[Treatment of deep anterior overbite by using the fixed appliances in conjunction with a small bite plate].
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.


CONCLUSIONS
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.
