Surgical Treatment Phase

  • Surgeries for maxillary deformity
  • Surgeries for mandibular deformity
slide15

Surgeries for maxillary deformity

  • Segmental osteotomy (Anterior / Posterior)

Indications:

- maxillary protrusion

- marked protrusion of maxillary teeth

- open bite

slide16

Surgeries for maxillary deformity

  • Le Fort I osteotomy (total or segmental)

Indications:

- maxillary deformities

- mandibular deformities

slide17

Surgeries for maxillary deformity

  • Le Fort I osteotomy
  • Le Fort II or III osteotomy

Indications:

- midface deficiency

Surgeries for mandibular deformity

  • Sagittal split ramus osteotomy, SSRO

Indications:

- mandibular excess

- mandibular deficiency

- mandibular asymmetry

slide20

Surgeries for mandibular deformity

  • Vertical ramus osteotomy

Indications:

- mandibular excess

- mandibular asymmetry (combined with SSRO)

back

slide21

Surgeries for mandibular deformity

  • Subapical osteotomy

Indications:

- bimaxillary protrusion / open bite

- leveling the plane of occlusion

- uprighting anterior teeth

slide22

Surgeries for mandibular deformity

  • Body osteotomy

Indications:

- mandibular excess (body) combined with ramus procedure or not

- open bite / spee’s curve reduction

slide23

Surgeries for mandibular deformity

  • genioplasty

Indications:

- chin deformities

  • Bleeding
  • Infection
  • Necrosis of teeth / bone
  • Healing
  • Injury of nerve
slide25
