Common Problems

Skeletal Class II malocclusion with mandibular deficiency is one of the most common problems that patients seek treatment. Adult patients with severe skeletal Class II malocclusion need orthognathic surgery for successful treatment. Bilateral sagittal split osteotomy (BSSO) is the most often preferred technique for these patients. This case report briefs about two male patient of age 24 years presented with Class II Skeletal relation, mesoprosopic facial form, horizontal growth pattern and Angle’s Class II div 1 malocclusion who were treated with Bilateral sagittal split osteotomy (BSSO) mandibular advancement. The ideal anteroposterior relation was established along with a Class I molar, incisor, canine relationship and ideal overjet, overbite and the overall facial esthetics were significantly improved. Combined surgical-orthodontic treatment aims to obtain a more harmonious facial, skeletal, dental and soft tissue relationship with an added patient self esteem.

Leveling And Alignment

ABSTRACTBased on our literature search, we found that the use of miniplate anchorage with Forsus fatigue-resistance device (FRD) has not yet been reported. Therefore, the aim of the present case report was to present the treatment of a patient with skeletal Class II malocclusion with mandibular retrusion using Forsus FRD with miniplate anchorage. Fixed appliances with 0.022-inch slots were attached to the maxillary teeth and after 8 months of the leveling and alignment of the upper arch, 0.019 × 0.025-inch stainless steel archwire was inserted and cinched back. Two weeks after the placement of the miniplates bilaterally at the symphysis of the mandible, Forsus FRD was adjusted to the miniplates with a 35-mm length of rod chosen. Nine months after the skeletal anchored Forsus worn, Class I canine and molar relations were achieved and overjet was eliminated.

Mandibular Retrusion

Background: Mandibular retrusion is the main cause of Skeletal Class II malocclusion characterized by skeletal retrusion of mandible with skeletal or dentoalveolar protrusion of maxillary. Objectives: This study was conducted to evaluate effect of treatment with twin-block appliances on pharyngeal dimensions. Methodology: This study was conducted in in the Department of Orthodontics & Dentofacial Orthopedics in Kathmandu Medical College. Twenty patients of age group 7 to 14 years with skeletal class II malocclusion with mandibular retrusion were selected. Variables evaluated were depth of nasopharynx; height of nasopharynx; depth of oropharynx; depth of hypopharynx; soft palate length; soft palate thickness and soft palate inclination. The lateral cephalograms were obtained for all subjects before the start of treatment and after a follow-up period of approximately three months in treatment. Results: Results showed that depth of nasopharynx increased by 1 mm, height of nasopharynx increased by 0.78 mm, depth of nasopharynx increased by 1.97 mm, depth of hypopharynx increased by 0.79 mm, soft palate length decreased by 4 mm, soft palate thickness increased by 2 mm and soft palate inclination decreased by 7.01 mm. The results for depth of pharynx and soft palate thickness were statistically significant. Conclusion: This study concluded that the use of twin block appliance for class II patients corrects sagittal dimension of oropharynx and hypopharynx. Early intervention for mandibular retrognathism in class II malocclusion helps enlarge the airway dimensions and decrease potential risk of obstructive sleep apnea syndrome for growing patients in the future.

The Face

Orthodontic treatment of Class II, division 1 malocclusion in one or two phases is still controversial in contemporary Orthodontics. The present clinical case presents the orthodontic treatment of a 6-year-old patient with aesthetic complaint regarding the smile and bullying, presenting skeletal Class II, Class II malocclusion, Angle division 1, overjet with exaggerated protrusion of the maxillary incisors, exaggerated overbite with the lower incisors touching the palatal mucosa, absence of lip sealing and concave inferior face profile. In Phase I, rapid maxillary expansion was performed with Hyrax-type expander together with the Herbst fixed functional orthopedic device for 11 months. In Phase II, the fixed orthodontic appliance associated with intermaxillary elastics was used for 13 months. The two-phase treatment of Class II malocclusion, division 1 showed to be effective after 24 months, establishing adequate occlusal and functional results and improving the aesthetics of the lower third of the face.

Mandibular Retrusion

Background:Class II malocclusion is the most common sagittal skeletal discrepancy, with a prevalent skeletal pattern of mandibular retrusion. The correction of mandibular retrusion with functional removable appliance needs a good patient’s compliance; for this reason, some clinicians prefer to use no compliance apparatus.Objective:Objective of the present therapy note is to demonstrate that the use of no compliance apparatus can provide a good correction of skeletal class II malocclusion.Methods:In the present study, authors report a therapy note referred to a 10 years old patient, woman, affected by Class II, with mandibular retrusion and deep bite, treated in 2013 at the Dep. of Orthodontics of Messina University. An orthodontic treatment has been planned with the aim of stimulating mandibular growth; an Herbst appliance with a cantilever design, bonded on first maxillary and mandibular molars, has been used. After eleven months of functional therapy a bilateral molar class I have been obtained.Results:In the therapy note proposed, authors obtained a resolution of mandibular retrusion, a correction of overjet, overbite and dental crowding in both arches, and a bilateral molar and canine class I has been achieved.Conclusion:Herbst appliance seems to be efficient in the correction of II Class Malocclusion, independently from patient’s cooperation; moreover , early correction of Class II malocclusion with functional appliances produces several clinical advantages.
