Definitions
- the assembly of the invention includes a spring which is configured into a combined helical and Archimedes spiral, and which is used in conjunction with a slotted bracket mounted on the tooth, and the usual arch wire, with the arch wire being held in the slot of the bracket by one of the actuating arms of the spring.
- the spring assembly of the present invention carries out Beggs Orthodontic Technique principles of free tipping and pure uprighting to the canines and first or second premolars, as mentioned above.
- the uprighting springs which are presently on the market do not provide true uprighting movements.
- Such prior art springs rotate the crown of the tooth, and they cause transverse motion while they are uprighting and bringing the roots of the canines and second premolars together. This transverse motion creates a space opening between the canine and the second premolar marginal ridges which have already been closed in the second stage of the Begg Technique.
- the uprighting assembly of the present invention is predicated upon advanced engineering principles to as to allow the teeth to upright in a true uprighting motion.
- the stress of the spring rotation in the spring assembly to be described is placed in such a manner that the pivot about which the tooth turns is in the longitudinal axis of the tooth which does, as Begg intended, move the roots of the teeth together, leaving the crowns touching at the end of the second stage of the Begg Technique where so much time has been consumed in the prior art practices in closing this space.
- the actuating arm of a dual type of spring assembly engages the arch wire in a manner such that it does not overlap, touch or slide into the arm of the spring on the opposing tooth. There is free movement of the tooth in a pure uprighting direction, and there is no interference with the adjacent teeth.
- the spring assembly of the present invention is more hygienic than the prior art devices, in that there is less food entrapment around the uprighting spring assembly of the invention. This is because the arms of the uprighting springs ofthe invention do not come together in the open space between the second premolars and the canines, as in the case with the prior art arrangements.
- the uprighting springs now in use must be ligated, or otherwise attached to the arc wire, and they also have a tendency to push the arch wire out of the associated tooth bracket.
- the uprighting spring assembly of the present invention holds the arch wire into the slot of the accompanying bracket so that ligating is unnecessary, and this feature results in time saving to the orthodontist.
- a further advantage of the spring assembly of the present invention is that it is universal and may be used on either side of the arch, to the right or left, and in both the upper and lower arch. Moreover, no marking or measuring is required for fitting the assembly. All that is needed is one simple bend of an arm at one end of the spring for securing the spring into the bracket, and hooking the other end of the spring over the arch wire when a single unit is used, or bending the arm at the end of the second spring into its tooth bracket, when a dual unit is used.
- the combination of the helical and Archimedes spiral in the configuration of the spring assembly of the invention provides a more continuous action than any uprighting spring presently in existence, and in a pure and true uprighting motion.
- the uprighting spring of the present invention may be used on any tooth in the mouth of the patient. Further in vivo studies have shown that patients suffer less discomfort with the spring of the invention as compared with the usual prior art uprighting springs.
- the construction of the spring assembly of the invention also provides an indication for proper installation. That is, if the activating arm is engaging with the arch wire mesial of the tooth, the uprighting motion will bring the crown of the tooth to the mesial. This also applies to the distal engagement.
- the uprighting spring assembly of the invention may be a single or dual type, as mentioned above.
- the dual type provides for the uprighting of two adjacent teeth simultaneously and provides an additional force for bringing these teeth into the open space between them. This is particularly useful in the Beggs Orthodontic Technique since in the majority of cases, the first premolars are removed leaving a space between the canine and the second premolar which must be closed. This action also permits the teeth to tip into the open space so uprighting is nearly always a requirement in such cases. Therefore, the dual uprighting spring assembly of the invention performs the function of two uprighting springs of the single type, an in addition to paralleling the roots of the teeth, serves to bring the teeth together.
- FIG. 1A is a representation of a tooth uprighting spring assembly constructed in accordance with the the concepts of the invention and in an actuated condition;
- FIG. 1B is a view like FIG. 1A, and showing the state of the tooth and spring assembly at the completion of the uprighting operation;
- FIG. 2A is a representation of a dual type spring assembly incorporating the concepts of the invention and operating on two adjacent teeth, the assembly being shown in its actuated condition in FIG. 2A;
- FIG. 2B is a view like FIG. 2A and showing the condition of the teeth and of the dual type spring assembly of FIG. 2A at the completion of the tooth straightening process.
- FIGS. 1A and 1B The single type of uprighting spring shown in FIGS. 1A and 1B is designated 10, and it has a first end 10a which extends into a slot in a bracket 12 which, in turn, is mounted on a band 14 extending around the tooth to be straightened.
- a usual arch wire 16 passes through the slot in the bracket 12, and is held in the slot by the end 10a of the spring 10.
- the spring has a helical spiral portion 10!; adjacent the end 10a, and it has an Archimedes spiral portion 10c adjacent the other end 10d of the spring, which other end is looped around the arch wire 16, so as to provide the desired straightening and tipping action to the tooth.
- the force exerted by the spring 10 on the tooth provides the desired uprighting movement.
- the particular configuration of the uprighting spring of FIGS. 1A and 1B is such that the stress of spring rotation placed on the tooth is such that the pivot is in the longitudinal axis of the tooth so that the intendment of the aforesaid Beggs Orthodontic Technique is carried out.
- the dual uprighting spring of FIGS. 2A and 2B is similar to the single spring described above, except that the uprighting of two adjacent teeth is provided simultaneously, and the additional force to bring the teeth together is also provided.
- the dual uprighting spring is designated generally as 100, the spring has a first end 100a which extends into the slot in the bracket 12 of the left-hand tooth, as in the previous embodiment, and it has a second end 10% which extends into the slot in the second tooth.
- a helical spiral 1000 is provided adjacent the first end and a similar helical spiral 100d is provided adjacent the second end.
- the intermediate portion of the dual spring is looped into a spiral helix l00e.
- the result of the uprighting not only uprights the teeth with a true uprighting motion, but the stress is such as to move the roots of the teeth together, leaving the crowns touching at the end of the stage, as intended in the Begg Orthodontic Technique.
- the invention provides, therefore, an improved orthodontic appliance in the form of an uprighting spring which provides true uprighting movements, and which serves to carry out faithfully the intendments of the Beggs Orthodontic Technique.
- the orthodontic appliance of the invention may be a single or dual type, and it is apparent that other modifications may be made.
- the following claims are intended to cover all the modifications which fall within the scope of the invention.
- An orthodontic appliance in the form of a spring for tipping and uprighting teeth, and for use in conjunction with an arch wire and a bracket mounted on the tooth to be processed and which receives the arch wire in a slot therein, said appliance comprising:
- a spring having a first end extending into said slot in said bracket, and said spring further having a helical spiral portion adjacent said first end, and in which said spring has a second end looped around the end of said bracket to form an Archimedes spiral between said helical spiral portion and said second end, and in which said second end is configured to engage the arch wire to provide the desired spring tension by the spring, so as to impart a stress to the tooth so as to pivot the tooth about a point in the longitudinal axis of the tooth.
- An orthodontic appliance in the form of a spring for tipping and uprighting teeth, and for use in conjunction with an arch wire and a bracket mounted on the tooth to be processed and which receives the arch wire in a slot therein, said appliance comprising:
- a spring having a first end for extending into said slot in said bracket, and said spring further having a helical spiral portion adjacent said first end, in which said spring has a second end for extending into the slot in a bracket in an adjacent tooth, and 'said spring further has a helical spiral portion adjacent said second end, and in which said spring has a looped portion intermediate the aforesaid helical spring portions and two relatively straight portions respectively extending between the intermediate looped portion and the aforesaid helical spiral portions.
