深圳箍牙至佳年齡系咩

深圳箍牙至佳年齡系咩?一系乳牙合期:出現嘅乳牙排列唔齊或牙列反合(即地包天)同開合,就應該得到早期矯正,治療嘅年齡系3~6歲左右,此時,患兒嘅恆牙未萌出,乳牙嘅牙根未吸收,較穩固,可以通過戴用口腔內活動矯正器進行矯治,療程約6個月左右,早期治療對患兒頜面部嘅正常發育系大有益處嘅。如果唔可以及時矯正,喺呢一快速生長期內就有可能加重畸形。深圳箍牙至佳年齡系咩二系混牙合期:約莫系喺8~12歲,此時新生恆牙開始萌出,牙齒生長好快,咬合唔穩定,系牙齒畸形嘅多發期。主要原因系乳牙早失,導致牙弓長度減少,進而引起牙齒排列唔下,呢類患兒應做間隙保持器;乳牙早失使間隙關閉,導致恆牙冇足夠萌出空間引起牙齒畸形,要通過矯正器恢復間隙;唔良口腔習慣或嗜好導致嘅牙齒畸形,喺克服、改變唔良習慣嘅同時根據唔同情況,唔同程度可以從輕至重分別采用活動或固定矯治器,甚至配合口外整形力嚟糾正牙列。三系恆牙合期:乳牙已全部換完,第二顆大牙同第三顆大牙萌出時為又一個快速生長期,一般為12~18歲左右,呢時牙齒畸形嘅診斷比較明確,喺此快速生長期內矯正,速度快而且矯正效果穩定。
