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.

Mandibular Retrognathism

Skeletal Class II malocclusion is attributed to maxillary prognathism, mandibular retrognathism or combination of both. In adolescent cases, the treatment includes growth modulation with headgear or myofunctional appliances. However in adults, optimum esthetic and functional efficacy can be achieved by orthodontic-surgical combination. This case report describes a 21 years old post-pubertal male with severe skeletal Class II discrepancy with normal maxilla and retrognathic mandible. The case was treated with bilateral sagittal split osteotomy (BSSO) with mandibular advancement approach. Straight profile, pleasing esthetics, bilateral Class I molar and canine relationship, normal overjet and overbite were achieved because of a combined ortho-surgical approach.

This paper describes an adult Saudi male patient who presented with a severe skeletal class II deformity. The case was managed with a combination of presurgical orthodontic treatment followed by a double jaw orthognathic surgery and then another phase of orthodontic treatment for final occlusal detailing. Extraction of the four first premolars was done during the presurgical orthodontic phase of treatment to decompensate upper and lower incisors and to give room for surgical setback of the maxillary anterior segment. Double jaw surgery was performed: bilateral sagittal split ramus osteotomy for 8 mm mandibular advancement combined with three-piece Le Fort I maxillary osteotomy, 6 mm setback of the anterior segment, 8 mm impaction of the maxilla, and 5 mm advancement genioplasty. Although the anteroposterior discrepancy and the facial convexity were so severe, highly acceptable results were obtained, both esthetically as well as occlusally.

Abstract Background: To retrospectively evaluate postsurgical stability and condylar morphology for skeletal class II malocclusion patients with condylar resorption (CR) treated with orthognathic surgery.Methods: Thirty-five patients treated with combined orthodontic and orthognathic surgery between 2014 and 2018 were enrolled in this retrospective study. CT scans were acquired preoperatively (T0), 2–7 days after surgery (T1), and 1 year postoperatively (T2). The amount of mandibular advancement, postsurgical relapse, condylar morphology and joint spaces were analysed respectively. Statistical analysis was performed using R, version 3.4.3 (R Development Core Team 2010).Results: The average mandibular advancement and counter-clockwise rotation were 5.51 mm and -2.82 degrees respectively. The average relapse was 1.08 mm (19.6% of the advancement) and 1.13 degrees. The condylar volume showed a postoperative reduction of 161.86 mm3(13.7% of initial condylar volume). AJS increased after surgery and gradually returned to its original state, while SJS and PJS decreased and remained stable. Surgical advancement of B point was significantly correlated with skeletal relapse. The optimal cut-off values were as follows: MP-FH (40.75°); ramus height (51.125 mm); SJS (1.63 mm); surgical displacement (4.72 mm); CCR (-4.3°); AJSC (1.07 mm).Conclusions: Skeletal class II patients with CR have a high risk of postsurgical condylar resorption, which was most related to nonsurgical risk factors such as gender(female) and condylar angle. Condylar had moved posteriorly to the concentric position after surgery and remained quite stable through the 1-year follow-up. Preoperative skeletal patterns such as lower ramus height and surgical procedures such as larger advancement of the mandible were closely associated with sagittal relapse of the mandible.

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.
