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.
