ORTHODONTIC-SURGICAL TREATMENT OF CLASS III MALOCCLUSION WITH EXTRACTION OF AN IMPACTED CANINE AND MULTI-SEGMENTED MAXILLARY SURGERY: AN 8-YEAR FOLLOW-UP

ABSTRACT Introduction: Skeletal Class III malocclusion is often referred for orthodontic treatment combined with orthognathic surgery. However, with the aid of miniplates, some moderate discrepancies become feasible to be treated without surgery. Objective: To report the case of a 24-year-old man with severe skeletal Angle Class III malocclusion with anterior crossbite and a consequent concave facial profile. Methods: The patient refused to undergo orthognathic surgery; therefore, orthodontic camouflage treatment with the aid of miniplates placed on the mandibular arch was proposed. Results: After 18 months of treatment, a Class I molar and canine relationship was achieved, while anterior crossbite was corrected by retraction of mandibular teeth. The consequent decrease in lower lip fullness and increased exposure of maxillary incisors at smiling resulted in a remarkable improvement of patient's facial profile, in addition to an esthetically pleasing smile, respectively. One year later, follow-up revealed good stability of results.

The Stability

OBJECTIVE: To evaluate the stability of bimaxillary surgery in patients with skeletal malocclusion, with the use of rigid internal fixation. METHODS: Lateral cephalograms from 20 patients, 11 males and 9 females, mean age of 26 years and 1 month, were evaluated before surgery, immediately post-operative and at least 6 months after surgery. Nineteen cephalometric measurements were evaluated, and the results were statistically analyzed by means of the Student's t test and the Kruskal-Wallis test. RESULTS: The Le Fort I maxillary advancement surgery showed almost no relapse. There was lack of stability of mandibular setback, with relapse of 37.33% on point B, due to counterclockwise rotation of the mandible between post-operative periods, occurred by better intercuspation after surgery and muscle adaptation. The results showed the same tendencies for both genders. CONCLUSION: It was concluded that on the bimaxillary surgery treatment of Class III malocclusion, the maxillary surgery was very stable, but the mandibular setback recurred. No statistical differences were found in surgical stability between genders.

Mandibular Protrusion

The purpose of this case report is to add another means of treatment for the anterior crossbite malocclusion in early mixed dentition. The selected functional device is an eruption guidance appliance (EGA). The analysed patient had a functional anterior crossbite, a mandibular protrusion tendency, and a normodivergent growth pattern. The early treatment was suggested to correct the malocclusion and avoid unfavourable occlusal conditions that could end in a class III malocclusion growth pattern. After 18 months of treatment, with night-time use, the malocclusion was completely resolved. This therapy strategy allowed the correction of the sagittal jaws’ relationship and maximum control of the vertical dimension. After 2 years of follow-up, the results were preserved. The peculiarity of this kind of intraoral orthodontic tools is the use of the erupting forces rather than the active forces. This early treatment of anterior crossbites with EGA may be considered an effective treatment approach for achieving good functional and aesthetic results.

Skeletal Class

In this report we describe a combined orthodontic and surgical treatment for a 14-year-old boy with severe skeletal class III deformity and dental problem. His upper posterior primary teeth in the left side were over-retained and 6 maxillary teeth (bilateral central incisors and canines, left first and second premolars) were impacted, together with 5 supernumerary teeth in both arches. The treatment protocol involved extraction of all the supernumerary and deciduous teeth, surgical exposure and orthodontic traction of the impacted teeth, a bimaxillary orthognathic approach including Lefort I osteotomy. Bilateral sagittal split ramus osteotomy (BSSRO) and genioplasty was performed to correct skeletal problem. After treatment, all of the impacted teeth were brought to proper alignment in the maxillary arch. A satisfied profile and good posterior occlusion was achieved. Treatment mechanics and consideration during different stages are discussed.

Viable Treatment

A search of the medical and dental records at Evidensia Lørenskog Dyreklinikk, in Lørenskog, Norway, was conducted to identify dogs that received temporary crown extensions (TCEs) to correct linguoverted mandibular canine (LMC) teeth over a 54-month investigation period (2012-2016). Criteria for inclusion into the study were the presence of complete medical and dental records, pre- and postoperative clinical photographs and intraoral radiographs of the affected canine teeth, adequate information pertaining to the procedures performed, and at least 1 follow-up >3 months after appliance removal. Seventy-two dogs with LMC teeth were treated with TCE. Thirty-nine breeds were represented in this study. Mean age at the time of appliance installation was 6.4 (range, 4.7-13.4 months [median, 5.9 months] months). Fifty-three (73.6%) dogs presented with class I malocclusion, 14 (19.5%) dogs with class II malocclusion, and 5 (6.9%) dogs with class III malocclusion. Twenty-five (34.7%) dogs were considered to have mild, 32 (44.4%) dogs to have moderate, and 15 (20.8%) dogs to have severe mandibular canine malocclusion. The TCE was combined with other treatment modalities (active orthodontics, extraction of nonstrategic teeth, gingivectomy, and inclined bite plane and ball therapy) to correct mandibular canine tooth malocclusions in 19 (26.4%) dogs. Fractured or detached crown extensions were seen in 9 (12.5%) dogs. Soft tissue ulceration or inflammation was seen in 7 (9.7%) dogs. The mandibular canine teeth occlusion resolved completely with self-retaining, functional, nontraumatic occlusion in 56 (77.8%) dogs. Fifteen dogs (20.8%) resolved with functional, nontraumatic occlusion, but the mandibular canine teeth were too short to be perfectly self-retained, thus left with 1- to 2-mm crown extensions for permanent retention. In 1 (1.4%) dog, both mandibular canine teeth relapsed almost back to original position. The results show that TCE is a viable treatment option to correct LMC teeth in young dogs.
