CASE REPORT
Herbst Appliance Supported by Four Miniscrews
Volume 53 : Number 12 : Page 737 : Dec 2019
The Herbst appliance, although reliable and well tolerated, has been associated with such adverse dental effects as proclination of the lower incisors and palatal inclination of the upper incisors. Drs. Manni, Cerruto, and Cozzani employ skeletal anchorage from four miniscrews to mitigate these effects.

Evaluation of Mandibular Position for Splint Therapy Using a Virtual Articulator
Volume 54 : Number 8 : Page 466 : Aug 2020
Digital technology offers an alternative to the traditional articulator and facebow transfer used to confirm condylar stability during stabilization splint treatment. In this virtual mounting method, sequential mandibular positions are evaluated based on superimposition of the initial CBCT data with intraoral scans taken at each visit.

Volume 55 : Number 1 : Page 11 : Jan 2021
Dr. El-Bialy describes the combination of PBM with the Invisalign mandibular advancement feature in adult patients. In certain cases, this approach may avoid the need for extractions or orthognathic surgery. The protocol is illustrated in an adult female who was treated in only seven months.

3D Digital Applications of the Modified C-Palatal Plate for Molar Distalization
Volume 55 : Number 12 : Page 773 : Dec 2021
Modified C-palatal plates have been developed as a palatal approach for Class II patients with severe overjet. Dr. Kook and colleagues demonstrate how to fabricate a 3D-printed jig and a new palatal retraction arch to improve placement accuracy, simplify removal, and avoid inflammation.
