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.

ABSTRACT Objective: To evaluate the effect of the multiloop edgewise arch wire (MEAW) technique with maxillary mini-implants in the camouflage treatment of skeletal Class III malocclusion. Materials and Methods: Twenty patients were treated with the MEAW technique and modified Class III elastics from the maxillary mini-implants. Twenty-four patients were treated with MEAW and long Class III elastics from the upper second molars as control. Lateral cephalometric radiographs were obtained and analyzed before and after treatment, and 1 year after retention. Results: Satisfactory occlusion was established in both groups. Through principal component analysis, it could be concluded the anterior-posterior dental position, skeletal sagittal and vertical position, and upper molar vertical position changed within groups and between groups; vertical lower teeth position and Wits distance changed in the experimental group and between groups. In the experimental group, the lower incisors tipped lingually 2.7 mm and extruded 2.4 mm. The lingual inclination of the lower incisors increased 3.5°. The mandibular first molars tipped distally 9.1° and intruded 0.4 mm. Their cusps moved 3.4 mm distally. In the control group, the upper incisors proclined 3°, and the upper first molar extruded 2 mm. SN-MP increased 1.6° and S-Go/N-ME decreased 1. Conclusions: The MEAW technique combined with modified Class III elastics by maxillary mini-implants can effectively tip the mandibular molars distally without any extrusion and tip the lower incisors lingually with extrusion to camouflage skeletal Class III malocclusions. Clockwise rotation of the mandible and further proclination of upper incisors can be avoided. The MEAW technique and modified Class III elastics provided an appropriate treatment strategy especially for patients with high angle and open bite tendency.

A variety of treatment options may be implemented on a Class III malocclusion associated with skeletal discrepancy ranging from functional orthopedics at an early age to orthognathic surgery in adults. In the current scenario, many Class III malocclusion patients are referred for orthognathic surgery without even considering the options of an orthodontic camouflage, as orthodontists do not want to burden themselves with the tedious treatment planning and risks involved with treating such cases. This case report describes a 27-year-old female diagnosed with a skeletal Class III malocclusion, severe open bite, and periodontally compromised dentition. Although orthognathic surgery was proposed as the best treatment modality, it was denied by the patient due to financial and psychological constraints. She was treated with mild upper arch expansion using archwires and upper premolar intrusion using temporary anchorage devices (TADs) alongside retraction of lower anterior teeth using TADs and intermaxillary elastics. At the end of 18 months of active treatment, a decent result was achieved with good occlusion and facial esthetics. Post-treatment results showed an improved profile and Class I canine relationships, with optimal overjet and overbite. The anterior open bite was corrected, and the overall facial balance was greatly improved. Extraoral photographs displayed a relaxed lip closure and an esthetic smile meeting the patient’s expectations. Two-year follow-up records demonstrated a stable occlusion and optimal facial esthetics.

Class III malocclusions are considered to be one of the most difficult problems to treat. For us, the complex of these cases is the esthetic of the face and the smile because the treatment of the malocclusions without surgery produces a more retrusive face. We present a case report of an adult male patient with skeletal Class III malocclusion with compression in the maxilla and mandibular asymmetry, who has treated the orthosurgical approach. The result is acceptable in terms of occlusion-function, esthetic of the smile, and facial esthetics.

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.
