Functional appliances can be used as interceptive treatment options for young patients. Some benefits of interceptive treatment are:
• Reducing the risk of tooth crowding
• Creating facial symmetry through influencing jaw growth
• Space preservation for un-erupted teeth
• Elimination of 'crossbites', 'overbites' and 'underbites'
• Management of thumb sucking habits
A Twin block is a set of upper and lower removable plates that work together in conjunction with the patient's natural growth potential to correct jaw issues (malocclusions) such as 'underbites' and 'overbites'.
Upper Removable Appliance (URA)
Removable orthodontic appliances are appliances that are customized to fit your mouth to aid in your orthodontic treatment plan. Unlike braces and other types of appliances that are attached to your teeth, removable appliances can be taken out on your own as needed, such as when you are cleaning your teeth. Your treatment plan will be created for you by your orthodontist. In order to find the best plan of action to address the various stages that involve the adjustment of your teeth, you may require removable orthodontic appliances for the best results.
They can be used to correct minor orthodontic issues such as crossbites, expand narrow arches and slight individual tooth movements. Small screws can be inserted inside the plates in different places to perform these movements. Patients/ parents taught and advised to wind the screws themselves periodically to activate the tooth movement.Even Clear Aligners such as Invisalign aligners are a removable appliance.
