Treatment: LS Increased overbite
Not corresponding to Angle classes
with growth
Treatment principle: “Dentofacial/orofacial orthodontics and dental: shorten anterior region
(intrusion), elongate posterior region (extrusion)”
Skeletal overbite: horizontal growth pattern (hypodivergent, brachyfacial)
 Angle class II: functional orthodontic forward movement of the mandible, alveolar vertical
development of maxillary and mandibular posterior region, prevention of vertical elongation
of anterior region (“relative intrusion”): UBA 1, FR 2, (MB)
 Angle class III: therapeutic prevention of mandibular growth = mandibular posterior
rotation: skeletal bite opening: FR 3, UBA 2
 Encourage maxillary growth: anterior maxillary rotation
 Delaire mask (note: direction of the elastics from the maxilla to the mask = from up to down,
possibly parallel, as desired bite opening.)
 Angle class I: prevent anterior vertical alveolar development (“relative intrusion”), active
intrusion of upper and lower anterior teeth (depending on soft tissue findings: note lip-tooth
relation): UBA 1 in centricity, MB: segmented techniques
Dental overbite
 Intrusion of anterior region, posterior extrusion, leveling of Spee curve, proclination of
anterior region (“relative shortening”), depending on sagittal position (Angle class I, II, III):
UBA type 1, FR 2 or 3, MB
Vertical compulsive bite (overclosure)
 “Supporting the vertical dimension”: overclosure
 With mandibular prognathic overclosure: FR3, head chin cap, MB
 Loss of multiple posterior teeth (deciduous, permanent): preserve or restore bite elevation:
UBA, children’s prostheses, later prosthetics, implants, vertically stable fillings (inlays)
