Assessment of posterior crossbite correction requires that treatment effect is separated from normal growth. Both short and long term outcomes relative to early crossbite correction will be discussed. Changes in the transverse, perimeter, vertical and antero-posterior planes of space will be reviewed. Comparisons between rapid and slow maxillary expansion will be made as it relates to treatment response and outcome. Since clinicians use a variety of expansion appliances, research on success rates and outcomes will be presented by appliance type. This presentation will provide data that the clinician can apply directly to patient care, knowing that they will apply the best available evidence for the treatment of posterior crossbite on their child patients.
Describe the treatment effects of slow and rapid maxillary expansion in the transverse, perimeter, vertical and antero-posterior planes of space.
Describe the success rates of posterior crossbite correction in the child patient.
