Eugene L. Gottlieb, DDS, Founding Editor of JCO, died Oct. 11 at his home in Sedona, Arizona, at age 99. In an extended Editor’s Corner, Executive Editor David Vogels paints a portrait of a long and eventful life.
In this article, Dr. Carmen Lorente and four colleagues illustrate an effective and simple surgical technique, using a cantilever arm supported by a miniscrew and a dental anchorage unit, to force the eruption of a deeply impacted second molar.
A second-generation palatal expander avoids problems associated with the activation key by using an integrated arm operated with a finger. It can be fabricated with two support arms for a patient in the mixed dentition or with four support arms for enhanced stability in the permanent dentition.
In the concluding installment of this six-part series, Dr. Chung and colleagues demonstrate their approach to Class III cases. Their small, I-shaped C-tube microplate can be custom-fit in the retromolar area to anchor efficient mandibular-arch distalization.
Drs. Spitz, Gribel, and Marassi describe the application of computer-aided design to position brackets and to design and fabricate transfer trays for indirect bonding, using a 3D printer. The procedure is illustrated in a 13-year-old female patient.
The combination of mandibular prognathism with anterior open bite in an adult patient has traditionally required surgical-orthodontic correction. As this case shows, skeletal anchorage now enables orthodontic molar intrusion to close the open bite by counterclockwise mandibular rotation.
Extraction spaces often reopen within a year following orthodontic treatment. This Pearl presents a simple modification to a wraparound retainer, using a cinched nickel titanium wire in the labial bow, that can close a relapsed space in the lower arch during retention.
