A skeletal Class III malocclusion with open bite tendency is considered very difficult to treat orthodontically without surgery. This case report describes the lingual orthodontic treatment of an adult skeletal Class III patient with mandibular deviation to the left side, lateral open bite, unilateral posterior crossbite, zero overbite and negative overjet. The lower incisors were already retroclined to compensate with the skeletal discrepancy. The patient was treated by asymmetric molar extraction in the mandibular arch to retract the lower incisors and correct the dental midline, with the help of intermaxillary elastics. Lingual appliance was used with over-torqued lower anterior teeth’s brackets to control the torque of mandibular incisors. After a 30-month treatment, satisfactory smile and facial esthetics and good occlusion was achieved. A 12-month follow-up confirmed that the outcome was stable. Asymmetric molar extraction could be a viable option to retract mandibular incisors in Class III malocclusion with lower dental midline deviation.

Skeletal Class III with openbite is one of the most difficult malocclusion to treat orthodontically. Generally, the morphological characteristics of this malocclusion are poor antero-posterior growth of the maxilla or excessive growth of the mandible with high angle. An 18-year-old male had Class III malocclusion with retrognathic maxilla and normal mandible with high angle. All third molars except on fourth quadrant were extracted to eliminate the posterior crowding. Multiloop Edgewise Arch-wire (MEAW) technique was used to upright the mesially inclined buccal teeth and to correct occlusal plane. In nine month time,  anterior cross bite and open bite were corrected; normal overjet, overbite and Class I canine relation were achieved.

Adult orthodontic patients with skeletal Class III malocclusion, open bite and bimaxillary dentoalveolar protrusion are complex problems that normally require surgical intervention to correct. This is a report of an adult female with a skeletal Class III jaw relationship; in addition, the patient had anterior open bite and bimaxillary dentoalveolar protrusion. The patient also had three premolars in the lower left quadrant. Treatment involved extracting the extra premolar distal to lower left canine, retraction of lower anterior teeth, closing extraction space and anterior open bite utilizing Invisalign clear aligners. The patient initially changed aligners every week before this was changed to 3–5 days after starting to use a high frequency vibration (HFV = 120 Hz) device. Satisfactory results were achieved in a relatively shorter period. Comparing before and after treatment cone beam computed tomography revealed that new bone has been formed labial to the lower incisors after their retraction/correction of their initial proclined position and the use of HFV and myofunctional therapy without gingival graft. The present case report shows the comprehensive multidisciplinary team approach in treatment for such cases and the advantage of using HFV to improve bone formation.

Introduction: This case report describes the treatment of a 21-year-old man who presented in an orthodontic office for treatment but lived in a city 100 miles away and wanted the orthognathic surgery in another state in America. The patient presented with an anterior open bite and skeletal Class III relationship. Methods: The treatment plan included: (1) effective and careful communication of the treatment plan with the patient, orthodontist and oral and maxillofacial surgeon; (2) pre-surgical alignment and levelling of the teeth in both arches with Invisalign; (3) a long-distance communication between the orthodontist and the surgeon for surgical plan with virtual surgical planning (VSP Orthognathics; 3D Systems, www.3Dsystem.com ) online; (4) maxillary advancement (LeFort I osteotomy) with mandibular set-back (bilateral sagittal split osteotomy); (5) postsurgical correction of the malocclusion with clear brackets and aligners; and (6) retention and final small tooth movement adjustments with aligners/clear retainers. Results: The anterior open bite was treated, crowding was eliminated in the upper and lower anterior segment, correction of skeletal and dental Class III malocclusion was obtained, mandibular plane angle was reduced and facial profile improved. Conclusions: The results suggest that aesthetic and functional results can be achieved with long-distance communication of two specialties and with the combined use of clear aligners and clear fixed appliances.

