[Treatment of deep anterior overbite by using the fixed appliances in conjunction with a small bite plate]
1Department of Orthodontics, Guangdong Provincial Stomatological Hospital, Guangzhou 510260.
Objective:
This study was to investigate the effective method in the reduction of deep anterior overbite.
Methods:
Twenty-nine cases of three-degree deep anterior overbite were treated by using the fixed appliances in conjunction with a small bite plate.
Results:
It was showed that this method was significantly quicker to reduce deep overbite of anterior teeth (2.04 +/- 0.78 mm per month) and shorter to require the time of treatment (3.94 +/- 1.55 months) than that by using the single fixed appliances (P < 0.001), and there was no significant difference between the adults and juveniles. These findings suggest that it was effective for both of adult and juvenile patients.
Conclusion:
As the destruction of molar tubes, wire and bracket bonding failure caused by bite were less happened, it was effective to treat complicated cases of deep overbite with a shorter occlusogingival distance, posterior cross-bite and not enough alveolar highness of posterior teeth who could be difficult to treat by a routine method.
