The impacted teeth were surgically exposed by the closed-eruption technique and orthodontically retracted. The subject of this study are 24 patients(Mx. insiors; 10 Mx. canines; 14) who finished their treatment. The periodontal condition of the impacted teeth and the normally erupted proximal and opposed teeth were compared and analysed. The results are the followings ;
1. When the gingival index, plaque index, pocket depth and attached gingiva in periodontal evaluation were compared, there was no significant difference between the study group and the control group (P>0.05).
2. When the alveolar bone support of the mesial and the distal surface of the maxillary central incisors and proximal teeth was compared, there was no significant difference between the study group and the control group (P<0.05).
3. When the alveolar bone support of the maxillary canines was compared, there was no significant difference between the retracted teeth and the normally erupted teeth(P>0.05).
The results above showed that the surgical exposure by closed-eruption technique followed by the orthodontic retraction of the impacted teeth has a positive influence on the regeneration of gingival tissue in clinical practice and is esthetically more stable. And it is considered that the clinicians should give attention to the direction of retraction power and the maintenance of normal shape of the alveolar bone in treatment of maxillary central incisors.
