Duccio di Buoninsegna (Italian: [ËduttÊo di ËbwÉninËseÉ²É²a]; c. 1255â1260 â c. 1318â1319) was an Italian painter active in Siena, Tuscany, in the late 13th and early 14th centuries. He was hired throughout his life to complete many important works in government and religious buildings around Italy. Duccio is credited with creating the painting styles of Trecento and the Sienese school, and also contributed significantly to the Sienese Gothic style.
In some situations, to maintain the bite, the orthodontist will not want the back teeth to come forward. The headgear serves to hold them back (maintain anchorage). Orthodontists will want those patients to wear the headgear as much as they can. Realistically for most adults this might only be 8-10 hours per day, but the more the better; even 24 hours would be acceptable. Soreness of teeth when chewing, or when the teeth touch, is typical.
Orthodontic headgear is attached to equipment within the mouth, such as a facebow. The facebow is connected to the braces themselves, usually to brackets, bands, and buccal tubes in the mouth. The headgear anchors to the head by thin metal arches and straps. These pieces transmit force to the facebow.
