Watch the “Bionator Appliance In Orthodontics” lecture presented by Dr Manase (Masters in Dental Surgery).
Why is this an important dental study video?
Bionators are functional, removable appliances that promote lower jaw growth. They can also be used to improve teeth positions in patients with an underdeveloped lower jaw.
Bionators are meant to be worn most of the time. Ideally, they should only be removed for cleaning, eating, playing sports, or when there is a risk of dental injury.
Timing is important when using functional jaw orthopedics, as studies have shown the therapeutic effectiveness of treatment is closely linked to the patient’s age.
The Bionators will generally provide the greatest benefit when used during the ascending portion of the pubertal growth spurt. They are suitable for patients aged seven years or older, with optimal results obtained while the patient is still growing.
Generally, these changes consist of retracting and positioning the maxillary incisors into a more upright position. Increases in mandibular molar eruptions are also possible.
This orthodontics lecture covers what the history, principle, treatment objective, advantages, disadvantages, indications and contraindications of a bionator.
Hoping that this orthodontics complete denture lecture helps add some value
