system of claim 4, further comprising one or more tubes fixedly attached to said primary frame wire for engaging with an extraoral orthodontic appliance. ### Claim 7 (depends on 3) The orthodontic bracket system of claim 3, further comprising one or more secondary frame wires traversing from said facial surface to said lingual surface of said teeth through cusps of said teeth, wherein said one or more secondary frame wires rigidly positioned individually around each of said teeth to allow said each of said teeth to move independent of each other, and wherein said one or more secondary frame wires are anchored to one of said at least one arch wire and the primary frame wire. ### Claim 8 (depends on 7) The orthodontic bracket and wire system of claim 7, wherein said one or more secondary frame wires are configured in one or more of a loop configuration, a spiral configuration, a cross bar mesh configuration and an orthogonal mesh configuration. ### Claim 9 (depends on 1) The orthodontic bracket and wire system of claim 1, wherein said bracket bases are made of one of a rigid metal, an acrylic material, a composite material, and a ceramic material. ### Claim 10 (depends on 1) The orthodontic bracket and wire system of claim 1, wherein said at least one arch wire and said brackets are coated with a polymeric material for rigidly bonding each of said at least one arch wire and said brackets to said enclosing layers using one or more of a plurality of infusion methods, wherein said infusion methods comprise electric heating and microwave heating. ### Claim 11 (depends on 1) The orthodontic bracket and wire system of claim 1, wherein said at least one first interlocking element of said each of said bracket bases comprises one of a ball projection and a socket, and wherein said at least one second interlocking element of said each of said brackets comprises a corresponding one of said socket and said ball projection to allow interlocking of said at least one first interlocking element to said at least one second interlocking element. ### Claim 12 (depends on 1) The orthodontic bracket and wire system of claim 1, further comprising a cross bar positioned below each of said at least one first interlocking elements of said each of said bracket bases, wherein said each of said brackets further comprises a receptacle to engage said cross bar and restrict movement of said each of said brackets over said each of said bracket bases. ### Claim 13 (depends on 1) The orthodontic bracket and wire system of claim 1, wherein said at least one arch wire is configured with one of a plurality of arch forms. ### Claim 14 (depends on 1) The orthodontic bracket and wire system of claim 1, wherein said at least one arch wire positioned on said lingual surface of said teeth is configured with a twisted arch form at a canine area of said teeth and with a uniform arch form in regions other than said canine area. ### Claim 15 (depends on 1) The orthodontic bracket and wire system of claim 1, further comprising one or more hooks configured to be positioned on one of one or more canines and one or more molars of one of said upper jaw and said lower jaw. ### Claim 16 (depends on 15) The orthodontic bracket and wire system of claim 15, further comprising one or more elastics positioned on said one or more hooks, wherein said one or more elastics are configured to engage between said teeth in said upper jaw and said lower jaw. ### Claim 17 (depends on 1) The orthodontic bracket and wire system of claim 1, further comprising a mesh element conforming to a shape of said teeth and positioned on said each of said bracket bases around said at least one first interlocking element, wherein said mesh element is configured to secure said each of said bracket bases to said enclosing layers.
