Further studies in retention of the orthodontic band.
A statistical analysis of 1,976 conventional orthodontic bands cemented to the teeth of 102 patients was carried out to try to establish the relationship of sex of the patient, age of the patient, and the type of malocclusion to the retention of the orthodontic band. The effect of treatment time and the presence or absence of extraoral traction on band recementation were also considered. The results obtained from the study led to the following conclusions: 1) There is no significant difference in the degree of band recementation occurring during orthodontic treatment between girls and boys. 2) There appears to be a tendency for bands to be recemented less frequently in patients 17 years of age and over. A larger sample would be necessary before being more definite. 3) The Class II, Division 2 type of incisor relationship may predispose to a higher rate of band recementation. Once again a greater sample size would be essential to be more categorical. 4) The percentage of bands recemented increased as the duration of treatment increased. 5) The use of early Kloehn cervical facebow therapy leads to a higher rate of band recementation on the maxillary molars.
