An orthodontic finishing positioner for maloccluded teeth to which are

secured coupling members having portions protruding from the sides of the

teeth includes a body constructed of an elastomer base material adapted to

be operatively positioned about the teeth and coupling member of at least

one dental arch of a patient. The positioner body is arcuate in shape and

defines a recess for receiving teeth of at least one dental arch wherein

the recess includes walls defining teeth-engaging surfaces shaped

generally complementary to the surfaces of the teeth of the one dental

arch when the teeth therein are positioned in a predetermined or ideal

orientation. The recess walls further defines a series of indentations

disposed across the teeth-engaging surfaces wherein each indentation being

shaped to nestingly accept a corresponding coupling member so that when

the positioner body is operatively positioned within the patient's mouth

and stretched about the teeth of the one dental arch so that the teeth

thereof are operatively received by the recess of the arcuate-shaped

portion and each coupling member is accepted by a corresponding

indentation, the stretched body effectively grasps the teeth and acts

against the teeth and the coupling member to bias the teeth of the one

arch toward the predetermined orientation. The method of the invention

includes the steps involved in constructing the positioner of the

invention. Such construction steps include the constructing of an

impression-formed model of the teeth and coupling members of the one

dental arch, repositioning the teeth-simulating portions of the model to a

predetermined orientation and utilizing the model, with its repositioned

teeth-simulating portions, as a standard for the formation of the desired

positioner.

You can fix a gap by using a composite resin (tooth colored filling material)on the front surfaces of your teeth. You may also choose to have veneers placed on the teeth. Or the most drastic and expensive aproach is to have dental implants. You need to discuss all orthodontic options with your orthodontist before choosing these cosmetic options. He or she can only tell you if there are no other orthodontic treatments for you.


4 year old has decay in upper front tooth should tooth be removed or root canal?

If the tooth can be saved with a root canal (pulpotomy) or other treatment, it should be done. The adult tooth that will replace this baby tooth may not erupt until the child is six or seven years old, and the dental arch may shrink if the baby tooth is lost too soon. This will lead to problems when the adult tooth erupts and the child may require extensive and expensive orthodontic treatment to correct the problems.
