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)
