[Removable appliance and closed of central incisors: report of 48 cases].

Purpose: To evaluate the treatment effect of orthodontic traction on embedded and inverted maxillary bending central incisors.

Methods: Fifty-two embedded and inverted maxillary central incisors without-eruption ability in 48 cases were treated by combined orthodontic traction with surgical treatment after spiral CT positioning and expanding the space, the eruption situation, gingival-breaking time and teeth pulp vitality after treatment were recorded, and the treatment effect was evaluated.

Results: Forty-eight cases with 52 impacted upper central incisors were treated with surgical and closed orthodontic traction, successful results were achieved in 36 cases, accounting for 69.

[Expression of MMPs in gingival crevicular fluid of the rats in different age groups with orthodontic appliances].

Purpose: To detect the changes of MMP-1 and MMP-9 in gingival crevicular fluid (GCF) of the rats in different age groups with orthodontic appliances.

Methods: 40 female Wistar rats were selected as the animal model, in which there were 20 6-week-old rats and 20 12-week-old rats. The orthodontic appliances were fixed onto the maxilla of the rats after general anesthesia.
