(1) Background: This retrospective study aimed to examine the change of gingival recessions (GR) before and after orthodontic treatment (OT). (2) Methods: Patients who had at least one GR on the vestibular surface of maxillary/mandibular teeth mesial to first molars were included. GR was measured on good quality plaster models before and after OT. (3) Results: Significant improvement of mean GR at patient level was found between T0 and T1 (0.45 mm, 95% CI: 0.28, 0.62) (p < 0.001). In 51.4% of patients GRs became better, in 37.8% GRs did not change. and in 10.8% GRs became worse. At tooth level the mean GR improvement was 0.54 mm (CI: 0.42, 0.65; median 0.55 mm Q1; Q3: 0.12, 0.96) (p < 0.001). GR improved in 67 teeth (58.7%), did not change in 41 (36.0%), and worsened in 6 (5.3%). Full healing was observed in 15 teeth. A reduced GR improvement was found in cases with pre-treatment open bite (OR 3.89; CI: 1.35, 11.16; p = 0.008) and dental Class III patients (OR 2.6; CI: 1.11, 6.0; p = 0.026). (4) Conclusion: There was an improvement of GR after OT in more than half of the patients. Class III malocclusion and reduced pre-treatment overbite had a negative impact on GR improvement.

Abstract Background: The development of gingival recessions (GR) after orthodontic treatment (OT) is well described in the literature. However, there is a lack of information about the changes in pre-existing GR during OT. Methods: This retrospective study aimed to examine the change of GR before and after OT. Intraoral photographs of 993 patients treated with fixed appliances between 2005 and 2017 were evaluated. Patients who had at least one GR on the vestibular surface of maxillary/mandibular teeth mesial to first molars were included. GR was measured on good quality plaster models before and after OT. The change of GR (T0-T1) was categorised into the three groups: worsened, did not change and improved (this group consisted of GR, which became better but did not disappear, and fully healed, which disappeared after OT)). The change of GR by ≥0.5 mm was recorded. Statistical analysis was performed using SPSS Statistics (Version 22.0. Armonk, NY, USA). Results: Fifty-one (5.1%) patient had ≥1 GR before OT. Of them, 37 (72.5%) patients were included in the final analysis according to the inclusion criteria. GR before OT was found on 114 buccal/labial surfaces. At tooth level the median GR improvement was 0.55 (Q1; Q3: 0.12; 0.96) mm (p<0.001). GR improved in 67 teeth (58.7%), did not change in 41 (36.0%), and worsened in 6 (5.3%). Of the 67 GR, which improved, full healing was observed in 15 (22.4%) teeth. There was a lower chance for GR improvement in cases with pre-treatment open bite (OR 3.35; 95% CI: 1.14, 9.84; p=0.03) and dental Class III patients (OR 2.20; 95% CI: 0.92, 5.28; p=0.03). Conclusions: Based on the findings of the present retrospective study, it may be concluded that orthodontic treatment induces changes in gingival recessions. In more than half of the teeth, the improvement in gingival recession was observed. Class III malocclusion and reduced pre-treatment overbite had a negative impact on GR improvement.

Clinical Interest

We report a 16-year-old boy who had all the typical manifestations of achondroplasia but also had a skeletal and dental class III malocclusion, a narrow maxilla, macroglossia and an open bite between the posterior teeth. The narrow maxilla and bilateral cross-bite were treated with rapid palatal expansion. The open bite and irregular teeth were corrected with fixed orthodontic treatment, taking account of the macroglossia. This case is of clinical interest since dental class III malocclusion, posterior open bite, macroglossia and benign migratory glossitis have not previously been reported in achondroplasia.

ABSTRACT The present case report describes the orthodontic treatment of a young adult patient (18y / 1m), Class III skeletal malocclusion, with mandibular prognathism and significant dental compensation. The canine relation was Class III, incisors with tendency to crossbite and open bite, moderate inferior crowding, and concave profile. Skeletal correction of malocclusion, facial profile harmony with satisfactory labial relationship, correction of tooth compensation and normal occlusal relationship were obtained with orthodontic treatment associated to orthognathic surgery. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as part of the requirements to become a BBO diplomate.

ABSTRACT A 29-year-old female patient with unilateral condylar hyperplasia (UCH) of the left side presented with facial asymmetry, maxillary transverse occlusal plane (MXTOP) cant, posterior open bite, and Class III relationship. Treatment consisted of proportional condylectomy of the left condyle for management of UCH, and fixed orthodontic treatment with intrusion of the left maxillary molars to correct the MXTOP cant and remaining chin point deviation (CPD). Proportional condylectomy with a 14-mm resection of the left condylar head improved the CPD from 11.5 mm to 7.8 mm and resolved the posterior open bite on the left side. However, it produced a Class II relationship on the right and left sides, posterior open bite on the right side, and anterior open bite. Fixed orthodontic treatment with 1.8-mm intrusion of the left maxillary molars using miniscrews corrected the MXTOP cant from 3.5 mm to 1.7 mm, reduced the remaining CPD from 7.8 mm to 3.7 mm, produced counterclockwise rotation of the mandible, and resolved the posterior open bite on the right side and the anterior open bite. After 16 months of total treatment, normal overbite/overjet and Class I relationship were obtained. Treatment results were well maintained after 5 years of retention. For the correction of UCH, it is important to determine the amount of condylar head resection and accurately simulate the correction of CPD and MXTOP cant through intrusion of the maxillary molars.

Setting: College of Dental Surgery, B P Koirala Institute of Health Sciences, Sunsari, Nepal. Aims: To evaluate the pattern and distribution of malocclusions in patients seeking for orthodontic treatment from Sunsari district of Nepal. Material and Methods: Total of 350 patients who were permanent inhabitants of Sunsari district of age range 8-36 years were included in the study. A standard format was prepared to record the data. Descriptive statistics for mean, standard deviation and frequencies were calculated. Ages and Class I, II and III malocclusions were cross tabulated to check for any relationship using ANOVA. Intra investigator error was calculated using kappa statistics. Results: The prevalence of Class I, II and III malocclusions were 62.28 %, 29.4%.and 8.2% respectively. Out of 350 cases studied for various occlusal traits the nature of distribution of various occlusal findings were: absent teeth-12.6%, supernumerary teeth-2.9% ectopic eruption-7.1%, midline diastema-16%, incisor crowding-52.9%, spacing-30%, malformations-3.1%, increased overjet (>4mm)- 42.3%, anterior open bite . 5.1% and deep bite (>4mm )- 40 % and cleft lip and palate was 0.28%. Most prevalent age group seeking orthodontic treatment was 12-24 years with females to male ratio of 2.3:1 Comparison of mean ages with different malocclusion groups using ANOVA was statistically not significant. Conclusion: Class I malocclusion was the most prevalent followed by Class II malocclusion and the Class III malocclusion showed least prevalence. There were diverse occlusal traits.
