Band selection and positioning
Bands are fitted routinely to the first molars. Usually the week before band placement,separators are placed in order to move the adjacent teeth slightly apart.
This slight spacing makes it easier for the operator, and reduces the discomfort to the patient, when fitting bands. Band selection is usually made on a trial-and-error basis. You can get an indication of the correct size by comparing bands of different sizes with the patient's study models.
Bands are placed over the tooth so that they are a tight fit, band pushers are carefully used to press the band into place. Care is required as it is easy to slip and damage the soft tissues.
The bands used in Newcastle are oriented with the hook to the gingivae and orientated distally - see below
The mesial edge of the molar tube should be in-line with the tip of mesial buccal cusp of the molar. The tube should be parallel to the molars occlusal surface.
- Ensure that the band is level with the occlusal plane. The figure on the left (below) show the common fault of the mesial of the band being seated too low.
- The mesial edge of the molar tube should be in line with the mesial-buccal cusp of the molat when viewed from the occlusal surface. (illustration on right).
