Which of the following is NOT a direction for use of the Balters bionator Type II?

• A. malocclusion of class II / 1 Angle
• B. malocclusion of class II I I
• C. deep occlusion
• D. laterognation

Answer: (C)

The Balters bionator Type II is a removable functional appliance aimed at guiding jaw growth and correcting Class II malocclusion by encouraging the mandible to posture forward and by altering the dental relationships to reduce overjet. It is used in cases where the main issue is an retrusive mandible (Class II) and can be effective in Class II Division I and Division II patterns, as well as in situations with mandibular position concerns such as laterognathism (mandibular shifting or asymmetry) where re-establishing a harmonious jaw relationship helps improve the occlusion. A deep bite, or deep occlusion, is a vertical problem where the upper teeth excessively overlap the lower teeth. The bionator’s mechanism focuses on sagittal (forward) jaw position and the resulting sagittal and rotational changes, not on correcting excessive vertical overlap. Treating deep bite typically requires vertical control or intrusion/extrusion mechanics that specifically address the bite depth, which is not the primary function of this appliance. Therefore, deep occlusion is not a standard direction for use of the Balters bionator Type II.
