Podcast episode (Untethered Podcast Ep. 333) in which host Hallie Bulkin interviews Dr. Svitlana Koval about MARPE (miniscrew-assisted rapid palatal expansion) with a focus on airway improvement, facial development, procedural variants (screw designs and guided piezo corticotomy), treatment planning with aligners, and practical patient expectations. Key takeaways: guided 3D piezo corticotomy + MARPE aims to split the palatal suture fully (ANS→PNS) to widen nasal passages and laterally expand pharyngeal airway; typical expansion course for adults is ~8–10 weeks with the appliance retained 6–7 months (some central palatal fusion may continue to 10–12 months); target midline bone separation often cited as 3–5 mm; specific screw used in the practice produces 0.1 mm per turn (other screws may produce 0.2–0.25 mm/turn); overall orthodontic treatment and mandibular advancement planning commonly extends to ~2 years; age cutoff for preferring screw-retained appliance vs pediatric expander is roughly 10–11 years. Practical notes: procedure ~30 minutes in-office under local anesthetic; no turning for ~1 week post-op while soft tissues heal; avoid Waterpik first week and follow saline rinses; aligners (including direct-printed aligners) used for post-expansion tooth movement to avoid undesirable retraction.

Questions this video answers

0.1 millimeters per turn (1/10 mm per activation).

Other MARPE screws may produce 0.2 or 0.25 millimeters per turn.

About 8–10 weeks on average.

About 6–7 months (research commonly cites ~6 months).

Around 10–12 months for the central midpalatal region to fully mature in some cases.
