Kids-e-Dental Bands comes in universal band design with attached tube for connecting space maintainer wires to prevent pre mature loss of space. Space Maintainer Wires which can be used along with these Bands : Straight Loops Curved Loops Distal Shoe Band and Loop Space Maintainers - Before the new molar erupts, band and loop spacers make it a point to leave ample space for it. This is done to preserve the teeth’s proper alignment, while making sure the new teeth will erupt in its proper position. A stainless steel band is placed temporarily around a permanent molar, with a stainless steel wire that loops out to extend to the second primary molar, leaving a space between them for the second premolar eruption. The band and loop space maintainer are only helpful in maintaining a single missing tooth space. It may not be recommended for two or more succeeding missing teeth as it will be needing anchorage. Distal Shoe Space Maintainers - Used to maintain the space of a primary second molar that has been lost before the eruption of the permanent first molar. An unerupted permanent first molar drifts mesially within the alveolar bone if the primary second molar is lost prematurely. The result of the mesial drifts results in loss of arch length & possible impaction of the second premolar. The distal shoe is usually retained with a band instead of a stainless steel crown so that it can be replaced by another type of space maintainer after the permanent first molar erupts. To be effective, the guide plane must extend into the alveolar process so that it contacts the permanent first molar approximately 1 mm below the mesial marginal ridge, at or before its emergence from the bone. Advantages : Single appointment No impression and model pouring Precise and no laboratory errors involved Universal bands decreases inventory Cost effective Very useful in sedation cases.
