Distalization and expansion with Ortho Easy System miniscrews. From insertion to activation. All benefits and tricks

Today the number of publications and courses about skeletal anchorage, is great and it would seems that miniscrews are ubiquitous. Surely, anchorage control is important for efficient orthodontic treatment with fixed appliances too. The Ortho Easy system also offers lab abutments that can be used after palatal insertion of the miniscrews to take a transfer impression. The appliance can then be designed in the lab utilizing the abutments and placed at a later date. Appliances can be designed that focus all of the anchorage requirements on the miniscrews, leaving the maxillary dental arch (5-5) available for simultaneous treatment of other dental issues, such as alignment. These techniques are particularly effective for the distalization of upper molars and/or palatal expansion using hybrid RPE appliances. 

Initially, the Nance button of the standard Frog appliance was anchored using the mini-implants in the palate. The limited hygiene options of the palatal buttons, however, often resulted in the accumulation of food debris and localized irritation of the covered mucosa. This problem gave rise to the idea of developing an abutment that allowed direct connection of the mini-implant to the screw body. An abutment tailored to the Ortho Easy system can now be used as a transfer aid as well as a coupling and anchorage element.

Second important benefit of using miniscrews as an anchorage is elimination the need for dental anchorage and its undesirable side effects on the anterior arch as protrusion. Third great benefit is unilateral distalization , which is quite important in rehabilitation of adult patients with tooth loss.

With the miniscrews era standardized rapid palatal expansion appliance with combined dental and skeletal anchorage was developed. It is called the “Hybrid RPE” because it incorporates two anchorage techniques. Like skeletal distractors, the Hybrid RPE mainly keeps the anterior dental arch free to allow other treatment procedures to be performed simultaneously. The mini-implants are each placed about 2 mm lateral to the midpalatal suture to ensure that the rupture of the palatal suture is not impeded.


The Ortho Easy System is designed for classic vestibular interradicular insertion. A variety of auxiliaries are available to simplify treatment mechanics. The system also allows orthodontists to use palatal insertion, and lab abutments can be used to fabricate and connect a variety of laboratory-made appliances.
