中文摘要 | 恆牙第一大臼齒異位萌發常會造成第二乳臼齒牙根嚴重吸收、提早脫落並導致未來第二小臼齒空間喪失。本病例為一六歲男孩有雙側上顎第一大臼齒異位萌發合併第二乳臼齒牙根吸收,經過一個月Halterman appliance治療,雙側異位萌發之第一大臼齒皆順利萌出,且牙根吸收之第二乳臼齒無任何症狀並且無明顯動搖度。 |
英文摘要 | Ectopic eruption of permanent first molars is defined as a disturbance of eruption with a mesial eruptive path which result in the permanent tooth impacted under the distal undercut of the second primary molars. Untreated irreversible ectopic eruption of first permanent molars may cause delay eruption or impaction of permanent first molars, excessive root resorption or premature loss of primary second molars, and space deficiency of second premolars. This case report describes the treatment of a 6-year-old boy with ectopic eruption of bilateral maxillary permanent first molars. After one months of bilateral permanent first molars distalization by Halterman appliances, the ectopic erupting first molars had been corrected and the resorpted primary second molars still retained and without symptom nor mobility. |
