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.
A brace can be made to fit the patient beautifully and to function perfectly, but is effectiveness will be lost if the orthotist has overlooked the correct construction of the shoe or the factors necessary for functional weight-bearing.
