Week 4 Surgical-Orthodontic treatment Flashcards
Surgical-orthodontic treatment is for…
Severe skeletal malocclusions
True or False?
Not all skeletal malocclusion require orthognathic surgery?
True
Known etiology of Dento-Facial deformities
Facial syndromes and congenital anomalies
Postnatal growth disturbances: Trauma, endocrinal muscle dysfunction
Inherited tendencies: Mandibular protrusion
Environmental influences (Macroglossia)
Surgical solutions for Antero-Posterior Discrepancy
Le Fort 1: most common max procedure
BSSO: most commonly done mandibular procedure
Genioplasty: Tends to help either class 2 or 3 by either increasing or decreasing the prominence of the chin.
Long face characteristics
Vertical maxillary excess
Steep mandibular plane
short ramal height: short rami means high angle -> long face
Increased lower face height
An open bite
Short face characteristics
Vertical deficiency
Low mandibular plane
Decreased lower face height
often a deep bite
Transverse discrepancy surgical solutions
SARPE: for narrow maxilla
2-Piece Le Fort I
Mandibular midline osteotomy: not common
Distraction osteogenesis
what we use today to evaluate growth status
CVMS: cervical vertebral maturational system
Timing of surgery?
Postpone until growth is done!!
stages of combination of orthodontics with surgery
- Pre-surgical ortho
- Surgical
- Post surgical ortho
what do we do in pre-surgical ortho stage?
eliminate dental compensations
dental alignment
all procedures to facilitate optimal surgery
Goals of post-surgical orthodontics
Keep post-surgical orthodontics to a minimum: because by this time the patient is burnt out and wants to be done as soon as possible
