Abstract
Placement of bands on the posterior teeth are preferred to bonding due to heavy masticatory forces. Placement of bands needs interdental separation of 0.2 mm, which requires prior placement of separators for couple of days. Various types of separators are commercially available in the market, with their own advantages and disadvantages. A scientific review of this most useful armamentarium in orthodontics was lacking and therefore a search was undertaken to gather information on separators. This article deals with various aspects of separators in detail.Orthodontic Journal of Nepal, Vol. 6 No. 1, June 2016, pp.37-40
Highlights
Placement of bands in posterior region is preferred over bonding, as posterior teeth experience larger masticatory force than the anteriors
The average periodontal ligament (PDL) space is 0.25 mm and placement of a 0.16 mm thick metal band without proper tooth separation can lead to contraction of the alveolar bone which in turn shall produce hyalinization areas in the PDL1 and evoke pain.[2,3]
Separation is an orthodontic procedure aiming at slightly loosening the tight interproximal contacts between teeth to create space for the fitting of orthodontic brands by forcing or wedging the teeth apart usually for one week.[5]
Summary
Placement of bands in posterior region is preferred over bonding, as posterior teeth experience larger masticatory force than the anteriors. The average periodontal ligament (PDL) space is 0.25 mm and placement of a 0.16 mm thick metal band without proper tooth separation can lead to contraction of the alveolar bone which in turn shall produce hyalinization areas in the PDL1 and evoke pain.[2,3]. Separation of teeth to create interproximal space is the first step in banding.[4] It is important to remember that, as separator placement is the done in the first appointment a painless procedure proves to be an important step in building trust with the patient. Orthodontic separators though used daily in orthodontic practice is the least researched auxiliary till date
