Manage episode 332303246 series 2830917
Join me for a summary of early treatment lectures from this years AAO meeting from May 2022. Topics will cover trauma, airway diagnosis and orthodontic treatment, and optimal timing of class 2 correction
Lectures:
- Dental Trauma Eustaquio A. Araujo
- Airway-centered Orthodontic Diagnosis & Treatment for Pediatric Patients Hong He
- Predictors of Success for Early Mixed Dentition Treatment Heesoo Oh
Dental Trauma Eustaquio A. Araujo
Trauma protocol
- Reposition with firm grip
- 16x22NT
- Bite props to eliminate occlusal interference
- Soft diet
- Recall 2 weeks
Re-implantation of avulsion success
- Less than 1hour 75%
- Up to 24 hours 25%
- Conclusion – look at the neighbours
Airway-centered Orthodontic Diagnosis & Treatment for Pediatric Patients Hong He
Nasal breathing Vs mouth breathing
- NB = Tongue rests on the palate. MB = Tongue floor of the mouth
- NB = Pressure of the cheeks is balanced with the tongue. MB Pressure of the cheeks is unopposed by tongue
- NB = U shape upper arch (normal). MB = V shaped arch
Tonsillar hypertrophy
- Oropharynx obstruction
- Ventilation impaired
- Occlusal effects
- Tongue and mandible forwards Iwasaki 2017
- Mandibular protrusion
- Class 3 malocclusion
- He’s study n=1776
- Greater tonsillar hypertrophy in children with class 3
Caution as limited studies pre-pubertal and controls also improved in scores
Predictors of Success for Early Mixed Dentition Treatment Heesoo Oh
When is it best to treat class 2 cases
Study: optimal timing of the effectiveness and efficiency
- Early class 2 equally effective not as efficient
- BUT
- Mean changes = mask individual response
- Philosophy – correct some / all features of malocclusion
- Reduce / eliminate need for phase 2
- Angle orthodontist Oh 2017
Treatment protocol
- 7-9 years
- Headgear night wear 11 hours
- RME
- 2 x 4 fixed appliances
- Lingual arch
- Greater 33 months = unsuccessful (time only marker of success, as occlusal and skeletal the same at the end)
Results
- 15/54 (28%) phase 1 only
- Comparison
- No differences in occlusal and skeletal outcomes
- Time
- Total treatment times (phase 1 + phase 2):
- 67% less than 18 months in treatment active treatment
- 20% 4-5 years of total treatment time
- Total treatment times (phase 1 + phase 2):
