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.
When braces put pressure on one's teeth, the periodontal membrane stretches on one side and is compressed on the other. This movement needs to be done slowly or otherwise the patient risks losing his or her teeth. This is why braces are worn as long as they are and adjustments are only made every so often.
