3M AlastiK B Modules for Tooth Retraction

3M AlastiK B Modules are elastic orthodontic modules supplied as two attached units per piece, designed to be used by orthodontists to help retract adjacent teeth or assist with correcting tooth rotations during active treatment. The paired module format allows the clinician to engage both attached elastics onto the archwire or bracket hooks in a single placement, applying force across adjacent teeth as part of the planned tooth movement for that stage of treatment.

Elastic modules like these are a routine consumable used throughout many phases of fixed appliance treatment, replaced regularly as they lose elasticity or as the treatment plan calls for adjusted force application at different points during the course of care. Because module force and stretch characteristics vary between products, orthodontic practices typically standardise on specific module types like AlastiK B for particular clinical situations, such as retraction or rotation correction, while using other module or elastic chain products for different tooth movement needs elsewhere in the arch.

Practices running an active orthodontic caseload keep a stock of these modules on hand as part of their routine adjustment supplies.
