Case planning
For every Fan-Type Expander, the prescribing clinician should assess the dentition, periodontal condition, skeletal pattern, occlusion, tooth position, soft tissues, temporomandibular joints, oral hygiene, patient cooperation, and treatment objective. The design and activation or wear schedule must follow the approved prescription. Appliance categories are not automatically interchangeable because fixed and removable designs place different demands on anchorage, compliance, hygiene, adjustment, monitoring, and maintenance.
