| 摘要 | An adjustable orthodontic band conforms around teeth of varied sizes. The band may be elastic or a superelastic alloy, and elastically expands under force to fit different teeth. Or the band has shape memory, e.g. shape memory metal alloy, with variable circumference under applied energy such as heat. The band may be solid heat shrink or elastomeric polymer, or metal alloy. Or, interconnected struts are separated by voids that may receive cement or are covered with elastomer . Adjustability may vary along the band. A kit of adjustable bands has varied adjustable size ranges, and may include no more than about 8 or fewer bands together covering an overall range of up to 30 % or more difference in circumference. One band having at least a 30 % range of adjustable circumference also may be provided for each tooth type. The adjustable bands are pre-coated with cement, and are pre-packaged in a UV and moisture protective container. Estimated size is all that is required to choose the correct band for most teeth. | ||||||
