Editor’s Note: The following guest editorial is offered as a counterpoint to the ADA recommendations summarized by Jackie Dorst in this month’s article on “Back-to-Work Coronavirus Infection Control”....
Jackie Dorst, a noted expert on infection control, discusses implementation of the ADA’s “Return to Work Interim Guidance Toolkit” in orthodontic practices. Topics covered include welcome back reassurance, pre-appointment screening, patient registration, reception area preparation, chairside procedures, and staff protection.
An anterior crossbite can be resolved with a fixed inclined biteplane, but those devices have drawbacks in terms of hygiene, speech, and mastication. This removable, vacuformed alternative uses a full dental arch as anchorage to correct a crossbite during Phase I treatment.
A 15-year-old patient with “kissing” lower canines is treated without surgery by extracting the horizontally impacted teeth and using a fixed functional Class II corrector to address the skeletal problem. The case is finished to a skeletal Class I and dental Class III relationship.
Drs. Lima and Freitas provide a rationale for using the marginal ridge as a guideline for bonding preadjusted brackets to the posterior teeth. The first premolars then serve as references for the anterior bracket positions. Two typical cases are shown.
In a prospective case-control study, Dr. Gaffuri and colleagues compare the efficacy of clear aligners with that of preadjusted edgewise appliances in premolar-extraction treatment, as scored by the ABO Objective Grading System and ABO standard cephalometric analysis.
Sliding jigs can now be combined with temporary anchorage devices to optimize biomechanics for unilateral Class II correction. The authors describe how to fabricate an efficient, esthetic, and inexpensive jig from beta titanium or stainless steel wire.
