ANALYSIS OF AN ORTHOGNATHIC CASE

The most common impacted tooth next to third molars

• Maxillary lateral incisors

• Maxillary canines

• Maxillary premolars

• Mandibular canines

Orthognathic surgery is indicated in

• Adult patient with severe skelatal discrepancies

• Children of 10 years of age

• Adolescent patient with mild skeletal discrepancy

• Adult patient with severe malocclusion

While evaluating the patient for Orthognathic surgeries anteroposterior cephalogram helps in

• To access the impacted tooth

• To access facial asymmetry

• Ankylosed teeth

• None of the above

While evaluating the patient for Orthognathic surgeries lateral cephalogram helps in

• To determine facial asymmetry

• In determining the nature and extend of Skeletal discrepancy

• To determine dental abnormalities

• Presence of impacted tooth

Decompensation refers to

• Repositioning of teeth properly over dental bone

• Alignment of crowded teeth

• Repositioning of teeth properly over the skeletal bone without consideration of bite relationship to the opposing arch

• All of the above

The following are Orthognathic surgical procedures for mandible except

• BSSM

• Vertical Ramus Osteotomy

• Lefort 1 Osteotomy

• Mandibular Subapical Osteotomy

The following are Orthognathic surgical procedure for maxilla except

• Segmental maxillary Osteotomy

• Anterior maxillary Subapical setback

• BSSM

• Lefort 1 Osteotomy

Skeletal discrepancy with maxillary deficiency of maxilla can be treated by

• BSSO

• Lefort 1 Osteotomy with maxillary advancement

• Segmental maxillary Osteotomy

• Transoral vertical Osteotomy

Presurgical Orthodontics is aimed at

• Done before Orthognathic surgeries

• Correcting the dental compensation that has occured in response to skelatal deformity

• Done after Orthognathic surgeries

• Both A and B

After presurgical Orthodontic tooth movement

• The skeletal discrepancy is accentuated

• The skeletal discrepancy gets corrected

• Dental malocclusion gets corrected

• All of the above
