MISMARPE / DOME what is it?
Join me for a look at maxillary expansion combining both surgery with miniscrews. Seemingly opposite ideas have been brought together to offer potentially greater versatility in expansion, with less surgical complexity andcomplications.

Or
DOME Distraction Osteogenesis Maxillary Expansion Liu2017
Protocol
· Osteotomy
o Anterior vertical incision interdental toperiform fossa
o Lateral incisions to the base of zygomaticprocess of maxilla
o Without releasing the pterygomaxillary suture
o Activate in surgery up to 20x ensure diastema
o Duration 24 minutes (14.4-32) Junior 2021
o Less pain – Mild on VAS
· Expansion
o 7 days no expansion
o Expansion of rate 0.25 - 0.50 mm,
§ Some until diastema and slow to 0.25 per day
Advantages
· Less osteotomies required
· Under sedation or local anaesthetic
· Greater anchorage for force delivery throughminiscrews
· Less intra-operative haemorrhage – due to a lackof pterygopalatine disjunction
· Parallel expansion – Lin 2015 Vs V shapeexpansion
Age
Limitation of MARPE was age, with 20-30 years females 94% 20-30years males 80%, MARPE success 30-37 = 20% Olivera 2021, MISMARPE 96% successage 20-59, 24 patients majority over 30 years old Piccoli 2023.
Expansion amount
· Direct comparison show no significant differenceda Silva 3mm, and no difference in molar angulation 2023
Indicated for:
· Failed MAPRE
· Age- greater 30 females and 25 for males
Could MISMARPE / DOME replaceSARPE?
