Orthodontic correction for dogs is both practical and beneficial. We have treated several dogs in our practice and have developed a manageable, fully fixed technique for solving various malocclusions. The case presented herein was a pseudo Class III malocclusion with all incisors in crossbite and an anterior open bite. (AM J ORTHOO DENTOFAC ORTHOP 1990;98:19-21.)
CASE REPORT Barney, a 9-month old Scottish terrier, was brought to our office because of the owner's concern for Bamey's developing malocclusion. Examination showed that Barney exhibited a pseudo Class III malocclusion with all incisors in crossbite and an anterior open bite (Fig. I). The treatment plan consisted of labially repositioning the maxillary anterior teeth while retracting the mandibular anterior teeth. No buccal segment correction was necessary. Barney was premedicated for all his visits with two 10 mg tablets of promazine ingested 1 hour before each appointment, followed by two 10 mg tablets taken in the office (as per veterinarian's recommendations). Impression trays were custom fabricated by cutting out *Past Associate Professorof Orthodontics at Boston University;currently in private practice. **ClinicalAssociateof Orthodontics, Universityof Pennsylvania;Guest Lecturer, Tufts University. 814/10415

in the standard fashion. Intraoral photographs were taken next. The appliances were made by pinching and fitting maxi]lary and mandibular bands on the canines. Impressions were taken again with the bands in place; the bands were then removed and seated back in the impression, which was poured in stone. On these working casts, Barney's appliances were fabricated. The appliances consisted of 0.030-inch base wires soldered to the prefit bands with two 0.016-inch stainless steel wires, soldered as finger springs to the distal aspects of the base wire adjacent to the bands (Figs. 2 through 5). Barney was seen at 3-week intervals during the active treatment phase of 3 months' duration. All adjustments were made either intraorally with light wire pliers (Fig. 6) or, as
occasionally required, by the removal of the appliances to reshape the base wire and activate the fingersprings. Barney's owner was given a dental scaler and given instructions on maintaining good oral hygiene for Barney during treatment. Barney tolerated orthodontic treatment well although he occasionally broke the appliances with his paws. Posttreatment retention was considered unnecessary and 1 year after debanding, the orthodontic result was stable (Figs. 7 and 8). Reprint requests to: Dr. Jon M.
