Separators: a review of uses and limitations

Abstract

Orthodontic separators (commonly known as spacers) are elastomeric or metal auxiliary appliances, which are often used in Orthodontics to create space between teeth and allow fitting of an orthodontic band. Separators can also be used to create space for other reasons such as to facilitate interdental reduction. This paper describes common uses and a variety of other purposes that can be achieved with the separator including: management of ectopic teeth; the creation of attachments on teeth; uprighting molars and detection of cavitated carious lesions. Separators have many benefits, however, they can cause discomfort and also periodontal problems if they remain dislodged beneath the contact point. CPD/Clinical Relevance: Orthodontic separators can be used for a variety of clinical situations by both Orthodontists and General Dental Practitioners alike as a useful adjunct in the dental armamentarium.

The Effectiveness of Low-Level Laser Therapy in Pain Induced by Orthodontic Separator Placement: A Systematic Review

“…1,4 Thus, good pain management plays a key role in patient satisfaction with treatment and leads to better cooperation with the doctor. [5][6][7] The aim of using separators which are most commonly placed between the second premolars, first and second molars is to make the placement of orthodontic bands simpler. 8 The placement of separators is tightly associated with pain and discomfort.…”

“…3 Several methods are used to manage discomfort: Among several methods currently available, oral analgesics, especially the non-steroidal anti-inflammatory drugs (NSAIDs) and bite wafers, are frequently prescribed by orthodontists. [4][5][6] There are still some concerns regarding the delaying effect of employing NSAIDs on tooth movement orally or topically. 7,8 Low-level laser therapy (LLLT) has been widely adopted for the management of acute and chronic pain in various conditions.…”
