A Maxillary Skeletal Expander (MSE) is an orthodontic appliance that's an alternative to extensive surgical procedures. MSE is a non-surgical device for adults with a narrowed, high-angle palate, or upper and lower jaw discrepancy.

The MSE is capable of producing dramatic maxillary skeletal expansion. The expansion screws are available in 8mm, 10mm and 12mm stainless steel. The MSE uses 4 titanium alloy TADs for fixation to the palate and a wrench for activation.

Maxillary Skeletal Expander (MSE) is a specific type of Miniscrew Assisted Rapid Palatal Expander (MARPE), capable of producing large maxillary and midface expansion in young as well as in adult patients. It is indicated in the treatment of posterior cross bite, Class III malocclusions and it is able to improve nasal airflow and breathing.

MSE Can Be Used for Mature Patients. Contraindications. Extremely narrow palatal vault Patients with previous mid-facial trauma Extremely thick/dense palatal bone and/or dense buttress bone Extremely thin palate with low bone density. Activation Protocol. 4 Turns = 0.8mm(1 revolution)

MSE is considered a transverse parallel bone-bone expansion through bi-cortical engagement from the cortical bone. Success cases vary from unilateral/ bilateral crossbites, Class III to Class I, and even OSAS. Innovations in orthodontics from MSE inventor Dr. Won Moon is why this specialty appliance is one of a kind.

MSE has been widely accepted as a non-surgical skeletal expansion method for both pediatric and adult patients, particularly those experiencing airway constriction. The MSE expander screws are available in sizes of 8mm, 10mm, and 12mm.

The MSE II REPOSITION Kit contains: - 1 expander (8, 10 or 12mm) - 4 micro screws (1.8-9mm / 1.8-11mm or 1.8-13mm) - 2 Activation Key MSE

2022年6月16日 · MSE扩弓器扩弓利用4颗支抗钉辅助上颌扩弓，在原有的螺旋扩弓器基础上增加种植支抗装置，最大程度的增加骨性扩弓的效果，并且最大限度的减少了常规扩弓可能带来的副作用，如颊向牙槽骨高度降低、后牙颊倾现象、牙槽骨穿孔或开裂、复发等副作用。 MSE的生物力学机制不同于传统的扩弓方式,传统快速扩弓的扩弓原理是将扩弓力通过牙齿传递至腭中缝，MSE是通过固定在腭部的种植钉，把矫治力传递到腭中缝，扩弓器通过克服腭部骨组织的锁结力，将腭 …

Developed by Dr. Won Moon, the Maxillary Skeletal Expander is a version of the Microimplant Assisted Rapid Palatal Expander (MARPE). The MSE is capable of producing dramatic maxillary skeletal expansion for patients of any age. The MSE uses four temporary anchorage devices (TADs) for fixation to the palate and a wrench for activation.

MSE is a non-surgical device for adults with a narrowed, high-angle palate, or upper and lower jaw discrepancy. They can correct narrow upper jaws among older patients in a non-invasive manner by placing four titanium alloy TADs in the palate, then using a wrench for activation.
