Final answer:
To prevent the lower anterior teeth from flaring or dumping while using the Carriere Motion II appliance, Dr. Luis Carriere advises the use of additional support like a lingual arch. This helps maintain proper tooth alignment and ensure successful orthodontic treatment.
Step-by-step explanation:
When using the Carriere Motion II intraoral appliance, Dr. Luis Carriere recommends using support such as a lingual arch or fixed lingual retainer to prevent the lower anterior teeth from dumping or flaring. It is important to stabilize these teeth because the force applied during orthodontic treatment can cause them to shift in ways that are undesirable, such as tilting forward (flaring) or moving downwards (dumping), potentially affecting the treatment outcome.
The intraoral appliance works by applying forces to correct the bite and alignment of the teeth. This is similar to the forces applied by braces, which are used to realign teeth by applying tension to guide teeth into their corrected positions. Ensuring that the lower anterior teeth are properly supported helps maintain their position and the overall harmony of the dental correction achieved with the treatment.
