A compact orthodontic bracket that employs a simple method of self-ligation, is compatible with both permanent and deciduous teeth and is less expensive to manufacture than existing commercial brackets. The bracket utilizes a rotary plate that covers an arch wire slot when closed and can be pivotably opened to allow arch wire changes. Ligation may also be augmented using conventional ligatures on the paired tie wings. The simplicity of the ligating mechanism allows manufacturing of a smaller bracket. It is also less vulnerable to the clogging effects of salivary deposits than commercial self-ligating brackets currently in use.
