| Abstract |
|
Early identification of maxillary canine impaction is very important, because of treatment duration time. Analysis used by 3-dimensional computed tomography is more important than before in treatment planning. The aim of this study was to analysis of factors associated with the treatment during time of forced eruption of the impacted maxillary canine using 3-dimensional computed tomography. 17 patients were analysed in Daejeon dental hospital of Wonkwang university(16 patients with unilateral impactions and 1 patient with bilateral impaction). In total, 18 maxillary impacted cannines were analysed by 3-dimensional computed tomography. The results obtained were as follow; 1. There was positive correlation between the age of patient and treatment duration time. 2. There was positive correlation between the distance of occlusal plane to cusp of maxillary impacted canine and treatment duration time, and negative correlation between the length of maxillary impacted canine and treatment duration time. 3. There was positive correlation between the angulation of midsagittal plane to axis of maxillary impacted canine and treatment duration time, and negative correlation between occlusal plane to axis of maxillary impacted canine and treatment duration time. In conclusion, age, tooth length, distance from the canine cusp tip to the occlusal plane, angulation of tooth axis to occlusal plane and midsagittal plane allow that we can predict treatment duration time. |
