While claims of the popularity of different appliances are always a little suspect—usually due to a lack of rigorous scientific method in the survey—it cannot be denied that the Herbst appliance is on...
Dr. Ojima and colleagues describe three methods of correcting anterior open bite with the Invisalign system, depending on the clinical situation. Biomechanics are illustrated for cases requiring various combinations of anterior extrusion, molar intrusion, and maxillary molar distalization.
The conclusion of this three-part report examines practice growth in terms of case starts and gross income over the past two years, as well as expectations for the next two years. Staff employment patterns, salaries, and benefits are also covered.
The original Loca-System used a loop of rectangular superelastic nickel titanium wire to distalize maxillary molars. This modification of the loop can be used to recover and upright a deeply impacted mandibular second molar, as demonstrated in an adult patient.
The authors introduce FlashCure, a light-emitting diode unit that can cure composite on multiple teeth at the same time. An in vitro test shows greater shear bond strengths from the prototype FlashCure device than from a commercially available light-curing unit.
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.
Dr. Lee shows how to use Class III elastics, attached from a maxillary expander to buttons on the lower lateral incisors, and a lower Essix retainer to correct an underbite during Phase I interceptive treatment without headgear.