Pendahuluan: Perawatan ortodonti kamuflase adalah perawatan untuk menyamarkan diskrepansi skeletal dengan mengubah posisi dan angulasi gigi-gigi pada lengkung rahang. Perawatan tersebut merupakan perawatan yang dapat dipilih selain bedah ortognatik bagi kasus maloklusi skeletal kelas III pada pasien dewasa. Maloklusi skeletal kelas III sering pula disertai dengan keadaan lain seperti gigitan terbuka anterior yang menambah kompleksitas modalitas perawatan. Tujuan laporan kasus ini untuk menjelaskan pilihan modalitas perawatan pasien maloklusi skeletal kelas III secara kamuflase ortodonti. Laporan kasus: Pasien wanita usia 19 tahun 2 bulan datang ke klinik Ortodonti RSGM FKG UI dengan keluhan gigi atas depan tidak teratur dan gigi depan atas dan bawah tidak bertemu. Diagnosis menunjukkan pola skeletal kelas III dengan posisi maksila dan mandibula terhadap basis cranii retrognati (SNA 73°, SNB 74°, ANB -1°)  disertai dengan crowding sedang dan gigitan terbuka anterior. Tipe wajah pasien dolikofasial, simetris dan seimbang. Profil jaringan lunak dan skeletal cekung. Kasus ini dirawat dengan pendekatan ortodonti kamuflase tanpa pencabutan menggunakan piranti cekat standar Edgewise untuk mengoreksi crowding pada lengkung gigi atas dan bawah serta gigitan terbuka pada regio anterior. Perawatan ortodonti selesai dalam waktu 13 bulan dan crowding pada lengkung gigi atas dan bawah serta gigitan terbuka pada regio anterior telah terkoreksi. Simpulan: Perawatan ortodonti kamuflase pada maloklusi kelas III skeletal dengan gigitan terbuka anterior ringan merupakan pilihan perawatan yang cukup baik karena dapat mengoreksi maloklusi dengan kompensasi dentoalveolar sehingga diperoleh oklusi yang baik dan stabil. Hasil perawatan menunjukan hasil yang cukup baik dan dapat diterima oleh pasien.Kata kunci: Maloklusi skeletal kelas III, crowding, open-bite anterior, standar edgewise, ortodonti kamuflase. ABSTRACTIntroduction: Orthodontic camouflage is a treatment to disguise skeletal discrepancies by changing the teeth position and angulation in the jaw arch. This treatment is an option other than orthognathic surgery for skeletal class III malocclusion in adult patients. Skeletal class III malocclusion is often accompanied by other conditions such as an anterior open-bite which adds the complexity of the treatment modality. This case report was aimed to describe the choice of treatment modality for skeletal class III malocclusion patients by orthodontic camouflage. Case report: A female patient aged 19 years and two months came to the Orthodontic Clinics at the Faculty of Dentistry of University of Indonesia Dental Hospital (RSGM FKG UI) with complaints of irregular maxillary anterior teeth, and the maxillary and mandibular anterior teeth did not overlap. The diagnosis showed a skeletal class III pattern with the maxillary and mandibular position against the retrognathic cranii base (SNA 73°, SNB 74°, ANB -1°) accompanied by moderate crowding and anterior open-bite. The patient’s face type is dolichofacial, symmetrical and balanced, with the concave soft and skeletal tissue profiles. This case was treated with a non-extraction camouflage orthodontic approach using the standard edgewise fixed appliance to correct crowding in the maxillary and mandibular dental arches and open-bite in the anterior region. The orthodontic treatment was completed within 13 months, and crowding in the maxillary and mandibular dental arches and open-bite in the anterior region were corrected. Conclusion: Camouflage orthodontic treatment is a good treatment option for skeletal class III malocclusion with a mild anterior open-bite because it can correct malocclusion with dentoalveolar compensation to obtain a good and stable occlusion. The treatment results show good results and can be accepted well by the patient.Keywords: Skeletal class III malocclusion, crowding, anterior open-bite, standard edgewise, orthodontic camouflage.
