The prevalence of skeletal Class II malocclusion is high amongst Asian population. Various treatment modalities have been presented for the treatment of Class II malocclusions in adult patients. We come across many adult patients who desire a costeffective and non-surgical correction and they accept dental camouflage as a treatment option to mask skeletal discrepancy. This case report presents a 26-year-old non-growing female who had a skeletal Class II malocclusion with prognathic maxilla and retrognathic mandible with an overjet of 7 mm, severe crowding, but did not want surgical treatment. We considered the camouflage treatment by extracting upper first premolars. Following the treatment, a satisfactory result was achieved with an acceptable static and functional occlusion, facial profile, smile and lip competence with patient satisfaction.

Abstract This case report describes the treatment of a case involving a skeletal Class II facial profile with a gummy smile. While treating a facial profile and a gummy smile, the outcome may not always be successful with orthodontic therapy alone. For this reason, surgical therapy is often chosen to gain an esthetic facial profile and a good smile. However, sometimes the patients reject surgical treatment and an alternative method must be considered. Skeletal anchorage systems such as miniscrews are now frequently used for correcting severe malocclusion that should be treated by surgical therapy. In this case report, we treated a skeletal Class II malocclusion with a convex profile and a gummy smile using miniscrews, which were placed in the upper posterior and anterior areas. The active treatment period was 3.5 years, and the patient's teeth continued to be stable after a retention period of 36 months.

Class II malocclusion in pubertal phase presents a major and a common challenge to orthodontists. Proper diagnosis and treatment planning in early stage help in preventing and intercepting the severity of malocclusion. In pubertal phase skeletal Class II malocclusion due to mandibular retrusion are best treated with functional appliance. In recent time PowerScope fixed functional appliance is gaining immense popularity as noncompliant Class II corrector. In the present case report an adolescent male patient having Class II division 1 malocclusion with functional jaw retrusion was treated using MBT 0.022” prescription and PowerScope appliance. 7-8 months of PowerScope wear obtained stable and successful results with improvement in facial profile, skeletal jaw relationship and mild increase in IMPA. It can thus be concluded that PowerScope gives good results in Class II correction with a combination of patient comfort and ease of use that was unmatched among other appliances

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.

AbstractOrthodontic-surgical treatment with the “Surgery First Approach” provides immediate facial aesthetic improvements and significantly reduces the patient's orthodontic treatment time, avoiding the transient worsening of the facial profile due to dental decompensation that occurs in surgical cases. Thus, this clinical case describes the retreatment of a 22-year-old female leukoderma patient, whose main complaint was related to the proclination of upper and lower incisors. The patient used a mio-relaxing plate for 30 days, which evidenced the skeletal mandibular deficiency and the ½ bilateral Class II malocclusion. Orthognathic surgery first approach associated with the extraction of the 4 premolars was chosen considering the patient’s aesthetic demand. The use of a mio-relaxing plate in the diagnostic stage was essential for the real diagnosis of mandibular deficiency and the technique employed made it possible to conclude the treatment avoiding aesthetic commitment, with excellent results.

ResumoO tratamento ortodôntico-cirúrgico por meio do benefício antecipado proporciona melhorias estéticas faciais imediatas e reduz de maneira significativa o tempo de tratamento ortodôntico do paciente, evitando a piora transitória do perfil facial devido à descompensação dentária que ocorre em casos cirúrgicos. Assim, este caso clínico descreve o retratamento de uma paciente com 22 anos de idade, leucoderma, sexo feminino, que apresentava queixa principal relacionada à inclinação vestibular dos dentes anteriores. Após uso de placa miorrelaxante por 30 dias, verificou-se a presença de Classe II esquelética com deficiência mandibular e ½ Classe II dentária bilateral. Considerando a demanda estética da paciente, optou-se pela abordagem ortodôntico-cirúrgica com Benefício Antecipado associada à extração de 4 pré-molares para correção da inclinação dentária anterior. O uso da placa miorrelaxante foi fundamental para o diagnóstico real da deficiência mandibular e a técnica empregada possibilitou concluir o tratamento evitando o comprometimento estético pré-cirúrgico, com obtenção de excelentes resultados.
