A plain band is a pre-formed SS orthodontic band with no attachments pre-welded. The clinician selects the band size by try-in, and the band is sent to the lab with the model for the lab to weld the required attachments (tubes, lingual hooks, expander arms, Herbst pivots, etc.) in the correct positions. This allows maximum customization compared to pre-welded bands. Plain bands are the standard component used in CFL-fabricated appliances requiring custom molar band work.
Plain bands (smooth, unattached molar bands) provide the circumferential steel ring that is cemented to a molar when a welded attachment (tube, hook, or clevis) will be added to the band at chairside after cementation, or when the band serves as an anchor base for a lab-fabricated appliance (RPE, lingual arch, TPA). In lab-fabricated fixed appliances, bands are the connection between the intraoral tooth surface and the soldered appliance framework.
Plain bands are used when a standard pre-welded molar tube is insufficient — most commonly as the anchor component for lab-fabricated appliances: RPE bands, lingual arch bands, TPA bands, Herbst tube bands, and headgear combination bands. They are also used in banding first molars when bonded molar tubes are contraindicated (inadequate enamel, heavy bruxism, high debonding risk).
Band fitting is a chairside procedure: a series of try-in bands in increasing sizes are seated until the correct size is found — the band should seat fully to the gingival margin, contact the tooth on all four surfaces, and resist dislodgement with moderate occlusal force. Sizing is critical; an oversized band rocks and will debond; an undersized band cannot seat. After sizing, the band is sent to the lab for attachment welding, then returned for cementation with glass ionomer or resin-modified glass ionomer cement.
Poor band fit is the leading cause of molar band cementation failure. Short clinical crowns reduce the cementation surface area. Patients with nickel sensitivity (nickel is the primary component of stainless steel bands) may require alternative materials. Banded molars accumulate more plaque at the gingival margin than bonded alternatives.
Lab welds required attachments to plain bands during appliance fabrication. Related: Band with attachments band with attachments (pre-welded).
