Join me for Sarah’s lecture looking at her management of trauma, hypodontia and molar incisor hypomineralisation




o   UK evidence base – usually for crossbites only

o   US – encourage expansion in ‘phase 1’

o   Difference = cultural clinical practice


Deciduous trauma

o   Dilacerated and horizontal upper incisor

o   Guidelines on impacted central incisors RCS

o   Exposure and bonding

o   Aligned

§  URA followed by sectional fixed

§  If patient is willing, can consider attempt

o   Canines are more likely to be impacted

o   May require second course of orthodontics


Avulsion on adult teeth

o   Teenager with avulsed upper incisor, out of the mouth for 2 hours

o   Dental trauma guidelines – up to date guidance

o   Re-implant, but expect ankylosis

o   RCT and plan for decoronation


Luxation injury

o   Surgical repositioning

o   Orthodontic alignment



o   Removal of supernumerary and wait prior to orthodontic treatment


Molar incisor hypo mineralisation

o   Guidelines for extraction of first permanent molars in children RCS

o   Not an orthodontic decision, team approach to prognosis

o   Sarah delivers an orthodontic plan, and discusses prognosis of MIH separately

o   Extraction of 6s

o   May have impacted 8s, and require future orthodontics


Hypodontia patients

Dentally anxious patient with impacted canine

o   Address patients concerns of gaps, then extraction of C to allow 3 to come through


Impacted canine

o   50% resorption centrals, 60% lateral resorption

o   Leave 2s in situ

o   Exposure of canines

o   2s left in place until 3s vertically erupted

o   2s extraction and same day 3s built up – minimise aesthetic consequences



Patients not wanting lower arch treatment – patient taking control of enforced decision
