The present case report describes a conservative and uncommon treatment for class III malocclusion in a woman growing patient with aged eight years and four months. An unconventional treatment modality was used for the treatment of this malocclusion, reverse-pull headgear and distalisation of lower teeth using mandibular cervical headgear in the lower arch. At the end of the treatment (after 33 months), there was correction of the transversal and sagittal occlusal relationship between maxilla and mandible and correct dental intercuspation. Keywords Class III malocclusion; Open-bite; Orthodontics.

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.

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.

ABSTRACT Treatment of hyperdivergent skeletal Class III malocclusion is challenging for orthodontists, and orthognathic-orthodontic treatment is usually required. This report presents the successful nonsurgical treatment of a 20-year-old man who had a skeletal Class III malocclusion with anterior open bite, anterior and posterior crossbite, hyperdivergent growth pattern, steep occlusal plane, early loss of three first molars, and an uncommon convex profile with a retruded chin. An orthodontic camouflage treatment plan was chosen based on the etiology and the patient's complaints. Tooth #37 was extracted. Miniscrews were used for uprighting and intruding of the lower molars, distalization of the lower dentition, and flattening of the occlusal plane. After 34 months of active treatment, Class I relationships, proper anterior overjet and overbite, flat occlusal plane, and an esthetic facial profile were achieved. The results demonstrated that the biomechanics involved in the nonsurgical treatment assisted with miniscrews to distalize the mandibular dentition and flatten the occlusal plane while keeping the mandibular plane stable was effective for treating this hyperdivergent skeletal Class III patient with a convex profile and anterior open bite.

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.

A forward functional shift of the mandible is a significant problem that can cause both functional and aesthetic complications for many patients. This shift usually occurs in growing patients, and it is unusual to see in adult patients. This case report shows an adult patient with a forwarding functional shift that caused both anterior and posterior crossbites with a pseudo class III dental and skeletal relationship. The patient also showed severe upper arch crowding with blocked-out canines and mild crowding in the lower arch. The treatment of this patient involved extraction of the upper right and left first premolars and the lower right first premolar, followed by opening of the bite to relieve the neuromuscular reflex of the forward protrusion of the mandible during centric occlusion and to correct both the anterior and posterior crossbites. Extraction spaces were closed using class III elastics and elastomeric chains. At the end of the treatment, good functional and aesthetic results were obtained after the elimination of the forward functional shift.

Anterior open bite is a type of malocclusion in which there is the presence of a negative vertical overlap between the incisal edges of the upper and lower anterior teeth. It is considered a complex anomaly with distinct characteristics and difficult to treat with prevalence of 25% to 38% of patients orthodontically treated. The aim of this article is to report a clinical case of Class III right subdivision and open bite using 3DBOT technique, a fixed, comfortable, predictable, imperceptible technique with 3D technology and with extreme clinically proven satisfaction. Case report: Patient V.B.V.S., 23 years and 1 month old, leukoderma, male, mild dholico, straight profile, symmetrical, Class ¼ of Class III of molar and canine right subdivision, anterior open bite, inverted smile, mild upper and anterior dental crowding. Treatment plan: The use of 3DBOT was planned along with the use of intermaxillary elastics and refinement with the aid of MyAligner® aligners. Conclusion: The 3DBOT technique showed to be a viable option for treating anterior open bite
