THE EDITOR'S CORNER

The Most Challenging Cases

ROBERT G. KEIM DDS, EdD, PhD

An interesting question was posed to me recently in an interdisciplinary case conference at a university-based medical center dental school. These conferences are generally attended by specialists from other dental disciplines and occasionally by craniofacial, plastic, or ENT surgeons. Having been a practicing general dentist for almost 10 years before returning to school for orthodontic specialty training, I am frequently amazed at how little other health-care practitioners know about orthodontics and dentofacial orthopedics. This time, the question that caused my surprise was simply: “What are the most difficult malocclusions to treat?”

PEARLS

Remote Retainer Fabrication Using Teledentistry

NEAL D. KRAVITZ DMD, MS

The author details how a replacement retainer was prescribed by an office in Virginia for a patient attending a wedding in Arizona, using digital scanning and teledentistry. The same technique can be applied to a distant Invisalign patient who is in need of refinement aligners.

2017 JCO Orthodontic Practice Study Part 2: Practice Success

ROBERT G. KEIM DDS, EdD, PhD, EUGENE L. GOTTLIEB DDS, DAVID S. VOGELS III, PHILIP B. VOGELS

This month’s Practice Study installment examines management and practice-building methods that seem to be related to practice success, especially in terms of net income and numbers of case starts. Respondents are divided into three net income categories for purposes of comparison.

CASE REPORT

Anterior Open-Bite Correction with Miniscrew Anchorage and a Combination of Upper Lingual and Lower Labial Appliances

JAE HYUN PARK DMD, MSD, MS, PhD, KIYOSHI TAI DDS, PhD, MIWA IKEDA DDS

This report illustrates how anterior open bite can be corrected in a Class II case by combining upper lingual and lower labial brackets with miniscrew anchorage to achieve intrusion of the maxillary posterior teeth and consequent counterclockwise mandibular rotation.

The Easy Driver for Placement of Palatal Mini-Implants and a Maxillary Expander in a Single Appointment

ORONZO DE GABRIELE DDS, MS, GIANLUCA DALLATANA DT, ROBERTO RIVA DT, SIVABALAN VASUDAVAN BDSc, MDSc, MPH, BENEDICT WILMES DMD, MSD, PhD

This digitally produced insertion guide simplifies one-visit placement of a Hybrid Hyrax expander for early orthopedic treatment of Class III malocclusion. Alternating maxillary and expansion and constriction are followed by a protraction facemask in the example shown by the authors.

A New Appliance for Efficient Molar Distalization

VAIBHAV GANDHI BDS, MDS, FALGUNI MEHTA BDS, MDS, HARSHIK PAREKH BDS, MDS, MANOP AGRAWAL BDS, MDS

The Molar Thruster consists of a palatal acrylic covering with embedded Begg tubes, which are connected by bayonet wires to the palatal first-molar sheaths. Nickel titanium open-coil springs are compressed over the bayonet wires to deliver the distalizing force during the first phase of treatment.

Biocreative Torque-Maintaining Archwire for Adult Patients with Pathologically Migrated Incisors

KYUNG-YEN NAHM DMD, MDS, PhD, KEUM-AH HAN DDS, MSD, PhD, JAE-SUK JUNG DDS, MSD, PhD, KYU-RHIM CHUNG DMD, MSD, PhD, SEONG-HUN KIM DMD, MSD, PhD, GERALD NELSON DDS

The authors describe the application of flap surgery and upper incisor intrusion in adults with advanced periodontitis. A C-tube microplate is placed to anchor the intrusion, while a torque-maintaining archwire avoids labial flaring and a transpalatal arch minimizes reaction forces from the wire.
