JVD · Increased Overjet Appliance
Designed for childhood increased overjet and bite-guidance needs associated with mandibular retrusion. Jaw-positioning features and tongue guidance provide an auxiliary option for early orthodontic care.
Design & structure
Upper and lower jaw-positioning features, a tongue guide and small bilateral tongue supports assist forward mandibular guidance and tongue-position training, while addressing associated deep bite and Class II occlusal relationships.
Clinical use & follow-up
Intended for individualized auxiliary management of increased overjet and Class II malocclusion associated with mandibular retrusion. Follow the clinician’s prescribed wear schedule and attend regular reviews.
